5.2. Attaching the duct connecting

flanges

Use the screws supplied to secure the duct connecting flanges to the
Fresh Master.

Caution:

Before attaching the duct connecting flanges, check that no
foreign matter (scraps of paper, vinyl, etc.) has found its way
inside the main unit.

Replace the screws that were removed when the duct connect-
ing flange was removed back in place and securely tighten them.

5.3. Hanging the unit body

1. Hang the ceiling suspension fixtures on the hanging bolts and ad-

just in such a way that the main unit is level.

2. Tighten up securely using double nuts in order to prevent looseness.

Caution:

When suspending the main unit from the ceiling, do not handle
it in such a way that force will be applied to the control box.

Fasten the body so that it is oriented horizontally. (within 1˚)

5.4. When changing the direction of

the out door side duct (EA/OA)

Remove the flange cover and suspension fixture.

1. Remove the four mounting screws for the flange cover and remove

the flange cover.

2. Remove the screws at the top mounting position.

3. Remove the ceiling suspension fixtures and attach them at higher

mounting positions.

4. Tighten up the screws in the screw hole where the ceiling suspen-

sion fixtures were removed in order to prevent air leaks.

Mounting the duct connection flange

1. Use the mounting screws provided to mount the duct connection

flange to the main body.

2. Use the four mounting screws that were removed to attach the

flange cover.

5.5. Connecting the ducts

1. Fit the ducts securely into the duct connecting flanges, and wind

aluminium tape available from a field supply around them to pre-
vent air leaks.

2. Suspend the ducts from the ceiling so that their weight will not be

applied to the Fresh Master.

3. The exhaust/outdoor and supply ducts must be covered with heat-

insulating material in order to prevent condensation from forming.

Caution:

The main unit is equipped with connection locations for
equipotential connection of ducts.

Down ward gradient of outdoor duct: 1/30 or more (toward
wall side)

Provision of distance for the exhaust/outdoor ducts in table
below (to prevent rain water from seeping in)

Model

Distance

GUF-50RDH3, GUF-50RD3

1 m or more

GUF-100RDH3, GUF-100RD3

2.5 m or more

Before connecting the ducts, check that no sawdust or any
other foreign matter (scraps of paper, vinyl, etc.) has found its
way inside the ducts.

Do not touch the damper plate inside the main unit when con-
necting the ducts.

Do not install the ducts in the ways illustrated below. Doing
so will reduce the air volume and give rise to abnormal sounds.
