OPERATION (cont.)
Drain Pump Kit (Optional)
(Office Pro 12 model ONLY)
A drain pump kit (CPK-3) is available to allow continuous operation and
to eliminate the need for a drain tank.
• When the water collects to level
(A) in the pump reservoir, the
drain pump begins to operate
and discharges the water.
A
B
NOTE: The compressor will not
operate while the drain pump is discharging water.
• When the water level drops below level (B), the drain pump stops,
and the compressor will restart.
NOTE: If for any reason the water level exceeds that of level (A) in
the pump reservoir, an overflow Drain Switch will stop the compres-
sor operation.
NOTE: If the Fan Mode Control DIP Switch (see pg. 13) is set to the
STOP position, the entire unit (including fan operation) will turn off
whether due to the overflow Drain Switch or while the drain pump
is discharging water.
