Installation And Assembly; Electric Installation - Astralpool VIRON P300 Manual De Instalación Y Mantenimiento

Check the temperature of the machine and the electrical motor. In the event of a fault,
stop the machine immediately and repair.
Check for machine vibrations. In the event of a fault, stop the machine immediately and
repair.
Due to the complex nature of the cases treated, the installation, user and maintenance instructions
contained in this manual do not seek to examine all possible and imaginable cases of service and
maintenance. Should your require additional instruction or have specific problems, please do not
hesitate to contact the distributor or the machine manufacturer directly.

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 two 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 difference in height
must be no more than 2 metres (Fig. 4), ensuring that the suction pipe is as short as
possible as a long pipe would increase drainage times and load losses in the installation.
Make sure that the pump is safe from possible flooding and receives dry ventilation.

ELECTRIC INSTALLATION

The electric installation must include a multiple separation system with contact
openings of at least 3 mm.
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.
With any type of pump, 0.03 A differential protection must be fitted for electricity
leakage protection (indicated on the diagrams).
Adjust the value of the thermal relay appropriately depending on the pump current.
For pumps with a single phase motor:
Thermal protection is incorporated. Installation with a switch is sufficient, in line with
the "Main connections" diagram.
Use a motor guard with magneto thermal protection.
The adjustment data for the thermal relay is to be used as a guideline, as the motor is
already fitted with protection.
