INSTALLATION
Physical Installation
1.
Install the pump on a flat surface
•
Install the enclosed rubber feet onto the bottom of the tank.
•
Make sure the mounting surface will support the combined
weight of the pump and water filled tank.
2. The pump can also be mounted onto a wall or the side of an air condi
-
tioner or furnace, using the enclosed mounting bracket. The tank has a
mounting slot on each side so it can be positioned either way.
3. Pumps with an anti-sweat sleeve use a different bracket, but the
mounting location holes are the same and the brackets are inter
-
changeable.
4. Ensure that the pump is level and the inlet is below the coil drain.
Piping Connections
Connect inlet and outlet tubing as follows:
1.
Cut end of pipe(s) from evaporator or fur
-
nace drain at a 45° angle as shown to pre
-
vent pipe(s) from sealing closed when
sitting against the tank’s floor.
2. The pump will accept up to three drain lines.
However, take care to make sure that total
inflow does not exceed the rated output of
the pump to prevent overflow. Route drain
pipe(s) downward into one or more pump
inlet openings one to three inches, ensuring
no interference with float operation. Keep any unused openings closed using the supplied cap plugs.
3. Install outlet tubing or piping onto outlet check valve and secure with hose clamp (not provided).
•
Use 3/8” inside diameter maximum tubing or piping to prevent excessive flow back to unit.
•
Check to ensure that the check valve is securely locked into position.
4. Route outlet tubing or piping from pump straight up as high as necessary.
•
Do not extend higher than 75% of the total dynamic head capacity of the pump.
5. From the high point, slope discharge line down slightly to a point above the drain area. Then, turn down
and route to a suitable drain at a point below or approximately level with the bottom of the pump, if
possible. This will produce a siphoning effect which will improve efficiency of the pump.
6. If it is not possible to slope the discharge line down, make an inverted “U” trap directly above the pump
at the highest point.
Electrical Connections
The power cord must be connected to a constant source of power matching the voltage specified on the
pump nameplate.
•
The pump should be connected or wired to its own circuit, with no other electric receptacles or equip
-
ment in the circuit. Do not connect to a fan or any device that runs intermittently.
•
The fuses or circuit breaker should be of ample capacity in the electrical circuit.
•
Connect to a circuit equipped with a ground fault circuit interrupter (GFCI) device if required by code.
Some models are supplied with a stripped wire cord end. Power connections must be made within a junc
-
tion box, and must comply with the National Electrical Code. Wires are color coded as follows:
•
Green/yellow = Ground; Brown = Line; Blue = Line (230 V) or Neutral (115 V)
IMPORTANT:
The power cord cannot be replaced. In case of damage, the whole unit must be replaced.
