4 Installation Site Specifications / Installation
4.1 Planning the pump pit
When planning a pump pit take into account:
1. Clear dimensions min. 600 x 600 x 600
2. Return connection min. 300 mm under the pool water level.
3. Leakage water discharge pipe-end min. DN 40
4. Opening for cooling air min. 2x DN 125
5. Be sure to cover the pump pit if it is installed in the open air.
6. The position of the non-return air valve (L) must always be over the pool water level .
7. In case of leakage from the pump, a suitable water drainage must be provided!
Warning! Mortal danger!
If the motor is to be installed with a metal supporting foot, then it must be fa-
stened insulated against the floor to avoid the transfer of spurious voltages to
the device and swimming pool water.
Warning! Risk of damage!
As the pumps are not self-priming, the installation must be under water level.
Make sure you take this into account during the installation planning phase.
