<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 15 • Make sure that heat insulation work is executed on the following 2 spots to prevent any possible water leak- age due to dew condensation. • Indoor drain pipe • Drain socket Metal Metal Large sealing pad (10) clamp (2) clamp (2) (accessory) (accessory)
- 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 OPERATION’’. • 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.
