COMMISSIONING AND MAINtENANCE
9
Any gas leaks indoors can generate toxic gases if they come
into contact with naked flames or high temperature bodies,
in case of leaks, please air the rooms thoroughly.
9
Take anti-static precautions in case of weather conditions
where humidity is less than 40%.
9
Avoid using mobile phones.

In base alla Normativa CE n. 517/2014 su determinati gas floru-
rati ad effetto serra, è obbligatorio indicare la quantità totale
di refrigerante presente sistema installato. Tale informazione è
presente nella targhetta tecnica presente nell'unità esterna.

To write the tag:
—
note the quantity onto the label with indelible ink
—
place the refrigerant gas label on the outdoor unit

This unit contains fluorinated greenhouse gases covered
by the Kyoto protocol. Maintenance and disposal activities
must be carried out exclusively by skilled personnel.
9
Global warming potential of the R32 refrigerant gas: GWP=675

If necessary, the refrigerant must be recovered and not di-
spersed into the environment.

It is forbidden to disperse the refrigerant into the environ-
ment.
3.3
Ordinary maintenance
Routine maintenance is fundamental for keeping the equip-
ment efficient, safe and reliable. It can be performed periodi-
cally by the Technical Support Service, whose staff is technically
qualified and can use genuine spare parts, if necessary.
9
For units installed in a seaside environment, the mainte-
nance intervals shall be halved.
9
Original conditions must be restored after performing the
required maintenance operations.
9
All described operations MUST be carried out under the fol-
lowing conditions:
—
cold device
—
device NOT supplied with electric power
—
suitable personal protection equipment
0
Do not open the access covers and carry out technical or
cleaning activities before disconnecting the unit from the
power grid by positioning the system's main switch in the
"OFF" position.
ON
OFF
—
position the system's main switch in the "OFF" position.
9
Wait 10 minutes before touching the device electric compo-
nents.
9
Check with a tester that the voltage between the power
supply connectors of the main electronic board is lower
than 10 Vdc.
Yearly operations
The annual maintenance plan includes the following checks:
—
power supply voltage
—
electric connection tightening
—
status of cooling and hydraulic joint
—
finned coil cleaning
—
electric absorption
—
fan grille cleaning
Cleaning the heat exchanger fins
The thermal exchange bank must be cleaned with compressed
air.
Cleaning must be carried out at least once a year, according to
the location of the unit, as dirt accumulating between the fins
narrows the passage section and reduces the exchange capa-
bility.
—
check the alignment of the bank's aluminium fins and, if
necessary, straighten them with the appropriate comb
—
check that the condensate discharge pipe is clean
9
Do not use any means to accelerate the defrosting.
9
Do not use systems different from the ones indicated in this
manual.
Emptying of the evaporator
This operation may be necessary to perform reparations on the
low pressure side (evaporator), the device reallocation or the re-
placement of the indoor unit without losing the whole refrige-
rant charge.
Proceed as follows:
—
remove the covering plug from the shut-off valve
—
check that the three-way shut-off valve is fully open
—
let the device operate in cooling mode for 10 - 15 minutes
—
stop the device for about 3 minutes
