NOTICE
Applicable legislation on fluorinated greenhouse gases
requires that the refrigerant charge of the unit is indicated
both in weight and CO

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.

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
Use an all-pole disconnection type breaker with at least
3 mm between the contact point gaps that provide 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.
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.
