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.
Use copper wire only. Consumer’s responsibility is to provide
proper and adequate receptacle wiring that conforms to all
applicable codes. All wiring should be installed by qualified
electrician.
Installation
Complete step-by-step installation instructions are furnished
with your unit. These instructions will be found on a separate
page included with this manual or in the mounting kit
assembly. Follow these instructions carefully. Keep these
instructions with this manual for future reference. Your unit
will be one of the following three designs:
•
Unit with a window mounting kit
These models are designed for mounting though an
opening in a wall. These units can be adapted to
window installation by using the optional window mount-
ing kit supplied with your unit.
•
Unit without a window mounting kit
No window mounting kit is supplied with the unit.
These models are designed for mounting through an
opening in a wall. These units can be adapted to
window installation by purchasing an optional window
mounting kit. Consult your dealer to choose the kit that
is appropriate for your model and installation.
•
Unit with a separate sleeve
Some Builder models are designed such that the outer
case and the chassis can be purchased separately.
Through-the-wall installation instructions are included
with the outer case. These models can be adapted to
window installation by purchasing an optional mount-
ing kit.
Room Heat Pumps
Heat pumps work by moving heat instead of creating it. In the
summer, the cool indoor coil absorbs heat from your room
and moves it outdoors, providing cooling. In the winter, heat
pumps reverse this operation. By lowering the temperature
of the outdoor coil below the outdoor temperature, the heat
pump absorbs the heat from outdoors and moves it inside
your house. This heat transferring process is very efficient.
For example, at 45°F outdoor temperature, a heat pump can
provide 2 ½ watts of heat for every watt of electricity it
consumes.
As outdoor temperatures drop, the heating capacity and
efficiency of the heat pump declines. At temperatures below
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
operating temperature.
Normal Care and Maintenance
To avoid property damage, personal injury
or death due to electrical shock, turn fan
control OFF and remove plug from wall
outlet before inspecting unit or performing
maintenance.
WARNING
Annual Inspection
It is suggested that your unit be inspected by your dealer or
servicer once a year. It is advisable to have the outer case
removed and the unit thoroughly cleaned.
Note: The life of your unit may be greatly reduced if you live
in a salt air or other corrosive type environment. Under these
conditions, the unit should be removed from its case and
completely cleaned at least once a year. At that time any
scratches or blisters on the painted surfaces should be
sanded and repainted. Placing an algaecide tablet in the
outdoor side of the unit’s basepan is suggested in humid
areas where algae formation is common.
