SYSTEM FLOWCHART DIMENSIONAL DRAWING OF BASE

1. Direct Mount 2. Anti-Vibration Mount

When the unit is installed indoors, a syphon (option) should be installed.

If the back pressure of the exhaust-piping extension exceeds 500Pa, use a long syphon and make the height of the base from F.L. to 250mm or more.

Type of Anchor B olt Size Embedded Depth A (mm)

L-type/LA-type

Resin 90

Male screw mechanical 60

Notes: 1 For use of box-out L-type/L A-type bolt.

When l aying the co ncrete for the base, prov ide a box-out for ﬁxing the ancho r bolts, ﬁx the anch or bolts and then secure them in the concr ete.

2 It is sometimes necessary to chang e the thi ckness of the

base depending on the foun datio n stre ngth, so car ry out the work after consulting construction engineers.

3 Earthquake-resistance strength: Horizontal seismic

coef ﬁcient of 0.6 (Numer ic values with * show the dimensi ons in the case of a ho rizontal seismic coef ﬁcient 1.0).

4 When using a sm aller base, join the base and

the structure with reinforcing bars.

INSTALL ATION SPACE

1. Single Unit Installation 2. Multiple Units Installation

Notes

1. When surrounding the unit with soundproof walls, attach openings (louvres or the like) to the

bottom of the soundproof walls. (To prevent the short circuits of radiating air).

2. Decide installation space after consideration of the piping space.

3. If the distance of retention is speciﬁed by local-government ﬁre prevention ordinances and

enforcement regulations, secure the installation space according to these regulations.

4. Give consideration not to cause problems for neighbouring houses due to operating noise,

radiating air, or hot ventilation air.

5. Depending on the situation, the site may be ﬁlled with radiating air and this has an effect on

performance. Prevent the short circuits with the optional wind direction boards, etc.
