“Warning" items are especially important since they can lead to death or serious injury if not followed closely. Under certain
conditions, the "Caution" items can also lead to accident or injury if they are not followed. Therefore, be sure to observe all
ENGLISH
safety precautions listed here.
∆ This symbol means be careful when doing this procedure or touching this equipment.
ᴏ This symbol indicates a prohibited action.
• This symbol means that an action must be taken; the action will be listed next to the symbol.
After the repair work is complete, be sure to conduct a test operation to ensure that the equipment operates properly;
explain the safety precautions for operating the equipment to the customer.
Warning
Disconnect the power cable from electrical supply
before disassembling equipment for repair.
If the refrigerant discharges during the repair work,
DO NOT touch the discharging refrigerant. The
refrigerant can cause frostbite.
Before disconnecting the suction or discharge
pipe of the compressor at the brazed connections,
recover the refrigerant in a well-ventilated area. If
refrigerant remains inside the compressor, the
refrigerant or the refrigerating machine oil will
discharge when the pipe is disconnected and may
cause injury.
If the refrigerant leaks during the repair work,
ventilate the area. The refrigerant can generate
toxic gases when it contacts ames.
The step-up capacitor supplies high-voltage
electricity to the electrical components of the
outdoor unit. Be sure to discharge the capacitor
completely before conducting repair work. A
charged capacitor can cause electrical shock.
Be sure to use parts listed in the service parts
of the applicable model and appropriate tools to
conduct repair work. Never attempt to modify
the equipment. The use of inappropriate parts or
tools can cause electrical shock, excessive heat
generation, or re.
When relocating the equipment make sure that
the new installation site has sufficient strength to
withstand the weight of the equipment. If the new
installation site does not have sucient strength
and if the installation work is no
securely, the equipment can fall and cause injury.
t conducted
Be sure to install the product correctly by using the
standard installation frame provided. Incorrect use
of the installation frame and improper installation
can cause equipment to fall, resulting in injury.

SAFETY OVERVIEW
Read These Safety Precautions
Be sure to use the specied 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 o 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 re.
Do not damage or modify the power cable.
Damaged or modied power cables can cause
electrical shock or re. Placing heavy items on the
power cable and heating or pulling the power cable
can damage the cable.
Do not introduce air into the refrigerant system. If
air enters the refrigerant system, an excessively
high pressure results, causing equipment damage
and injury.
If the refrigerant leaks, be sure to locate the leak
and repair it before charging the system with
additional 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 from leaking into the room.
The refrigerant itself is harmless, but it can
generate toxic gases when it contacts a heat
source such as another appliance or an open flame.
When replacing the remote control battery, be
sure to safely dispose of the battery.
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 re.
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 oor.
ENGLISH
Replace power cables and lead wires if they are
scratched or deteriorated. Damaged cable and
wires can cause electrical shock, excessive heat
generation, or re.
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 re.
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 a water leak
from indoor unit and could cause property damage.

Step 3 - Leak Test and Evacuation
Leak Test
Hazard of Explosion! Never use an open flame to detect
refrigerant leaks.. Explosive conditions may occur. Use a leak
test solution or other approved methods for leak testing.
Failure to follow recommended safe leak test procedures
could result In death or serious injury or equipment or
property damage.
Use only dry nitrogen with a pressure regulator for
pressurizing unit. Do not use acetylene, oxygen or
compressed air or mixtures containing them for pressure
testing. Do not use mixtures of a hydrogen containing
refrigerant and air above atmospheric pressure for pressure
testing as they may become flammable and could result in
an explosion. Refrigerant used as a trace gas should only be
mixed with dry nitrogen for pressurizing units. Failure to
follow these recommendations could result in death or
serious injury or equipment or property damage.
Step 2.3
Step 3.1 Step 3.2
3.1
Step - 3.1
Using a tank of nitrogen with attached regulator, charge the
system with 150 PSIG of dry nitrogen. Use adapter AD-87
(field supplied) to connect to the service valve. Check for
leaks at the flare fittings using soap bubbles or other
detection methods. If a leak is detected, repair and recheck.
If no leaks are detected, proceed to evacuate the system.
