AFTER THE PUMP IS INSTALLED, THE ELECTRICAL CHECKS OF SECTION 4 MUST BE PERFORMED.
4-1 PIGGY BACK SWITCH OPERATION
1. Plug the Piggyback switch into a 6-20R receptacle. The receptacle must be
wired to a 30-amp breaker. Be sure to have the breaker turned off before
plugging in the switch.
2. Plug the pump power cord into the piggyback switch as shown.
3. The pump is ready to test and your breaker can be turned on.
(Refer to section 5)
4-2 DIRECT WIRING OF AUTOMATIC PUMP
The pump can run on a voltage rating of
230V or 208V. Check that it is the same as
the supply voltage. The pumps are
supplied with 6-20P (20-amp) cord plug
ends. If a single phase pump is to be wired
directly into a control device or junction box,
and it is necessary to remove the plugs,
have a certified electrician do the wiring in
accordance with the National Electric Code
and applicable local codes. See Fig. B for
direct wire installation of single phase,
automatic pumps.

1. The control panel is preferably mounted
in a cool, dry environment. Installation
and connections are specific to the
control panel. Control panels should be
installed and serviced only by a
qualified electrician (Refer to Figure 2, page 10).
Check three phase pumps for proper
rotation prior to installing pump(s) in
basin. To change rotation, reverse any
two of the three power leads to the
pump. Code the wires for reconnection
after installation.
Check to make sure installation is in accordance
with the National Electric Code and all applicable local codes. Installation and servicing is to be
conducted by qualified personnel. This pump is supplied with a grounding conductor. To reduce
the risk of electrical shock, be certain that it is connected to a properly grounded earth wire.
