ELECTRICAL CORD CONNECTIONS
SWITCH CORD - The cord assembly mounted to
the switch must NOT be modified in any way. Any
modifications to the switch cord will void the warranty.
OVER-TEMPERATURE PROTECTION - The type of in-
line over-temperature protector used in this level control
is referred to as an inherent overheating protector
and operates on the affect of temperature rise. This
means that the over-temperature protector will trip out
and shut the pump off if the switch becomes too hot. It
will then automatically reset after the switch cools to a
safe temperature. In the event of an over-temperature,
the source of this condition should be determined and
rectified immediately.
DO NOT LET THE PUMP CYCLE OR RUN IF AN
OVER-TEMPERATURE CONDITION OCCURS!
CORD CONNECTION - Insert female end of cord plug
into housing bore aligning, alignment mark with detent in
terminal block, See Figure 14.
Tighten bolts until the corners of the compression flange
are drawn down to the top of the level control.
DO NOT OVER TORQUE.
INSTALLATION INSTRUCTIONS:
SENSAPRO LEVEL CONTROL FOR ECOTRAN
AND UPGRADE CORE PUMP STATIONS
Step 1: REMOVING EXISTING LEVEL CONTROL
Remove ESPS Switch assembly from basin.
Step 2: REMOVING EXISTING LEVEL CONTROL
POWER CABLE
Disconnect level control power cable from ESPS
Switch by removing two retaining screws and
lock washers.
Step 3: INSPECTING EXISTING LEVEL CONTROL
POWER CABLE
Inspect level control power cable for damage on
the cord jacket or pin connection areas. Replace
level control power cable if damage is found.
Step 4: ATTACH LEVEL CONTROL POWER CABLE
Insert female end of cord plug into housing bore
aligning, alignment mark with detent in terminal
block, See Figure 14. Install the two retaining
screws and lock washers. Tighten bolts until the
corners of the compression flange are drawn
down to the top of the level control.
DO NOT
OVER TORQUE
Step 5: INSTALLING THE MECHANICAL LEVEL
CONTROL
The mechanical level control has a unique
shape. This will fit into the pocket shaped to
accept it in the POD next to the pump. Lower
the mechanical level control into the pocket
which will automatically set the correct height off
the basin bottom.
DO NOT DROP
TYPICAL INSTALLATION COMMENTS:
1. Never work in sump with power on.
2. Level Controls are factory set for the necessary
pumping differential.
3. One cycle of operation should be observed, so that
any potential problems can be corrected.
IMPORTANT NOTE: Do not use the Level Control
in gasoline, volatiles, or other combustibles.
