Operating Instructions
Your Coleman-Mach 8 Plus Air Conditioner is controlled via a compatible thermostat (not included with the unit). Refer to your thermostat's manual for specific operating procedures.
Basic Operation
- Cooling Mode: Select "Cool" on your thermostat. Set the desired temperature. The unit will cycle on and off to maintain this temperature.
- Heat Pump Mode: Select "Heat" on your thermostat. Set the desired temperature. The heat pump will provide efficient heating.
- Fan Mode: Select "Fan" to circulate air without heating or cooling. Choose between high and low fan speeds.
- Auto Mode: Some thermostats offer an "Auto" mode, which automatically switches between heating and cooling to maintain the set temperature.
Condensate Pump
The integrated condensate pump automatically removes condensation from the unit during cooling operation. Ensure the condensate drain line is clear and properly routed to prevent water accumulation.
Maintenance
Regular maintenance ensures optimal performance and extends the lifespan of your air conditioner.
Air Filter Cleaning
- Locate the return air filter(s) inside the RV, typically behind the ceiling assembly grille.
- Remove the filter(s) and clean them with mild soap and water.
- Allow the filter(s) to dry completely before reinstalling.

Exterior Coil Cleaning
Periodically inspect the outdoor condenser coils for dirt and debris. Carefully clean with a soft brush or vacuum. Avoid bending the fins.
Roof Gasket Inspection
