Operating Considerations
• Earth connection must be available. The absence of earth connection or incomplete earth
connection may cause electric shock. Earth connection must not lead to gas pipe, tapping pipe,
lightning rod or telephone line.
• Creepage breaker must be available. Creepage test must be done after devices are mounted. In
case that creepage breaker is absent, electric shock may take place.
• Parts delivered together with the device or parts particularly designated by us are to be used
during installation lest electric shock and re accident occur.
• Outdoor air duct shall be installed with proper and adequate obliquity to prevent rainwater from
dripping into the device. When incorrectly mounted, rainwater may enter the building and
damage furniture and cause re and electric shock.
• Outdoor pipeline and gas supply lines shall be wrapped with heat insulant to prevent dew
congealment. When incorrectly installed, dew water may drip into the building and damage
furniture.
