DRAIN SYSTEM TEST
Procedure for Testing Drain System
(both gravity and drain pump models)
Drain pump models have a safety feature that will interrupt power to the unit if a high-limit condition occurs to prevent
flooding. This safety feature can be initiated by a restriction in the drain system and will continue until high-limit condition
is corrected, at which time power will be restored to the unit. Power interruption can be detected when no icons are
visible in the display area of the user interface (Figure 12). Once power is returned, a startup chime will sound followed
by a self-test, and "OFF" should be visible in the display area.
On/off

Once the drain line is plumbed, perform the following:
1. Plug the ice machine into 115v power supply.
2. Place unit in the final installation location.
3. Turn the unit off via the user interface (display will indicate "OFF"). The drain pump will still be operational during off
mode if the unit has one.
4. Slowly pour 3-qts of water into the ice storage bin. All water should drain completely.
5. If water drains fully and without power interruption, the drain system has been successfully tested and further
installation of the ice machine can be continued.
6. If the water does not drain or a power interrupt occurs, check the following:
a. There are no kinks or restrictions in the drain line. (Note: Drain line needs to be cut to the required length and any
excess tubing should be removed to prevent possible restrictions).
b. Your drain line is plumbed into an open drain (Figure 13).
c. The vent tube on the back of the unit is open (Figure 14).

7. After checking the above requirements, repeat step 4 and verify the water drains completely without power
interruption. If problems persist call a qualified service technician and/or plumber.
