DRAINAGE TEST FOR UNITS WITHOUT A
CONDENSATE LIFT PUMP

Check that the drainpipe is unhindered. Fill the drain pan with 0.5
gallons (2 liter) of water.

CONDENSATE LIFT PUMP AND DRAINAGE TEST

Follow these steps to perform the test:

1. Remove the test cover by rotating it counter−clockwise as

shown in Fig. 27.

2. Using a piece of tubing or pipe, fill the condensate lift pump

reservoir with 70 oz. of water (see Fig. 28).

3. Turn the unit ON in cooling mode. The condensate lift

pump comes on. Watch the end of the drain pipe for any
water. It may take some time for the water to travel,
depending on the length of the drain pipe.

4. During this test, check all bends or joints for leakage.
