3.2.12 Selection of Location
This unit, both indoor and outdoor, is suitable for installation in a commercial and light industrial
environment. If installed as a household appliance it could cause electromagnetic interference.
The VRV outdoor units should be installed in a location that meets the following requirements:
1. The foundation is strong enough to support the weight of the unit and the floor is flat to
2. The space around the unit is adequate for servicing and the minimum space for air inlet and
3. There is no danger of fire due to leakage of inflammable gas.
4. Ensure that water cannot cause any damage to the location in case it drips out the unit (e.g.
5. The piping length between the outdoor unit and the indoor unit may not exceed the allowable
6. Select the location of the unit in such a way that neither the discharged air nor the sound
7. Make sure that the air inlet and outlet of the unit are not positioned towards the main wind

Installation
For Patterns 1 and 2 in figure :
• Wall height for front side no higher than
1500 mm.
• Wall height on the suction side no higher
than 500 mm.
• Wall height for sides – no limit.
If this height is exceeded, calculate h1
and h2 shown in the figure below, and
add the service space for the front
and suction sides to h1/2 and h2/2.
h1 = A (Actual height) – 1500
h2 = B (Actual height) – 500
