Other Checks; Maintenance And Cleaning - Saci CF-2 Manual De Instalación Y Mantenimiento

12. CHECKS PREVIOUS TO STARTING
Before starting the electro-pump, make sure that:
• The pump is properly stoked (that the pump body and pre-filter are completely full). The reason for this is that
the pump should immediately begin to work correctly and the sealing mechanism (mechanical) should be well
lubricated. Dry working causes irreparable damage to the mechanical closure.
• Make sure that the mains voltage and frequency correspond to those indicated on the characteristics plate of
the pump.
• It is a good rule to make sure that the pump and/or motor shaft move freely. To do this, move the couplings
that join the motor shafts by hand, once the cover is removed. Once this check is complete, replace the covers
in their original positions.

Other checks

• The auxiliary circuits are properly connected.
• The electrical connection has been carried out as indicated previously.
• The alignment between the pump and the motor has been performed correctly.
• Before starting new installations, all valves, pipes, tanks and connections must be carefully cleaned.
13. STARTING
Open the pump uptake and drive flood valves completely.
Make sure that the motor is turning in the right direction (looking from the rear of the motor, the fan
must turn, CLOCKWISE). If it turns in the wrong direction, two phases of the protection circuit supply
must be inverted. After isolating the pump from the electricity supply.
When the hydraulic circuit is completely full of liquid, progressively open the drive flood valve until it is
fully open. It is necessary to check the power consumption of the motor in the ideal working place and compare it with
the figure on the characteristics plate, and suitably adjust the protection thermal relay.
While the electro-pump is working, check the supply voltage of the motor junctions, which should not differ by more than
+/- 5 % from the nominal value.

14. MAINTENANCE AND CLEANING

The electro-pump may only be dismantled by specialised, qualified personnel in possession of the requirements
demanded by the corresponding standards. In any case, all repair and maintenance work will only be undertaken
after disconnecting the pump from the mains supply. Make sure that it can not be turned on accidentally.
Only for swimming pools
The main maintenance operation that must be scrupulously watched over is the cleaning of the pre-filter basket,
which must be undertaken following every filtering operation and especially after cleaning through the silt
cleaner. The steps to be followed are:
Turn off the electricity supply to the pump. Close the pump uptake and drive stop valves. Open the pre-filter cover,
take out the basket and clean without knocking. Once clean, refit and before closing, check the state of the pre-
filter cover and seal. Clean thoroughly with water only and, if necessary, lubricate lightly with neutral Vaseline.
After a long time working, it will be somewhat difficult to dismantle the parts in contact with water. To do so, use
any product commercially available and, if necessary, a suitable extractor.
Do not force the various parts with unsuitable tools.
Under no circumstances must we place the chlorine tablets in the pump pre-filter basket.
