IV. MAINTENANCE
One of the biggest advantages of owning a Coleman-Mach air
conditioner is that the maintenance needed to keep the unit in
good care is minimal.
In fact, the only maintenance that must be taken care of on a
regular basis, is the cleaning or replacement of the air
conditioner return air filters and condensate drain.
The manufacturer of your home determines the number, size
and location of the return air filters. Be sure to contact your
dealer should you have any questions concerning the number
of filters used and their location.
The return air filters of this system will accumulate dust and
dirt more quickly than ceiling mounted air conditioning
systems. We recommend that the filters be checked on a
weekly basis.
If the filters are not cleaned or replaced at regular intervals,
they may become partially clogged with lint and dirt. A
clogged filter will produce a loss of air volume and may
eventually cause equipment damage.
Do not operate the air conditioner without return air filters.
Operating the system without filters allows the lint and dirt
that is normally stopped by the filter to accumulate on the
cooling coil of the air conditioner. This also will lead to a loss
of air volume, possible equipment damage and an expensive
cleaning process.
Periodically (once or twice a season), inspect the outdoor coil
and brush off any accumulated residue with a soft bristled
brush.
The condensate tube and associated hose, if provided, should
be flushed once a season to remove any residue. The barbed
fitting may be easily pulled out of the rubber grommet at the
unit.
The 46413 series air conditioner uses R410A refrigerant with
a factory installed High Pressure Safety Circuit. In the event
of an abnormal condition (failure of fan motor, dirty
condenser coil, dirty filters) the high pressure switch will
prevent the compressor from continuing to run. Once the high
pressure switch has tripped, this safety circuit will “Lock Out”
the compressor and outdoor fan preventing them from trying
to restart or run. This is a manual reset pressure switch, access
shall be limited to Qualified Technicians. The pressure switch
manual reset button is accessed in the unit’s electrical box thus
the high voltage power must be turned off before opening
panel and resetting switch.
