CAUTIONS ON INSTALLATION

5. 

Before installation, confi rm the strength and levelness of the 

• 

foundation so that vibrations and noise are not generated.
Fix the outdoor unit securely on a rigid base with foundation 

• 

bolts as shown in the foundation drawing below.
(Prepare 4 sets of commercially available M12-type or 
equivalent foundation bolts, nuts and washers.)
Use resin washers to prevent the paint from being scratched 

• 

off and rusting.
The foundation bolts should be protruded by 15/16 in.

•

Drain treatment

〉〉

In a location where drain from the outdoor unit may cause 

• 

troubles (for example, where drainage may splash on gen-
eral passersby), perform the drain piping work using the 
drain plug (optional).
For drain treatment, space of at least 4 in. is required under 

• 

the bottom frame of the outdoor unit.
In the drain piping work, make sure that drainage is dis-

• 

charged securely.
(When routing the piping downward, check for water leak-
age.)
