20 AMP SWITCH (WD & WH MODELS)
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 Electrical 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 qualified licensed electrician.
FIGURE 4.
FIGURE 5.
Models WD & WH are fully automatic. A float switch is included and factory wired in the pump circuit to provide automatic operation once the float switch is
secured properly to the outlet pipe. Use the diagram above to secure the float switch properly and obtain the proper tether to customize the on-off cycle to each
application. Note the minimum off level shown above. On Prepackaged Systems, the tether length is set at 5”.
Determining Pumping Range
in Inches (1 inch - 2.5 cm)
Tether Length
5 10 15 20 22
Pumping Range
9 13.5 18 22 24
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.
Note:
Failure to keep within proper tether limits may
prevent reliable switch operation.
Note:
Cable must be mounted in horizontal position.
