12. Be sure to leave enough space around the outdoor unit to maintain proper performance and to allow access for routine
maintenance.
• Allow enough space from any obstacles as shown in Fig.1.2 below in order to prevent short-circuits from occurring.
(If installing more than one outdoor unit, make the necessary space available as outlined in 14.)
However, there should be at least 1 meter of free space above the unit.
• The height of any obstacles at the air intake and outlet sides should not be greater than the height of the outdoor unit.
13. If installing more than one outdoor unit, allow enough space around each unit as shown below.
• The distance given above are the minimum distance required in order to maintain proper performance.
Allow as much space as possible in order to get the best performance from the units.
10.1.4. Transporting And Installing The Outdoor Unit
• Transporting
1. The outdoor unit should be transported in its original packaging as close to the installation location as possible.
2. If suspending the outdoor unit, use a rope or belt, and use cloth or wood as padding in order to avoid damaging the unit.
• Installation
1. Read the “Selecting the outdoor unit installation location” section thoroughly before installing the outdoor unit.
2. If installing the unit to a concrete base or other solid base, use M10 or W3/8 bolts and nuts to secure the unit, and ensure
that the unit is fully upright and level.
(The anchor bolt positions are shown in the diagram at the right side.)
In particular, install the unit at a distance from the
neighbouring building which conforms to regulations
specified by local noise emission regulation
standards.
3. Do not install the outdoor unit to the building’s roof.
4. If there is a possibility that vibration may be
transmitted to the rooms of the building, place rubber
insulation between the unit and the installation
surface.
5. Drain water will be discharged from the outdoor unit
when operating the system in heating or defrosting
modes. Select an installation location which will allow
the water to drain away properly, or provide a
drainage channel so that the water can drain away.
(If this is not done, the drain water may freeze during
winter, or the water may spill down to areas
underneath the installation location.)
Maintain sufficient space above the unit.
