Mounting the Control Panel

1.

Determine mounting location for panel. If distance exceeds
the length of either the float switch cables or the pump power
cables, splicing will be required. For outdoor or wet instal-
lation, we recommend the use of a liquid-tight junction box
with liquid-tight connectors to make required connections.

You must use conduit sealant to prevent moisture or
gases from entering the panel.

2.

Mount control panel with mounting devices furnished.

3.

Determine conduit entrance locations on control panel.

NOTE:

 Be sure the incoming power, voltage, amperage,

and phase meet the requirements of the pump motor being
installed. If in doubt, see the pump identification plate for
electrical requirements.

4.

Drill proper size holes for type of connectors being used.

NOTE:

 If using conduit, be sure that it is of adequate size

to pull the pump and switch cables through.

5.

Attach cable connectors and/or conduit connectors to con-
trol panel.

FOR INSTALLATION REQUIRING

A SPLICE, FOLLOW STEPS 6-9;

FOR INSTALLATION WITHOUT A SPLICE,

GO TO STEP 10.

Installation Instructions

6.

Determine location for mounting junction box according to
state and local code requirements. Mount junction box to
proper support.

7.

Run conduit to junction box. Drill proper size holes for the
type of conduit used. Attach connectors to junction box.

8.

Identify and label each wire before pulling through conduit
into control panel and junction box. Make wire splice con-
nections at junction box.

9.

Firmly tighten all fittings on junction box.

10.

  If a junction box is not required, pull cables through conduit

into control panel.

11.

Set motor protective switch:
a) set the dial to match motor full load amps
b) turn dial on motor protective switch to the ON position

NOTE:

 Resetting the dial with power applied to the motor

protective switch could start the motor.

12.

  Connect pump wires directly to the motor contactor terminal

positions T1, T2, and T3.

NOTE:

 Three phase motors will run in either direction. Check

pump motor before installation for proper rotation. To cor-
rect rotation, change pump cable connections on any two
terminals T1-T2-T3.

13.

  Connect “power-in” conductors to proper locations: 208/

240/480 on 3 position terminal block. 

Install tagged fac-

tory wire to appropriate transformer primary voltage tap.
