RoomHeatPumps
Heatpumpsworkbymovingheatinsteadofcreatingit. Inthe
summer, the cool indoor coil absorbs heat from your room
andmovesitoutdoors,providingcooling.Inthewinter,heat
pumpsreversethisoperation.Byloweringthetemperature
of the outdoor coil below the outdoor temperature, the heat
pump absorbs the heat from outdoors and moves it inside
yourhouse.Thisheat transferringprocessisveryefficient.
Forexample,at45°Foutdoortemperature,aheatpumpcan
provide 2 ½ watts of heat for every watt of electricity it
consumes.
As outdoor temperatures drop, the heating capacity and
efficiencyoftheheatpumpdeclines. Attemperaturesbelow
45°F, it is likely that ice will form on the outdoor coil. Heat
pump units are designed to operate as a heat pump above
approximately 40°F. Below 40°F, these units switch auto-
matically from reverse cycle heat pump to auxiliary electric
heating.No defrost is required.There is no minimum
operatingtemperature.
NormalCareandMaintenance
Installing anair conditioner through a wall
requires extensive carpentry and/or mason-
ry experience. Thru-wall installations per-
formed by inexperienced or unqualified
individuals can result in costly damage to
home.
CAUTION
AnnualInspection
Itis suggested that yourunit be inspected byyourdealer or
servicer once a year.It is advisable to have the outer case
removedandtheunitthoroughlycleaned.
Underwriters Laboratories (UL) and the National Electric Code
(NEC) now require power cords that sense current leakage to
be able to open the electrical circuit to the unit. In the event, the
unit does not operate, check the reset button located on or near
the head of the power cord as part of the normal troubleshooting
procedure.
To avoid property damage, personal injury
or death due to electrical shock, turn unit
OFF and remove plug from wall outlet before
inspecting unit or performing maintenance.
