9 Maintenance
9.1 General description
Maintenance must be done by authorized centres or by qualied personnel.
The maintenance allows to:
maintain the unit eciency
increase the life span of the equipment
assemble information and data to understand the state of the unit eciency and avoid possible damages
Before checking, please verify the following:
the electrical power supply line should be isolated at the beginning
the unit isolator is open, locked and equipped with the suitable warning
make sure no tension is present
After turning o the power, wait at least 5 minutes before accessing to the electrical panel or any other electrical component.
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 eected
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)

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 dierence between the temperature of the supply water and the condensation temperature: if the dierence is greater than 8°C–10°C it is advisable to clean the exchanger.
The clearing must be eected:
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 specic set-point that can be dened in 4 daily intervals and 3 user proles.
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 congured 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 dierent set-point, which is independent from that set for the Domestic Hot Water.
This function can be scheduled daily, weekly, at dierent time intervals.

10.5 Boiler management
Boiler management only for installation production
The conguration 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 conguration 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 qualied 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 inam­mable 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-qualied personnel may cause damage to persons, things or the unit itself. Always contact the qualied 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.
