ADOPTION OF NEW REFRIGERANT This Air Conditioner is a new type which adopts a new refrigerant HFC (R410A) instead of the conventional refrigerant R22 in order to prevent destruction of the ozone layer. WARNING Cleaning of the air filter and other parts of the air filter involves dangerous work in high places, so be sure to have a service person do it. Do not attempt it yourself. The cleaning diagram for the air filter is there for the service person, and not for the customer. RAV-SM1100AT-E RAV-

After unpacking the unit, examine it carefully if there are possible damage. Do not install in a place that might increase the vibration of the unit. To avoid personal injury (with sharp edges), be careful when handling parts. Perform installation work properly according to the Installation Manual. Inappropriate installation may result in water leakage, electric shock or fire. When the air conditioner is installed in a small room, provide appropriate measures to ensure that the concent

7 FINAL INSTALLATION CHECKS Check and Test Operation For R410A, use the leak detector exclusively manufactured for HFC refrigerant (R410A, R134a, etc.). The conventional leak detector for HCFC refrigerant (R22, etc.) cannot be used because its sensitivity for HFC * refrigerant lowers to approx. 1/40. • Pressure of R410A is approx. 1.6 times higher than that of R22. If installation work is incompletely finished, a gas leakage may occur when pressure rises during operation. Therefore, be sure to t
