Please read these “SAFETY CONSIDERATIONS” carefully
before installing air conditioning equipment and be sure to
install it correctly. After completing the installation, make sure
that the unit operates properly during the test operation.
Please instruct the customer on how to operate the unit and
keep it maintained.
Also, inform customers that they should store this installation
manual along with the operation manual for future reference.
This air conditioner comes under the term “appliances not
accessible to the general public”.
SAFETY CONSIDERATIONS1.
Meaning of danger, warning, caution and note symbols.
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 sued to alert against
unsafe practices.
NOTE ..................... Indicates situation that may result in
equipment or property-damage-only
accidents.
DANGER
Refrigerant gas in heavier air and replaces oxygen. A •
massive leak could lead to oxygen depletion, especially
in basements, and an asphyxiation hazard could occur
leading to serious injury or death.
Do not ground units to water pipes, telephone wires or •
lightning rods because incomplete grounding could
cause a severe shock hazard resulting in severe injury
or death, and to gas pipes because a gas leak could
result in an explosion which could lead to severe injury
or death.
Do not install unit in an area where fl ammable materials •
are present due to risk of explosion resulting in serious
injury or death.
If the refrigerant gas leaks during installation, ventilate •
the area immediately.
Refrigerant gas may produce toxic gas if it comes in contact
with fi re such as from a fan, heater, stove or cooking device.
Exposure to this gas could cause severe injury or death.
After completing the installation work, check that the •
refrigerant gas does not leak.
Refrigerant gas may produce toxic gas if it comes in contact
with fi re such as from a fan, heater, stove or cooking device.
Exposure to this gas could cause severe injury or death.
Safely dispose of the packing materials. •
Packing materials, such as nails and other metal or wooden
parts, may cause stabs or other injuries.
Tear apart and throw away plastic packaging bags so that
children will not play with them. Children playing with plastic
bags face the danger of death by suffocation.
WARNING
Ask your dealer or qualifi ed personnel to carry out •
installation work. Do not try to install the machine by
yourself.
Improper installation may result in water leakage, electric
shocks or fi re.
Perform installation work in accordance with this instal- •
lation manual.
Improper installation may result in water leakage, electric
shocks or fi re.
When installing the unit in a small room, take measures •
against to keep refrigerant concentration from exceed-
ing allowable safety limits in the event of refrigerant
leakage.
Contact the place of purchase for more information. Exces-
sive refrigerant in a closed ambient can lead to oxygen
defi ciency.
Be sure to use only the specifi ed accessories and parts •
for installation work.
Failure to use the specifi ed parts may result in water leak-
age, electric shocks, fi re or the unit falling.
Install the air conditioner on a foundation strong •
enough to withstand the weight of the unit.
A foundation of insuffi cient strength may result in the equip-
ment falling and causing injuries.
Carry out the specifi ed installation work after taking •
account of strong winds, typhoons or earthquakes.
Improper installation work may result in the equipment falling
and causing accidents.
Make sure that a separate power supply circuit is pro- •
vided for this unit and that all electrical work is carried
out by qualifi ed personnel according to local laws,
regulations and this installation manual.
An insuffi cient power supply capacity or improper electrical
construction may lead to electric shocks or fi re.
Make sure that all wiring is secured, the specifi ed wires •
are used, and no external forces act on the terminal
connections or wires.
Improper connections or installation may result in fi re.

- English 16
- In the check operation the status of the outdoor unit is checked and incorrect wiring is checked for 16
- Make sure to close the outer panel before leaving the outdoor unit in the power on status to avoid injury always make sure that the circuit breaker on the power supply panel of the installation is switched off before doing any work 16
- Make sure to open the stop valve after fi nishing the piping work operating the air conditioner with the stop valve shut may damage the compressor 16
- Make sure to perform the check operation after installation if the air conditioner is operated using the indoor remote controller without performing the check operation the mal function code u3 is displayed in the indoor remote control ler and normal operation is disabled 16
- Piping size and heat insulation 5 refer to 6 1 selection of piping material 6 5 heat insulation of the piping check of stop valve 6 confi rm that the stop valve is open on both the liquid line and gas line record of amount of additional refrigerant 7 record the amount on the label sticked on the back of the front panel measurement of insulation in main power circuit 8 use the megatester for 500 v do not use any megatester for low voltage electric circuits except 230 v wiring between the outdoor unit and the indoor unit 16

- Warning 16
- After fi nishing the check operation operate the air condi tioner normally heating is not available if the outside air temperature is 75 f or more refer to the operation manual supplied together with the unit confi rm that the indoor and outdoor units are operating normally if a knocking sound is heard in the liquid compression of the compressor stop the air conditioner immediately and energize the crankcase heater for a suffi cient period of time then start the operation again run the indoor unit one by one in turn and confi rm that the corresponding outdoor unit is running check to see if cold or hot air is coming out of the indoor unit press the fan direction button and fan speed control button on the remote controller to see if the fan is operating nor mally 17
- Check a malfunction code in the remote controller connected to the indoor unit 17
- Checks in normal operation 9 2 17
- English 16 17
- If the air conditioner is started within about 12 minutes after the power of the indoor outdoor unit is turned on the h2p indicator lights and the compressor does not run confi rm that the led status is as shown in the table in 2 in 9 1 power on and check operation before starting the air conditioner the air conditioner may require about 10 minutes maximum until it can start the compressor after start of operation this period of time is required to homogenize the refrigerant status and does not indicate any failure the check operation does not provide any means of check ing the indoor units individually for that purpose perform the normal operation using the remote controller after fi nish ing the check operation the check operation is not available in any other mode such as the recovery mode before running a check on the unit changing the indoor remote controller settings might cause the error code uf to be displayed and prevent a proper check to be run 17
- Once stopped the compressor will not start for about 5 minutes even if the on off button on the remote con troller is pressed when the system operation is stopped by the remote con trol the outdoor units may continue to operate for a further 3 minutes if the system has not undergone the check operation by the test operation button since it was fi rst installed a malfunc tion code u3 is displayed in this case perform the check operation by referring to 9 1 power on and check operation 17
