INSTALLATION
1. Place pump in a location
convenient to the appliance drain
line.
2. Pump may be mounted level to
ensure proper operation. Attach
directly to air conditioning unit,
furnace, wall, or placed on the
floor. Use the provided template
for locating screw .
3. For ease of installation, the pump
reservoir can be easily removed
from the pump. The pump lid can
then be rotated 180 degrees to
orient the location of the cord and
discharge line to opposite ends.
4. Connect the condensate drain into
one of the four top inlets, using
flexible tubing or PVC pipe; OR
hard plumb directly into the
bottom of the pump using the
optional bottom inlet.
5. Make sure that the inlet tubing is
fastened securely so that it cannot
come out of the pump intake port.
6. Connect discharge tubing to the pump, run tubing from pump to desired
drain location. Pump discharge check valve is made for use with 3/8” ID
plastic tubing.
7. Press tubing on discharge check valve and clamp tight with a ½” hose clamp.
8. Run tubing to necessary height, making sure that the height does not
exceed the pumps maximum lift (15’KTP-15, 19’ KTP-20).
9. From maximum height slope tubing slightly downwards and/or make an
inverted “U” trap at the highest point, creating a siphon to maximize pump
performance. (Figure 1)
10. Condensate can be drained out a window, along the air conditioner freon
line to outdoors, to a french drain or floor drain, sump pit, or to a laundry tub
or sink. (Leave an air gap between the end of the discharge tube and drain).
11. Comply with all local codes for discharge water requirements.
Optional Bottom Inlet Instructions:
(This step is for convenience only) (Figure 3)
Place the pump on a flat surface. Use a flat screw driver to knock out additional ports as
needed. There are three other inlet ports on the lid and one on the lower side. The bottom
inlet needs to be hard plumbed. This is done by applying PVC cement to the bottom inlet an
inserting ¾” PVC piping.
CONNECTION OF AUXILIARY SAFETY SWITCH
—MODELS
KTP-15X, KTP-20X are equipped with an auxiliary safety
switch which can be wired to shut down the AC/furnace
and prevent pump overflow if the drain line becomes
blocked, or the pump fail. The switch can also be wired as
an alarm switch for installations that do not allow
interruption of heating or cooling.
To Wire as a Shut-off switch:
(Figure 4)
1. Disconnect power to the AC/furnace and unplug condensate pump before connecting the safety switch.
2. Disconnect the “Red” wire from the AC/furnace bundle coming from the thermostat.
3. Connect the red wire to one of the two yellow wire leads coming off the condensate pump, using a wire nut.
4. Connect the other yellow wire lead from the condensate pump to the red terminal on the AC/Furnace block.
5. If additional wire is needed to connect the pump to the thermostat line, use minimum 18AWG copper wire, rated at
105 degrees C. Comply with all local wiring codes.
Hose Clamp
3/8" ID Tubing
To Floor Drain
or Laundry Tub.
Ceiling and Joists
Grounded
Outlet
Discharge tube should
slope down toward
outlet if possible
Do not kink tube !
Cut tubing at an angle
so that bottom of
reservoir doesn't close it.
Be sure tubing does not
interfere with float.
