(please see Pump Features, page 5).
SAFETY PRECAUTIONS 1. This pump is designed to pump WATER ONLY. Never use for pumping flammable liquids or chemicals of any kind. 2. NEVER allow the pump to run dry. 3. An approved Residual Current Device (RCD) MUST be used when pumping from ponds or swimming pools. 4. Your submersible pump may ONLY be used for pumping water from a swimming pool when there is no person or animal in the pool. 5.
ELECTRICAL CONNECTIONS The mains lead should be connected to a standard 230Volt (50Hz) electrical supply through an approved 13Amp BS 1363 plug or a suitably fused isolator switch. We recommend that the pump be connected via a Residual Current Device (RCD). IMPORTANT: If used for draining swimming pools or ponds, it is mandatory that the pump be fitted with a Residual Current Device (RCD), with a rated residual operating current of no greater 30mA.
If the power cable becomes damaged, IT MUST BE REPLACED, DO NOT REPAIR. Return the pump to your Clarke dealer, or contact Clarke Service Department on: 020 8988 7400 IMPORTANT: If you are in any doubt regarding electrical installation, you should consult a qualified electrician. DO NOT attempt any electrical repairs yourself. PUMP FEATURES The pump is of rugged and durable construction, designed for long lasting continuous operation and its’ stainless steel body provides good anticorrosive properties.
INSTALLATION The pumps’ delivery outlet is provided with a 2” BSP female thread, for connection to a suitable adapter (not provided). It is advisable to seal the thread with PTFE, or similar tape, to ensure maximum performance from your pump. The delivery hose used should be of the same ID as the delivery outlet and completely sound. Any holes, no matter how small, will reduce the efficiency of the pump, or even prevent the pump from delivering water at all.
MAINTENANCE WARNING Before checking the condition of the pump, ensure it is unplugged from the mains supply. If the unit is hard wired, ensure the circuit breaker is open. The pump should require no maintenance other than regular cleaning. Its’ mechanical seal is lubricated in an oil chamber, and its’ bearings are ‘sealed for life’. If the pump starts to show signs of wear or damage, contact your CLARKE dealer for advice.
