INSTALLATION
Physical Installation
Risk of damage to pump or other equipment.
•
There is a plastic plug inserted in the inlet opening beneath the conduit connector. Do not remove
this plug and do not use this inlet opening.
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.
Piping Connections
Connect inlet and outlet tubing as follows:
1.
Cut end of pipe from evaporator drain at a 45° angle as
shown to prevent pipe from sealing closed when sitting
against the tank's floor.
2. Route drain pipe downward into pump inlet opening.
•
For plenum applications, use metal tubing such as
copper, from evaporator.
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.
•
For plenum applications, use metal tubing such as copper.
•
Replace plastic check valve with brass check valve, Part Number 599063 (purchased separately).
NOTE: Thread sealant must be used when using the brass check valve.
4. Route outlet 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 pump has individual power conductors for making a hardwire connection to the power supply. It does
not have a power cord or electrical plug. The power conductors 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.
Power connections must be made within a junction 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)
