2 Charge refrigerant.
3 Check for refrigerant leaks after charging (see below)
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.
6.6 To fix the fluorinated greenhouse
gases label
1 Fill in the label as follows:

a 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.
b Factory refrigerant charge: see unit name plate
c Additional refrigerant amount charged
d Total refrigerant charge
e Quantity of fluorinated greenhouse gases of the total
refrigerant charge expressed as tonnes CO
f GWP = Global Warming Potential
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.

Electrical installation

DANGER: RISK OF ELECTROCUTION
WARNING
▪ All wiring MUST be performed by an authorised
electrician and MUST comply with the applicable
national wiring regulation.
▪ Make electrical connections to the fixed wiring.
▪ All components procured on-site and all electrical
construction MUST
legislation.
WARNING
ALWAYS use multicore cable for power supply cables.
WARNING
Use an all-pole disconnection type breaker with at least
3 mm between the contact point gaps that provides full
disconnection under overvoltage category III.

WARNING
If the supply cord is damaged, it MUST be replaced by the
manufacturer, its service agent or similarly qualified
persons in order to avoid a hazard.
WARNING
Do NOT connect the power supply to the indoor unit. This
could result in electrical shock or fire.
WARNING
▪ Do NOT use locally purchased electrical parts inside
the product.
▪ Do NOT branch the power supply for the drain pump,
etc. from the terminal block. This could result in
electrical shock or fire.
WARNING
Keep the interconnection wiring away from copper pipes
without thermal insulation as such pipes will be very hot.
DANGER: RISK OF ELECTROCUTION
All electrical parts (including thermistors) are powered by
the power supply. Do NOT touch them with bare hands.
7.1 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.
