Precautions
Instal the drain raising pipes at a height of less than 310 mm.
Install the drain raising pipes at a right angle to the indoor unit
and no more than 300 mm from the unit.
NOTE
The incline of attached drain hose should be
75 mm or less so that the drain socket does not
have to stand additional force.
To ensure a downward slope of 1:100, install
hanging bars every 1 to 1.5 m.
If unifying multiple drain pipes, install the pipes as
shown in
figure
whose gauge is suitable for the operating capacity
of the unit.

General instructions
All field supplied parts and materials and electric works must
conform to local codes.
Use copper wire only.
Follow the "Wiring diagram" attached to the unit body to wire the
outdoor unit, indoor units and the remote controller. For details
on hooking up the remote controller, refer to the "Installation
manual of the remote controller".
All wiring must be performed by an authorized electrician.
A circuit breaker capable of shutting down power supply to the
entire system must be installed.
This system consists of multiple indoor units. Mark each indoor
unit as unit A, unit B..., and be sure the terminal board wiring to
the outdoor unit and BS unit are properly matched. If wiring and
piping between the outdoor unit and an indoor unit are
mismatched, the system may cause a malfunction.
