This control panel must be installed and serviced by a licensed electri-
cian 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
1 enclosures are for indoor use only, primarily to provide a degree of protection
against contact with enclosed equipment. Cable connectors are not required to be
liquid-tight in NEMA 1 enclosures. Do not use NEMA 1 enclosures if subjected
to rain, splashing water or hose-directed water. NEMA 4X enclosures are for
indoor or outdoor use, primarily to provide a degree of protection against corro-
sion, windblown dust and rain, splashing water and hose-directed water. Cable
connectors must be liquid-tight in NEMA 4X enclosures.
Most Type 122 panels are designed to operate as three or four fl oat systems. The
three fl oat system is standard performing the common pump stop, lead pump start,
and lag pump start/high level alarm functions. The four fl oat system utilizes separate
fl oats for lag pump start and high level alarm.
NOTE: Options ordered may affect the number of fl oats and their functions.
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 fl oats in pump chamber. Failure to
do so could result in serious or fatal electrical shock.
1. Use fl oat label kit to identify and label cables on both fl oat and stripped ends
(stop, lead, lag, alarm, etc.). See schematic for fl oat options.
2. Determine your normal operating level, as illustrated in Figures 1-2.
3. Mount fl oat switches at appropriate levels as illustrated in Figures 3-5. Be
sure that fl oats 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 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.
