Outdoor Unit Installation
Outdoor Unit Installation Instructions
Step 1: Select installation location.
The outdoor unit should be installed in the
location that meets the following requirements:
Place the outdoor unit as close to the indoor
unit as possible.
Ensure that there is enough room for
installation and maintenance.
The air inlet and outlet must not be
obstructed or exposed to strong wind.
Ensure the location of the unit will not be
subject to snowdrifts, accumulation of leaves
or other seasonal debris. If possible, provide
an awning for the unit. Ensure the awning
does not obstruct airflow.
The installation area must be dry and well
ventilated.
There must be enough room to install the
connecting pipes and cables and to access
them for maintenance.
The area must be free of combustible gases
and chemicals.
The pipe length between the outdoor and
indoor unit may not exceed the maximum
allowable pipe length.
If possible, DO NOT install the unit where it
is exposed to direct sunlight.
If possible, make sure the unit is located far
away from your neighbors’ property so that
the noise from the unit will not disturb them.
If the location is exposed to strong winds (for
example: near a seaside), the unit must be
placed against the wall to shelter it from the
wind. If necessary, use an awning.
(See Fig. 5.1 & 5.2)
Install the indoor and outdoor units, cables
and wires at least 1 meter from televisions or
radios to prevent static or image distortion.
Depending on the radio waves, a 1 meter
distance may not be enough to eliminate all
interference.

Step 2: Install outdoor unit.
Fix the outdoor unit with anchor bolts (M10)
>60cm / 23.6”
Fix with bolts
CAUTION
• Be sure to remove any obstacles that
may block air circulation.
• Make sure you refer to Length
Specifications to ensure there is
enough room for installation and
maintenance.

- Drainpipe installation 15
- All field piping must be completed by a licensed technician and must comply with the local and national regulations when the air conditioner is installed in a small room measures must be taken to prevent the refrigerant concentration in the room from exceeding the safety limit in the event of refrigerant leakage if the refrigerant leaks and its concentration exceeds its proper limit hazards due to lack of oxygen may result when installing the refrigeration system ensure that air dust moisture or foreign substances do not enter the refrigerant circuit contamination in the system may cause poor operating capacity high pressure in the refrigeration cycle explosion or injury ventilate the area immediately if there is refrigerant leakage during the installation leaked refrigerant gas is both toxic and ammable ensure there is no refrigerant leakage after completing the installation work 17
- Ensure that the length of the refrigerant pipe the number of bends and the drop height between the indoor and outdoor units meets the requirements shown in table 7 17

- Charging with unsuitable substances may cause explosions or accidents ensure that the appropriate refrigerant is used refrigerant containers must be opened slowly always use protective gear when charging the system 25
- Do not exceed the maximum allowable quantity of refrigerant or overcharge the system doing so can damage the unit or impact it s functioning 25
- Do not mix refrigerants types 25
- Liquid side diameter 25
- Note on adding refrigerant 25
- Refrigerant charging must be performed after wiring vacuuming and the leak testing 25
- Some systems require additional charging depending on pipe lengths the standard pipe length varies according to local regulations for example in north america the standard pipe length is 7 m 25 in other areas the standard pipe length is 5m 16 the additional refrigerant to be charged can be calculated using the following formula 25
