It is recommended that around the filter there
should be sufficient space in order that the
inspections, checks and maintenance required may
be carried out.
PVC accessories must be used for the connections
between the piping and the selector valve, pump,
etc.
The connections must be made watertight by
means of seals and it is not necessary to tighten
screws excessively or use teflon.
The pipes in the installation must be made of PVC.
Under no circumstances should iron accessories or
pipes be used, since these could seriously damage
the plastic components of the installation.
Do not load the sand until the initial start-up has
been performed.
3.3. How to assemble the filtering kits
The steps to follow for assembling the filtering kits
are:
– Attach the sand container to the base using the
two screws supplied.
(Fig.12)
– Attach the pump to the base using the four
screws supplied in the indicated order.
(Fig.13)
– Add the sand (see point 3.4 in the manual).
– Install the selecting valve and the pressure
gauge.
– In order to assemble the flexible connection kit,
first connect the PUMP exit-point of the valve and
then bend the flexible tube so as to screw the
connecting thread into the exit-point of the pump.
(Fig.14)
3.4. Loading of sand
The sand loaded must correspond to the grading
and quantity indicated on the filter specifications
plate. Load the sand as indicated below:
(Fig.8)
1. Check that the pump is not in operation.
2. Set the selector valve to the “CLOSED” position.
3. Remove the selector valve and fit the funnel as
shown to prevent sand from entering the collector
unit.
4. Pour water into the vessel until the tank is 1/3
full, followed by the sand. Take care not to damage
the collector arms.
5. Fit the valve to the vessel and the pump once
again: The area of the watertight seal between the
valve and the vessel must be clean and free of
sand.
Take care not to damage the collector arms.
Avoid pouring sand inside the central pipe.
3.5. Start-up
1. Cleaning: Clean the swimming pool as well as
possible before starting up the filtration unit.
Remove dirt and foreign bodies from the skimmer
siphon and pump prefilter.
2. Priming the suction: Open the pump prefilter
cover and completely fill with water up to the level
of the suction intake.
(Fig.9)
Close the cover and check that it is correctly fitted.
3. Filtration start-up: Set the selector valve to the
“Filtration” position. Turn the equipment on.
4. Bleeding: Remove the air from the inside of the
pump, valve and deposit. Slightly open the bleeders
available.
(Fig.10)
Close the pump filter cover and bleeders correctly,
so that they are watertight.
5. Adjust the hours of operation of the equipment in
accordance with the volume of the swimming pool,
the flow supplied by the pump and it’s situation.
See Table 1.
After the initial start-up it is recommended to keep
the filter running continuously for 24 hours and then
to clean the remains of dirt on the pump prefilter
and skimmers.
4. WINTER CARE
In winter the filtering installation must be protected
from the risk of frost.
(Fig.11)
If the equipment is not going to be used during the
winter period, the following operations must be
performed:
– Wash the filter in accordance with the
instructions.
– Disconnect the equipment from the mains.
– Completely empty all the water from the filter,
pump and pipes.
– Set the key on the filter to the “WINTER” position.
Once the winter period is over, proceed according
to the instructions for the initial start-up.
