This air conditioner has the structure designed to drain water collected from dew, which forms on the back of the indoor unit, to the drain pan. Therefore, do not store the power cord and other parts at a height above the drain guide. Wall Drain guide Strong wind Fig. 8-5-1 CAUTION Installation in the following places may result in trouble. · A place where high-frequency waves are likely to be generated as from radio equipment, welders, and medical equipment.

Then tighten the nut with a spanner and torque wrench as shown in the figure. <Use of vacuum pump> (1) Connect the charge hose (A) from the manifold valve to the charge inlet of the gas side packed valve. (5) Close the low pressure side handle of manifold valve after vacuumizing and stop the vacuum pump. Continue vacuumizing more than 15 minutes and check the pressure gage indicates ­0, 1MPa (­76 cmHg). (7) Securely tighten the stem cap to each of the packed valve stems. CAUTION · Do not apply excess torque. Otherwise, the nut may crack depending on the installation conditions.
