xi. LED LIGHTS AND BUTTONS ON THE 

CEILING ASSEMBLY.

The ceiling assembly has a two color LED to indicate if 

the unit is in Cooling or Heating.  Two manual override 

buttons - one for cooling the other for heating – can be 

used if the remote controller is lost or malfunctions.

xii.  ROUTINE MAINTENANCE

One of the biggest advantages to your new Coleman-Mach 

heat pump is that the maintenance needed to keep the unit 

in good working order is minimal.  In fact about the only 

thing you, the owner, must take care of is the cleaning and 

replacement of the filters.

The ceiling assembly and the outside shroud can 

be cleaned with a damp cloth.  When required a mild 

detergent can be used.
Filters are made from long life non-allergenic natural 

fibers  which  can  be  cleaned  and  reused,  and  which 

completely filter the circulated air when the heat pump 

is in operation.  If the filters are not cleaned at regular 

intervals, they may become partially clogged with lint, 

dirt, grease, etc.  A clogged filter will produce a loss of 

air volume and may eventually cause an icing-up of the 

cooling (evaporator) coil.

IMPORTANT: 

Do not operate your heat pump for extended 

periods of time without the filter installed.

An even more serious condition occurs when the heat pump is 

operated without a filter.  When this happens the lint, grease, etc. 

that are normally stopped by the filter are now accumulating in 

the cooling coil.  This not only leads to a loss of air volume and 

a possible icing-up of the cooling coil, but could also result in 

serious damage to the operating components of the heat pump.

Cleaning and/or changing the filters:

1. 

Remove the two grilles from the ceiling assembly by 

pulling the tabs on the grilles as shown in illustration.

2. 

Remove and clean or replace the two filters.  The 

filters should be washed in warm water or vacuumed 

clean.  The filters should be inspected once a month 

and cleaned or replaced as required.

3. 

Re-install  the  filters  and  grilles  in  the  ceiling 

assembly.

NOTE:

 If the unit is operated in a dusty environment, the filters 

should be inspected and cleaned more frequently.
