16.6 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 "15.3.2To perform a leak test"[434].
3 Charge refrigerant.
4 Check for refrigerant leaks after charging (see above).
17 Electrical installation
CAUTION
See "2 Specific installer safety instructions" [4 5] to make
sure this installation complies with all safety regulations.
17.1 About electrical compliance
This equipment complies with:
▪ EN/IEC 61000‑3‑12 provided that the short-circuit 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 61000‑3‑12 = European/International Technical
Standard setting the limits for harmonic currents produced by
equipment connected to public low-voltage systems with input
current >16A and ≤75A 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
sc
greater than or equal to the
minimum S
sc
value.

17.2 Specifications of standard wiring
components
NOTICE
We recommend using solid (single-core) wires. If stranded
wires are used, slightly twist the strands to consolidate the
end of the conductor for either direct use in the terminal
clamp or insertion in a round crimp-style terminal. Details
are described in "Guidelines when connecting the electrical
wiring" in the installer reference guide.
