Troubleshooting
CLEANING THE CHECK VALVE
1. Unplug the condensate pump.
2. Remove the discharge line from the check valve.
3. Use a 9/16" wrench to remove the check valve from
the pump deck.
4. Inspect the valve for obstructions or damage. Clean or
replace it as needed.
5. Thread the valve back into the pump discharge by
hand, plus 1/2 turn with the wrench.
NOTICE: Don't overtighten the valve, as overtightening
can distort the O-Ring that seals the valve, causing
leaks.
6. Plug in the pump, fill the reservoir, and run the pump
through one complete pump-down cycle to be sure it
works correctly.
7. The pump is ready for operation.
TROUBLESHOOTING
Pump does not run
• Check power to furnace/AC and to pump circuit. Be
sure pump is plugged in.
• Condensate level in reservoir may not be high enough
to start pump. (Water must be 2" below the top of the
reservoir for pump to start.)
• Dirt or algae clogging reservoir.
• Inlet line clogged.
• Stuck float resulting from dirty reservoir.
• Make sure that float switch is not stuck in the down
(off) position.
For parts or assistance, call Flotec Customer Service at
Pump runs, no discharge
• Make sure the discharge tubing (especially the end of
the tubing) is not plugged.
• UNPLUG pump and make sure check valve and
impeller discharge port are not plugged.
• Make sure the float switch is not stuck in the on (up)
position.
PREVENTIVE MAINTENANCE
Unplug the pump and clean out the reservoir at the begin-
ning and end of each heating season. Use a commercial
algaecide and follow manufacturer's instructions.
Putting about a gallon of algaecide solution in the reservoir
and then cycling the pump several times will keep the
reservoir and the discharge line free of algae build-up.
Be sure to dump the cleaner and rinse the reservoir with
water before starting the pump.
Be sure you do not clog the impeller discharge port or the
check valve when starting the pump after cleaning.
Whenever you replace the motor cover and screws, be
sure that the motor cover catches the float switch pivot pin
and does not pinch either the power cord or the safety
switch leads. Do not over-tighten the screws.
SERVICING A DOUBLE-INSULATED
APPLIANCE
A double insulated product uses two layers of insulation
(one inside the other) to provide protection from electrical
shock hazards. No separate grounding wire is required.
DO NOT try to install a grounding wire on a double-
insulated device.
Only qualified service personnel should attempt to service
a double-insulated product, because safe servicing requires
extreme care and knowledge of the system. Any replace-
ment parts installed in a double-insulated product must be
identical to the original parts that they replaced.
A double insulated product is marked with the words
"DOUBLE INSULATION" or "DOUBLE INSULATED".
