￿Conductivity: Measured in micromhos. Follow the directions for the conductivity pen found inside the box. Multiply the digital reading by 1.5. The recommended operating range for conductivity is 0 - 1500 micromhos. Consult the factory is you measure outside these parameters.

￿NORTEC recommends performing a semi-annual water analysis to ensure optimal performance.

￿The humidifier is intended to operate on cold potable tap water.

￿DO NOT use a hot water source to supply the humidifier. Minerals will adhere more easily to surfaces and the fill valve's small flow regulating orifice could become plugged.

￿Consider using a water softener. Longer operating times between tank cleaning will be reached on softened water.

￿Reverse osmosis (RO) water can provide very long times before cleaning is required since it is cleaner than softened water. Deionized (DI) water may be used with all models. Consult your NORTEC representative for quote on a water treatment system.

SAFETY INSTRUCTIONS

Refer to front cover and page 1 of this guide.

FAULT CONDITIONS

This appliance is equipped with a self diagnostic ignition module which identifies a fault code when it occurs. Refer to the fault & warning list on pg 60.

GSTC MODELS

Faults are indicated with a fault message on the display of GSTC models. Recovery from lockout requires resetting of the humidifier. This can be achieved by momentarily shutting off the power switch then turning it back on, or by pressing the reset button on the logic control board mounted inside the electrical cabinet.

A history of all faults is stored in memory of the software and can be viewed through the service level on the display. Refer to the keypad display menu structure at the end of the manual.

GSP MODELS

Faults are indicated on GSP models with a fault code on the small display screen attached to the logic control board. The display can be viewed by removing the front electrical door. Check the display for the fault code before shutting off power to the unit. Resetting the humidifier clears the fault. This can be achieved by shutting off the power switch, then turning it back on, or by pressing the reset button on the logic control board. A list of all fault codes and the type of fault they represent is located near the back of the manual.

MAINTENANCE

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.
