drain pan. Repeat until the pump runs 2–3 times.
Check for any water leaks, kinked or pinched lines, or siphoning action.
Clicking noises heard at initial start-up are normal and are usually only heard for the first
few operations.
Allow a one minute rest after each cycle to prevent triggering the thermal protector.

to an appropriate drain.
Note: Make sure connection hoses are not clogged, kinked, or twisted. Use anti-kink
spring on tubing as needed [
12].
10. Verify the power source voltage matches the pump’s voltage requirement. Connect the
pump power supply cable [
3] to a constant source of power (not a fan or other device that
runs intermittently).
Note: Do NOT connect or link the air conditioner’s power cable directly to the power
supply cable of the pump [
3].
11. When preceding steps are complete, verify the unit and connections by performing a TEST
OPERATION [next page].
