MAINTENANCE
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 frequently in heavy-use applica-
tions).
To inspect and clean the tank and other components, follow these steps:
1. Disconnect the pump from the power source.
2. Remove tank cover assembly from the tank.
• The cover snaps on to the reservoir.
• Pull out on the slot on the long side of the top. Place a finger in one of the larger corner holes
and carefully lift off the cover. Hold level.
3. Be sure the floats move freely. Clean as necessary.
4. Remove the check valve and backwash the discharge port into the volute over a sink.
5. Clean the tank with warm water and mild soap.
6. Flush tank with fresh water to ensure that residual 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 that would inhibit flow.
8. Inspect the check valve and clean with warm water and mild soap if necessary.
9. Replace the tank cover assembly.
