Installation
Check local codes for discharge water requirements. Run
the discharge line to a point outside the house if possible.
To do this easily, you may be able to run the condensate
discharge line out through the wall along the AC freon line.
Use the existing line if possible (when replacing an existing
pump).
Clamping the plastic discharge line to the check valve with
a 1/2" hose clamp (purchase separately) will help to keep it
in place, especially with older tubing (plastic tubing tends
to harden as it gets older).
Common locations for the end of the discharge line are:
A. Out a window or along the air conditioner freon line to
the outdoors.
B. To a floor drain (leave an air gap between the end of
the tube and the drain).
C. To a laundry tub or sink (leave an air gap above the tub
drain).
Plug pump into a 115-volt outlet
that carries power that will not be
interrupted. Do not connect pump to
a fan or limit control circuit or the like.

Hazardous voltage. Plug pump into a
115-volt outlet. Pump is double insulated; grounding
is not required.
With the unit plugged in and the discharge line installed,
fill the pump reservoir until the pump starts. Allow it to
pump down and shut itself off automatically to verify prop-
er operation through one complete cycle.

Safety Switch:

Most models include an automatic safety switch which
should be wired to activate an alarm or to cut off power in
the event of high water in the condensate reservoir.
If you must run additional wire from the low voltage safety
switch to the alarm or to the control wiring of your fur-
nace/AC unit, use at least 18 gauge (AWG) copper wire
rated at 105° C. Make connections with wire nuts as
shown.
If your installation allows interruption of heating or cooling,
follow procedure 1, below.
If your installation does not allow interruption of heating or
cooling, follow procedure 2, "Safety Switch Sounds Alarm".
Risk of electrical shock. Disconnect power
to furnace/AC unit and be sure condensate pump is
unplugged before starting procedure.
For parts or assistance, call Flotec Customer Service at
Some Models include an
auxiliary safety switch.
Connect switch as
explained in "Safety Switch".

1. Safety Switch Shuts Down Furnace/AC
A. Make sure the pump is unplugged.
B. Find the red wire in the bundle from the thermostat
and disconnect it from the furnace/AC unit.
C. Connect the red wire to one of the white wires from
the safety switch as shown in Figure 1.
D. Connect the other white wire from the switch to the
furnace/AC terminal strip where the red wire from
the thermostat was connected.
E. Plug in the pump.
F. The furnace/AC will now operate as long as the
condensate pump empties the reservoir. If the reser-
voir overfills, the switch will open and cut off the
power to the furnace/AC.

Risk of freezing/overheating. This installa-
tion will shut down the furnace/AC unit if the water level in
the pump reservoir rises to within about 1/2" from the top
of the reservoir (thereby stopping the production of con-
densate and preventing flooding), but it will not allow the
furnace/AC unit to restart until the condensate pump reser-
voir 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.
