Introduction
Installation of outdoor units
Determination of the Installation Location
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 prevent vibration and noise generation.
2.
The space around the unit is adequate for servicing and the
minimum space for air inlet and air outlet is available. (Refer to
below figure and choose one of both possibilities.)
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 of the unit (e.g. in case of a blocked drain pipe).
5.
The piping length between the outdoor unit and the indoor unit
may not exceed the allowable piping length. (See “Example of
connection”.)
6.
Select the location of the unit in such a way that neither the
discharged air nor the sound generated by the unit disturb
anyone.
7.
Make sure that the air inlet and outlet of the unit are not
positioned towards the main wind direction. Frontal wind will
disturb the operation of the unit. If necessary, use a windscreen to
block the wind.
8.
Locations where there is mineral oil or kitchens and other
locations where oil may splatter or there may be a lot of steam in
the air. Deterioration of resin parts may cause parts to fall or leak.
9.
Locations where corrosive gases are present, such as sulfuric gas.
This may cause corrosion of copper pipes and brazed parts,
causing the refrigerant to leak.
10. Locations with machinery which gives off electromagnetic waves.
Such waves may cause the control system to malfunction and
prevent normal operation.
