INSTALLATION
NOTE: Do not reduce size of discharge pipe or hose below 1-1/4 in. diameter. If discharge is too small, pump will overheat and fail
prematurely. This pump is designed for use in a residential sump only. Only pump water with this pump.
1. Install the pump in sump pit with minimum diameter of 10 in. for models
equipped with vertical switches and 14 in. for tethered float switch models.
The sump depth should be 14 in. for vertically switched models and 18 in.
for tethered models. Construct the sump pit of tile, concrete, steel or plastic.
Check local codes for approved materials and for proper installation.
2. Install the pump in a pit so that the switch operating mechanism has
maximum possible clearance.
3. The pump should not be installed on clay, earth or sand surfaces. Clean
the sump pit of small stones and gravel which could clog the pump. Keep
the pump inlet screen clear.
NOTE: Do not use ordinary pipe joint compound on plastic pipe. Pipe joint
compound can attack plastics.
4. Install discharge plumbing. Use rigid plastic pipe and wrap threads with
PTFE pipe thread sealant tape. Screw pipe into the pump hand tight plus 1-1/2 turns.
CAUTION: Risk of flooding. Can cause personal injury and/or property damage. If a flexible discharge hose is used, make sure the
pump is secured in the sump to prevent movement. Failure to secure the pump may allow pump movement, switch interference
and prevent the pump from starting or stopping.
5. To reduce motor noise and vibrations, a short length of rubber hose (1-7/8 in. I.D., e.g. radiator hose) can be connected into the
discharge line near the pump using suitable clamps.
6. Install an in-line check valve or an in-pump check valve to prevent flow backwards through the pump when the pump shuts off.
NOTE: If your check valve is not equipped with an air bleed hole to prevent air locking the pump, drill a 1/8 in. hole in the
discharge pipe just above where the discharge pipe screws into the pump discharge. Be sure the hole is below the waterline and
the check valve to prevent air locks.
7. Power Supply: Pump is designed for 115 V, 60 Hz, operation and requires a minimum 15 amp individual branch circuit.
Plug the pump power cord plug into the piggyback switch plug outlet, and then plug the switch plug into a 115V GFCI power
outlet for automatic operation. The pump will start operating if the float switch moves over the pump top. The water will be
pumped out. When the water lowers to certain level, the float switch will turns off the pump.
