9 Maintenance
9.1 General description
Maintenance must be done by authorized centres or by qualied personnel.
The maintenance allows to:
maintain the unit eciency
•
reduce the deterioration speed to whom every equipment is subject over time
•
assemble information and data to understand the state of the unit eciency and avoid possible damages
•
Before checking, please verify the following:
the electrical power supply line should be sectioned at the beginning
•
the line sectionalizing device is open, locked and equipped with the suitable warning
•
make sure no tension is present
•
9.2 Inspections frequency
Perform an inspection every 6 months of unit operating.
The frequency, however, depends on the use.
In the event of frequent use it is recommended to plan inspections at close 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 extremely rigid temperatures keep fed heating resistances of the electrical panel (option).
It’s recommended that the starting-up after the stopping period is performed by a qualied technician, especially after seasonal stops or
seasonal switch.
When restarting, refer to what is indicated in the “start-up” section.
Schedule technical assistance in advance to avoid hitches and to guarantee that the system can be used when required.

* European regulation 303/2008
Refer to the local actuation regulations; in short and just as an indication the regulation order as follow. Companies and technicians that eect
interventions of installation, maintenance/repairs, leak control and recovery must be CERTIFIED as expected by the local regulations. The leak
control must be eected with annual renewal.
9.7 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, an aspirator 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 battery
“ironed out” in order to restore the initial condition for an optimal air ow.
9.8 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 rince with water to inhibe the detergent rests
•

10.3 Directive EC RAEE
The units covered by the legislation in question are marked with the symbol on the side.
With the aim of protecting the environment, all of our units are produced in compliance with Directive EC on waste electrical and electronic
equipment (RAEE).
The potential eects on the environment and on human health due to the presence of hazardous substances are shown in the use and
maintenance manual in the section on residual risks.
Information in addition to that indicated below, if required, can be obtained from the manufacturer/distributor/importer, who are responsible
for the collection/handling of waste originating from equipment covered by EC-RAEE. This information is also available from the retailer who
sold this appliance or from the local authorities who handle waste.
Directive EC-RAEE requires disposal and recycling of electrical and electronic equipment as described therein to be handled through
appropriate collection, in suitable centres, separate from collection for the disposal of mixed urban waste.

11 Residual risks
General description
In this section the most common situations are signalled,as these
cannot be controlled by the manufacturer these 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 fall 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 gas refrigerant leak please refer to the refrigerant “Safety
sheet”.
Installation
An incorrect installation of the unit could cause water leaks, condensate accumulation, leaking of the refrigerant, electric shock, bad
functioning 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 cause the fall or the
tipping of the unit with the 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 damge 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 favour the
entry of dust, water etc inside and may consequently can 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 shield.
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 shield.
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
suitable sign.
Contact with the fans can cause incurie.
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 gas 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.
