Maintenance
General
To ensure proper performance and long operating life of the GS humidifier, it is recommended that the
appliance and installation be inspected at least once a year by a qualified service person. A proper
maintenance schedule should be followed. Since the amount and type of maintenance required is generally
as a result of how much the humidifier operates, all GS humidifiers monitor the amount of steam produced
over time and will indicate when service is required. All units come factory set with a service interval of 500
hours. This service interval can be adjusted through software (GSTC models) or by dip switch settings (GSP
models) on the logic control board.
All maintenance work must be performed by experienced and trained personnel.
Periodic cleaning of the screens in the vent terminal (where applicable) is recommended.
NOTE: Use only NORTEC original parts to replace damaged or defective components. Failure to do so may
cause improper operation of the humidifier and will void warranty.
Draining the Tank
During extended periods of inactivity such as off season or periods of very low demand, it is advisable to
drain the water from the tank. On all models this is accomplished by switching the unit to “Drain”.
Do not remove the front clean out port on the tank until the unit has completely drained. On GS 300-600
units do not remove the top clean out ports on the tank unless the water has cooled or the unit has
completely drained.
Ensure that power is switched on again during periods of demand.
The GSTC model of the Gas Steam humidifier includes a pre-cleaning sequence feature. When activated
(through the keypad), the unit will flush the humidifier, refill with cold water, and flush again reducing the
scale accumulated at the bottom of the tank.
