Safety Precautions

Ventilate before operating air conditioner
when gas leaked out.
• It may cause explosion, fire, and burn.
If the air conditioner is installed in a small room, measures must be taken to prevent the
refrigerant concentration from exceeding the safety limit when the refrigerant leaks.
• Consult the dealer regarding the appropriate measures to prevent the safety limit from being exceed-
ed. Should the refrigerant leak and cause the safety limit to be exceeded, harzards due to lack of oxy-
gen in the room could result.
Don't use the existing manifold gage for R22
refrigerant.
• Use the manifold gage for high pressure (R410A)
as possible as for stable refrigerant filling.

Don't mix and use the R22 pipe and the
installation appliances that were used until
now
• Mixing the oil of R22 and R410A may cause
