Pump test
1. Remove the inlet tubing from the pump.
2. Pour water into the inlet until the pump turns on.

“pump-out” is complete.
4. Reconnect the inlet tubing to the pump.
Operation
After proper installation, the operation of the Uniflair condensate pump is automatic.
Troubleshooting
Under most circumstances, the pump requires little maintenance for efficient operation. If a problem occurs,
check the following items or call Schneider-Electrical Technical Support.
The following guidelines can help to return the pump to service.
• Check inlet and outlet piping for blockage or kinks that inhibits flow.
• Make sure the floats move freely.
• Make sure the pump impeller casing is not clogged
• Make sure the check valve is not clogged.
Pump Does Not Run
• Check to see that the power to the system (Uniflair unit) is on to allow production of condensate.
• Check that the pump is plugged in and the circuit is active (fuse or breaker not blown).
• Check the level of water in the reservoir. The level must be within 50.8 mm (2 in.) of the reservoir top to
activate the switch. The inlet tube may be blocked and require cleaning if no water is entering the
reservoir.
• If there is a proper amount of water in the reservoir, the float may be stuck due to dirt or algae formation.
Flush the reservoir with warm water and a mild soap or detergent.
