Be sure to use the specified cable to connect
between the indoor and outdoor units. Make the
connections securely and route the cable properly
so that there is no force pulling the cable at the
connection terminals.
When connecting the cable between the indoor and
outdoor units make sure that the terminal cover
does not lift off or dismount because of the cable.
If the cover is not mounted properly, the terminal
connection section can cause an electrical shock,
excessive heat generation, or fire.
Do not damage or modify the power cable.
Damaged or modified power cables can cause
electrical shock or fire. Placing heavy items on the
power cable and heating or pulling the power cable
can damage the cable.
Do not mix air or gas other than the specified
refrigerant (R=4 10A/R22) in the refrigerant system.
If air enters the refrigerant system, an excessively
high pressure results, causing equipment damage
and injury.
If the refrigerant gas leaks, be sure to locate the leak
and repair it before charging the refrigerant. If the
leak cannot be located and the repair work cannot
be stopped, be sure to perform pump-down and
close the service valve to prevent the refrigerant
gas from leaking into the room. The refrigerant gas
itself is harmless, but it can generate toxic gases
when it contacts flames, such as fan and other
heaters or stoves and ranges.
When replacing the remote control battery, be sure
to safely dispose of the battery to prevent children
from swallowing it.
Do not install the equipment in a place where
there is a possibility of combustable gas leaks. If
combustible gas leaks and remains near the unit, it
may cause a fire.
Be sure to install the packing and seal on the
installation frame correctly. If the packing and
seal are not properly installed, water can spill out,
wetting furniture and the floor.
SAFETY OVERVIEW
Read These Safety Precautions
Replace power cables and lead wires if they are
scratched or deteriorated. Damaged cable and
wires can cause electrical shock, excessive heat
generation, or fire.
Check to see if the parts are mounted correctly,
that the wires are connected correctly, and that
connections at soldered or crimped terminals are
secure. Improper installation and connections can
cause excessive heat generation, electrical shock,
and fire.
If the installation platform or frame has deteriorated
or corroded, replace it. Corroded platform or frames
can cause the unit to fall, resulting in injury.
Check to make sure that the equipment is grounded.
Repair it if it is not properly grounded. Improper
grounding can cause an electrical shock.
Be sure to measure the installation resistance of
the repair. Be sure that the resistance is 1 M ohm
or higher. Faulty installation can cause an electric
shock.
Be sure to check the drainage of the indoor unit
after the repair. Faulty drainage can cause the water
to spill, wetting the furniture and the floor.
Indoor Clearances: If noncompliant may lead to temperature
control complaints.
Wire Sizing: If noncompliant may lead to communication errors
and inverter irregular operation.
Splices in Field Wiring: Splices between the wires that connect
between the outdoor and indoor unit should be avoided.
Communication errors may occur if noncompliant.
Sealing Penetrations: If penetrations at back of unit are not
sealed, unconditioned air may be drawn into the back of the
indoor wall mount unit. Temperature control and capacity
complaints may occur.
