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 Greenhouse gas emissions of the total refrigerant charge
expressed as tonnes CO
f GWP = Global warming potential
NOTICE
In Europe, the greenhouse gas emissions of the total
refrigerant charge in the system (expressed as tonnes CO
equivalent) is used to determine the maintenance intervals.
Follow the applicable legislation.
Formula to calculate the greenhouse gas emissions:
GWP value of the refrigerant × Total refrigerant charge [in
kg] / 1000
2 Fix the label on the inside of the outdoor unit near the gas and
liquid stop valves.

Connecting the electrical wiring

DANGER: RISK OF ELECTROCUTION
WARNING
▪ All wiring MUST be performed by an authorised
electrician and MUST comply with the applicable
legislation.
▪ 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
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.
DANGER: RISK OF ELECTROCUTION
Disconnect the power supply for more than 10 minutes,
and measure the voltage at the terminals of main circuit
capacitors or electrical components before servicing. The
voltage MUST be less than 50 V DC before you can touch
electrical components. For the location of the terminals,
see the wiring diagram.
