Operating Instructions

The Coleman-Mach 48004-066 heat pump is controlled via a compatible RV thermostat (not included with the unit). Familiarize yourself with your thermostat's operation manual for specific controls.

Basic Operation:

• Power On/Off: Use the thermostat to turn the unit on or off.
• Mode Selection: Select desired mode (Cool, Heat, Fan Only) on your thermostat.
• Temperature Setting: Adjust the desired temperature using the thermostat controls.
• Fan Speed: Choose fan speed (High, Low, Auto) as available on your thermostat.
• Heat Pump Operation: In heat mode, the unit will extract heat from the outside air and transfer it indoors. Performance may decrease in very low ambient temperatures.
• Cooling Operation: In cool mode, the unit will remove heat from the indoor air and dissipate it outdoors.

For optimal performance, ensure all windows and doors are closed when the unit is operating in cooling or heating mode.

Maintenance

Regular maintenance ensures efficient operation and extends the lifespan of your heat pump. Always disconnect power to the unit before performing any maintenance.

Recommended Maintenance Schedule:

• Air Filter Cleaning (Monthly or as needed): The return air filter (located inside the RV, typically in the ceiling assembly) should be cleaned regularly. Remove the filter, wash it with mild soap and water, rinse thoroughly, and allow it to dry completely before reinstallation.
• Condenser and Evaporator Coils (Annually): Inspect the outdoor condenser coils and indoor evaporator coils for dirt and debris. Carefully clean them with a soft brush or coil cleaner if necessary. Avoid bending the fins.
• Drain Pan and Drain Holes (Annually): Check the condensate drain pan and drain holes for blockages. Clear any obstructions to ensure proper water drainage.
• Shroud Inspection (Seasonally): Inspect the outdoor shroud for cracks or damage. Replace if necessary to protect internal components.
• Electrical Connections (Annually): Have a qualified technician inspect all electrical connections for tightness and corrosion.

Do not use harsh chemicals or abrasive cleaners on any part of the unit.
