Installation For Proper Pump Operation
The pump must be secured in a manner that prevents the pump from moving. If the pump is allowed to move, the float switch could be
restricted by the sump wall, preventing the pump from turning on or off. The minimum diameter sump hole should be no less than 14"
(356 mm) for a tethered float and 10" (254 mm) for a vertical float. The minimum depth should be no less than 18" (457 mm) for tethered
models and 14" (356mm)for vertically switched models. The tether length should be no shorter than 3" (76 mm) for proper operation.
DO NOT increase the tether length on the float switch to more than a 5" (127 mm) tether or pump will not turn OFF.
To allow the unit to deliver maximum capacity, the sump should be kept free of accumulated sediment. A 1¼" (32 mm) discharge pipe will
give the best performance for this pump. The vertical distance from the pump to the highest point of discharge piping should not exceed
20 feet for best performance. Keep trash or other objects from interfering with the float.
Pump And Piping
The pump and piping should be positioned securely so that the float will not hang up on the side of the sump, the power cord or the
discharge pipe. The discharge pipe should be 1¼" (32 mm). A union should be installed to facilitate installation and a check valve is
recommended to prevent water from draining back into the sump and increasing pump operating frequency. The discharge pipe should
be routed to the point of disposal with a minimum number of elbows to reduce losses.
A rigid discharge pipe is recommended to prevent the pump from moving. If a flexible discharge hose is used, the pump must be secured
in a manner that prevents the pump from moving. If the pump is allowed to move, the float switch could be restricted by the sump wall,
preventing the pump from turning on or off.
Pump Operation
The pump will start when the water has filled the sump to a depth that engages the automatic float switch. The pump will stop when the
water depth disengages the automatic float switch. The pump will recycle thereafter as required. Allow pump to go through several cycles
to assure satisfactory operation. If pump does not operate properly, see Trouble Shooting Checklist.
Refer to Figure 1 for recommended typical installation.
Electrical Information
WARNING: Risk of electrical shock - this pump is supplied with a grounding type attachment plug. To reduce the risk of
electrical shock, be certain that it is connected only to a properly grounded type receptacle.
The pump operates on a 115 volt, 60 cycle AC, single phase and has three-prong electric plug. The third prong is used to ground the
pump to prevent possible fatal shocks. The third prong must not be removed. The fuse or circuit breaker used should be a 15 amp time-
delay type.
Automatic Thermal Overload Protection
The motor has a built-in automatic overload protector. It will cut off the power to the motor before the temperature rises enough to
damage the motor windings. Should the overload stop the pump operation, it will reset automatically. Operation will resume when the
motor cools enough to close the overload switch.
