5.2.4 Protective conduit and hose for air regulator
Lay and fasten the protective conduit and the hose for the air
regulator above the water level.
5.2.5 Pipe sizing
Suction lines which are too long have significant disadvantages:
•
Higher resistance, therefore poorer flow characteristics and a
higher risk of cavitation.
5.2.6 Laying pipes
NOTICE
The main housing and the screw connections are made of ABS. A
curing time of at least 12 hours for the bonding
must be observed!
 Keep the suction and pressure lines as short and straight as
possible.
 If possible, lay the suction and pressure lines below the water
level.
 Install a shut-off valve in both the suction and pressure lines.
 Avoid valves which close suddenly or, if present, close them
slowly.
 If the pump is positioned further away, the pipe dimensioning
has to be adapted so that an almost loss-free flow is
ensured.
 Use elbows instead of angles.
 At a distance of between 5 m and 10 m:
– At 45 m³/h: Suction line d125/Pressure line d125
– At 58 m³/h: Suction line d140/Pressure line d140
– At 75 m³/h: Suction line d160/Pressure line d140
5.2.7 Pump shaft
Store the pump unit in a shaft adjacent to the pool. The
installation room must have proper aeration and ventilation and a
sufficient ground drain. A connection for equipotential bonding has
to exist in the pump shaft. See "Installation example: standard
version" on page 30.
 Please observe the pipe dimensions.
