INSTALLATION

GENERAL INFORMATION

Installation must be carried out in ventilated, weather-protected areas, with the pump axes in hori-
zontal position and the base facing downwards. Installation in areas with potentially explosive atmos-
phere is strictly forbidden.
• Provide sufficient space around the pump to ensure ventilation of the motor, to check the free rotation of the motor with
a screwdriver and the direction of rotation (three-phase only), to remove the pre-filter, to fill and empty the pump casing.
• In the case of fixed pools, the electric pump must be installed at least 3 m from the pool edge.
• When used as a portable pump, adequate protection must be provided, and the pump must be installed on an insulating
support of at least 100 mm.

PIPES

• Size the piping so that liquid velocity is lower than 1.5 m/s at intake and 3 m/s at drainage.
• Make sure that all pipes are clean before connecting them. Particles of sand or dirt bigger than about 1mm can cause
premature wear and performance degradation.
• Isolate the pump by closing the upstream and downstream shut-off valves when testing the pipes for leaks at pressure
higher than 2.5 bar.
• Use plastic pipes and fittings.
• Avoid excessive tightening (just ensure sealing) and anchor the pipes on their own supports to avoid weight and vibra-
tions on the pump.
• Avoid the use of shut-off valves with non-adjustable closure to limit water hammer blows. The installation of dampers in
the pipes is recommended to prevent water hammering on the (plastic) structure of the pump.
Suction pipes
• Suction pipes must be perfectly sealed to avoid air from entering the system. In the case of installation below water level,
a gate valve must be fitted to both the suction and discharge lines - as close to the pump as possible - to isolate the pump
from the system.
