IMPORTANT: For 3-phase pumps, check for proper rotation before installing pump into basin. See figure A for proper

rotation.

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)

ALWAYS TURN OFF BREAKERS BEFORE

WORKING ON ELECTRICAL CORDS.

BE CAREFUL NOT TO DRILL OR SCREW INTO

EXISTING WIRING.

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.

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).
