Installation Instructions

Mounting the control panel

1. 

  Determine mounting location for panel.  If distance 

exceeds the length of the fl oat switches or pump, 
splicing will be required. 

You must use conduit 

sealant to prevent moisture or gases from enter-
ing the panel.

2. 

  Mount control panel using the mounting fl anges 

furnished with control panel.

3.

   Determine conduit entrance locations on control 

panel.  Check local codes and schematic for the 
number of power circuits required.  

 NOTE:

 Be sure the incoming power, voltage, amper-

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

4.

   Drill proper size holes for type of connectors being 

used.

5.

   Attach cable connectors and/or conduit connectors 

to control panel.

FOR INSTALLATION REQUIRING A SPLICE,

 FOLLOW STEPS 6-10;

FOR INSTALLATION WITHOUT A SPLICE,

 GO TO STEP 11.

6.

   Determine location for mounting junction box(es) 

according to local code requirements.  

7.

   Mount junction box to proper support according to 

local codes.

8.

   Run conduit to junction box(es).  Drill proper size 

holes for the type of conduit used.  

9.

   Identify and label each wire before pulling through 

conduit into control panel and junction box(es). 
Make wire splice connections at junction box(es).

10.

   

Firmly tighten and seal all fi ttings on junction 

box(es).

11.

   

If a junction box is not required, pull cables 

through conduit into control panel.

12.

   

Connect pump wires and fl oat switches to proper 

position on terminals. See schematic inside control 
panel for terminal connections.

NOTE:

 It is the recommendation of the factory to use 

separate pump and control/alarm power sources.

VERIFY CORRECT OPERATION OF CONTROL 

PANEL AFTER INSTALLATION IS COMPLETE.

 

4. 

  Tighten the hose clamp using a screwdriver. Over 

tightening may result in damage to the plastic clamp. 
Make sure the fl oat cable is not allowed to touch 
the excess hose clamp band during operation.

NOTE:

  All hose clamp components are made of 

18-8 stainless steel material. See SJE-Rhombus
