I. Indoor Freeze Protection
(1) 150-7058 - GSTC Indoor Freeze protection package provides the unit configured
with keep warm feature, remote fault indication and a normally open drain valve to
protect if freezing conditions may occur. The keep warm feature will ensure the
water temperature is kept between 140ºF (60ºC) and 160ºF (71ºC).
(2) The remote fault indication will allow service personnel to be advised of the unit’s
operational status and the normally open drain valve will ensure the unit is drained
if a power outage.
(3) Drain and fill lines outside of the cabinet, must be protected from freezing with heat
trace. Unit must be enclosed in a weather enclosure with heat source.
(4) A remote alarm must be installed in case the unit faults using remote fault
indication and status indication.
J. Outdoor Freeze Protection (Standard with all GS Outdoor Enclosures)
(1) Outdoor units are configured with the Keep Warm feature enabled to maintain the
tank water temperature between 140ºF (60ºC) and 160ºF (71ºC). Included is a
factory installed normally open drain valve that will ensure the unit drains in the
event of a power outage. Also a factory-installed heater will be included to
maintain an operating temperature range within the electrical compartment. The
heater is powered from the humidifier. Field supplied heat-tracing needs to be
installed on all fill line piping exposed to outdoor temperature. If fill line pipe
freezing is a concern a field supplied normally open valve can be used to drain the
fill line.

worldwide using standard internet connections. This advanced software shows
graphic representations of the humidifier and its key parameters (up to 75
functions).
L. LINKS 2
(1) Nortec LINKS 2 is the combination of LINKS (building management system
communication hardware) and OnLine (Internet communication hardware) allowing
humidifiers to communicate to a building management system (BMS) as well as
the Internet. Up to 8 humidifiers can be connected to 1 LINKS 2 controller (1
master and 7 slaves). The controller is factory installed and is located internally to
the humidifier. Simply specify at the time of order the operating protocol needed.
LINKS 2 comes standard with Internet capabilities however OnLine service needs
to be specified at time of order.
