Penetrations
Ⓐ Sleeve
Ⓑ Heat insulating material
Ⓒ Lagging
Ⓓ Caulking material
Ⓔ Band
Ⓕ Waterproofing layer
Ⓖ Sleeve with edge
Ⓗ Lagging material
Ⓘ Mortar or other incombustible caulking
Ⓙ Incombustible heat insulation material
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 incom-
bustible 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 guid-
ance of each electric power company.
-
Install the Outside 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 Outside Unit.
- Give some allowance to wiring for electrical part box of Indoor and
Outside Units, because the box is sometimes removed at the time of
service work.
- Never connect the main power source to terminal block of communi-
cation cable. If connected, electrical parts will be burnt out.
- Use 2-core shield cable for communication cable.(O mark in the figure
below) If communication cable of different systems are wired with
the same multiplecore cable, the resultant poor transmitting and re-
ceiving will cause erroneous operations. ( mark in the figure
below)
- Only the communication cable specified should be connected to the
terminal block for Outside Unit communication.
CAUTION
Be sure to correct the outside 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.
!
WARNING
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 defi-
ciency, it may cause an electric shock or fire.
