2.2 I Hydraulic connecti ons
• Respect the directi on of hydraulic connecti on (see § "1.3 I Dimensions and marking").
•
Choose the piping size according to the pool size and in compliance with the hydraulic rules applicable in the country
of installati on.
•
Performance curves are available in § "1.4 I Performance curves" for the pipe dimensions.
•
For hydraulic connecti ons, bond the Ø63/50 mm union couplings (provided) or use the 2’’ threaded PVC couplings
directly screwed onto the pump.
•
Fit a check valve if the pump is installed above the water level.
•
Fit sucti on and discharge isolati on valves if the pump is installed below the water level.
•
To help prevent diffi culty in priming, install the sucti on pipe without high points, which can trap air
•
Check that the hydraulic correcti ons are correctly ti ghtened and that there are no leaks.
•
The pipes must be supported to prevent any risk of breakage due to the weight of the water.

•
Use as few elbow joints as possible. If more than 10 elbow joints are to be installed on the hydraulic circuit, increase
the pipe diameter.
•
Sucti on pipe length = 4 x Ø
•
Sucti on pipe too short
•
Risk of cavitati on
•
Air retenti on
•
Risk of incorrect pre-fi lter fi lling
