3. INSTALLATION AND ASSEMBLY

GENERAL
- Our pumps may only be assembled and installed in pools or ponds that are compliant with HD 384.7.702. Should
you have any doubts, please consult your specialist.
- Fit the pump horizontally due to the pre-filter. The pumps are fitted with a pre-filter with a basket inside to collect
any large particles, as they may damage the hydraulic part inside the pump.
- All pumps are fitted with a foot with holes in it to anchor it to the ground (Fig. 1).
PIPING
- To connect the piping, glue the pipes and the connectors, supplied together with the pump; the fitting connections
to the suction and return ports on the pump are threaded and include seals to prevent water loss (Fig. 2).
- Fit the return pipes completely perpendicular and centred in relation to the port to be connected to prevent the pump
and the pipe from being subjected to external stress that, apart from making fitting difficult, could break them (Fig. 2).
- Fit the suction piping on a slight 2% slope towards the pump to avoid the formation of air pockets (Fig. 2).
- To ensure the pump works correctly, prime the pump pre-filter until water rises up through the suction pipe (Fig. 3).
LOCATION
- Fit the pump underneath the water level in the pool to improve pump performance.
- Where a self-priming pump is to be fitted above the water level, the pressure differential to the pump suction should
not be higher than 0.02 MPa (2 mH2O), ensuring that the suction pipe is as short as possible as a longer pipe
would increase suction time and the installation's load losses.
- Make sure that the pump is safe from possible flooding and receives dry ventilation.

ELECTRICAL INSTALLATION

- It is essential that you use a multiple disconnection device with a space of at least 3 mm between surfaces to disconnect
the equipment from the electrical current.
- Use a rigid cable to connect to the mains. If you use a flexible cable to connect to the mains, it must have cable lugs to
connect to the terminals of the pump motor.
- The equipment should be connected to an alternating current supply (see data on the pump's plate) with earth
connection, protected by a residual current device (RCD) having a rated residual operating current not exceeding 30 mA.
- Adjust the value of the thermal relay appropriately depending on the pump current.
- Before connecting the motor, check the type of fuse required.
- Check the correct layout and connection of the earthing cable in the equipment.
- Respect the electrical installation and connection conditions. Failure to do so may lead to the pump manufacturer
declining all responsibility and rendering the guarantee null and void.
- Special regulations may exist for the installation.
- Unsuitable mains connections involve the risk of electrocution.
For pumps with a single-phase motor:
Thermal protection is incorporated.
l
Use a motor guard with magneto-thermal protection.
l
The adjustment data for the thermal relay is to be used as a guideline, as the motor is already fitted with protection.
