4. Selecting an installation site

Select a site with sturdy fixed surface sufficiently durable against
the weight of unit.

Before installing unit, the route to carry the unit to the installation
site should be determined.

Select a site where the unit is not affected by entering air.

Select a site where the flow of supply, return, exhaust and outdoor
air is not blocked.

Select a site where refrigerant piping and exhaust/outdoor ducts
can easily be led to the outside.

Select a site which allows the supply air to be distributed fully in room.

Select a location where the inspection opening can be installed.

Do not install unit at a site with oil splashing or steam in large quantities.

Do not install unit at a site where combustible gas may generate,
flow in, stagnate or leak.

Do not install unit at a site where equipment generating high frequency
waves (a high frequency wave welder for example) is provided.

Do not install unit at a site where fire detector is located at the
supply air side. (Fire detector may operate erroneously due to the
heated air supplied during heating operation.)

When special chemical product may be scatter all around such as
site chemical plants and hospitals, full investigation is required be-
fore installing unit. (The plastic components may be damaged de-
pending on the chemical product applied.)

Do not install this product in a refrigerated warehouse, heated swim-
ming pool or other location where the temperature and humidity
are significantly different.
(Failure to heed this warning may result in electrical shock or mal-
function.)

The electro-magnetic susceptibility has been chosen at a level that
gains proper operation in residential areas, on business and light
industrial premises and on small-scale enterprises, inside as well
as outside of the buildings. All places of operation are character-
ised by their connection to the public low voltage power supply
system.

5. Installing the Fresh Master

5.1. Fixing hanging bolts

(Use M10 or M12 hanging bolts. The bolts and washers should be
supplied in the field.)
(Give site of suspension strong structure.)

Hanging structure

Ceiling: The ceiling structure varies from one building to another.
For detailed information, consult your construction company.

1

Reinforcing the ceiling with additional members (edge beam, etc.)
must be required to keep the ceiling at level and to prevent the
ceiling from vibrations.

2

Cut and remove the ceiling members.

3

Reinforce the ceiling members, and add other members for fixing
the ceiling boards.

Mount the washers (outer diameter of >21 mm for M10, >24 mm
for M12) and nuts obtained from a field supply onto the pre-recessed
hanging bolts (M10 or M12) also obtained from a field supply, as
shown in the figure.

4.1. Install the Fresh Master on a ceiling

strong enough to sustain its weight

Warning:

The unit must be securely installed on a structure that can sus-
tain its weight. If the unit is mounted on an unstable structure, it
may fall down causing injuries.

4.2. Securing installation and service

space

Select the optimum direction of supply airflow according to the con-
figuration of the room and the installation position.

As the piping and wiring are connected at the side surfaces, and
the maintenance is made at the same surfaces, allow a  proper
space properly. For the efficient suspension work and safety, pro-
vide a space as much as possible.
