troubleshooting
If the pump does not function properly, refer to the following:
1. Unit does not run:
a) Check the power supply
b) Check the appliance to see if condensation is actually being generated
c) Check to make sure the pump float mechanism moves freely and clicks
the activation switch when moved up and down.
d) Check the drain line(s) into the pump for obstructions.
Note: If these lines are clogged and remain clogged, the appliance may
eventually be damaged.
2. Pump makes loud noise when running:
Check the tank for debris and clean if necessary. Refer to the maintenance
section for cleaning instructions.
3. Unit runs but does not pump liquid out:
a) Check the floats to be sure that they are not stuck in the up position.
b) Check the height of the discharge tubing to be sure it does not exceed
the allowed head (see specifications)
c) Check the discharge tube for obstructions and clear if needed.
d) Check the check valve for obstructions. Refer to the maintenance
section for cleaning instructions.
4. Liquid drains back into pump from discharge line:
a) Check valve may have debris in it. Refer to the maintenance section for
cleaning instructions
b) If the discharge line is plumbed so the highest point is less than 1 m
above the pump, the check valve may allow liquid to drain out of the
line. This is normal and will not damage the pump.
5. Liquid leaks from around the check valve:
a) Check the proper fit of the cap nut that holds the discharge tube in
place.
b) If the check valve is too tight or too loose it may leak around the O-ring.
Check that the valve is hand tight, and then tighten an addition ½ turn
with a wrench.
c) If the O-ring under the check valve is damaged, replace with a new one
or purchase a replacement check valve, which includes an O-ring.
