SELECTING INSTALLATION SITE

CAUTION
• When moving the unit during or after unpacking, make sure
to lift it by holding its hanger brackets. Do not exert any
pressure on other parts, especially duct connecting flange.
• Attach additional thermal insulation material to the unit body
when it is believed that the temperature and the relative
humidity in the ceiling exceed 86°F and 80%.
Use glass wool, polyethylene foam, or similar with a thickness
of 7/8 in. or more as thermal insulation material.
(1)Select an installation site where the following conditions
are fulfilled and that meet with your customer's approval.
• Install in a place which has sufficient strength and sta-
bility. (Beams, ceiling and other locations capable of
fully supporting the weight of the unit.)
Insufficient strength is dangerous. It may also cause
vibration and unusual operating noise.
• Where nothing blocks air passage.
• Do not install the unit directly against a ceiling or wall.
(If the unit is in contact with the ceiling or wall, it can
cause vibration.)
• Where sufficient clearance for maintenance and service
can be ensured.
[PRECAUTION]
• Install the unit, power supply wiring and transmission
wiring at least 40 in. away from televisions or radios in
order to prevent image interference or noise. (Depend-
ing on the radio waves, a distance of 40 in. may not be
sufficient enough to eliminate the electric noise.)
• The bellows may not be used in some districts, so exer-
cise caution. (Contact your local government office or
fire department for details.)
(2)Use suspension bolts for installation. Check whether
the ceiling is strong enough to support the weight of
the unit or not. If there is a risk, reinforce the ceiling
before installing the unit.
(Installation pitch is mentioned as follows. Refer to it to
check for points requiring reinforcing.)
4. PREPARATIONS BEFORE
INSTALLATION
(1)Confirm the positional relationship between the unit
and suspension bolts. (Refer to figure 1)
Leave space for servicing the unit and include an inspection
hatch. (Always open a hole on the side of the control box so
that the air filters, heat exchanger cores and fans can be
easily inspected and serviced.)
(2)Make sure the range of external static pressure is not
exceeded.
(See the fan speed and static pressure performance charac-
teristic drawing as well as the general catalog for the range
of the external static pressure setting.)
(3)Open the installation hole. (Pre-set ceilings)
• Once the installation hole is opened in the ceiling where
the unit is to be installed, pass transmission wiring and
remote controller wiring to the unit's wiring hole.
See "8-2 WIRING EXAMPLE".
• After opening the ceiling hole, make sure ceiling is level if
needed. It might be necessary to reinforce the ceiling
frame to prevent shaking.
Consult an architect or carpenter for details.
