C.FREEZE PROTECTION SYSTEM (STANDARD)

(1)Freeze protection is Standard for NH Outdoor units. This system prevents internal water freeze-up, which may damage the humidifier.

(2)The system consists of an additional normally closed mechanical drain valve. This valve is activated by a bi-metallic strip thermostat, which allows for it to operate in the event of a power failure. When the thermostat detects that the water inside the humidifier has cooled to 43°F (6°C), the valve opens allowing water to drain. The freeze protection system drains water from steam cylinders, reservoirs, hoses, and internal lines. Emptying the humidifier protects the hoses, fittings, valves, cylinders, and fill cups from ice damage and prevents unit freeze up.

WARNING

ENSURE THAT THE FREEZE PROTECTION SYSTEM DRAIN HOSE IS FREE OF KINKS OR BLOCKAGES THAT MAY PREVENT IT FROM OPERATING.
