Safety Precautions
The following safety precautions must be taken when installing the unit.
 R410A refrigerant is used for MINI DVM air conditioner.
- When using R410A, moisture or foreign substances may affect to the capacity and reliability of
the product. Safety precautions must be taken when installing the refrigerant pipe.
- The design pressure of the unit is 4.1MPa. Select appropriate material and thickness according
to the regulations.
- R410A is a quasi-azeotrope of two refrigerants.
Make sure to charge liquid one when adding 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 only the indoor units fit on 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.)

WARNING 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 manufacturer or its service agent or a similar 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 similarly qualified persons according to national
wiring regulations and use only rated cable.
- If the capacity of the power cable is insufficient or electric work is not properly completed, 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 you install the air conditioner in a small room, you consider a proper ventilation to prevent a
leakage level within the maximum permissible limit.
- In that case, you may die from suffocation by some possibility.
 Use only rated parts and tools.
- If you don’t use the rated parts and tools, it can cause trouble with the air conditioner and bring
about 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 to prepare against strong wind or earthquake.
- If the outdoor unit is not properly fixed, it turns over and accidents may occur.
 Install the cables with supplied cables firmly. Fix them securely so that external force is not exerted to
the terminal board.
- If the connection or fixing is incomplete, it can cause trouble with a heat generation, electric shock or
fire and so on.
 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 separate MCCB and ELB when installing the power cable.
- 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.
 If any gas or impurities except R410A refrigerant come into the refrigerant pipe, serious problem may
occur and it may cause injury.
 Make sure 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.

CAUTION 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 remodeled duct as you please.
- The capacity of the air conditioner may reduce, electric shock or fire may occur and it has a chance of
occurrence of and accident like electric shock or fire.
 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 power cable and communication cable of the indoor and outdoor unit at least 1m away
from electric appliances.
- Noise may heard depending on the electric wave though the cables are installed away from
electric appliances.
 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
There is a chance that parts may get damaged due to burned resin.
The capacity 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, carbon fiber or flammable dust
The place where thinner or gasoline is handled.
