available to signal remotely that he humidifier requires service. If the NORTEC OnLine option was ordered, cylinder change notices will be delivered via email.
(2)Please refer to the NH Series Indoor Installation guide for further details on replacing cylinders.
E.SERVICING NHRS WITH SCALE MANAGEMENT SYSTEM
(1)As with the indoor units, the scale collector tanks on the NHRS must be emptied periodically based on supply water conditions. At a minimum NORTEC recommends the tanks be emptied twice every year/season. Also, every third time the tanks are cleaned, the cylinder and heating elements should be disassembled and cleaned as well. This will ensure long and reliable operation of your NORTEC humidifier.
(2)The procedure for changing the cylinder is similar to that of the indoor units with two minor differences:
(a)The guide drain control is located on the back of the scale collector tank as opposed to the side.
(b)When the tank has finished draining the hose clamps that secure the freeze protection/ drain hoses to the tank need to be loosened and the hoses removed. With the hoses disconnected the scale collector tank can be removed and emptied. Ensure that the hoses are reconnected and secure before restarting the humidifier.
(c)For further details please refer to the NHSC Installation Guide.
F.CLEANING DUST AND POLLEN DEPOSITS
(1)Dust, pollen, and animal nests must be periodically removed from the humidifier. This is best accomplished with a vacuum or with compressed air. When cleaning the humidifier focus on the following areas:
(a)Exhaust and heater fans
(b)Heater coil
(c)Case louvers
(d)Heat sinks (if applicable)
(e)Electronics
(f)Case floor
G.RESTARTING AFTER FREEZING
(1)In the unlikely event that the humidifier must be restarted after freezing, the following procedure should be followed:
(a)Inspect all hoses, fittings, valves, and seals for cracking or damage. Since water expands when it freezes, connections may have come loose, or fittings may have cracked. If any parts are damaged contact your NORTEC representative for replacement parts.
(b)Power the humidifier on. The heater and fan circuit will automatically power on and begin to warm the case.
