Install this air conditioners by local regulations or standards. 2 3 W B 15WB 46 DB -5 DB 30 DB 15 DB 15.5 WB -20 WB NOTE: This air conditioners only is appliable of cooling or heating mode,do not operate cool and heat mode together, if operate cool and heat mode at the same time,air conditioner system will be fluctuated for large difference in temperature for changing operate mode.
SAFETY SUMMARY G Use refrigerant R410A in the refrigerant cycle. Do not charge oxygen, acetylene or other flammable and poisonous gases into the refrigerant cycle when performing a leakage test or an air-tight test. These types of gases are extremely dangerous and can cause an explosion.
Therefore, the utilization of the unit other than those indicated in these instructions is not recommended. Please contact your local agent, as the occasion arises. Hitachi s liability shall not cover defects arising from the alteration performed by a customer without Hitachi s consent in a written form. ATTENTION :...

Spindle Valve Torque (N m) Liquid After pipe and nut cap are connected,when test the air-tight , open the stop valve spindle cap to make sure valve is closed <Gas Valve> already(clock wise). Refrigerant Pressure Tighten nut cap below torque,great torque will bring on Hexagonal Wrench Tighten the cap with a torque refrigerant leakage of valve spindle.
Never use the refrigerant charged in the outdoor unit for air purging. Insufficient refrigerant will lead to failure. Thermal Insulation Finishing Work Wind tape from outside of thermal insulating of gas piping and liquid piping Indoor Unit Cover the flare nut and union of the piping connection with thermal insulation.
Caution of the Pressure by Check Joint When the pressure is measured, use the check joint of gas stop valve ((A) in the figure below) and use the check joint of liquid piping ((B) in the figure below). At that time, connect the pressure gauge according to the following table because of high pressure side and low pressure side changes by operation mode.
Additional Refrigerant Charge It is necessary additional refrigerant charge as follows. Additional Refrigerant Charge Calculation Although refrigerant has been charged into this unit, it is required that additional refrigerant be charged according to piping length. A. Determine an additional refrigerant quantity according to the following procedure, and charge it into the system. B.
Collecting Refrigerant Electrical Wiring When the refrigerant should be collected into the outdoor unit due to indoor/outdoor unit relocation, collect the refrigerant as follows. G Turn OFF the main power switch to the (1) Attach the manifold gauge to the gas stop indoor unit and the outdoor unit and wait for valve and the liquid stop valve.
