Pump
Installation
Pipe connection is made BEFORE electrical installation.
Placing (see figure 1).
WARNING
• Place the pump on a lower level than the pool water surface and close to the pool to have
as short suction pipe as possible.
• Clearance space behind the pump should be at least 2.5×motor fan diameter.
• Fix the pump with appropriate bolts on a solid foundation in a dry place.
Make sure that this place has sufficient ventilation and with no risk for flooding.
• Pumps with pre-filter should be placed in such a way that the strainer basket in the
prefilter easily can be lifted out for cleaning.
Pipe installation
Dimension pipelines
according to the table below.
Suction pipe
In order to optimise the pump, the following rules shall be followed when planning and dimensioning the suction pipe: large pipe
dimension, short suction pipe, few valves, few sharp pipe curves, low-positioned pump and well-sealed pipe seams to avoid air
leakage. If any of these rules is not followed, the pump's lifetime may be shortened. Aim for an entirely straight suction pipe
closest to the pump, of a length that corresponds to at least 8×pipe diameter.
Dimension the suction pipe as per the table below. Gravity from pool to pump is recommended. The suction pipe should be fitted
with a shut-off value that should always remain entirely open when the pump is in operation.
If the pump is positioned higher than the pool's water surface, a non-return value should be fitted to the suction pipe. However,
this contributes to flow losses and the pump should be somewhat restricted with the help of a valve on the pressure side. If this
is not done, there is a risk of pump cavitation, which can lead to shaft seal leakage and damage to the pump impeller.
Check that all the connections are entirely sealed and leak-proof. (Use thread sealing tape to ensure a proper seal in screw
threads).
Pressure pipe
Connect the pressure pipe of the pump to the filter.
Avoid sharp bends. Check that the connections are tight. Use thread tape when sealing the threads.
