4 General description of the operation

The dirt separator strainer consists of a series of elements that make it possible to obtain a product capable of carrying out a constant and continuous
filtration of the system water and automatic cleaning.

2"

45

The device is used only in central heating systems to remove dirt and impurities from the circuit progressively and completely.
The device must not be used by persons (including children) with impaired physical, sensory or mental capabilities, or lack of experience
and knowledge, unless they are instructed.
Any use of the device other than its intended use is prohibited.

4.1 Operating principle

This device flushes the system circuit medium by direct action through the direct action of passing through the specific filtering elements appropriately
arranged inside the body. The specific filtering mesh allows the removal of impurities that are deposited on the external surface of the strainers.
The very selective mesh filters particles with a diameter of 30 μm at the first passage and separates dirt particles up to 2 μm. At the same time, ferrous
particles are separated out by the magnets on the surface of the filter element.

Automatic cleaning of the filtering elements takes place mechanically by means of washing with pressurised mains water while the filtering elements
rotate.
In all its functional phases - operation, cleaning,filling and draining - the device is controlled by a special digital regulator, which can also be managed
remotely using a BMS system running MODBUS-RTU protocol.

This device operates according to different operating steps:

- filtration/ normal operation

- filtering elements cleaning

- circuit filling and operating conditions reset

The digital regulator manages the opening status of the inlet and load/drain valves, together with the strainers rotation motor during the cleaning. The
cleaning phase is automatically activated according to a preset pressure drop value or in a programmed way.
Depending on the type of system, the device can be combined with others for parallel operation.

6

4.2 Filtration

During normal operation, the medium coming from the system enters in the strainer body through the motorised ball valve V1. The medium is forced
to pass through the filtration discs, then it is conveyed into the central part until it comes out of the device through the clapet check valve.

4.3 Filtering elements cleaning

It can be activated manually, by time or automatically by controlling the medium pressure drop between internal pressure and pressure detected after
the filtering elements. The choice of the type of operation is carried out by the regulator. During the first cleaning phase (emptying) the inlet ball valve V1
closes while the clapet check valve prevents the system backflow. Once the inlet valve V1 is completely closed, the drain valve V3 is opened, located
in the lower part of the device. When the vacuum breaker valve, present in the upper part of the strainer body, is opened it allows the progressive
draining of the tank, causing part of the dirt to come out.

During the second cleaning phase (mechanical cleaning with water injection), the two-way solenoid valve V2 (equipped with check valve) is opened
injecting water from the water mains. In order to perform an effective cleaning, a minimum dynamic pressure of 3 bar must be guaranteed during
washing and the installation of an anti-backflow system is mandatory to protect the aqueduct network (apply according to local regulations in force).
At the same time the shaft on which the filtering discs are clamped is rotated by means of the motor M1, in order to allow the fixed brushes to clean
their surface and to clean the magnets.

4.4 Circuit filling and operating conditions restoring

At the end of the cleaning phase the initial conditions are restored, in order to continue with the normal filtration. The drain valve V3 is closed and
the rotation of the motor M1 is stopped. The strainer can be filled in two ways: with mains water through the solenoid valve V2 or using the system
circuit through the valve V1. This second option is preferable when the water in the heating circuit is treated and contains additives. The filling action
is gradual until the pressure detected in the system is reached. During this phase the air vent valve starts to expel the air in the tank and allows
optimal filling.

Pipes with suitable mechanical characteristics must be used for the installation: use pipes made of metal material adequately fixed to
support structures in order to not mechanically overload the connections and the legs of the device and in way to guarantee a fixed
position of the pipes, also during installation and commissioning.

The device must be installed according to the diagrams given in this manual. It must compulsorily be installed on the return circuit, to
collect the impurities present in the circuit, especially during the system activation phase (closing the by-pass valve at the same time),
before they can reach the boiler.

The drain system must be operated in way that it does not prevent normal operation, avoiding counter pressure and must not endanger
people or things. It must be conveyed into a dedicated pipe or collecting tank. Check compliance with local standards and regulations
regarding the filtration water draining into the sewage system, depending on the substances present in the water and in the sludge
collected and the temperature of the medium.

13

It is possible to adjust the drain in the most appropriate direction rotating the motorised ball drain valve and its fitting after loosening the cap. Take
care not to bend-stress the valve. This operation must be carried out before commissioning, with a completely empty and pressure-free device.

The device drains the liquid collected that can be at high temperatures (> 50°C), depending on the characteristics of the system in which
it is installed: use appropriate precautions to comply with local regulations in force and concerning the water drain.

To prevent contamination of the drinking water network and to avoid backflow phenomena, install a hydraulic backflow preventer and a
suitable strainer upstream of the strainer cleaning solenoid valve.

Limit as much as possible the length of the domestic pipes used for cleaning: use water hammer arrester or other devices to suppress
instantaneous overpressure that may occur during operation.

The domestic water inlet line for strainer washing may be subject to thermal overpressure: install suitable safety relief valves or expansion
vessels.

The domestic hot water inlet line may be subject to freezing risk. Provide suitable insulation or systems to avoid ice formation.

To allow an easier installation it is possible to invert the position of the inlet valve V1 with the automatic air vent having the same 2 1/2” thread. This
operation must be carried out during installation, with a pressure-free and completely empty strainer.

NOTE. The regulator is easily adjustable, making the information reading easy in every direction

17

Cleaning on instantaneous Dp

During normal operation, the device monitors the strainer clogging status, by measuring the differential pressure between inlet and outlet of the strainer
elements measured by the probes S1 and S2. When the difference exceeds a value set and modifiable by the user, an automatic strainer cleaning
cycle is immediately started.

Cleaning on delayed Dp

When the DP exceeds a predefined value (the same used to start the instantaneous cleaning), the cleaning is programmed to be performed but at a
time specified by the user.

Scheduled cleaning

It is possible to carry out a cleaning cycle on a specific day of the week, at a specific time or on several days of the same week. The device is cleaned
anyway even if the maximum set Dp value is not exceeded during operation. Cleaning can be scheduled for a particular day of the month, every two
months, every three months or every six months.

Initial cleaning

This function can be used after washing the system or anyway whenever an extraordinary cleaning of the system is necessary. Before starting this
function it is necessary to configure the duration. When the set Dp is reached, a washing cycle is immediately started. When the set number of
hours is reached, the first system cleaning function stops and the normal operating mode starts again, with the washes time management (e.g. once
a week) and/or based on the normal operation Dp value.

Manual forcing

It is possible to start the operating status through the forcing function, from the user interface or from remote (via bus). Once the required activation is
completed, the device returns to normal operation. Forcing allows, from the user interface, to individually start the cleaning, sleep, additive addition,
sensor control cycles.

Sleep

The sleep mode temporarily deactivates the device, setting it in a waiting status, with the valve V1 closing and without any control on the operation.
This status allows the device to be deactivated for a set time, for example when the system is shut down in the summer. At the end of the sleep
phase, the device resumes normal operation. The notifications for alarms remain active.

Use of additives

Additives can be added to the system medium activating the appropriate function. In this case the system is
set in stand by, after having carried out a forced cleaning cycle with a view to reducing as much as possible the
use of the water in the network, taking advantage of the tank emptying. During the waiting phase it is possible
to insert the necessary additives into the device using the 1” cap located in the upper part of the strainer, see
the characteristic components drawing. Carefully check the cap watertight closing, in order to prevent leakage
or flooding.

Additives must be in liquid form and must be added carefully and slowly to prevent accidental spills

Check the compatibility between the type of additives used and the dirt separator strainer materials. Any
incompatibility can cause serious damage to the machine, to people and property. Avoid contact with
skin and eyes. Avoid inhalation, use personal protective equipment. Do not disperse in the environment.
Refer to the safety data sheet and the technical documentation of the product. It is advisable to insert
max 40l of additives. If necessary, the function can be executed several times.

Sensors check

The regulator periodically checks the correct operation of the sensors. This procedure can be carried out manually through the item on the regulator
menu.

Drain temperature limitation

The system is provided with a function to cool the water drain when the temperature is higher
than a given value (that can be changed). During cleaning, if the system detects that the medium
temperature is higher than the admissible temperature, the activation of a specific G. OUT relay is
activated, which remains active until the drain ends.

The activation of the G. OUT relay must be used by the user to provide a system for reducing the drain water temperature of the device,
for example through a valve that injects cold water into the drain. Check the local regulations in force.

Faults

Abnormal operating conditions do not stop the operation of the device but are indicated on the display and allow to prevent more serious
problems (red LED flashing on the front panel). For more details about the alarms, refer to the "programming manual" code H0005275.

Alarms

In the event of serious problems that compromise the system safety conditions, it is set into a locked state. The relative status is shown
on the display (red fixed LED on the front panel), in addition the "ALARM" relay sets to the closed position. The latter may possibly be
connected to an optical and/or acoustic alarm system. For more details on the symbols related to the alarms, refer to the "programming
manual" code H0005275.

18

11 Commissioning

Commissioning must be carried out according to the regulations in force by qualified personnel.
Check that the cold water supply pressures are within the operating limits of the device.
Check that the temperature of the hot drain water has a value complying with the regulations in force.

NOTE. To ensure the strainer correct operation, check that the air vent cap is sufficiently loose (1/2 turn from
completely closed).

Attention: the device performs a check during the filling phase from V2 at the end of the wash and
if the drain cocks is left closed, an alarm is generated. The device checks the correct opening of the
air vent to avoid injecting air into the system after each cleaning with filling from the domestic line.

For all information regarding the strainer digital regulator management, refer to the programming manual H0005275

At the first start-up, a careful analysis must be carried out to check that there are no leaks and the assembly is correct: the filling must be carried out
gradually in order to allow the correct expulsion of air by the vent valve.
Once the seals have been checked, the device can be electrically supplied: once the system is electrically supplied, it performs a series of checking
operations before starting the filtering function. After providing electric supply or after a reset, the system closes the inlet and drain valve and opens
again the inlet valve after carrying out a filling operation: these steps allow to limit the amount of water in the system drained and return the system
to the correct operating conditions.

Check that the pressure in the domestic water mains is in the strainer operating range (minimum 3 bar) to guarantee an effective cleaning of the
filtering discs.

11.1 Filling and hydraulic test under pressure

Important! Do not supply electricity to the controller until it is indicated.

1. Check that the inlet valve is in the open position and if necessary move it manually until it reaches the complete valve opening.

2. Check that the drain valve is in the closed position and if necessary move it manually until it reaches the closed position.

3. Check that the controller is not electrically supplied.

4. Check that the air vent cap opens.

5. Slowly open the shut-off valve upstream of the device inlet and pressurize the system.

6. Wait for the device to fill.

7. Check for leaks: if leaks or seepage are found, close the shut-off valve upstream of the device and correct the anomalies found. Now it is possible
to wait until the qualified personnel arrive to make the electrical connections for the device electric supply.

8. With pressurised device, power the controller: if it was previously electrically supplied or if an alarm was present, perform a "Device reset".

9. After a few seconds the yellow light will turn on to indicate that the device is carrying out some operations (filling and internal checks).

10. Wait for the yellow light to go off: in the meantime it is still possible to access the internal device configuration menus to set the date and time
and the type of cleaning to be performed.

11.2 First start-up

When the filtering system is started up for the first time, the "initial cleaning" function can be activated in the regulator menu. This function can be used
to wash the system using the medium contained in the system. This avoids to drain large quantities of medium and avoids the need for complicated
venting operations. When the set differential is reached, a washing cycle is immediately started. The system stops the initial cleaning function when the

set time is reached or when the DP is lower than the set one. Depending on the type of installation it may be necessary to close the by-pass valve.
Check that the flow rates are compatible with the characteristics of the strainer and with other elements of the system

System stop procedure

Before turning off the regulator it is necessary to stop the flow of liquid to be filtered closing the system input motorised valve (V1). Turn
off the electric supply to the regulator and manually close the inlet valve (V1).

System prolonged closing

If the system is closed, remove the electric supply to the regulator, manually close the inlet valve (V1).

12 Maintenance

Introduction

Never perform maintenance and control operations with wet body parts. Wear the accident prevention equipment provided for by the regulations in
force.
Inspection and maintenance must always be carried out with the strainer stopped and without pressure. All operations must be performed by skilled
personnel authorized by the manufacturer to avoid damage to the internal parts. Failure to comply with these rules relieves the manufacturer of causes
for damage to persons and property and causes the loss of the warranty for damage to internal parts.

CLEARLY INDICATE THAT THE STRAINER IS IN MAINTENANCE APPLYING AN APPROPRIATE INDICATIONN SIGN.

Periodic checks

It is recommended to perform a preventive check of the strainer working status to avoid irreparable damage. It is recommended to perform a check
at least every 12 months.
To check the correct operation of all the strainer components it is necessary to carry out some periodic checks such as:

- Alarms history check

Note down the alarms that have occurred since the last check and carry out an analysis of the possible causes that triggered them.

- Anomalies history check

Note down the anomalies that have occurred since the last check and make an analysis of the possible causes that triggered them.

- Check that there are no leaks from the device

Check that there are no leaks from the device and from the drain valve.

- Check the correct operation of the controller and of the device elements

After having shut-off the inlet and the drain, check the operation of the various parts by means of manual forcing.
Check the actuators and the motor and the sensors pressure reading.

- Cables visual check

Check that the electric supply cable and the other cables do not show signs of degradation of the insulating sheath (hardening/cuts or tears).

- Check the earthing

Perform a visual check of the earth cable and the device earthing quality according to the regulations in force.
Minimum frequency: yearly or according to current legislation if more frequent.

- Verification of protection devices and electrical part command

Check the protection circuit breakers installed upstream of the device. Check the electric supply cut-off devices.
Minimum frequency: yearly or according to current legislation if more frequent.

- Installation check

Check the solidity and validity of the installation. Check that there are no signs of corrosion on the legs of the device and on the fixing bolts to the

ground.

- General check

Perform a general visual check of the device.

- Automatic air vent strainer cleaning

To carry out the periodic cleaning of the strainer on the automatic air vent valve, check that the strainer
is not pressurized, access the strainer unscrewing the 2 1/2” cap using the appropriate key. Clean the
strainer washing it under running water. Refit the strainer checking the status of the O-ring and replace
it if necessary. Tighten the nut checking for leakage or seepage.

Extraordinary maintenance

Carrying out regular periodic checks, no other type of intervention is required for extraordinary maintenance except in cases of damage due to external
causes or incorrect installations.

22

Residual risks

In case of malfunction of the device, remove the electric supply and, if necessary, close the drain valve. To facilitate checking and maintenance
operations it is recommended to close the inlet valve of the device to allow its cooling: in this condition, check that the flow rate in the various
circulators of the system is sufficient. If it is necessary to interrupt the cycle in progress (cleaning, additive addition or sensors check) it is necessary to
reset the device: this operation cancels all the alarms and anomalies present and restores the pressures necessary for filtration. To restore the correct
operating conditions it is necessary to wait for the time necessary for the correct switching of the valves and the device filling up.
Given the presence of various potentially dangerous factors (high temperature of the water and surfaces, electrical voltage, high weight of the
device, possible collection of toxic and non-drinking liquids) all operations must be carried out by qualified technical personnel, according to current
regulations and being very careful to the operations performed and the status of the device. During the device transport and handling it is possible that
some seals and the leg support nuts may come loose. Perform a visual check and make sure that the device legs nuts are tightened with a torque of
25 Nm. Do not remove the nuts and bolts used for fastening the legs. Do not remove or loosen the bolts used for fastening the cover.

Attention during draining and/or maintenance, if the pressure is not discharged correctly, it is possible that part of the
liquid contained may splash: use a mask, gloves and protective devices to avoid contact of hot and/or aggressive liquids
with eyes, skin and various parts of the body. During handling, installation and maintenance use protective gloves.

Always check the presence and correct installation of the insulation: if there is no insulation, avoid the flow of hot water. Always check
the presence and correct installation of the gearmotor shaft protection: if this protective device is not installed, do not start the cleaning
cycles, do not add additives and do not use the motor.

Do not open the controller without having first cut-off the electrical supply through a suitable cut-off device: do not electrically supply
the device if the controller or one of its components are open and/or do not have the protections against contact with live parts.

To avoid malfunctions and damage to people or property, always use protective devices suitable to ensure compliance with the maximum pressures
and the maximum and minimum operating temperatures stated by the manufacturer in all conditions of use. The device must not be installed in
contact or near sources of heat and/or fuels: respect a minimum free distance around the device of 50 cm.
Maintenance must only be carried out by qualified technical personnel: before working on the device, all necessary measures must be taken to
ensure safety of the device and of all its parts. This safety condition must be guaranteed until the device is put back into service and must take into
consideration all possible sources of danger such as (and not exclusive): electrical dangers (electrocution, projection of incandescent material, etc.),
thermal dangers (burns), mechanical dangers (abrasions, bruises, etc...), chemical dangers related to the liquid contained and hydraulic dangers
(flooding, etc...).
