Select the ∗H dimension such that a downward slope of at least 1/100 is ensured as indicated in
"9.5 Drain Piping and Water Supply Work".
[PRECAUTION]
•
Install the indoor and outdoor units, power supply wiring and connecting wires at least 1 meter away from
televisions or radios in order to prevent image interference or noise. Depending on the radio waves, a
distance of 1 meter may not be sufficient enough to eliminate the electric noise.
•
The bellows may not be able to be used in some disctricts, so exercise caution.
(Contact your local government office or fire department for details.)
•
When discharging exhaust air to a common duct, the Building Standard Law requires the use of fire-
proof materials, so attach a 2 m copper plate standing duct or smoke back flow prevention damper.
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 follow. Refer to it to check for points requiring reinforcing.)

Preparations before Installation

1. Confirm the positional relationship between the unit and suspension bolts. (Refer to Fig. 2)
Leave space for servicing the unit and include inspection hatches. (Always open a hole on the side of
the electric parts box so that the air filters, heat exchange elements, fans, and humidifier elements can
easily be inspected and serviced.)

2. Make sure the range of the unit's external static pressure is not exceeded.
(See the fan-strength and static performance characteristic drawings 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 refrigerant, drain
piping, transmission wiring, and remote controller wiring to the unit's piping and wiring holes.
See "9.5 Drain Piping and Water Supply Work", "9.6 Refrigerant Piping Work", and
"9.9 Wiring Example and how to set the Remote Controller".
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.
