SAFETY INFORMATION
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 IV 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 designed maximum 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 vapour refrigerant, it may affect the capacity and reliability of the product as a result of a change in
the blend 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.)
SEVERE WARNING SIGNS
If you don't follow the safety precautions, there may be a risk of injury or death.
The installation must be done by the manufacturer 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.
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 injury.
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 Oxygen Free Nitrogen (OFN) gas.
Use the supplied accessories, specified components and tools for the installation.
• Do not use the pipe and the installation product used for the R22 refrigerant.
• Failure to use the specified components can cause the product fall, water leakage, electrical shock,
and fire. (The pipe and flare components used for R22 refrigerant must not be used)
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.
Check the following before installation and service work.
• Before welding, remove dangerous and inflammable things that may cause an explosion
and fire around the work.
• Before welding, remove the refrigerant from inside the pipe or the product.
- Leakage of the refrigerant in the pipe while welding could make the pressure of the refrigerant
rise causing the pipe to burst. The explosion could cause severe injury to the installer.
• When welding, use the OFN gas to eliminate oxidation inside the pipe.
