Thank you for purchasing this Clarke Submersible Pump. These highly efficient pumps are designed for pumping clean water, or water containing sand or solids in suspension, (please see Features, page 5), and are ideally suited for draining ponds, pools, building excavations etc., where water temperature does not exceed 50°C. These pumps are NOT suitable for pumping salt water, or for permanent installation in fish ponds as the acidity, found in fish ponds, will damage the pump seals.
ELECTRICAL CONNECTIONS All models should have their mains lead connected to a standard 230Volt (50Hz) electrical supply through an approved plug or a suitably fused isolator switch. We recommend that these pumps be fitted with a Residual Current Device (RCD). NOTE: This is mandatory when pump is used for pumping swimming pools and ponds If the pump is to be connected to an outdoor electrical supply, make sure that both the plug and the socket are of a BS approved waterproof design.
FEATURES These pumps are of rugged and durable construction, designed for long lasting continuous operation and their stainless steel bodies provide good anti corrosive properties. The motor is provided with built in overload protection. For your information the charts, on pages 9 and 10, show the flow rate for each pump at various heads. (HEAD is the distance, or height, from the surface of the water to the point of discharge) These pumps are designed to pump water containing solids in suspension.
It should not normally be necessary to change the length of cable (from the clamp to the float switch), but should you do so, remember that the cable length should NEVER be so long that the float switch fails to operate and switch the pump OFF. ALWAYS check its operation before use. INSTALLATION All pumps are complete with an Outlet Hose Adapter which simply screws into the outlet port on top of the pump body. Model CS85 is provided with a 1”BSP threaded adapter which will accept a 1” I.D. hose.
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. Check the pump installation regularly to ensure the base inlet is clear of leaves or other debris. Note that these pumps are fitted with automatic thermal overload protection. If the pump overheats due to an obstruction in the pump, or pumping warm water in excess of 50oC for example, it will shut off automatically.
TROUBLE SHOOTING A. PUMP WILL NOT START 1. Manual type (i.e. without float switch) 1.1 Check to ensure Power is switched on. 1.2 Check fuse (consult an electrician if in doubt). 1.3 If extension lead is fitted, check connections (consult an electrician if in doubt). 1.4 Internal thermal cutout has not reset.
