Maintenance
Warning! Before attempting any maintenance on the unit, dis-
connect the power cord from the power supply to reduce the
risk of electrical shock. Attention: Potential free contact (only
EE400
M
) can still be under poewer).
If the unit does not perform as stated in above tests, remove the tank
cover of the pump (only EE400
M
). The drive unit can be removed
now.
The tank of the EE150 can be removed by inserting a screwdriver in
one of the side slots of the tank and levering it away. (Do not over-
stress the material) After that unscrew the two Phillips screws
located on top. Now verify that the float mechanism moves up and
down freely. If the float binds, it may be dirty or damaged. The motor
itself does not need any maintenance so do not attempt any repairs.
Also never open the drive unit of the EE400
M
because breaking the
seal will invalidate the warranty.
However, the tank and float mechanism will need to be cleaned once
a year. The tank and the floats should be cleaned with mild
detergent using a damp cloth.
Reassemble the unit in reverse order.
Cleaning the check valve and verify its operating
1. After unscrewing the cap nut remove the discharge line from the
check valve
2. Use a SW 20 wrench to remove the check valve from the drive
unit.
3. Visually check the valve for obstructions. If damaged, replace.
4. To re-install the check valve, hands tighten it to the drive unit.
Then, tighten 1/2-turn further with a wrench. Be careful not to
over-tighten as this may distort the O-ring seal under the check
valve.
Replacement items
The discharge nipple with integrated check valve is available for
replacement. It can be used for both pump models.

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:
a) 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 1/2 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.
