WD & WH MODEL INSTALLATION
WIRING DIAGRAM FOR MODELS
WD - 230V, 1 Ph, 60 Hz.
WH - 200/208V, 1 Ph, 60 Hz.
Models WD & WH are fully automatic. A oat switch is included and
factory wired in the pump circuit to provide automatic operation
once the oat switch is secured properly to the outlet pipe. Use the
diagram above to secure the oat switch properly and obtain the
proper tether to customize the on-off cycle to each application.

in Inches (1 inch - 2.5 cm)
Tether Length 5 10 15 20 22
Pumping Range 9 13.5 18 22 24
max.
Use only as a guide. Due to weight of
cable, pumping range above horizontal
is not equal to pumping range below
horizontal. Ranges are based on testing in
nonturbulent conditions. Range may vary
due to water temperature and cord shape.
As tether length increases, so does the
variance of the pumping range.

THREE PHASE WIRING INSTRUCTIONS
FOR YOUR PROTECTION, ALWAYS
DISCONNECT PUMP FROM ITS POWER SOURCE
BEFORE HANDLING.
To automatically operate a nonautomatic three phase pump, a
control panel is required. Follow the instructions provided with the
panel to wire the system. For automatic three phase pumps see
automatic 3 phase wiring diagram located to the far right.
Before installing a pump, check the pump rotation to ensure that
wiring has been connected properly to power source, and that
the green lead of power cord (See wiring diagram), is connected
to a valid ground. Momentarily energize the pump, observing the
directions of kick back due to starting torque. Rotation is correct if
kick back is in the opposite direction of rotation arrow on the pump
casing. If rotation is not correct, switching of any two power leads
other than ground, should provide the proper rotation.
All three phase pumps require motor starting devices with motor
overload protection. See FM0486 for duplex installations. Pumps
must be installed in accordance with the National Electrical Code
and all applicable local codes and ordinances. Pumps are not to
be installed in locations classied as hazardous in accordance
with National Electrical Code, ANSI/NFPA 70.

SINGLE PHASE WIRING INSTRUCTIONS
FOR YOUR PROTECTION, ALWAYS DISCONNECT PUMP FROM ITS POWER SOURCE BEFORE HANDLING. Single phase
pumps are supplied with a 3-prong grounded plug to help protect you against the possibility of electrical shock. DO NOT UNDER ANY CIRCUMSTANCES
REMOVE THE GROUND PIN. The 3-prong plug must be inserted into a mating 3-prong grounded receptacle. If the installation does not have such
a receptacle, it must be changed to the proper type, wired and grounded in accordance with the National Electrical Code and all applicable local codes
and ordinances.
“Risk of electrical shock” Do not remove power supply cord and strain relief or connect conduit directly to the pump.
Installation and checking of electrical circuits and hardware should be performed by a qualied licensed electrician.
Units supplied without a plug (single and three phase) and single phase nonautomatic units with a 20 amp plug must have a motor
control and liquid level control provided at time of installation. The control device should have suitable voltage, ampere, frequency, grounding and
horsepower rating for the pump to which it is connected.
