Hitachi AirCore 700 Operation Installation Maintenance Manual page 8

1. Safety Summary
•
If the supply cord is damaged, it must be replaced by the manufacturer, its service agent or similarly
qualified persons in order to avoid a hazard.
•
Means for disconnection from the supply mains, which have a contact separation in all poles that
provide full disconnection under overvoltage category III conditions, must be incorporated in the
fixed wiring in accordance with AS/NZS 3000.
•
The appliance shall be installed in accordance with national wiring regulations. The maximum
working pressure is 4.15 MPa. This maximum working pressure shall be considered when connecting
the indoor unit to outdoor unit.
•
Do not touch the switch with wet fingers. Touching a switch with wet fingers can cause electric shock.
•
This appliance can be used by children aged from 8 years and above and persons with reduced
physical, sensory or mental capabilities or lack of experience and knowledge if they have been given
supervision or instruction concerning use of the appliance in a safe way and understand the hazards
involved. Cleaning and user maintenance shall not be made by children without supervision.
•
Wear adequate personal protective equipment (protective gloves, safety glasses,...) when installing,
maintaining or servicing the system.
•
The heat exchanger fins are sharp enough to cut. To avoid injury, wear gloves or cover the fins while
working around them.
•
Do not touch the refrigerant pipes during and immediately after operation as the refrigerant pipes
may be hot or cold, depending on the condition of the refrigerant flowing through the refrigerant
piping, compressor, and other refrigerant cycle parts. Your hands may suffer burns or frostbite if you
touch the refrigerant pipes. To avoid injury, give the pipes time to return to normal temperature or, if
you must touch them, be sure to wear proper gloves.
•
Install drain piping to ensure proper drainage. Improper drain piping may result in water leakage and
property damage.
•
Insulate piping to prevent condensation.
•
Be careful when transporting the product.
•
Do not install the air conditioner or heat pump in the following locations:
○ Where a mineral oil mist or oil spray or vapor is produced, for example, in a kitchen. Plastic parts
may deteriorate and fall off or result in water leakage.
○ Where corrosive gas, such as sulfurous acid gas, is produced. Corroding copper pipes or soldered
parts may result in refrigerant leakage.
○ Near machinery emitting electromagnetic waves. Electromagnetic waves may disturb the operation
of the control system and cause the unit to malfunction.
○ Where flammable gas may leak, where there is carbon fiber, or ignitable dust suspension in the air,
or where volatile flammables such as thinner or gasoline are handled. Operating the unit in such
conditions can cause a fire.
•
Take adequate measures to prevent the outdoor unit from being used as a shelter by small animals.
Small animals making contact with electrical parts can cause malfunctions, smoke, or fire. Instruct
the user to keep the area around the unit clean.
•
Servicing shall be performed only as recommended by the manufacturer and licensed or certified in
their jurisdiction.
•
This air conditioner has been designed for standard air conditioning for human beings. For use in
other applications, please contact your Hitachi dealer or service contractor.
•
The air conditioning system should only be installed by qualified personnel, with the necessary
resources, tools and equipment, who are familiar with the safety procedures required to successfully
carry out the installation.
•
PLEASE READ THE MANUAL AND THE FILES ON THE CD-ROM CAREFULLY BEFORE STARTING WORK ON
THE INSTALLATION OF THE AIR CONDITIONING SYSTEM.
•
Failure to observe the instructions for installation, use and operation described in this documentation
may result in operating failure including potentially serious faults or even the destruction of the air
conditioning system.
•
It is assumed that the air conditioning system will be installed and maintained by responsible
personnel trained for the purpose. If this is not the case, the customer should include all the safety,
caution and operating signs in the native language of the personnel responsible.
