Safety precautions
Please follow the following safety information for safety of the installer and the user.
࢜
DVM S air conditioner uses R-410A refrigerant.
࡛
When using R-410A, moisture or foreign substances may affect the performance and reliability of the
product. Safety precautions must be obeyed when installing the refrigerant pipe.
࡛
The designed maximum pressure of the system is 4.1MPa and therefore select appropriate material
and thickness according to the regulations.

After completing the installation and trial operation, explain to the user how to use and maintain the
product. Also, hand over this installation manual so that it can be stored by the user.
࢜
Manufacturer is not responsible for the incidents occurred by improper installation. Installer is responsible
for any installation related claims from the user occurred by neglecting warnings and cautions stated in
this manual. (Installer will be responsible for any service charges that may occur)
