Vent Plumbing
Vent Plumbing
The vent is essential for proper switch operation and must not be omitted or restricted. The basin must
be vented in accordance with state and local codes.
1. Plumb vent to fitting in basin cover using 2-inch threaded pipe.
2. Hand tighten plastic fittings.
3. Use pipe joint compound.
NOTE: A 2" MNPT x 1½" slip pipe adapter is provided if a 1½-inch vent is required.
IMPORTANT: Do not use a mechanical vent with this product as it will cause improper operation of the
automatic switch.
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.
• 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.
• Under no circumstances should outlet box or receptacle be located where it may become flooded or
submerged by water.
• If installed in basement, plug connection should be four feet or more above floor, especially if base-
ment floods.
Some pumps are supplied with a 3-prong electrical plug. The third prong is to ground the pump to pre-
vent possible electrical shock.
• Plug into a grounded receptacle with vent tube pointed down.
• Vent tube must remain unobstructed for proper pump operation.
• Secure power cord to piping with ties or tape.
IMPORTANT: Do not cut plug from the cord. If the plug is cut or the cord is shortened, then the war-
ranty will be void.
IMPORTANT: If the power cord is damaged, the whole unit must be replaced.
Operation Testing
1. Fill unit with water through inlet.
2. Verify that the pump starts when the water reaches 7 – 10 inches (17.8 cm – 25.4 cm).
3. Verify that the pump stops when the water reaches 2 – 5 inches (5.1 cm – 12.7 cm).
