INSTRUCTION MANUAL
– If the equipment is below the water level, a gate
valve must be fitted to the pump intake and dis-
charge.
– The surface on which the filter is fitted must be hori-
zontal and completely flat.
– It must be fitted in a permanent location and, whe-
never possible, below the water level of the swim-
ming pool.
– The maximum admissible pressure is 2 bar (29
Psi); to avoid overpressure in the use of the equip-
ment, it must not be fitted at a depth of more than 4
m 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 inspec-
tions, 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:
(TP Models) (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 packer as
shown.
4. Pour water into the vessel until the tank is 1/3 full,
followed by the weight of sand indicated on the
specifications plate label. 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.
(LT Models) (Fig. 9)
1. Check that the pump is not in operation.
2. Set the selector valve to the "CLOSED" position.
3. Remove the filter cover, taking care not to damage
the seal or the pressure gauge.
4. Remove any dirt or foreign bodies from the inside.
5. Check that the collectors are in good condition.
6. Pour water inside the vessel until the tank is 1/3
full, followed by the weight of sand indicated on the
specifications plate label.
Take care not to damage the collector arms.
Avoid pouring sand inside the central pipe.
7. Fit the cover once again, pressing the clamp alter-
nately and uniformly until there is 5-10 mm betwe-
en flaps.
3.4. Start-up
1. Cleaning: Clean the swimming pool as well as pos-
sible 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. 10)
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 vessel. (LT Model)
Slightly open the bleeders available. (Fig. 11)
Close the pump filter cover and bleeders correctly,
so that they are watertinght.
5. Adjust the hours of operation of the equipment in
accordance with the volume of the swimming pool
and the flow supplied by the pump (see the table:
"Filtration capacity").
EXAMPLE:
For correct filtering of a 10 m
an FKB 300 unit with a BASIC pump:
SWIMMING POOL VOLUME x DAILY REPLENIS-
HMENTS = FLOW TO RECIRCULATE
10 m
3
FLOW TO RECIRCULATE ÷ PUMP FLOW =
HOURS OF OPERATION
40 m
3
The service time may be continuous or divided into
cycles.
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 pre-
filter and skimmers.
4. WINTER CARE
In winter the filtering installation must be protected
from the risk of frost. (Fig. 12)
If the equipment is not going to be used during the
winter period, the following operations must be per-
formed:
– 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.
