This control panel must be installed and serviced by a licensed
electrician in accordance with the National Electric Code NFPA-70, state
and local electrical codes.
All conduit running from the sump or tank to the control panel must be
sealed with conduit sealant to prevent moisture or gases from entering the panel.
NEMA 4X enclosures are for indoor or outdoor use,
primarily to provide
a degree of protection against corrosion, windblown dust and rain, splashing
water and hose-directed water.
Cable connectors must be liquid-tight in
NEMA 4X enclosures.
Most Type 123 panels are designed to operate as three or four float systems.
The three float system is standard performing the common pump stop, lead
pump start, and lag pump start/high level alarm functions. The four float system
utilizes separate floats for lag pump start and high level alarm.
NOTE: Options ordered may affect the number of floats and their func
-
tions. Please reference the schematic provided with the control panel
for proper installation.
Installation of Floats
CAUTION:
If control switch cables are not wired and mounted in the correct
location, the pump system will not function properly.
WARNING:
Turn off all power before installing floats in pump chamber. Failure
to do so could result in serious or fatal electrical shock.
1.
Use float label kit to identify and label cables on both float and stripped
ends (stop, lead, lag, alarm, etc.). See schematic for float options.
2.
Determine your normal operating level, as illustrated in
Figures 1-2
.
3.
Mount float switches at appropriate levels as illustrated in
Figures 3-5
.
Be
sure that floats have free range of motion without touching each other, or
other equipment in the basin.
If using the mounting clamp; follow steps 4-6.
4.
Place the cord into the clamp as shown in
Figure 5
.
5.
Locate the clamp at the desired activation level and secure the clamp to
the discharge pipe as shown in
Figure 5
.
NOTE:
Do not install cord under hose clamp.
6.
Tighten the hose clamp using a screwdriver. Over tightening may result in
damage to the plastic clamp. Make sure the float 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 your SJE-Rhombus
®
supplier for replacements.
