Operation of Drain Switch

Condensate Pump (Drain Pump)

condensate pump, which collects the water that

forms on the evaporator during normal cooling

operation and eliminates 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.

When the water level drops below level (B), the

drain pump will stop.

NOTE:

• If for any reason the water level exceeds that of

level (A) in the pump reservoir, an overflow

Drain Switch will stop the compressor opera-

tion.

• If the Fan Mode Control DIP Switch (see pg.17) has been set from the COOL to the STOP position,

the Fan will also turn off while the drain

pump is discharging water.

7. Drain Switch (If drain tank is equipped)

The Office Pro 60 is equipped with a drain tank switch. When the drain tank accumulates approximately 4.0

gallons (15 liters) of condensate (water) in the drain tank, the drain tank switch sends a signal to the micro-

processor. The microprocessor stops all operation of the unit and flashes the “Tank Full” LED.

This system utilizes a 0.1 AMP, 250 VAC micro-switch for this function. When drain water accumulates

approximately 4.0 gallons (15 liters) in the drain tank, the drain tank base plate, which is supported at its

fulcrum, is pushed down in the arrow direction as shown in the figure below. When the drain tank base

plate is forced down, the top of the drain tank base plate turns off the contacts (1) – (2) of the micro switch.
