Espa FILTERKIT BASE Manual De Instrucciones página 10

If the equipment is below the water level, a gate
valve must be fitted to the pump intake and
discharge.
The surface on which the filter is fitted must be
horizontal and completely flat.
It must be fitted in a permanent location and,
whenever possible, below the water level of the
swimming pool.
The maximum admissible pressure is 2,5bar (36
Psi); to avoid overpressure in the use of the
equipment, it must not be fitted at a depth of more
than 4m below the water level of the swimming pool
or connected to the public water mains.
The room or hut where the filter is located must
have a drain, in order to avoid the risk of flooding
that would affect the safety of the electrics and of
persons.
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. 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.
3.4. 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
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.
