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.
