FOR YOUR PROTECTION, ALWAYS DISCONNECT THE PUMP FROM ITS POWER SOURCE BEFORE HANDLING.
Single phase automatic 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 wired and grounded in accordance with the National Electri-
cal Code and all applicable local codes and ordinances.
“Risk of electrical shock”
Do not remove the power supply cord and strain relief or connect conduit directly to pump.
Pump Wiring Instructions
Installation and checking of electrical circuits and hardware should be performed by a quali
fi
ed licensed electrician.

Models WD & WH are fully automatic. A
fl
oat switch is in clud ed and fac to ry wired in the pump circuit to provide automatic operation once the
fl
oat switch is
secured prop er ly to the outlet pipe. Use the di a gram above to secure the
fl
oat switch properly and obtain the proper tether to cus tom ize the on-off cycle to each
application. Note the minimum off level shown above. On Prepackaged Systems, the tether length is set at 5”.

Use only as a guide. Due to weight of
ca ble, pump ing range above hor i zon tal
is not equal to pumping range be low
hor i zon tal. Ranges are based on test ing in
nonturbulent con di tions. Range may vary
due to water tem per a ture and cord shape.
As teth er length in creas es, so does the
vari ance of the pump ing range.
Note:
Failure to keep within proper teth er limits may
pre vent reliable switch op er a tion.
Note:
Cable must be mounted in hor i zon tal position.
