2.2 Electrical
1. Only qualied electricians are allowed to connect pumps according to local regulations of the power supplier.
2. Grounding of the motor should be applied rst; failure to ground can cause severe or fatal shock. Do not ground to gas
supply lines.
3. Before connecting the motor check corresponding voltage of motor and power supply. Incorrect connection can cause re
or serious damage to the motor and voids warranty. See wiring diagram.
4. Avoid unexpected or accidental starting of the motor by disconnecting and locking out power supply.

10. Do avoid damage to the cord line by not hoisting the pump by the cord line and be sure the cord line is not jammed;
avoid sharp edges.
11. General rule for Hendor pump shaft rotation: Always run clockwise (CW), looking at cooling fan side.

2.3 Checking direction of rotation
Vertical pumps: Always check direction of rotation outside the liquid.
Horizontal pumps: Always check the direction of rotation ooded with liquid.
Briey switching on the power will show direction of rotation, looking at cooling fan side. Ignoring these recommendations will
damage the pump severely.
