Before accessing check with a multimeter that there are no residual stresses.
9.2 Inspections frequency
Perform an inspection every 6 months minimum.
The frequency, however, depends on the use.
In the event of frequent use it is recommended to plan inspections at shorter intervals:
frequent use (continuous or very intermittent use, near the operating limits, etc)
•
critical use (service necessary)
•
9.3 Unit booklet
It’s advisable to create a unit booklet to take notes of the unit interventions.
In this way it will be easier to adequately note the various interventions and aid any troubleshooting.
Report on the booklet:
date
•
type of intervention eected
•
intervention description
•
carried out measures etc.
•
9.4 Standby mode
If a long period of inactivity is foreseen:
turn o the power
•
avoid the risk of frost (empty the system or add glycol)
•
Turn o the power to avoid electrical risks or damages by lightning strikes.
With lower temperatures keep heaters turned on in of the electrical panel (option).
It’s recommended that the re-start after the stopping period is performed by a qualied technician, especially after seasonal stops or seasonal
switching.
When restarting, refer to what is indicated in the “start-up” section.

9.6 Air coil
Contact with the exchanger ns can cause cuts: wear protective gloves to perform the above described operations.
It is extremely important that the battery gives the maximum thermal exchange; therefore, its surface must be cleaned from dust and deposits.
Remove all impurities from the surface.
Using an air pressure gun, clean the aluminum surface of the battery; be careful to direct the air in the opposite direction of the fan air
movement.
Hold the gun parallel to the ns to avoid damages.
As an alternative, vacumn cleaner can be used to suck impurities from the air input side.
Verify that the aluminum ns are not bent or damaged, in the event of damages contact the authorized assistance center and get the ns
straightened in order to restore the initial condition for an optimal air ow.
9.7 Water side exchanger
It is very important for the exchanger to be able to provide the maximum thermal exchange, therefore it is essential for the inner surfaces to
be clean of dirt and incrustations.
Periodically check the dierence between the temperature of the supply water and the condensation temperature: if the dierence is greater
than 8°C–10°C it is advisable to clean the exchanger.
The clearing must be eected:
with circulation opposite to the usual one
•
with a speed at least 1,5 times higher than the nominal one
•
with an appropriate product moderately acid (95% water + 5% phosphoric acid)
•
after the cleaning rinse with water to inhibit the action of any residual product

Operation - CMACSX
The CMACSX module allows controlling the temperature of the Domestic Hot Water, by means of the temperature probe placed inside the
storage tank.
The control allows the production of Domestic Hot Water to a specic set-point that can be dened in 4 daily intervals and 3 user proles.
If the temperature of the Domestic Hot Water drops below a preset value (generally 40°C), the unit performs the “mode change” between
system and Domestic Hot Water production, driving a diverter valve that switches the ow from the system to the storage tank.
The request of DHW production has always the priority over the system and ends if the congured set-point has been reached or the set time
for the production of DHW has elapsed.
The Anti-legionella function allows removing the Legionella bacteria, which reside in the water storage tank.
These bacteria are removed if the water temperature exceeds 60°C for at least 30 consecutive minutes.
The anti-legionella function is managed by a dierent set-point, which is independent from that set for the Domestic Hot Water.
This function can be scheduled daily, weekly, at dierent time intervals.

10.5 Boiler management
Boiler management only for installation production
The conguration of the system involves 1 3-way diverting valve (E) between the heat pump and the auxiliary generator.
The heat pump acts as the main generator and is activated whenever there is a request from the system.
If the System set point has not been reached yet and the outdoor air temperature drops below the selected set point, the heat pump stops,
switches the 3-way valve (E) and, after a 120-second delay, it activates the auxiliary generator with its own set point.
If the outdoor air temperature remains below the selected set point, the auxiliary generator operates until it reaches the System’s set point.
If the air temperature rises above the selected set point, the control stops the auxiliary generator, switches the 3-way valve (E) and activates
the heat pump until it reaches the System’s set point.

Boiler managment for installation and DHW production
The system conguration consists of:
1 module to manage domestic hot water (CMACSX)
1 3-way diverting valve (E) between the heat pump and the auxiliary generator
1 3-way valve (D) to divert the ow towards the DHW storage tank
The heat pump acts as the main generator and is activated whenever there is a request from the system or a DHW request.
If the domestic hot water temperature drops below a set value, the CMACSX module sends the request to produce DHW to the heat pump and
controls the switching of the 3-way valve (D), so that it diverts the ow from the system to the DHW storage tank.
The heat pump switches the set point from the system’s value to the DHW value and produces DHW.
If the DHW set point has not been reached yet and the outdoor air temperature drops below the selected set point, the heat pump stops,
switches the 3-way valve (E) and, after a 120-second delay, it activates the auxiliary generator to produce DHW.
Via the CMACSX module, the heat pump switches the set point of the auxiliary generator from System production to DHW production through
a potential-free contact.
If the auxiliary generator is not designed to manage a double set point, set the DHW production value as a set point and provide for a
downstream mixing system to reach the correct system supply temperature.
If the outdoor air temperature remains below the selected set point, the auxiliary generator operates until it reaches the DHW set point.
If the air temperature rises above the selected set point, the control stops the auxiliary generator, switches the 3-way valve (E) and activates
the heat pump until it reaches the DHW set point.

12 Residual risks
General description
In this section the most common situations are indicated,as these cannot be
controlled by the manufacturer and could be a source of risk situations for
people or things.
Danger zone
This is an area in which only an authorised operator may work.
The danger zone is the area inside the unit which is accessible only with the
deliberate removal of protections or parts thereof.
Handling
The handling operations, if implemented without all of the protection
necesssary and without due caution, may cause the drop or the tipping of
the unit with the consequent damage, even serious, to persons, things or the
unit itself.
Handle the unit following the instructions provided in the present manual regarding the packaging and in compliance with the local regulations in force.
Should the refrigerant leak please refer to the refrigerant “Safety sheet”.
Installation
The incorrect installation of the unit could cause water leaks, condensate
accumulation, leaking of the refrigerant, electric shock, poor operation or
damage to the unit itself.
Check that the installation has been implemented by qualied technical
personnel only and that the instructions contained in the present manual
and the local regulations in force have been adhered to.
The installation of the unit in a place where even infrequent leaks of inammable gas and the accumulation of this gas in the area surrounding the area
occur could cause explosions or res.
Carefully check the positioning of the unit.
The installation of the unit in a place unsuited to support its weight and/or
guarantee adequate anchorage may result in consequent damage to things,
people or the unit itself.
Carefully check the positioning and the anchoring of the unit.
Easy access to the unit by children, unauthorised persons or animals may be
the source of accidents, some serious.
Install the unit in areas which are only accessible to authorised person and/or
provide protection against intrusion into the danger zone.
General risks
Smell of burning, smoke or other signals of serious anomalies may indicate a
situation which could cause damage to people, things or the unit itself.
Electrically isolate the unit (yellow-red isolator).
Contact the authorised service centre to identify and resolve the problem at
the source of the anomaly.
Accidental contact with exchange batteries, compressors, air delivery tubes
or other components may cause injuries and/or burns.
Always wear suitable clothing including protective gloves to work inside the
danger zone.
Maintenance and repair operations carried out by non-qualied personnel
may cause damage to persons, things or the unit itself.
Always contact the qualied assistance centre.
Failing to close the unit panels or failure to check the correct tightening of all
of the panelling xing screws may cause damage to persons, things or the
unit itself.
Periodically check that all of the panels are correctly closed and xed.
If there is a re the temperature of the refrigerant could reach values that increase the pressure to beyond the safety valve with the consequent possible
projection of the refrigerant itself or explosion of the circuit parts that remain
isolated by the closure of the tap.
Do not remain in the vicinity of the safety valve and never leave the refrigerating system taps closed.
Electric parts
An incomplete attachment line to the electric network or with incorrectly
sized cables and/or unsuitable protective devices can cause electric shocks,
intoxication, damage to the unit or res.
Carry out all of the work on the electric system referring to the electric layout
and the present manual ensuring the use of a system thereto dedicated.
An incorrect xing of the electric components cover may lead to the entry of
dust, water etc inside and may consequently electric shocks, damage to the
unit or res.
Always x the unit cover properly.
When the metallic mass of the unit is under voltage and is not correctly
connected to the earthing system it may be as source of electric shock and
electrocution.
Always pay particular attention to the implementation of the earthing
system connections.
Contact with parts under voltage accessible inside the unit after the removal
of the guards can cause electric shocks, burns and electrocution.
Open and padlock the general isolator prior to removing the guards and
signal work in progress with the appropriate sign.
Contact with parts that could be under voltage due to the start up of the unit
may cause electric shocks, burns and electrocution.
When voltage is necessary for the circuit open the isolator on the attachment
line of the unit itself, padlock it and display the appropriate warning sign.
Moving parts
Contact with the transmissions or with the fan aspiration can cause injuries.
Prior to entering the inside of the unit open the isolater situated on the connection line of the unit itself, padlock and display the appropriate warning
sign.
Contact with the fans can cause injury.
Prior to removing the protective grill or the fans, open the isolator on the
attachment line of the unit itself, padlock it and display the appropriate
warning sign.
Refrigerant
The intervention of the safety valve and the consequent expulsion of the gas
refrigerant may cause injuries and intoxication.
Always wear suitable clothing including protective gloves and eyeglasses for
operations inside the danger zone.
Should the refrigerant leak please refer to the refrigerant “Safety sheet”.
Contact between open ames or heat sources with the refrigerant or the
heating of the gas circuit under pressure (e.g. during welding operations)
may cause explosions or res.
Do not place any heat source inside the danger zone.
The maintenance or repair interventions which include welding must be
carried out with the system o.
Hydraulic parts
Defects in tubing, the attachments or the removal parts may cause a leak
or water projection with the consequent damages to people, things or
shortcircuit the unit.
