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 sup
-
port the weight of the pump and water
filled tank.
2. The pump can also be mounted onto a wall or
the side of an air conditioner 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 interchangeable.
4. Ensure that the pump is level and the inlet is below the coil drain.
Piping Connections
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. 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.
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
Connect the power cord to a constant source of power matching the pump nameplate voltage.
• The pump should be connected or wired to its own circuit, with no other electric receptacles or
equipment 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.
• Connect to a circuit equipped with a ground fault circuit interrupter (GFCI) if required by code.
Some models are supplied with a stripped wire cord end. 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)
IMPORTANT:
If the power cord is damaged, the whole unit must be replaced.
