INSTALLATION
Physical Installation
• 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
1. Cut end of pipe(s) from evaporator
or furnace drain at a 45° angle to
prevent pipe(s) from sealing closed
against the tank's floor.
2. Route drain pipe downward into
pump inlet opening.
• To open one of the closed inlets,
insert a screw driver into the slot
and twist to remove. Be sure the
knockout plug does not fall into
the tank.
3. Install outlet tubing or piping onto outlet check valve.
NOTE: When verifying installation, keep in mind a click will be heard when the check valve is
securely locked.
• With the factory installed 3/8" hose barb, use 3/8" inside diameter maximum tubing or piping to
prevent excessive backflow to unit and secure with cable-tie (not provided).
• Ensure the outlet tube/check valve adapter is locked into place by verifying the adapter is
rotated clockwise as far as possible and the tab on the adapter is aligned with the closed lock
symbol.
4. Route outlet tubing straight up, not exceeding 75% of total dynamic head capacity of the pump.
5. At the top, make an inverted "U" trap directly above the pump at the highest point.
6. 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.
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.
IMPORTANT: If the power cord is damaged, the whole unit must be replaced.
