- Page 27 Electrical wiring work All electrical work must be performed by an authorised electrician in compliance with local electrical equipment standards and internal wiring codes. Improper wiring can lead to current leakage, electrical shock, or fire. Provide a dedicated earth leakage circuit breaker, single phase preventer, dry run preventer and overload preventer for the submersible pump.
- Page 28 Do not use damaged cables, power plugs, or loose power outlets. Failure to observe this precaution could lead to electrical shock, short circuit or fire Caution Precautions during installation When installing the pump, be mindful of the pump’s centre of gravity and weight. If the pump is not suspended properly, the pump may fall and break, which may lead to injury Warning...
- Page 29 If a hose is used, route it as straight as possible. Excessive bending of hose could obstruct flow of water, reduce pumping volume, or clog the pump with sludge, thus disabling the pumping function Operate the pump upright. If there is likelihood of the pump drawing in excess mud / sludge, raise the pump by placing a concrete block under the pump If the pump draws in large amounts of mud, it could cause pump to wear prematurely and lead to malfunction, current leakage, and electrical shock.
