5 EQUIPMENT DESCRIPTION

5.1 PARTICULARS AND FUNCTION

This equipment is used for the water treatment of the pool for human bathing. The aim is to

guarantee the filtration and to keep suspended matter not withheld by the traditional filters baskets

installed up stream of the system.

The AQUA s.p.a sand filter has been manufactured to hold materials and suspended matter of 0,4

Filters should operate only with:

-aqueduct or ground water

-seawater;

-water mixed with sodium hypochlorite in compliance with the UNI 901:2002 rule in a

solution of max 0,2 mg/l ( 2 ppm).

The equipment can be submitted to the working and burst pressure of:

ATTENTION:

Before the installation check that the inlet system, connected to

the filter, is provided with suitable devices which limit and prevent

the overflow of the maximum pressure inside the filtration system.

The fluid temperature used by the equipment should be included in the following range:

Tmin: +5°C

Tmax: +40°C

ATTENTION:

If it is provided that the fluid temperature can go below the

freezing point, isolate the equipment from the inlet system

connected to it and empty it, according to the conditions specified

in the maintenance section.

6 RISKS CONNECTED TO THE EQUIPMENT

6.1 UNIVERSALITY

6.3 RISKS FOR AN INCORRECT USE

In addition to the risks presciently underlined, it is possible to suppose that, although it has been

indicated more than once how to behave properly to limit the risks, there could be situations of

anomalous behaviour (incorrect use).

PICTURE 7.1: SIGNS LIST

8 TRANSPORT AND INTERNAL MOVING

The following specifications are to be considered:

It is recommended the use of qualified and specialized staff to move, transport and install the

equipment. Moving should be executed by lifting the equipment according to the following

specifications:

by the edge with open lid;

by the base;

For short moving it is possible to use a fork lift and/or manual trolley.

ATTENTION:

carry out all the operations with caution AND RISE THE

EQUIPMENT BY FOLLOWING THE INDICATED ZONE

ATTENTION:

it is necessary to follow the instructions reported in this

handbook to rise and to move the equipment.

9 INSTALLATION

9.1 NORMAL WORKING

Connection should be executed by authorized and qualified staff.

Equipment’s connection should be linked to the pool system circuit.

Connection should be done by using threaded pipes union which are included in the equipment,

the thread and the diameter are indicated in the components card.

Pipe union exit , included in the equipment, should be connected by a glued smooth pipe (PVC)

During the normal working, the equipment should be placed in a covered and dry area protected

from the direct sunlight irradiation and from heat.

For proper working conditions, the water temperature should range between +5°C and +40°C.

The filter has a flow stream direction –which should be respected –these are indicated by the

arrows situated near the pipe unions.

9.2 STORAGE

During an eventual storage the equipment should be kept in a covered and dry place.

-INSTRUCTION AND MAINTENANCE MANUAL L0200200 REV.7 12/04/2021

The equipment should be protected from eventual water sprinklings, dust, humidity, collision or

accidental damages.

Advisable room temperature should be included between 0°C and +50°C.

9.3 STARTING

Check carefully that the components aren’t damaged because of transport collisions .

if any part is damaged or it is not in keeping with the original condition of supplying, don’t make

the system work and provide for the reparation or for the substitution at the assistance centre.

Check that all the filter connection pipes and the valves are closed.

9.4 REFILLING

Refill the filter by putting in the filtering material from the hole lid.

The Filter media sand used must have the following characteristics:

material.

Refill should be done until the water level overflows the filter’s edge.

ATTENTION:

Check that the spreading of the water in excess doesn’t cause

damages and that there aren’t any nearby voltage and/or electric

component parts present were the excess water could be in

contact with.

-INSTRUCTION AND MAINTENANCE MANUAL L0200200 REV.7 12/04/2021

▪Assemble the pressure gauge on the lid in the proper hole (by the threaded hole or by the

proper back nut and O-ring);

▪Place the lid

▪Put the clamp to close the lid and the filter top

▪Place the 2 nuts in the clamp

▪Close the clamp using the screws, until the two side are coincident. Do not over-screw!

9.6 STARTING

Open slowly the valves situated on the connection pipe.

Check that there are no water leaks.

9.7 WORKING

The equipment carries out the filtration of the water according towhat is described in this handbook.

For a good performance of the filter and for a good management of the system connected to it,

there are further functions that should be considered and suggested.

By a different set up of the multi-port valve connected to the filter (when models are included) it

is possible to carry out these other functions.

A 6 way valve has the following main working positions:

the operating conditions of each position are described in detail hereafter

ATTENTION:

In case of water leaks, close immediately the filter valves and

proceed with an examination of the system.

1 - filtration

2 - backwash

3 - rinsing

4 - waste

5 - circulation

6 - lock
