Maintenance
6.1
General
To ensure proper performance and long operating life of the Nortec GS humidifier, Condair recommends
inspection of the appliance and installation at least once a year by a qualified service person. The amount
and type of maintenance required is generally dependent on how much the humidifier operates. The
Nortec GS humidifier monitors the amount of steam produced over time and will indicate when service
is required. All units come with a default service interval of 1000 hours, which can be adjusted in the
control software.
The combustion air blower motors are permanently lubricated and do not require lubrication.
The gas valves in the Nortec GS humidifier are negative static pressure regulating valves. The valves are
factory-set for the correct gas type. The valve setting listed on the product rating plate is shown relative
to atmosphere – this setting will always remain constant. Contact the factory if adjustment is needed.
IMPORTANT!
Tampering with the gas valve, without the express consent of Condair, will void the
warranty.
In general, the burners do not require adjustment or servicing. The combustion chamber and heat-
exchanger tubes are all fabricated from stainless steel, and do not require internal cleaning.
The exhaust vent connected to the Nortec GS humidifier does not require cleaning, but needs to be
inspected regularly for leaks, blockages, sagging and proper condensate removal.
For proper and safe operation of the unit, the area around the air intake in the unit must be kept clear of
all obstructions. If an air intake vent is used, it must be inspected for leaks and obstructions (including
the intake terminal).

for other maintenance requirements. Also perform
regular inspections when the unit is operating – refer to
"Inspections During Operation" on page 46

IMPORTANT!
Damage caused by use of non-approved parts is not covered by warranty. Use only
original Condair replacement parts.
