condensate and preventing flooding), but it will not allow
the furnace/AC unit to restart until the condensate pump
reservoir is emptied. It should be monitored so that in
case of high water in the reservoir, corrective action can
be taken before freezing/overheating occurs.
NOTICE When installing the pump in a new home or after
a renovation project, be sure that debris in the duct work
does not get into the reservoir; it will clog the system.
2. Safety Switch Sounds Alarm
A. Make sure the pump is unplugged.
B. Remove the two screws holding the motor cover to
the pump deck. Remove the cover.
C. Do not disturb the two yellow wires going through the
deck and into the motor (they are potted into the top of
the motor so there are no wire ends visible) .
D. Remove the white wire from the bottom terminal
(NC or Normally Closed) on the end of the safety
switch and reattach it to the upper terminal (NO or
Normally Open) on the end of the switch.
E. Run the white switch wires out through the notch in
the motor cover and replace the motor cover. Make
sure all wires (power cord and safety switch) run
through the notch. Hook the cover under the catch
on the deck and secure it with two screws.
F. Connect the white wires from the safety switch to the
alarm of your choice (purchase separately). Consult
the alarm manufacturer’s instructions for correct
connections to the alarm.
G. Plug in the pump.
H.
Risk of flooding . Can cause personal
injury and/or property damage. With installation
No. 2 (“Safety Switch Sounds Alarm”), the alarm
is activated when the water level in the reservoir
is within about 1/2” of the top of the reservoir.
However, the furnace/AC unit will continue to
produce condensate because the alarm will not shut
it down. Monitor the installation so that in case of
high water level in the condensate reservoir you
can take action before the reservoir overflows and
flooding occurs.
Testing Auxiliary Safety Switch:
NOTICE Some appliances may not start immediately due
to a built-in delay circuit that prevents rapid cycling of
the compressor.
1. Start appliance.
2. Unplug the condensate pump so that it cannot pump
out.
3. Pour water into the pump reservoir until it is almost
full.
4. As the water rises in the reservoir, the safety switch
should shut down the appliance or set off the alarm
(depending on the installation procedure used).
5. Plug in the condensate pump and allow it to empty
the reservoir. As the water level goes down in the
reservoir, the safety switch should reset, allowing the
appliance to start or shutting off the alarm.
Maintenance
1. Disconnect the power to the furnace/AC unit and
unplug the pump.
2. Disconnect the tubing to the pump. Drain the tubing
into a container.
3. Remove the two mounting screws and remove the
pump from the furnace or wall. Dump the reservoir
into a floor drain or container.
4. After you have dumped the pump, remove the four
screws securing the reservoir to the pump deck. Lift
the deck/pump assembly off of the reservoir.
5. Turn the deck/pump assembly upside down and
remove the five screws holding the impeller cover to
the motor.
6. Remove the impeller cover. The rotor/ impeller
assembly may come out with it. If not, pull it out of
the rotor chamber in the motor. (You may have to
pull it hard to get it out against the magnetism in the
motor windings.)
7. Clean the impeller, rotor, rotor cavity, and O-Ring.
Use a rag to clean the O-Ring groove in the impeller
cover and the sealing surface on the bottom of the
motor block.
8. Clean out the reservoir.
9. Reassemble the impeller and the impeller cover;
tighten the screws carefully. Do not overtighten!
10. Turn everything right side up and reassemble the
reservoir to the deck. Be sure the impeller cover
fits into the molded ring in the bottom of the
reservoir. Fasten the reservoir with the four screws at
the corners.
11. Reinstall the pump on the furnace.
12. Plug in the pump, fill the reservoir, and run the
pump through one complete pump-down cycle to be
sure it works correctly.
13. The pump is ready for operation.
