MAXXFAN® / MAXXFAN® Plus
Can the lid of the MAXXFAN be open when driving?

Yes, the MAXXFAN and MAXXFAN Plus are designed with dual lifting arms to fully support the lid if installed properly. This makes the lid very sturdy and able to withstand high driving speeds when left open, it also prevents the lid from vibrating and rattling during high winds when the RV is parked. Be sure to fully open the lid when driving so the dual lift arms provide the maximum support for the lid.

Does the translucent white or smoke-tinted lid allow in more light?

Both lid colors will let light into the RV.  The smoke-tinted lid is similar to sunglasses or tinted windows and will allow more light and heat into the RV.  Both lids are designed with materials to provide long life in extreme sun and weather conditions.

How do I clean the screen on the MAXXFAN?

Simply rotate the four retaining knobs which hold the interior screen in place. The screen can then be rinsed off with water to clean. Mild detergent is also okay to clean stubborn grime on the screen.

I have the MAXXFAN Plus with the HandHeld Remote Control. Can I use the remote when I am outside of the RV?

No, the HandHeld Remote Control is infrared and only works when within line of sight of the MAXXFAN Plus.

I have the MAXXFAN Plus with the Rain Sensor option, can I still use the fan in light rain?

The Rain Sensor has a ‘disable’ function. Simply activate the ‘disable’ function and the MAXXFAN will stay open and continue operating even if the Rain Sensor is wet. Use caution when disabling the Rain Sensor as water may enter the RV.

I have the MAXXFAN Plus with the Rain Sensor option, can I still install a vent cover over the fan?

Yes, even with the Rain Sensor option it is perfectly acceptable to install a FANMATE Rain Cover over your MAXXFAN or MAXXFAN Plus. The FANMATE will allow the MAXXFAN to continue to be operated even when it is raining while protecting your RV from rain intrusion.

I have no room behind the area where I intend to install a MAXXFAN Deluxe. Can I install the MAXXFAN Deluxe sideways or with the rain shield area to the front of the RV?

The MAXXFAN Deluxe is only designed to be installed with the rain shield area pointing to the rear of the RV (hinge toward the front). If you do not have room for the overhang of the MAXXFAN Deluxe lid we recommend installing a MAXXFAN or MAXXFAN Plus with our FANMATE Rain Cover for great ventilation with rain free operation.

I have the MAXXFAN Deluxe with the HandHeld Remote Control. Can I use the remote when I am outside of the RV?

No, the HandHeld Remote Control is infrared and only works when within line of sight of the MAXXFAN Deluxe.

The Fan is making noise?

– If you are suddenly hearing a high pitch noise from the fan it is possible that the motor brushes need some cleaning. To clean the motor please proceed as shown in the video instructions.
Always remember to disconnect power supply before access the appliance.
– If you find the noise coming from the fan blade touching the housing, you can try to disassembly the fan and reassembly in the correct position.
Always remember to disconnect power supply before access the appliance.

The cover is making noise (rattling) while driving or in high wind conditions?

– Try to close better the lid (using the electronic motor if present). the MAXXFAN Deluxe is designed with dual lifting arms to fully support and close the lid if installed properly.  This makes the lid very sturdy and able to withstand high driving speeds, preventing the lid from vibrating and rattling.  Be sure to fully open or close the lid when driving so the dual lift arms provide his maximum function for the lid.
– The lid is made to work in fully open or fully closed position. Be sure to fully open or close it.

Maintenance Questions
What type of maintenance does my RV air conditioner require and how often should I perform it?
  • The motors are sealed and lubrication is not required.
  • Clean the outside (condenser) coil at least once a year. Gently blow out any debris, which may have collected on the coil, and straighten any fins that may be bent. Since the A/C fan pulls air in through the back of the coil and exhausts it from the sides of the shroud, an obstruction of this airflow will directly affect the performance of the unit.
  • You may also wash this coil with water if you choose to do so, but DO NOT use a pressure washer. Please remember to disconnect ALL power to the vehicle/air conditioner first.
Do I need to check or add refrigerant to my air conditioner periodically?

No. Your Coleman®-Mach® air conditioner is a closed and sealed system and ideally should never require refrigerant recharging. Should you suspect that you have a low refrigerant charge, have the unit evaluated by a qualified service technician.

How often can I expect to have my air conditioner serviced?

At RV Products, we have built more than five million RV air conditioners. A great many of them have never required service. However, as with any mechanical device, problems sometimes occur which require service or repairs. This type of service should always be performed by qualified service personnel.

What size/how many BTU's is my air conditioner?
  • Retrieve the complete air conditioner model (if you are unsure how to locate the unit model number, access the link below to help you in obtaining this number). This link allows you to see where the rating plate sticker is located. (https://www.airxcel.com/coleman-mach/service-support/where’s-my-model-number)
  • Once you have the model number, go to our Document Library, key the model number into the search engine on our Literature and Technical Documents page.  You will find a large selection of information available for your air conditioner. (https://www.airxcel.com/coleman-mach/service-support/document-library)
Electrical Questions
What is the proper operating voltage for a domestic RV air conditioner?

Proper operating voltage is 115 VAC/60Hz. The unit may be run safely between 104 volts and 125 volts. Do not operate the air conditioner outside of these parameters, as serious component damage may result.

How much electrical power (amps/watts) does my air conditioner use? What size generator do I need?
  • Air conditioners are designed under specific operating conditions reflecting average use. The specification charts listed (data tag) with each model reflect that model’s power consumption at these design temperatures only. Design temperatures for most Coleman®-Mach® RV air conditioners are 95° F. outdoor temperature, 80° F. indoor temperature and 50% relative humidity.
  • We are aware that the conditions under which our air conditioners might be operating may vary considerably from these design parameters. We do not size generators. However, to access information on sizing the units or amp draws, access the Document Library on our webpage (the link is provided below). In the Document Library, type your model number in the search engine and locate the data sheet.
    • To calculate the max potential startup: Find the running amp draw for your system and multiply it by 2.5. With this information, your generator manufacturer should be able to assist you in sizing a generator suitable for your application. (http://www.airxcel.com/coleman-mach/service-support/document-library).
The circuit breakers in my RV have been tripping while my air conditioner is in use. What could be the problem?
  • This is a very broad subject with many possible answers. Some of the most common include:
  • The supply voltage may be too low (see Question 2 in this section).
  • Too many electrical loads on the vehicle’s 30-amp power supply such as refrigerators, converters, coffee pots, microwaves, electric water heaters, etc. will cause a voltage drop.
  • Long extension cords. For assistance in proper sizing of power cords, consult with your RV dealer or service center.
  • Airflow through the outdoor coil (condenser coil) may be obstructed by debris, or the cooling fins may be bent.
  • If you have eliminated the problems listed above, you may have a more serious issue that would require evaluation by a trained technician.
What about extension cords?

Light gauge and/or long extension cords tend to cause significant voltage drops to the vehicle/air conditioner. If used, the extension cord should be sized to maintain proper voltage at full load conditions. Serious component damage may occur if the air conditioner is operated under low voltage conditions (see Question 1 in this section). Neither 115-volt “cheater” plugs or 15-amp outlets are recommended.

Cooling Questions
Does the refrigerant in my air conditioner need to be changed?

No. Refrigerant will not become old or wear out. It is intended to last the lifetime of the unit.

What temperature (how cold) should the air supply be?
  • Unfortunately, there is not an easy answer to this question. The supply air temperature will vary somewhat proportionally with the temperature of the air being pulled through the return air grille(s) of the air conditioner. Additionally, the outdoor air temperature, humidity, air volume and even proper air conditioning maintenance all have an effect on the air conditioner supply air temperature.
  • An ideal cooling system should give you an output temperature range of 16-22 degrees lower than the temperature taken in at the filter. Humidity is a significant determining factor in this temperature difference.
  • You can test the temperature difference by taking a reading at your filter and the first register where air is leaving the system. Please use the same thermometer at each location.
What would cause my air conditioner to "freeze up" with ice?

To answer this question, you must understand; air conditioner capacities are rated primarily by their ability to transfer heat from the inside of your vehicle to the outside air. Your air conditioner may freeze up if it fails to pick up or transfer heat for any of the following reasons:

  • Indoor and outdoor temperatures may be too cold (lack of heat).
  • Evaporator air recirculation is possible due to poor or improper installation.
  • Airflow obstructions:
    • Dirty filters. Filters should be cleaned regularly.
    • Supply air louvers may be shut off.
    • Inadequate or damaged ducting (if so equipped).
    • Dirty or plugged cooling (evaporator) coils.
  • Low Fan Speeds (motor that is not pulling enough amps or airflow).
  • Improper Operation: Setting the temperature on the thermostat so low the compressor does not cycle off and on. Running the compressor and low speed fan together may cause “freeze-up” conditions to accelerate.
  • Electrical problems, faulty thermostat, inoperative freeze thermistor.
Heating Questions
What is the temperature range for my Heat Pump?

The Coleman-Mach heat pump is an effective heat source, as long as outdoor temperatures are above 45°F. Below 45°F, there is not enough heat outside for the system to absorb, and efficiency drops. With a lack of heat, you will run into a freeze up situation that will shut down your compressor, but leave the indoor blower running. We recommend that, if you know your outdoor temperatures are going to be below 45°F, simply heat the application with the LP furnace until the conditions are more ideal for the heat pump.

Why does my furnace come on when I am calling for heat pump?
  • When your thermostat is in the “Electric Heat” mode, if the set temperature is five or more degrees above what it shows as the room temperature; the thermostat will consider this too much of a load for an electric heat source and bring in the furnace to assist. The furnace will continue to run in this case, until the thermostat is satisfied. When the room temperature starts to drop again, the thermostat will try to proceed as normal, with just the electric heat (unless the difference between set point and room temperature reaches five degrees again).
  • PLEASE NOTE: Some of our thermostats will not run your electric heat and gas heat simultaneously. They will shut down the electric heat in order to bring in the gas heat.
  • Multiple consecutive calls for the furnace in the “Electric Heat” mode, can cause the thermostat to lock out the electric heat function for approximately two hours, triggering the furnace only when it needs heat. For more information on the Lockout function of the thermostat, click here.
Aqua-Hot Heating System Antifreeze
Terms
  • Antifreeze and Boiler antifreeze
    These two very different. Boiler anti-freeze is intended for use in boiler systems and has a different chemical composition than antifreeze intended for RVs, automobiles and trucks. Aqua-Hot offers Century Boiler Antifreeze in both green and pink, in 1 gallon and 32 oz options. If purchasing elsewhere, Camco has pink RV Plumbing and RV Freeze Ban antifreeze in addition to their pink boiler antifreeze; be sure to use the boiler antifreeze in your Aqua-Hot system.
  • Antifreeze and coolant
    These terms are typically used interchangeably. Aqua-Hot heating systems use boiler-designated antifreeze that is rated GRAS — Generally Regarded As Safe.
  • GRAS
    This is the Federal Drug Administration term for Generally Regarded As Safe. GRAS is the term to look for on antifreeze products. Anything else is likely to be harmful if swallowed.
  • Freeze Point is the temperature ice crystals will start to form in the antifreeze solution.
  • Burst Point is the temperature where damage will occur to the coach.
Types Of Antifreeze In Aqua-Hot Heating Systems

Propylene Glycol Boiler Antifreeze In 2002, Aqua-Hot changed the system design and in 2003 systems started using Propylene Glycol-based boiler antifreeze rated Generally Regarded AS Safe (GRAS).

All Aqua-Hot Systems manufactured after 2002 must use Propylene Glycol antifreeze, including Hydro-Hot™, Aqua-Hot 250P™, Aqua-Hot 250D™, Aqua-Hot 375D™, Aqua-Hot 375LP™, Aqua-Hot 400D™, Aqua-Hot 400P™, Aqua-Hot 450D™, Aqua-Hot 525D™, Aqua-Hot 600D™, and Aqua-Hot 675D™. DO NOT use Ethylene Glycol or Propylene Glycol automotive antifreeze in these Aqua-Hot systems.

Ethylene Glycol Antifreeze Ethylene glycol antifreeze is toxic, does not have the GRAS label and is not suitable for an Aqua-Hot system manufactured after 2002. Ethylene glycol was used in pre-2002 Aqua-Hot systems with the exterior domestic hot water loop design. Ethylene glycol can be used in these pre-2002 systems, as well as GRAS-labeled propylene glycol boiler antifreeze.

Why Does The Aqua-Hot System Use Boiler Antifreeze?

Unlike automotive antifreeze, boiler antifreeze has a higher boiling point and higher viscosity that helps lubricate the system, as well as the rust, scale and corrosion inhibitors. When properly used, it is capable of efficient and high heat transfer.

Aqua-Hot heating systems use either the Century or the Camco brand products. The color your system has depends on the coach manufacturer and the model year of your motorhome.

What Brands Of Boiler Antifreeze Are Recommended For Aqua-Hot Heating Systems?

Aqua-Hot heating systems typically use either the Century or the Camco brand products. The color your system has depends on the coach manufacturer and the model year of your motorhome. TIP: Don’t mix colors in your Aqua-Hot system. Mixing pink and green boiler antifreeze produces a brown color that may be confused with corrosion, creating unnecessary service expense.

How Do You Confirm Your System's Antifreeze?

You can check the antifreeze color by looking at the expansion bottle for your Aqua-Hot heating system or draining a little from the drain valve. Aqua-Hot heating systems typically use either the Camco (pink color) boiler antifreeze or the Century (green color) brand products. The color your system has depends on the coach manufacturer and the model year of your motorhome.

Where Do You Buy Boiler Antifreeze For Your Aqua-Hot System?

Camco pink boiler antifreeze is available directly from Aqua-Hot as well as most RV dealers. Century green is available directly from Aqua-Hot.

How Do You Check Your Aqua-Hot Boiler Antifreeze Fill Level and Percentage of Propylene Glycol?

Antifreeze Fill levels are visually checked at the expansion bottle when the Aqua-Hot system is warm and level; the proper fill level is at the HOT line.

Run your Aqua-Hot system to operating temperature. When it is warm and the coach is level, visually check the Aqua-Hot expansion bottle to see if the antifreeze solution is at the HOT mark. This gives you a true indication of the Aqua-Hot antifreeze solution level.

Check the percentage of propylene glycol antifreeze solution in your Aqua-Hot system with a calibrated coolant/antifreeze refractometer. Water will evaporate from the boiler antifreeze mixture over time, concentrating the antifreeze mixture and changing the ratio in the system.

The Aqua-Hot antrifreeze solution should fall between 35% and 50% propolyne glycol boiler antifreeze to water. Too much antifreeze lowers the heat transfer capability, causes sticking check valves in the heating zone lines and may coat the system’s interior surfaces resulting in lower water and interior cabin temperature levels. DO NOT exceed 50% propylene glycol in an Aqua-Hot system.

Antifreeze Discoloration

Discoloration of propylene glycol antifreeze solution may occur during normal operation of the Aqua-Hot system. This discoloration does not indicate a malfunction of the Aqua-Hot system or the antifreeze solution.

The following conditions may cause the antifreeze solution in your aqua-hot to change color:

Exposure of the antifreeze solution in the Aqua-Hot boiler tank to air
It is important to keep the overflow bottle filled to the proper level*. If the Overflow bottle is empty, it must be refilled and the tank must be bled of air*. Air in the Aqua-hot boiler tank may cause the antifreeze solution to discolor.
Low Levels of propylene glycol in the antifreeze and water solution
The Aqua-Hot’s antifreeze solution should contain between 35% and 50% propylene glycol. Operating the Aqua-Hot with less than 35% propylene glycol may cause the antifreeze solution to discolor. Please see the Aqua-Hot’s Owner’s manual for instructions on testing the level propylene glycol in the Aqua-Hot’s antifreeze solution*.
Adding Tap or Well Water to the Aqua-Hot system
Adding tap or well water to your Aqua-Hot system may cause the antifreeze solution to discolor. Aqua-Hot recommends using only deionized or distilled water. Using tap or well water may cause corrosion of the Aqua-Hot system.
Mixing Century Brand (Green) and Camco Brand (Pink) Boiler Antifreeze
Motorhome manufacturers generally fill the Aqua-Hot with Century brand (green in color) or Camco brand (pink in color) boiler antifreeze. Mixing these two colors together may cause discoloration of the antifreeze solution in your Aqua-Hot.

Discoloration of the Aqua-Hot’s antifreeze Solution does not indicate a malfunction of the Aqua-Hot system or the antifreeze solution.

*Please see Aqua-Hot Owner’s and Service Manuals for instructions concerning all of the above items. These Manuals are available on the library page at www.aquahot.com

Flushing the System

Aqua-Hot does not recommend draining and flushing the system unless the wrong type of fluids were added to the boiler fluid.
For example, if your system uses propylene glycol “GRAS” antifreeze, but ethylene glycol was mistakenly added, the system would need to be flushed for safety reasons.

How To Get The Boiler Antifreeze Mixture Right
Determine the level of freeze protection you require

Use the Propylene Glycol-Based Antifreeze Protection chart to determine the protection you require in your Aqua-Hot system. Freezing Points are temperatures at which ice crystals form. Even below those temperatures, a slushy condition exist which may flow. Burst point is the temperature where damage will occur to the coach; at antifreeze solution percetages above 35%, burst protection is below -50 degrees F.

The propylene glycol antifreeze level of the solution in the Aqua-Hot heating system needs to fall between 35% and 50%. The Freeze Point is the temperature at which ice crystals will start to form in the antifreeze solution. Burst Point is the temperature where damage will occur to the coach. DO NOT exceed 50% Propylene Glycol in an Aqua-Hot System.

Check Your Aqua-Hot Heating System Antifreeze Fill Level Monthly

Inspect your Aqua-Hot system monthly. Run your Aqua-Hot system to operating temperature. When it is warm and the coach is level, visually check the Aqua-Hot expansion bottle to see if the antifreeze level is at the HOT mark. This gives you a true indication of the antifreeze solution level.

When you need to add antifreeze, determine the freeze protection you need in the final antifreeze solution and mix your replenishment solution accordingly. This will require a refractometer for accuracy.

How To Determine The Percent Of Propylene Glycol In The Aqua-Hot System

After you obtain boiler antifreeze with the same color as your current system, it is critical that you determine the antifreeze mixture of the Propylene Glycol boiler antifreeze in your system. Water will evaporate from the boiler antifreeze mixture over time, concentrating antifreeze mixture and changing the ratio in the system.

Use a calibrated coolant/antifreeze refractometer and measure the ratio of Propylene Glycol in your antifreeze solution.

Caution: Automotive “ball type” hydrometers that measure ethylene glycol in the engine’s coolant system will not properly measure propylene glycol.

What Is The Correct Boiler Antifreeze Mixture Ratio?

The correct antifreeze solution mixture for protecting your Aqua-Hot system depends on where you are and how cold it is — or can be.

Use the Propylene Glycol-Based Antifreeze Protection chart to determine the protection you require in your Aqua-Hot system. Freezing Points are temperatures at which ice crystals form. Even below those temperatures, a slushy condition exist which may flow. Burst point is the temperature where damage will occur to the coach; at antifreeze solution percetages above 35%, burst protection is below -50 degrees F.

Aqua-Hot recommends the antifreeze solution contain between 35% and 50% propylene glycol boiler antifreeze to water mixture. Too much antifreeze lowers the heat transfer capability, causes sticking check valves in the heating zone lines, and may coat the system’s interior surfaces resulting in lower water and interior cabin temperature levels. DO NOT exceed 50% propylene glycol in an Aqua-Hot system.

Your Aqua-Hot Factory Authorized Service Center will assure the proper ratios. If you do it yourself, check the color.

What Happens If The Green And Pink Are Mixed?

Camco and Century may not honor the warranty of their product if mixed with another company’s product.

Motorhome manufacturers generally fill the Aqua-Hot with Century brand (green in color) or Camco brand (pink in color) boiler antifreeze. Mixing these two colors together may cause discoloration of the antifreeze solution in your Aqua-Hot.

How To Add The Fresh Antifreeze To The Antifreeze Solution

When your visual inspection level indicates a need to replenish the antifreeze solution:

  1. Use the same color boiler antifreeze that’s in your heating system.
  2. Determine the Propylene Glycol antifreeze protection level you want, using the chart below.
  3. Make sure you have the antifreeze amount you need to fill your system to the HOT mark on the expansion tank. See back for details on mixture for your color of antifreeze.
  4. Bring your heating system to operating temperature. This prevents the overflow that will happen when coolant is added to a cold tank.
  5. Remove the expansion tank cap. TIP: Solution in the system is very, very hot. Wear eye and skin coverings to protect against splashes or spray.
  6. When refilling, open the Air Release Valve located on the expansion tank connection on the Aqua-Hot system to release air pockets; close the release valve when antifreeze appears at the Air Release Valve. Fill until you reach the HOT mark on the expansion tank.
Fuel Filters
What type of fuel filter do I need?

Aqua-Hot carries two types of fuel filters. Please compare these two images with the fuel filter in your coach bay to determine which style you need.

Fuel Filters that utilize a clear bowl

These are discontinued fuel filters, if your clear bowl breaks, please order part number FLX-120-000 to convert to the current style. Part number FLX-120-000 includes mounting brackets.

What does the Low Temperature Cut-Off Thermostat light indicate?

LTCO (Low Temperature Cut-Off) Thermostat

200/250 Models: When the D4 (LTCO) light is off, the unit is up to temperature and ready to make interior heat. When the D4 (LTCO) light is on, either domestic water is being used, or the system is not yet fully up to temperature.

400/450 Models: A green LTCO light means that the heater is up to temperature and ready to make heat. When the LTCO light is not illuminated, either domestic water is being used, or the system is not yet fully up to temperature.

600/675 Models: The LTCO light will always be illuminated and does not impact hot water or heat functions.

General Questions
Disinfecting the Water System
Can I use biofuels in my diesel Aqua-Hot system?

Diesel fuel containing a maximum of 20% Biofuel, commonly known as B20, may be used in diesel Aqua-Hot systems. However, please note that it may be necessary to change the fuel filter more frequently as B20 slightly cleans the fuel system.
