WARNING

IT IS ESSENTIAL THAT THE FANS AND HEATERS BE INSPECTED PERIODICALLY TO ENSURE THAT THEY CAN SPIN FREELY AND HAVE NOT BECOME CLOGGED WITH DIRT, POLLEN, OR BY ANIMALS. THIS IS ESPECIALLY TRUE OF THE EXTERNAL CASE FAN AND FAN SHROUD.

WARNING

IN COLD CLIMATES THE FREEZE PROTECTION SYSTEMS MUST BE CORRECTLY INSTALLED AND FULLY FUNCTIONAL AT ALL TIMES. HUMIDIFIER WARRANTY DOES NOT COVER DAMAGE RESULTING FROM FREEZING OF THE HUMIDIFIER, SUPPLY LINES, DRAIN LINES, OR STEAM DISTRIBUTION SYSTEM.

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.

WARNING

IN COLD CLIMATES THE FREEZE PROTECTION SYSTEMS MUST BE CORRECTLY INSTALLED AND FULLY FUNCTIONAL AT ALL TIMES. HUMIDIFIER WARRANTY DOES NOT COVER DAMAGE RESULTING FROM FREEZING OF THE HUMIDIFIER.

D.SERVICING ELECTRODE STEAM CYLINDER

(1)The cylinders inside of the NH electrode stream models have a finite life and must be replaced periodically. The life span of the cylinder varies based on incoming water conditions. The unit will indicate that it is time to change the cylinder by way of a message displayed on the screen. The humidifier should be frequently monitored ensure that the cylinder is changed when required to eliminate downtime. An optional Remote Fault Indication Package (P/N: 2522170) is
