2.2 HYDRAULIC PIPING
• Observe the direction of the hydraulic connections.
• Select the pipe size according to the size of the pool in line with the hydraulic standards in place in
the country of installation.
• For hydraulic connections, use the standard connections required.
• Fit a check valve if the filter is installed above the water level.
• Fit isolation valves (suction and discharge) if the pump is installed below the water level.
• To avoid problems with priming, install the suction pipe so that there are no high points where air
can build up.
• Check that the hydraulic connections are securely tightened and that there are no leaks.
• The piping should be well supported to avoid any risk of breakage due to the weight of the water.

• Use as few elbow joints as possible. If there must be more than 10 elbow joints in the hydraulic
circuit, the diameter of the piping must be increased.
