.
3.4.4
To charge refrigerant
WARNING
▪ Only use R410A as refrigerant. Other substances may
cause explosions and accidents.
▪ R410A contains fluorinated greenhouse gases covered
by the Kyoto Protocol. Its global warming potential
value is 1975. Do NOT vent these gases into the
atmosphere.
▪ When charging refrigerant, always use protective
gloves and safety glasses.
Prerequisite:
Before charging refrigerant, make sure the refrigerant
piping is connected and checked (leak test and vacuum drying).
1
Connect the refrigerant cylinder to both the service port of the
gas stop valve and the service port of the liquid stop valve.
2
Charge the additional refrigerant amount.
3
Open the stop valves.
3.4.5
To fix the fluorinated greenhouse gases
label
1
Fill in the label as follows:
c
b
a
a
Factory refrigerant charge: see unit name plate
b
Additional refrigerant amount charged
c
Total refrigerant charge
2
The filled out label must be adhered on the inside of the product
and in the proximity of the product charging port (e.g., on the
inside of the service cover).

Connecting the electrical wiring
DANGER: RISK OF ELECTROCUTION
WARNING
ALWAYS use multicore cable for power supply cables.
CAUTION
For use of units in applications with temperature alarm
settings it is recommended to foresee a delay of 10
minutes for signalling the alarm in case the alarm
temperature is exceeded. The unit may stop for several
minutes during normal operation for "defrosting the unit", or
when in "thermostat stop" operation.

About electrical compliance
A AZQS125_Y1
Equipment complying with EN/IEC 61000312 (European/
International Technical Standard setting the limits for harmonic
currents produced by equipment connected to public lowvoltage
systems with input current >16 A and ≤75 A per phase.).
AZQS140_Y1
Equipment complying with:
▪
EN/IEC 61000312
provided that the shortcircuit power S
sc
is
greater than or equal to the minimum S
sc
value at the interface
point between the user's supply and the public system.
▪ EN/IEC
61000312
=
European/International
Technical
Standard setting the limits for harmonic currents produced by
equipment connected to public lowvoltage systems with input
current >16 A and ≤75 A per phase.
▪ It is the responsibility of the installer or user of the equipment to
ensure, by consultation with the distribution network operator if
necessary, that the equipment is connected only to a supply
with a shortcircuit power S
sc
greater than or equal to the
minimum S
sc
value.
