1 PRECAUTIONS FOR INSTALLATION
1�1 Precautions for Installation
Before installation, please ensure if the installing site, power ratings, possible operating range (pipe distance, height
difference between indoor and outdoor unit, power voltage) and installing space are correct and suitable. The outdoor unit
is general to all models according to its power.
◆
To ensure correct installation, please make sure to read the Safety Considerations thoroughly before starting the
installation works.
◆
The considerations stated below are classified into WARNING and CAUTION. Those that might cause
death or severe injury in case of wrong installation are identied in WARNING. However, those that are stated in
CAUTION may also cause severe accidents sometimes. Therefore, both of them relate to important safety considerations
and must be strictly followed..
◆
After completing the installation and test run and conrming that all are normal, please introduce to the client
on how to use and repair the machine according to the Operating Instructions. Besides, please deliver the considerations
herein to the clients together with the Operating Instructions, and ask them to keep properly.
WARNING!
◆
The installation shall be performed by the vendor or professional dealer from which you buy the machine. If you
install by yourself, any improper installation might cause water leakage, electric shock or re accident.
◆
The installation shall be done correctly according to installation instructions. Improper installation may cause
water leakage, electric shock or re.
◆
To install a large air-conditioning system in a small room, please make sure to take measures to prevent that the
refrigerant will not exceed the limit concentration in case of leakage. For the measures to prevent the refrigerant from
exceeding the limit concentration, please consult your dealer. If no proper measures, it might cause human suffocation in
case of refrigerant leakage.
◆
Please install at a position that is strong enough to support the weight of machine. If the installing position is of
low strength, the machine may drop down and thus cause human injury.
◆
Please carry out installation in accordance with the rules for preventing the typhoon or earthquake. The machine
may tip over if the installation does not comply with the requirements.
◆
The electrical cabling shall be carried out by qualified electricians in accordance with the Safety Code for
Electrical Equipment, relevant local rules and the installation instructions. Make sure to use the special-purpose circuit. If
the power circuit capacity is low or the construction is improper, it might cause electric shock or re accidents.
◆
Please use suitable cables and connect them securely. Please fix the terminal joints securely. The terminal
connection shall not be affected due to any external force applied onto the cable. Improper connection and xing may
cause heating and re accidents.
◆
Keep the cables in correct shape and prevent them from protruding upward. Please protect them securely with
repair board. Improper installation may cause heating and re accidents.
◆
When erecting or relocating the air conditioner, do not let any air enter into cooling circulation system except the
specied refrigerant. If any air is mixed, abnormal high pressure will occur in the cooling circulation system, thus causing
crack or human injury accidents.
◆
During installation, please always use the attached parts or designated parts. Failure to use the designated parts
may cause water leakage, electric shock, re or refrigerant leakage.
CAUTION:
◆
Please earth securely. Do not connect the earth wires to gas pipe, water pipe, lightning rod or telephone line.
Improper earthling might cause electric shock.
◆
Leakage circuit breaker must be installed at some place. No installation of leakage circuit breaker might cause
electric shock.
◆
Do not install at a place where inammable gas might leak. Gas leakage and despot around the machine might
cause re accidents.
◆
To ensure correct drainage of water, the drainage pipe shall be installed according to the installation instructions.
Also the heat insulation shall be provided to avoid condensing. Improper installation of the pipe might result in water
leakage and lead to possible wetting of the articles in the room.
