Refilling the refrigerant
Check the type of refrigerant to be used on the machine nameplate.
Precautions when adding R410A
Fill from the gas pipe in liquid form.
It is a mixed refrigerant, so adding it in gas form may cause the refrigerant composition to change, preventing normal operation.
1) Before filling, check whether the cylinder has a siphon attached or not. (It should have something like “liquid filling siphon
attached” displayed on it.)
• Be sure to use the R410A tools to ensure pressure and to prevent foreign objects entering.
NOTE
National implementation of EU regulation on certain fluorinated greenhouse gases may require to provide the appropriate official
national language on the unit. Therefore an additional multilingual fluorinated greenhouse gases label is supplied with the unit.
Sticking instructions are illustrated on the backside of that label.
Standby Electricity Saving
The standby electricity saving function turns off power supply to the outdoor unit and sets the indoor unit into
standby electricity saving mode, thus reducing the power consumption of the air conditioner.
The standby electricity saving function works on the following indoor unit.
CAUTION
• The standby electricity saving function cannot be used for models other than the specified ones.
Procedure for turning on standby electricity saving
function
1) Check that the main power supply is turned off. Turn it off if it
has not been turned off.
2) Remove the stop valve cover.
3) Disconnect the selective connector for standby electricity
saving.
4) Turn on the main power supply.
CAUTION
• Before connecting or disconnecting the selective connector for standby electricity saving, make sure that the main power
supply is turned off.
• The selective connector for standby electricity saving is required if an indoor unit other than the above applicable one is connected.
Filling a cylinder with an attached siphon
Stand the cylinder upright when
filling.
There is a siphon pipe inside, so the
cylinder need not be upside-down to
fill with liquid.
Turn the cylinder upside-down
when filling.
Filling other cylinders
Please fill in with indelible ink,
the factory refrigerant charge of the product,
the additional refrigerant amount charged in the field and
the total refrigerant charge
on the refrigerant charge label supplied with the product.
