MANDALAY
NOTE: The discharge air will heat up faster if the blower is operated on lower speeds until the
engine is hot. For windshield de-icing, use DEFROST mode.
Keep the condenser and radiator free of bugs and debris. During periods of little use, operate
the A/C system monthly to keep the compressor lubricated. Periodically inspect belts and hoses
for wear and proper tension.
If repairs are necessary during the terms of the motorhome warranty, please contact the
nearest authorized Mandalay dealer for service. In the event repairs are necessary during
transit, contact Mandalay Customer Service. Certain individual parts of the Heating and Air
Conditioning System such as the compressor, dryer and condenser are covered under the
chassis manufacturer warranty.
NOTE: Components covered under the Mandalay Limited Warranty must be Original
Equipment Manufacturer (OEM) parts. The installation of after market components or
unauthorized repairs may void the warranty.
The motorhome is equipped with two (40E, 40G, &
40H) or three (43A, 43B & 43C) roof mounted air
conditioners. These air conditioner’s operate from
120 Volt AC only, either from shore power or the
on-board generator. Air conditioner functions are
controlled by the comfort control panel.
You can expect to see up to 18 to 20 degree differences in temperature between the closest
A/C outlet vent and the return air inlet grill under most operating conditions.
Factors that can affect the performance of the cooling system:
• Use window and patio awnings when outside ambient temperature is above
95° F to help deflect the Sun load during the heat of the day. If window
awnings are not installed then use shades or blinds to deflect the Sun.
• Try to avoid using the cooktop or oven when the ambient temperature is over
95° F.
• Keep windshield covered when facing the afternoon Sun when parked.
• The number of windows within the slideouts and the number of cold air
registers to handle heat gain when facing the afternoon Sun.
