INSTALLATION
Physical Installation
1.
Install the pump on a flat surface.
•
Make sure the mounting surface will support the combined weight of the pump and water filled
tank.
•
The air vent openings around the motor housing must not be blocked or obstructed to allow the
free flow of air.
•
Ensure that the pump is level and the inlet is below the coil drain.
2. The pump can also be mounted on a wall or the side of an air conditioner or furnace. The tank has two
mounting slots, one located at each end of the tank.
Piping Connections
Connect inlet and outlet tubing as follows:
1.
Cut end of pipe(s) from evaporator or furnace drain at a
45° angle as shown to prevent pipe(s) from sealing
closed when sitting against the tank’s floor.
2. Route drain pipe downward into pump inlet opening.
3. Install outlet 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.
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.
