FILLING
• In the case of installation below water level, fill the pump by slowly opening
the suction gate while keeping the drainage gate open to let the air out.
• In the case of installation above water level, unscrew the knobs and remove
the cover; fill the pump body with water up to the level of the suction inlet
(see figure).
• After starting up, adjust the pump by acting on the discharge gate valve to
check that the pump is working within the range indicated on the nameplate
and that the current absorbed is not exceeded.
• Avoid indoor operations (fully closed discharge gate) for prolonged periods.
SELF-PRIMING
Self-priming is the ability of the pump, when installed above water level, to suck in air from the suction pipe and, after a time
of up to 10 minutes, start pumping water.
Caution: the height from the water level to the pump inlet must not exceed 4 metres.
If the suction height is more than 1.5 m, a non-return valve must be inserted in the suction pipe. In this way, the
suction line will not empty in the event of a stoppage (e.g. for pre-filter cleaning) and the pump restart time will be shorter.
The length of suction pipes should be reduced as much as possible to decrease priming times.
Priming conditions:
• Pump housing filled with cold water up to the suction inlet.
• Non-return valve installed on the suction pipe.
• Suction and drainage gate valves fully open.
• Prefilter not obstructed.
• Suction pipe perfectly sealed and immersed in water.
• Perfect seal of O-rings and mechanical seal of pump.
• Cover knobs and water drain plugs tightened by hand.
• Pressure pipe without non-return valve and with at least 80 cm of straight section after the pressure port (the length of
the straight section can be reduced in the case of low suction heights; to be checked during installation).
If priming has not taken place after 10 minutes (check through the transparent cover), check the above conditions and reset
where necessary.
If the water level drops below the skimmers or other suction nozzles (e.g. when emptying the pool), keep only the gate valve
on the suction pipe open.
SWITCHING OFF
• The product is designed for continuous operation; shutdown can be carried out only by switching off the power supply.
