UNIT INSTALLATION
STEP 1:
Deciding ceiling opening size
1.Gird ceiling installation situation (600mmx600mm standard ceiling):
● Because this unit is a mini-cassette, there is no need to make an
opening cut on the ceiling, just remove one piece of ceiling panel.
● Under this installation condition, decoration paner 625mmx625mm
is recommended.
2.Hard ceiling installation situation:
● Create the ceiling opening required for installation, below shows
the relationship of the ceiling opening to unit and the panel. (Fig 3)
● Under this installation situation, decoration panel 725mmX725mm
is recommended.
● The maximum ceiling opening size is 680mm. Pay attention that
there must be an overlapping between panel and ceiling. (Fig 3-2)
STEP 2:
Installing the indoor unit
A Installing the unit body
1. Use installation template (supplied with the panel) when deciding the
suspension bolt position (Fig 4). Fig 5 and table 1 show the dimensions
relationship.

2.Piping and wiring must be prepared before hand inside the ceiling when suspending
the unit.
3.The length of suspension bolts must be appropriate for a distance between the
bottom of the bolt and the bottom of the unit of more than 15mm as shown in Fig 6.
4.In order to prevent a possible looseness, it is recommended to use 3 hexagonal
nuts (Prepared on site) and 2 washers (accessory) for each suspension bolt. Pay
attention that 2 nuts will be used in the lower side.(Fig 7)
5.Adjust the distance between the unit and the ceiling bottom to 10~12mm. Tighten all
the nuts on the suspending bolts.(Fig 7)
