Hitachi air core 600 Installation & Maintenance Manual page 4

• Do not turn on the lights until the entire operation is completed, if the lights are turned on
before the entire operation is completed, it may cause serious accidents such as electric
shock or fire.
• If the leaking air conditioner comes into direct contact with the flame, toxic gases may be
produced.
• Installation must comply with the regulations, regulations or standards for cabling
systems and equipment in each country, region or installation location.
• Do not use this unit with air or any other air conditioner not specified in the air hose,
excessive pressure can cause rupture.
• During the installation process, before starting the compressor, be sure to install the air
conditioner hose firmly. If the air hose is not properly installed and the 2-way or 3-way
valve is open, do not operate the compressor, otherwise it may cause abnormal
pressure in the cooling circuit until it breaks or may cause injury.
• When installing or repositioning an air conditioner, do not mix any other gases into the
cooling loop than the specified air conditioner (R32). If air or other gases enter the
refrigeration loop, the pressure in the loop can rise to abnormal levels and may cause
rupture or injury.
• In order for the air conditioner to work properly, install it according to the instructions in
this manual.
• To connect indoor equipment, outdoor equipment or branch boxes, air conditioning
ducts and wires should be purchased from a local dealer.

vacuum pump or air conditioner.
• Use vacuum pump assembly gauge and clean air filling hose between R32 or R410A,
respectively.
• Do not modify the unit, such as drilling holes in the air conditioner.
• During the pumping process, the air conditioner should ensure that the compressor is
turned off, and do not remove the extension hose with the compressor running and the
2-way or 3-way valve open before removing the air conditioner hose, otherwise it may
cause abnormal pressure in the cooling circuit, which can lead to rupture or injury.
