When filling a gap with mortar, cover the penetration part with steel plate so
that the insulation material will not be caved in. For this part, use
incombustible materials for both insulation and covering. (Vinyl covering
should not be used.)

Caution
- Follow ordinance of your governmental organization for technical
standard related to electrical equipment, wiring regulations and
guidance of each electric power company.
- Install the Outdoor Unit communication cable away from the power
source wiring so that it is not affected by electric noise from the power
source. (Do not run it through the same conduit.)
- Be sure to provide designated grounding work to Outdoor Unit.
- Give some allowance to wiring for electrical part box of Indoor and
Outdoor Units, because the box is sometimes removed at the time of
service work.
- Never connect the main power source to terminal block of
communication cable. If connected, electrical parts will be burnt out.
- Use the 2-core shielded wires for communication cable.( mark in
the figure below) If communication cable of different systems are
wired with the same multiplecore cable, the resultant poor
transmitting and receiving will cause erroneous operations. ( mark
in the figure below)
- Only the communication cable specified should be connected to the
terminal block for Outdoor Unit communication.
Be sure to correct the outdoor unit to earth. Do not connect ground
wire to any gas pipe, liquid pipe, lightening rod or telephone earth
line. If earth is incomplete, it may cause an electric shock.
Be sure to have authorized electrical engineers do the electric
work using special circuits in accordance with regulations and this
installation manual.
If power supply circuit has a lack of capacity or electric work
deficiency, it may cause an electric shock or fire.
