Operating instructions

12.
FOR COOLED AND DEHUMIDIFIED AIR set the thermo-
stat dial to the desired temperature. The warmest setting
(WARM) on the dial is approximately 95 degrees;
the
coolest setting (COLD) is approximately 70 degrees.
Place blower selector switch in desired position. High-cool,
medium-cool or low-cool positions are used when air condi-
tioning is desired. In these positions, the blower will operate
continuously and the compressor will come on when the
thermostat calls for cooling and off when the desired tem-
perature has been
reached.
FOR CIRCULATED AIR ONLY place the selector switch in
the desired position. High Fan, Medium Fan and Low Fan
positions will circulate inside air and not operate the com-
pressor for cooling.
FOR HEATED AIR, with the optional heat package instal-
led, place selector switch in the desired position. High Heat,
Medium Heat and Low Heat positions will circulate the
air
and allow the heater to cycle on the thermostat that has
been set at the desired temperature. Since actual BTU out-
put is not affected by blower speed, it is recommended that
Low Heat position be used. NOTE: On units that do not
have the optional heat package installed, these positions
will act to circulate the inside air only.
Adjust the louvers at the air discharge openings for best air
(These louvers should never be completely
TO COMPLETELY SHUT DOWN THE UNIT, place the
blower switch in the “OFF” position.
NOTE: Shur-Start models have a delayed start kit installed.
When the unit is turned on, the fan will start and in approxi-
mately two (2) minutes, the compressor will start. After the
compressor has shut down, it will not restart for approxi-
mately two (2) minutes. This allows pressures to equalize
in the refrigerant system and eases the starting load for the
compressor.
Quick-Start models do not have the delayed start feature.
When the unit is turned on, the fan and compressor start at
the same time. After shutdown, wait three (3) to four (4)
minutes before restarting unit to allow pressure equalization.
