•
Connect the switch leads in series with the low voltage external component as specified in the
component’s manual.
Place the “Attention Service Technician” label included with the pump on the outside of the access panel
in a visible location.
Operation Testing
To test system operation, follow these steps:
1.
Turn on power to the pump.
2. Test pump operating switch by pressing lightly on the
external test/run lever to start the motor.
3. Test high level switch by raising high level switch float.
•
If wired to NO terminal, air handling device should
shut down when float is raised.
•
If wired to NC terminal, external component (alarm or
relay) should activate when float is raised.
MAINTENANCE
To inspect and clean the tank and other components, follow these steps:
1.
Disconnect the pump from the power source.
2. Remove the ¼ turn check valve. Inspect the check valve
and clean with warm water and mild soap if necessary.
3. Remove tank assembly from the pump by squeezing the
reservoir at places indicated to release the latch.
•
Place a finger in one of the larger holes in the corner of
the top and lift to remove the top part of the pump.
The top hinges on the opposite end of the tank.
4. Be sure the floats move freely. Clean as necessary.
5. Clean the tank with warm water and mild soap.
6. Flush tank with fresh water. This helps to ensure that resid
-
ual condensate does not create localized pockets of acid
that could cause pitting.
7. Check inlet and outlet piping. Clean as necessary. Be sure
there are no kinks in the line that would inhibit flow.
8. Replace the tank assembly to the pump.
9. Replace inlet and outlet piping.
•
Fully insert the check valve into the discharge line, ensuring that the O-ring and
discharge line are free of debris.
•
Insert the check valve into the pump discharge hole and twist it by hand ¼ turn.
•
Check to ensure that the check valve is securely locked into position.
10. Test operation of the system.
Risk of bodily injury or property damage.
•
Do not allow the tank to overflow during this maintenance.
•
Inspect and test the condensate removal system condition and operation every 6 months (more fre
-
quently in heavy-use applications).
