2 OUTDOOR UNIT INSTALLATION
2.1 Before Installation
After receiving the machine, please check for any transport damage. If finding any surface or internal damage, please
immediately report to the transport company or equipment company in writing.
After receiving the machine, please check the unit and accessories in reference to the packing list. Ensure that the model
is correct and the machine is in good condition. Please also check if the specification and quantity of accessory parts are
correct.
Determine the correct handling route and methods, thus to avoid damaging the unit or causing possible hazard. For the sake
of protection and safety, it is suggested to move the unit with the packaging box. Even though it is not permitted to do like
this under special occasions, do not remove the packaging box, thus to avoid loosening or falling during handling.
Confirm if the installing foundation is solid. When this unit is to be installed on the metal section of the building, make sure
that the electrical insulation must comply with applicable standards.
Ensure that the place of installation is far from the area where the inflammable or explosive substances are stored, thus to
avoid possible explosion or fire due to leakage.
2.2 Installation Site
WARNING!
1. Install the unit where it will not be tilted by more than 5°.
2. During installation, if the outdoor unit has to be exposed to strong wind, it must be fixed securely.
If possible, do not install the unit where it will be exposed to direct sunlight. (If necessary, install a blind that does not
interfere with the air flow.)
1. Install the outdoor unit in a place where it will be free from being dirty or getting wet by rain as much as possible.
2. Install the outdoor unit where it is convenient to connect with the indoor unit.
3. Install the outdoor unit where the condensate water can be drained out freely during heating operation.
4. Do not place animals and plants in the path of the warm air.
5. Take the air conditioner weight into account and select a place where noise and vibration are small.
6. Install the outdoor unit where is capable of withstanding the weight of the unit and generates as less noise and vibration
as possible.
7. Provide the space shown in Figure 3-2-1, so that the air flow is not blocked. Also for efficient operation, leave three of four
directions of peripheral constructions open.

2.3 Caution for Installation
The outdoor unit shall be so installed that the air discharged out of the outdoor unit will not flow back
and that enough space shall be maintained around the machine for repair;
The installing position shall be in good ventilation, so that the machine can breathe and exhaust
enough air. Ensure that there is no obstruction at the inlet and outlet of the machine. If any, please remove
the obstructions blocking the air inlet and outlet.
If the outdoor unit is installed on concrete or solid ground, it shall be fixed by using M10 bolts and nuts.
And ensure that the machine is kept vertical and horizontal.
The outdoor unit must be lifted by using the designated lift hole. During lifting, take care to protect the
air conditioner and avoid knocking the metal parts, thus to prevent rusting in the future.
To meet the noise and vibration requirements, the outdoor unit shall be installed by using rubber
damping pad or spring damper.
To install the drainage pipe, please insert the drainage joint to the drainage hole on the outdoor
chassis and connect a drainage pipe on the drainage joint. (The installing height of outdoor unit shall be at
least 5cm (2inch) if drainage joint is to be used).
To insert the pipe through the wall, the wall-cross tube must be installed.
The installing dimension shall comply with the installation requirements in these instructions. The
outdoor unit must be fixed at the installing position.
The installation shall be done by specialist technicians.
