SAFETY INFORMATION
SEVERE WARNING SIGNS
If you don’t follow the safety precautions, you may get the risk of serious wound or death.
The installation must be done by the installer or its service agent or a qualified
person in order to avoid a hazard.
• Installation by an unqualified person may cause a water leakage, electric shock or fire and
so on.
The electric work must be done by service agent or qualified persons according to
national wiring regulations and use only rated cable.
• Use certified power cable in the market suggested here and do electric work according
to installation manual otherwise, electric shock or fire may occur.
Install the outdoor unit correctly according to the installation manual.
• An incorrect installation may cause a water leakage, electric shock or fire and so on.
Manufacturer is not responsible for accidents due to incorrect installation.
When installing the unit in a small room, take measures in order to keep the
refrigerant concentration from exceeding allowable safety limits in the event
of a refrigerant leak.
• Excessive refrigerant concentration in a closed room can lead to oxygen deficiency.
Use certified parts in the market and supplied parts from the factory.
• If you don’t use the certified parts and tools, it can cause trouble to the air conditioner
and bring into injury.
Install the outdoor unit on a hard and even place that can support its weight.
• If the place cannot support its weight, the outdoor unit may fall down and it may cause injury.
Fix the outdoor unit securely on foundation to resist strong wind or
earthquake.
• If the outdoor unit is not properly fixed, it turns over and accidents may occur.
Fix power cable on fixture of outdoor unit securely not to be pulled out by
external force.
• If fixing is incomplete, it can cause trouble with a heat generation, electric shock or fire
and so on.
Before installing an air conditioner, please read this manual thoroughly to ensure that you know how to
safely and efficiently install a new appliance.
 DVM PLUS III HR air conditioner uses R410A refrigerant.
- When using R410A, moisture or foreign substances may affect the capacity and reliability of the product.
Safety precautions must be taken when installing the refrigerant pipe.
- The designing pressure of the system is 4.1MPa. Select appropriate material and thickness according to the
regulations.
- R410A is a quasi-azeotrope of two refrigerants.
Make sure to charge with liquid phase when filling refrigerant.
If you charge gaseous refrigerant, it may affect the capacity and reliability of the product as a result of change
formation of the refrigerant.
 Connect the indoor units for R410A refrigerant. Check whether the indoor units can be connected with the
product’s catalogue. (When incorrect indoor units are connected, they cannot operate normally.)

safety information _03
ENGLISH
Arrange the cables between the indoor and outdoor unit after connecting.
Attach the cover securely so that the electrical component box cover does
not get loosen.
• If the cover is attached incompletely, it can cause trouble with a heat generation, electric
shock or fire of the terminal board.
Install MCCB and ELB according to installation manual.
• If you do not install the MCCB and ELB, electric shock or fire may occur.
The unit must be plugged into an independent circuit if applicable or
connect the power cable to the auxiliary circuit breaker. An all pole
disconnection from the power supply must be incorporated in the fixed
wiring with a contact opening of >3mm(1/8").
If any gas or impurities except R410A refrigerant come into the refrigerant
pipe, serious problem may occur and it may cause injury.
Make sure that there is no leakage after installation.
• Toxic gas may generate when refrigerant gas contacts with fire.
Leak test must be done using only Nitrogen gas.
When the product operates in heat mode during winter time, it operates
protection mode when the outdoor temperature drops below 0°C. Therefore,
supply the power during winter time. If the power is not supplied, compressor
protection mode will not operate and cause product malfunction.
Do not modify the product on your own.
• Potential risk of electric shock, fire, product failure or injury.
CAUTION SIGNS
If you don’t follow the safety precautions, you may get the risk of injury or loss of property.
Make sure of a earthing.
• Do not connect the earth wire to the gas pipe, water pipe, lighting rod or telephone wire.
If earthing is incomplete, electric shock or fire may occur.
Do not connect the heater to the outdoor unit and do not install altered duct
as you please.
• The capacity may reduce, electric shock or fire may occur.
Make sure that the condensed water dripping from the drain hose runs out
properly and insulate the drain pipe so that frost does not generate.
• Household goods may get wet if the drain pipe is not properly installed.
Install the indoor unit away from lighting apparatus using the ballast.
• If you use the wireless remote control, it may not operate normally.
Do not install the air conditioner in following places.
• The place where there is mineral oil or arsenic acid.
Those parts may get damaged due to burned resin.
The efficiency of the heat exchanger may reduce or the air conditioner may be out of
order.
• The place where corrosive gas such as sulfurous acid gas generates from the vent pipe
or air outlet.
The copper pipe or connection pipe may corrode and refrigerant may leak.
• The place where there is a machine that generates electromagnetic waves.
The air conditioner may not operate normally due to control system.
• The place where there is a danger of existing combustible gas, thinner or gasoline is
handled.
• The place where carbon fiber or flammable dust is.
• The place where like spa and shore.

CAUTION SIGNS
Install the power cable and communication cable of the indoor and outdoor
unit at least 1.5m(5') away from the electric appliances and install it at least
2m(6.5') away from the cable from the lightning rod.
• Noise may heard depending on the electric wave though the cables.
Install the outdoor unit within the angle of 25~55˚ depending on the building
height as below table.
Changes in DVM PLUS III HR comparing with conventional models(DVM PLUS II)
• Use R410A refrigerant.
• Check indoor units, distributor kits, etc which are connected with DVM PLUS III HR are
compatible with DVM PLUS III HR or not.
• Version of AVXE/NDA and higher is available.
• Make sure the combination method of outdoor units is different from DVM PLUS II.
• The length of maximum piping, level difference, the quantity of connectable indoor units,
the installation at the outdoor joints and the outdoor unit combinations are different from
the conventional models.
• Outdoor joint of gas side pipe should be installed horizontally due to the combination of
variable units when the height of the main pipe is lower than the outlet of the pipe of the
outdoor unit. The Installation of the liquid pipe and high pressure gas pipe are the same.
• If the pipe length between outdoor units becomes 2m(6.5') or more, install vertical trap
to upstream to prevent oil from getting accumulated in the pipes of the outdoor unit in
case of part load operation with the states which the last outdoor unit stops operating.
