Important information regarding the refrigerant used
Refrigerant type:
R32
GWP
(1)
value:
550 *
(1)
GWP = global warming potential
The refrigerant quantity is indicated on the unit name plate.
* This value is based on F gas regulation (824/2006).
• Be sure to earth the air conditioner.
Do not earth the unit to a utility pipe, lightning conductor or telephone earth lead. Imperfect earthing may result in electric
shocks.
• Be sure to install an earth leakage circuit breaker.
Failure to install an earth leakage circuit breaker may result in electric shocks or fire.
• Do not use means to accelerate the defrosting process or to clean, other than those recommended by the
manufacturer.
• The appliance must be stored in a room without continuously operating ignition sources (for example: open
flames, an operating gas appliance or an operating electric heater).

• The appliance must be installed, operated and stored in a room with a floor area larger than 1.8m
2
.
• Comply with national gas regulations.
• Do not install the air conditioner at any place where there is a danger of flammable gas leakage.
In the event of a gas leakage, build-up of gas near the air conditioner may cause a fire to break out.
• While following the instructions in this installation manual, install drain piping to ensure proper drainage and
insulate piping to prevent condensation.
Improper drain piping may result in indoor water leakage and property damage.
• Tighten the flare nut according to the specified method such as with a torque wrench.
If the flare nut is too tight, it may crack after prolonged use, causing refrigerant leakage.
• Take adequate steps to prevent the outdoor unit being used as a shelter by small animals.
Small animals making contact with electrical parts can cause malfunctions, smoke or fire. Please instruct the customer to keep
the area around the unit clean.
• The temperature of refrigerant circuit will be high, please keep the inter-unit wire away from copper pipes that are not
thermally insulated.
• Only qualified personnel can handle, fill, purge and dispose of the refrigerant.
