refrigeration units, it's
important to wear
protective clothing. It's
important toprotect
yourself from battery acid,
hot coolant, refrigerants, refrigerant oils, flying dirt.
debris, and noise.
High Voltage
When working on all-electric units
you may beexposed to high
voltage. To work safely on this
equipment, you MUST fully
understand and follow safe
electrical work practices.
Toxic Gas
Frostbite
Liquid refrigerant in contact with your skin will
cause severe injury. Always wear eyeprotection
and protective clothing and use extremecare when

produce toxic gases.
These gases are severe
respiratory irritants
capable of causing death.
Usecaution when working
with refrigerant in aclosed
orconfined area with a limited air supply such as a
trailer, container or hold of a ship. Refrigerant
displaces air and can cause death due to suffocation.

Cool Mode Operation
1. Select “COOL”mode to turn on air conditioning.
2. Set desired temperature on control panel.
3. Select desired blower speed with slide bar on control panel.
4. Auto mode when selected will select a fan speed depending upon the difference between the set temperature
and ambient room temperature. Will control the temperature within ± 2°of set point.
Maintenance
Return Air Filter Cleaning (FIGURE #1):
1. Turn system off.
2. Turn knobs counter-clockwise ¼ of turn to remove intake grill and filter.
3. Remove dirt and dust from filter with vacuum and wash filter with soap and water. Filter should be
cleaned once a month during normal conditions and daily or weekly if conditions are warranted.
Note: Never run the air conditioner without the return air filter. Running the air conditioner without a
filter may allow the evaporator coil to be plugged with dirt which will affect the performance of the air
conditioner.
Condenser Coil Cleaning: It is recommended that you clean the condenser and fins every year with
soapy or non-acid coil cleaning liquid in normal conditions or more frequently in extreme conditions to
maintain the efficiency of your RV air conditioner. Eventually, if not cleaned properly the condenser fins
may become clogged with dirt and dust. Do not use high pressure water or steam to clean condenser
fins.

Warranty Procedures
1. Prior to starting warranty work, the repair facility must contact ProAir by calling 574 264 5494 or 800 338 8544,
asking for the customer service department or by faxing the Warranty Checklist. See ProAir Checklist on page 14.
The following information is required: ProAir serial number and model number, vehicle identification number (VIN),
mileage, retail purchase date, and retail customer’s name. The ProAir serial number label (FIGURE #3) is located on
the backside of the rooftop unit main plate and is visible when removing the filter from the plenum. This information is
very helpful when requesting warranty parts or technical assistance.
2. Describe the problem or type of warranty repair needed. Our customer service specialists are trained on ProAir’s
products and can assist you in diagnosing the problem.
3. If parts are required, ProAir reserves the right to supply any and all warranty parts.
4. All warranty parts are shipped on a memo (no-charge) billing and are sent the same day if possible. An
authorization number accompanies the replacement parts. Also noted on the memo billing is our labor allowance for
the repair; labor allowances are based on ProAir’s flat-rate standards multiplied by the repair facility’s standard retail
labor rate. All defective parts shall be returned to ProAir; shipping charges—by the most economical method—may be
added to the cost of the repair. No warranty claims will be paid without the return of defective parts.
5. Warranty claims submitted to ProAir must include the following: ProAir authorization number, ProAir serial
number, vehicle identification number, mileage, and authorized labor amount. ProAir does not pay tax or
miscellaneous shop supplies. All claims must be submitted within 30 days of the date of repair, and all parts must
be returned in order to receive payment on these warranty claims.
6. ProAir reserves the right to deny any claims without the proper documentation or claims that were for improper
repairs. Service management is responsible for implementing controls to eliminate improper or unnecessary repairs
and providing accurate information on the claims. This includes a complete and clear description of the vehicle’s
concern and required repairs.
