ROCKER SWITCH
®
MONEYSAVER SWITCH
(Rocker Switch) (See Figure 8)
This rocker switch can be depressed to either YES or NO. In
the YES position you will get the most economical operation.
Both the fan and the compressor will cycle on and off together,
maintaining the selected temperature at a more constant level
and reducing the humidity more efficiently. This control will
only operate when the unit is in a cooling mode. In the NO
position, the fan will run constantly as long as the unit is in the
cooling mode. Disconnect leads from switch. Depress switch
to function being tested.
1. When YES is depressed, there should be continuity
between terminals "1" and "2."
2. When NO is depressed, there should be continuity
between terminals "2" and "3."
SYSTEM CONTROL SWITCH
("KQ" Models Only) (See Figure 9)
The KQ Model unit uses a five position control switch to regu-
late the operation of the unit. Function of each position (clock-
wise rotation) is as follows:

1. "Off" - Turns everything off.
2. "Hi Fan" - Maximum circulation of filtered room
air (no cooling.)
3. "Low Fan" - Fan runs slower for less circulation
of filtered room air.
4. "Low Cool" - Fan runs slowly for quiet operation
when maximum cooling is not needed.
5. "Hi Cool" - Highest fan speed for maximum cool-
ing.

SYSTEM CONTROL SWITCH - TEST
(See Figure 19)
Turn knob to phase of switch to be tested. There must be
continuity as follows:
1. "Hi Fan" Position - between terminals "L1" and "H".
2. "Low Fan" Position - between terminals "L1" and "L".
3. "Low Cool" Position - between terminals "L1" and "L" and
"C".
4. "Hi Cool" Position - between terminals "L1" and "H" and
"C".
