If a multilingual fluorinated greenhouse gases label is
delivered with the unit (see accessories), peel off the
applicable language and stick it on top of a.

NOTICE
Applicable legislation on fluorinated greenhouse gases
requires that the refrigerant charge of the unit is indicated
both in weight and CO
2
Formula to calculate the quantity in CO
tonnes: GWP value of the refrigerant × total refrigerant
charge [in kg] / 1000
Use the GWP value mentioned on the refrigerant charge
label.
2 Fix the label on the inside of the outdoor unit near the gas and
liquid stop valves.
16.9
To check refrigerant piping joints
for leaks after charging refrigerant
Tightness test of field-made refrigerant joints indoors
1 Use a leakage test method with a minimum sensitivity of 5 g of
refrigerant/year. Test leaks using a pressure of at least 0.25
times the maximum working pressure (see "PS High" on the
unit nameplate).
If a leak is detected
1 Recover the refrigerant, repair the joint, and repeat the test.
2 Perform the leak tests see
"15.3.4 To perform a leak
3 Charge refrigerant.
4 Check for refrigerant leaks after charging (see above).

About electrical compliance
This equipment complies with:
▪ EN/IEC 61000‑3‑11 provided that the system impedance Z
less than or equal to Z
at the interface point between the user's
max
supply and the public system.
▪ EN/IEC
61000‑3‑11
=
Standard setting the limits for voltage changes, voltage
fluctuations and flicker in public low-voltage supply systems for
equipment with rated current ≤75 A.
▪ 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 system impedance Z
▪ EN/IEC 61000‑3‑12 provided that the short-circuit power S
greater than or equal to the minimum S
point between the user's supply and the public system.
▪ EN/IEC
61000‑3‑12
=
Standard setting the limits for harmonic currents produced by
equipment connected to public low-voltage 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 short-circuit power S
