Si39-303 Unpacking and Placing the Unit
Installation Manual 165
5. Unpacking and Placing the Unit
!
Make sure the unit is installed level on a sufficiently strong base to prevent vibration and
noise.
!
Secure the unit to its base using foundation bolts. (Use four commercially available M12-
type foundation bolts, nuts, and washers.)
!
The foundation bolts should be inserted 20 mm.
!
Make sure the base under the unit extended more than 765mm behind the unit.
!
The height of the base should be at least 150mm from the floor.
!
The unit must be installed on a solid longitudinal foundation (steel beam frame
or concrete) as indicated in figure below.

2.Depth of product
3.Shape of indoor unit’s support leg and foundation bolt positions
Do not use stands to support the corners
Caution 1. Prepare a water drainage channel around the foundation to drain waste water from around
the unit.
2. If the unit is to be installed on a roof, check the strength of the roof and its drainage facilities
first.
3. If the unit is to be installed on a frame, install the waterproofing board within a distance of
150mm under the unit in order to prevent infiltration of water coming from under the unit.
[Precaution]
!
When installing on a roof, make sure the roof floor is strong enough and be sure to water-
proof all work.
!
Make sure the area around the machine drains properly by setting up drainage grooves
around the foundation.
(Drain water is sometimes discharged from the outdoor unit when it is running.)
!
Block all gaps in the holes for passing out piping and wiring using sealing material (locally
procured). (Small animals may enter the machine.)
