Putting Into Service - EBARA SWS Série Manuel D'installation Et D'entretien

9. CHECKS PRIOR TO PUTTING INTO SERVICE
THE PUMP SHOULD NEVER BE ALLOWED TO OPERATE OFF LOAD
Check that the voltage and frequency of the incoming mains electricity supply correspond to those on the pump's
specification plate.
Unscrew the transparent pre-filter cover and fill the pre-filter with water until the water level reaches the suction hole.
Replace the pre-filter cover and hand-tighten only, ensuring that it is fully tightened.
Check the pump shaft is able to freely rotate.
Check the that the direction of motor rotation corresponds with that indicated on the
specification plate (the fan should rotate in a CLOCKWISE DIRECTION, when viewed from
the rear of the motor. If the motor is three-phase and it is observed that it is rotating in
the opposite direction, then two of the supply phases should be inverted at the protection
panel.

10. PUTTING INTO SERVICE

Open all valves, both suction and impulsion, and switch on the pump.
Wait a reasonable time for the pump and suction piping to self-prime. If this takes too long, then the priming
process should be repeated.
Once the pump has correctly self-primed and the pre-filter body is seen to be full of water, the motor current should
be checked and the thermal relay adjusted appropriately.
11. MAINTENANCE, DISMANTLING AND RECYCLING
The most important maintenance operation is that of keeping the pre-filter basket clean, and this filter state
check should be performed after each filtration operation and especially after bottom-cleaning. The procedure
is as follows:
Disconnect the electricity supply to the pump. Close the suction and impulsion valves to the pump. Open the pre-filter
cover, remove the basket and clean it. Once it is clean, replace it, but before closing, check the condition of the pump
body thread, pre-filter cover and the O-ring, cleaning them only with water, and where necessary apply a light coating
of neutral Vaseline.
The pump should only be dismantled by qualified personnel who hold the technical qualifications required under the
technical safety regulations of the country where the product is located.
This product and its components must be disposed of in accordance with environmental regulations. Use local public
or private waste-collection systems.
