6 CP-Series Submersible Motors Installation, Operation and Maintenance Manual
Handling and Installation (continued)
IV. Handling and Installation
(continued)
Before installing the motor, read this instruction manual and the one supplied with the pump
or electric pump to which the motor will be coupled. Keep both manuals in a safe place for
future reference.
Selecting the electrical panel
Make sure the panel power ratings match those of the pump. Incompatible combinations
may cause faults and fail to fully protect the motor.
Before installing, carefully read the instructions supplied with the electrical panel.
Checking the motor liquid level
Place the motor in the vertical position, with the air valve facing upwards. Unscrew the air
valve from its hole. Add clean water using a syringe, until the water overflows the hole. Make
sure the valve is not clogged. If necessary, clean it or replace it. Screw the valve back into the hole.
Installation in a well or tank
When installing the electric pump vertically, make sure the motor does not rest on the bottom of the
well or tank.
When installing the electric pump horizontally, make sure the motor does not rest on the bottom of the tank.
Electrical connections to the electric motor
Make sure that the supply voltage and frequency are compatible with the electrical panel. The
relative information is shown on the motor rating plate and in the documents supplied with
the panel. Provide suitable short circuit protection on the supply line.
Before proceeding, make sure that all the connections (even if they are potential-free) are
voltage-free. Unless otherwise specified in local bylaws, the supply line must be fitted with:
• a short circuit protection device
• a high sensitivity residual current circuit breaker (30mA) for additional protection from
electrocution in case of inefficient grounding.
• a disconnect switch with a contact aperture of at least 3 mm.
Ground the system in compliance with current regulations. Attach the included lead wire to the upper endbell.
