Installation And Start-Up; Fitting Instructions - Espa FILTERKIT BASE Manual De Instrucciones

To perform the functions indicated, the unit is
principally formed of the filter, the pump and the
selector valve.
The selector valve may have 4 or 6 positions,
depending on the number of functions of each
equipment unit. The filtration unit has been
designed to comply with the EN 16713-1 standard.
2.1. Principal functions
ENSURE THAT THE PUMP IS NOT IN
OPERATION BEFORE CHANGING THE
POSITION OF THE VALVE.
2.1.1. Filtration
This consists in recirculating the water of the
swimming pool from the skimmer and overflow,
driving it by means of the pump through the filter
and returning the filtered water to the swimming
pool. (Fig. 1)
The operating time of the equipment depends on
the volume of water in the swimming pool and the
filtration capacity of the equipment (flow). See point
(3.4.) Start-up.
2.1.2 Pressure control
The pressure gauge permits control of filter
pressure. It is important to check the pressure at
regular intervals to ensure optimum equipment
operation.
When the pressure increases by 0,5kg/cm² in
relation to the initial reading the filter is reaching
saturation point, thus reducing filtering capacity.
When the pressure shows such an increase the
washing process must be carried out. It is therefore
important to observe and note down the pressure at
first start-up. The use of certain swimming-pool
accessories, such as the bottom-suction device,
can reduce filtering effectiveness and lead to
gradual saturation of the filter.
2.1.3. Washing
If the filter is saturated, it must be washed. This
consists of 2 stages:
a) Backwashing: countercurrent circulation of the
water through the filter and towards the outflow for
approximately 3 minutes. (Fig. 2)
b) Rinsing: circulation of water through the filter
towards the outflow, until the water is clear. (See
inspection window). In the absence of a window,
perform this operation for ½ - 1minute. (Fig. 3)
2.1.4. Recirculation – Bypass (only for units
with 6- position valves)
When the selector valve is in this position, the water
from the pump is recirculated directly towards the
swimming pool, without passing inside the filter.
Ensure that the pump is not in operation, turn the
valve to the "RECIRCULATION" position and start
up the pump.
To apply this process during the chemical treatment
of the water. (Fig. 4)
2.1.5. Emptying (only for units with 6-position
valves)
If the swimming pool does not have an outflow at
the bottom, it can be emptied by means of the
equipment pump. This function can also be used to
remove large particles of dirt from the bottom of the
pool with the pool bottom cleaner; in this way the
dirt will not pass through the filter. (Fig. 5)
2.1.6. Closed (only for units with 6-position
valves)
In this position all the functions are interrupted. This
is used to carry out maintenance work on the
filtering tank. (Fig. 6)

3. INSTALLATION AND START-UP

3.1. Typical installation diagram. (Fig. 7)

3.2. Fitting instructions

The equipment must be installed and fitted
by an authorised fitter.
Installation
accordance with the safety standards for
swimming pools, especially standard EN
60364-7- 702 and the particular standards
for each application.
For the safety of persons, it is imperative
that the filtration unit is installed at a
distance of
swimming pool and in compliance with the
regulations in force. If it is installed less
than 3.5m from the swimming pool, use of
this equipment is prohibited while the pool
is being used.
The power supply line must be protected by
an automatic shutoff device, a differential
circuit breaker with a cut-off current of no
more than 30mA.
Special care must be taken to prevent
water entering the pump motor or other live
electrical parts of the installation.
Check that
frequency correspond to those indicated on
the pump specifications plate.
The premises must be equipped with a
ventilation inlet to ensure the optimum
operation and reliability of the equipment.
