4. Installation DANGER Disconnect and lock out electrical power before installing or servicing the unit. WARNING Ÿ Do not install the starter equipment in an explosive zone unless it is explosion-proof rated. Ÿ Make sure that the unit cannot roll or fall over and injure people or damage property. WARNING Electrical shock hazard. - Page 17 4.1 Preparation for installation Listed below are tools and instruments that are needed to install the submersible pump for general dewatering purpose: AC voltmeter AC ammeter Insulation resistance tester (megger tester) (tester) (clamp) Wrenches for fastening Wrenches for connecting the power supply bolts and nuts (a screwdriver or a box wrench) Pre-installation check...
- Page 18 3. Handle the pump carefully. When suspending the pump to raise or to lower it, attach a wire rope or a chain to the pump's handle. 4. Install the pump only in an area that can maintain a proper water level. NOTE For details on the water level necessary for pump operation, refer to the section on 'Water Level During Operation"...
- Page 19 CAUTION If an excessive amount of sediment is drawn into the pump, it may cause the pump to wear, which can lead to current leakage or electrical shock. NOTE Appropriate piping materials must be provided by the user. Piping materials are not included with the product.
- Page 20 4.4 Grounding ELECTRICAL HAZARD Ÿ You must ground all electrical equipment. This applies to the pump equipment, the driver and any monitoring equipment. Test the ground lead to verify that it is connected correctly. Ÿ If the motor cable is jerked loose by mistake, the ground conductor should be the last conductor to come loose from its terminal.
- Page 21 CAUTION Ÿ If the cable must be extended, use an extension cable with the same or larger core size as that of the cable that is provided with the pump. Using a cable of proper size will prevent the motor from attaining its full potential or may cause the cable to overheat, which may lead to fire, current leakage or electrical shock.

- Page 24 How to verify the correct pump rotation Ÿ By looking at the impeller. The rotation of the impeller should be counter-clockwise as shown in the figure (1). Ÿ By looking from the top of the pump. Since the impeller cannot be seen, the best way to chek the rotation is to check the kick-back motion of the pump when the pump just starts.
