TUBING
• The tubing connection must be screwed to the pump nozzles fig 2).
• Impulsion tube installation is done totally perpendicularly and is well centred with
respect to the nozzle to be connected so as to avoid external pressure being
exerted on the pump and the tube. Apart from making assembly more difficult, this
pressure could even break them. (Fig. 2)
• Suction tube installation is done at a slight angle of 2 % towards the pump, thus
avoided siphon formation. (Fig.2).
• For the pumps correct working, you must prime the pump pre-filter until water dips
into the suction tube (Fig.3).
