• Refrigerant R410A in the system must be kept clean, dry, and tight. (a) Clean and Dry -- Foreign materials (including mineral oils such as SUNISO oil or moisture) should be prevented from getting into the system. (b) Tight -- R410A does not contain any chlorine, does not destroy the ozone layer, and does not reduce the earth’s protection again harmful ultraviolet radiation.

Page 8: Preparations Before Installation
CAUTION • The indoor and outdoor units and the power supply wiring and remote controller wire must be installed at least 40in. away from any televisions or radios. This is to prevent interference with picture and sound reception. (Interference may occur even at 40in. away depending on the reception quality.) (2) Ceiling height This product can be installed in ceilings up to 11-1/2ft.

5. INDOOR UNIT INSTALLATION Installing optional accessories (except for the decoration panel) before installing the indoor unit is easier. However, for existing ceilings, install fresh air inlet component kit and branch duct before installing the unit. As for the parts to be used for installation work, be sure to use the provided accessories and specified parts designated by our company.

<Ceiling work> (1-3) Adjust the unit to the right position for installation. (Refer to “4. PREPARATIONS BEFORE INSTALLATION-(1)”.) • Using the Installation guide (15) allows you to check the positions from the underside of the unit to the lower ceiling surface. Apply the short side of the cut-out section.
Page 12 CAUTION • Use a pipe cutter and flare suitable for the type of refrigerant. • Apply ester oil or ether oil around the flare section before connecting. • To prevent dust, moisture or other foreign matter from infiltrating the tube, either pinch the end or cover it with tape.
Page 13 Not recommendable but in case of emergency You must use a torque wrench but if you are obliged to install the unit without a torque wrench, you may follow the installation method mentioned below. When you keep on tightening the flare nut with a spanner, there is a point where the tightening torque suddenly increases.
Page 14: Drain Piping Work
CAUTION CAUTION TO BE TAKEN WHEN BRAZING REFRIGERANT PIPING “Do not use flux when brazing refrigerant piping. Therefore, use the phosphor copper brazing filler metal (BCuP-2/B-Cu93P-710/795) which does not require flux.” (Flux has extremely harmful influence on refrigerant piping systems. For instance, if the chlorine based flux is used, it will cause pipe corrosion or, in particular, if the flux contains fluorine, it will damage the refrigerant oil.) •...

Page 16 WHEN ELECTRIC WIRING WORK IS FINISHED • Add approximately 1/4gal. of water slowly from the air outlet and check drainage flow. • Check drainage flow during COOL running, explained under ‘‘12. TEST RUN’’. • Refer to the figure on the following after checking the draining of water, and mount the thermal insulation material for drainage (14) and thermal insulate the drain socket.
