2. INTRODUCTION & SPECIFICATION
3.1. GENERAL CARE INSTRUCTIONS
3.1.1. Keep the pump clean and well maintained.
3.1.2. DO NOT use the pump if any part of it is damaged. Have it inspected by your local Sealey dealer.
3.1.3. DO NOT run the pump dry. Make sure that the pump is already filled or ready to be filled with water, before use.
3.1.4. DO NOT overtighten the filler plugs as this will damage its threads.
3.1.5 Make sure the pump securely anchored, through the holes in its feet, in a horizontal position.
3.1.6. The pump is designed to pump water only, DO NOT use it to pump flammable or corrosive liquids.
3.1.7. Make sure that a strainer is always connected to the inlet hose to prevent debris from being drawn up and into the pump causing damage.
3.2. PREPARATION FOR USE
 WARNING! DO NOT connect the pump to the mains electrical supply until all hose installation is completed.
3.2.1. Connect a male inlet connector into the pump and hand tighten (fig.1). Ensure that the direction of flow arrow is pointing to the pump.
3.2.2. Screw a non return valve to the inlet filter, make sure it is correctly orientated, with the spring loaded valve able to pass water into the filter. Make sure the
bowl of the filter is hanging down. (Sealey recommend Water Pump Filters part no. WPF1 or part no. WPF2 for use with these pumps).
DO NOT over tighten any of the connections.
3.2.3. Positioning the pump (Refer to fig.1)
• check hoses for damage, they must be protected and supported as they are considerably heavier when filled with water.
• the pump must always be operated in a horizontal position with the outlet port pointing vertically upwards.
• use the fixing holes in the feet to anchor the pump in its operating position.
• make sure there is good air circulation around the pump motor.
• the pump must not become soaked with water, neither the motor or the terminal box are waterproof.
• place the pump as close to the water source as possible.
• Make sure there is adequate drainage for the water that is discharged.
3.2.4. Pipe connections:
• use as large a diameter inlet pipe as practical, otherwise the performance of the pump will be affected.
• a gate valve may be positioned on the outlet side of the pump. This can be used to regulate the flow of water, and be useful in priming the pump.
 WARNING! DO NOT place any restriction on the inlet side of the pump, unless it is an isolator valve in a gravity fed system. The pump should not be used
with the delivery valve closed.
• if the pump is to be permanently fixed the fittings to the pump must be flexible. Short pieces of hose should be fitted to form the join to any rigid pipes.
• ensure there are no air leaks as this will prevent effective priming and affect the pump's capacity.
• make sure all pipes are kept as short and straight as possible.
• hoses laid across roadways need to be protected by planks to reduce "hydraulic shock" caused by vehicles running over them.

3.2.5. Foot Valve/Filter
If the pump is used to draw raw water from a well or excavation a foot valve/coarse filter should be fitted to the lower end of the suction hose, (see fig.2).
This will retain water in the suction system and prevent large objects entering the pump body. It may be necessary to keep the foot valve clean by:
• constructing a bed of stones to rest the foot valve on.
• position the valve to clear of the bottom of the pit, pond etc.
• securing the foot valve inside a basket or bucket.
3.2.6. Preparing the Booster Pressure Tank
An air pressure tank and regulator provide a constant water pressure at the outlet. The pump automatically cuts in when the water pressure reaches a
preset value. The regulator is pre-set at the factory and must not be altered.The following proceedure must be completed before connecting to the water
supply.
• For the system to work correctly the tank must be pressurised to its rated operating pressure of between1.8 bar (26psi) and 2.0 bar (29psi).
• Unscrew the cap on the end of the tank to reveal the air valve (see fig.2).
• Use an air line or foot pump to pressurise the tank.
• check the pressure using a standard pressure gauge, replace the cap when finished.
3.2.7. Priming the Pump
It is essential that all connections and hoses are completely tight for the system to work.
This is a self priming pump but the inlet side of the pump still needs to be completely filled with water before initial starting or if the system has been drained
for any other reason.
• remove filler plug (fig.3) and slowly fill with water until all the air is expelled.
Note: Refilling is necessary if the pump has been drained or if the water has been lost. DO NOT allow the pump to run dry.
• open all valves on the outlet side of the pump to achieve as great a flow as possible.
