Safety Considerations
1. Safety Considerations
Read these SAFETY CONSIDERATIONS carefully before
repairing air conditioners and heat pumps. After completing
repairs, check if the unit operates properly. All electrical
repairs and work must be carried out by qualified personnel
in accordance local, state, and national regulations. Follow
all instructions that are listed under each hazard sign
(DANGER , WARNING, CAUTION, NOTE) as they are
important for ensuring safety.
DANGER .............. Indicates an imminently hazardous
situation which, if not avoided, will
result in death or serious injury.
WARNING ............ Indicates a potentially hazardous
situation which, if not avoided, could
result in death or serious injury.
CAUTION ............. Indicates a potentially hazardous
situation which, if not avoided, may
result in minor or moderate injury. It
may also be used to alert against
unsafe practices.
NOTE ................... Indicates situations that may result
in equipment or property-damage
accidents only.
1.1 During Repairs
• Do not start or stop the air conditioner or heat pump
operation by plugging or unplugging the power cord.
Plugging or unplugging he power cord to operate or
disconnect the equipment could cause an electrical
shock or fire.
• Wear a safety helmet, gloves, and a safety belt when
working at an elevated height of more than 6.5ft (2m).
Insufficient safety measures could cause a fall
resulting in a injury.
• Use only pipes, flare nuts, tools, and the other
materials designed specifically for R410A refrigerant
systems. Never use tools or materials designed for
R22 refrigerant systems on an R410A refrigerant
system. Doing so could cause a serious accident or
an equipment failure.
• If the installation platform or frame has corroded,
have it replaced. A corroded platform or frame could
cause electrical shock or fire.
• When relocating equipment, make sure that the new
installation site has sufficient strength to withstand
the weight of the equipment. If the installation site
does not have sufficient strength and if the
installation work is not conducted securely, the
equipment could fall and cause injury.
• Disconnect power before disassembling the
equipment for repairs. Working on the equipment
that is connected to a power supply could cause an
electric shock. If it is necessary to supply power to
the equipment to conduct repairs or to inspect the
circuits, do not touch any electrically charged
sections of the equipment.
• Prior to disconnecting the suction or discharge pipe
of the compressor at welded sections, pump-down
the refrigerant gas completely. If there is gas or oil
remaining inside the compressor, the refrigerant gas
or oil can discharge when the pump is being
disconnected and it could cause an injury.
• If refrigerant gas is discharges during repair work,
do not touch the discharged refrigerant gas. The
refrigerant gas could cause frostbites.
• If refrigerant gas leaks during repair or service,
ventilate the area immediately. Refrigerant gas could
produce toxic gas if it comes into contact with
flames.
• The step-up capacitor supplies high-voltage
electricity to the electrical components of the
outdoor unit. Discharge the capacitor completely
before conducting repair work. A charge capacitor
could cause an electrical shock.
• When relocating equipment, keep the refrigerant
circuit free from all substances other than the
specified refrigerant, such as air. Any presence of
air or other foreign substance in the refrigerant
circuit could cause an abnormal pressure rise or
rupture, resulting in injury.
• Check the unit foundation for damage on a continual
basis, especially if it has been in use for a long time.
If left in a damaged condition, the unit could fall and
cause injury.
• Do not repair the electrical components with wet
hands. Working on the equipment with wet hands may
cause an electrical shock.
• Do not clean the air conditioner or heat pump by
splashing water on it. Washing the unit with water may
cause an electrical shock.
• Equipment must be grounded when carrying out
repairs in a humid or wet place to avoid electrical
shocks.
• Turn off the power when cleaning the equipment to
prevent internal fans (that rotate at high speed) from
starting suddenly, as they may cause injury.
• Do not tilt the unit when removing it. The condensate
water inside the unit may spill and wet furniture and
floors.
Safety Considerations vii
Safety Considerations
• Do not touch the refrigerant pipes during and
immediately after operation for any repair work as
the refrigerant pipes may be hot or cold, depending
on the condition of the refrigerant flowing through
the refrigerant piping, compressor, and other
refrigerant cycle parts. Your hands may suffer burns
• All welding and cutting operations must be done in a
well-ventilated place. Welding and cutting
operations done in an enclosed room may cause
deficiency in oxygen in the enclosed room.
• Dismantling of the unit, disposal of refrigerant, oil,
and additional parts, should be done in accordance
with the relevant local, state, and national
regulations.
1.2 After Repairs
• Use an exclusive power circuit for the equipment.
Insufficient circuit amperage capacity could cause
an electrical shock or fire.
• Use specified cable to connect indoor and outdoor
units. Make the connections securely, and route the
cable properly so that there is no force pulling the
cable a the connection terminals. Improper
connections could cause excessive heat generation
or fire.
1.3 Inspections after Repairs
• If the unit has a power cable plug and it is dirty, clean
the plug before securely inserting it into a power
outlet. If the plug has a loose connection, tighten it or
it could cause electrical shock or fire.
• If the power cable and lead wires have scratches or
are deteriorated, replace them. Damaged cable and
wires could cause an electrical shock, excessive
heat generation, or fire.
• Do not use a joined power cable or extension cable,
or share the same power outlet with other electrical
appliances as it could cause an electrical shock,
excessive heat generation, or fire.
• Check if parts and wires are mounted and connected
properly and if the connections at the soldered or
crimped terminals are secure. Improper installation
and connection could cause and electrical shock,
excessive heat generation, or fire.
• Measure the insulation resistance after the repair.
The resistance must be 1M or higher. Faulty
insulation could cause an electrical shock.
• Securely fasten the outdoor unit terminal cover
(panel). If the terminal cover/panel is not fastened
properly, dust or water could enter the outdoor unit
causing fire or electric shock.
• Do not damage or modify the power cable. Damaged
or modified power cables could cause an electrical
shock or fire. Placing heavy items on the power
cable could damage the cable.
• Do not charge air or gas other than the specified
refrigerant to the refrigerant system. If air enters the
refrigerant system, it could cause excessive high
pressure resulting in equipment damage and injury.
• If refrigerant gas leaks, locate the leaking point and
repair it before charging refrigerant. After charging
the refrigerant, check for refrigerant leaks. If the
leaking pint cannot be located and the repair work
must be stopped, perform a pump-down. Close the
service valve to prevent the refrigerant gas from
leaking into the room. the refrigerant gas itself is
harmless, but it could generate toxic gases if it
comes into contact with flames.
• After replacing the battery in the remote controller,
dispose of the old battery to prevent children from
swallowing it. If a child swallows the battery, consult
with a doctor immediately.
• Check the drainage of the indoor unit after the repair.
Faulty drainage may cause the water to enter the
room resulting in wet floors and furniture.
1.4 Safety for Users
• Never attempt to modify the equipment. Doing so will
cause electrical shock, excessive heat generation, or
fire.
• Never remove the fan guard of the unit while the unit
is operating. A fan rotating at high speed without the
fan guard is very dangerous.
• Before cleaning the unit, stop the operation of the
unit by turning the power off or by pulling the power
cord out from its socket. Otherwise, an electrical
shock or injury may result.
• Do note wipe the controller operation panel with
benzene, thinner, chemical dust cloths, or similar.
The panel may get discolored or the coating can peel
off. if it is extremely dirty, soak a cloth in a waterdiluted neutral detergent, squeeze it well, and wipe
the panel clean. Then wipe it with another dry cloth.
