and track arrangements, the above dimensions
may vary slightly. If necessary, the installation
can be made by altering the window jambs.
Alternate Window Jamb Applications
To install in windows having no flanges or wood stops on
the top and side jambs, the channels and panel frame
must fit against a mating flange (or 1/16-inch max. thick
angle) attached to the window jambs. Figure A shows
this angle installed. Figures B & C show alternate
treatments. On the sash side of the opening, the leading
corner of the inner sash becomes the flange. You can
purchase the angle strip locally.

4. Blown fuses.
5. Premature failure of compressor or fan motor.
6. Noticeable dimming of lights when unit is operating.
7. Evaporator icing, caused by low voltage reducing fan
speed resulting in an inadequate air flow over the
evaporator.
Low voltage will result from inadequately wired circuit,
extension cords, and loose fuses or connections in the
power supply. Voltage supplied by the electrical
company can also result in low power, (responsibility of
local power company.
All units will operate and run on minimum voltage stated
in "Air Conditioning Voltage Limits", and will perform
satisfactorily if voltage remains constant. Low voltage
caused by defective wiring will not remain constant under
load.
Testing for low voltage, use a reliable voltmeter with
sufficient capacity to measure the required voltage.
Verify voltage at electric power entry point and at
electrical outlet serving the unit Verify readings with the
unit off, while the unit is starting, and again while the unit
is operating. Lowest reading should not drop below the
lowest minimum value.
High Voltage
High voltage can be equally troublesome, causing motor
to overheat, cycle on their protectors, or break down
electrically. This problem can only be solved by the local
power company.
Electronic Control
Control is not repairable. If any component in the control
is defective, entire control must be replaced.
NOTE: Repair or replace any malfunctioning line voltage
component before testing or replacing the
electronic control. Do not assume service
problem is directly caused by the electronic
control system. A line voltage component
(including power cord and wiring) that has
opened, shorted, grounded or otherwise
malfunctioned, may have created a service
problem.
