Drain Water Cooling; Foam Protection; Internal Fusing; Remote Fault Indication - Nortec NHTC Installation And Operation Manual

Drain Water Cooling

For installations where drain water must be cooler than 140ºF (60ºC) a kit is available which
consists of a double fill valve. The second fill valve adds additional water to the fill cup while
the humidifier is draining to cool the water more than the single fill valve.
Drain Water Cooling (External)
Pneumatic and electric drain water coolers are available from Nortec for installation outside the
humidifier or on condensate drains from steam traps, distributors, and SAMe headers. If
condensate cannot be routed back to the humidifier tank via the humidifier's fill cup then an
external drain water cooler may be required to meet regulations restricting the temperature of
hot water that can be fed to drain. The external drain water cooler is only available for field
installation.

Foam Protection

NORTEC's NHTC/PC includes software detection of foaming which in most cases should be
sufficient to address waters which can cause foaming. For more severe cases an optional foam
prevention kit is available. The kit consists of an external float chamber, steam outlet , hose
and fittings required for installation. The kit can be factory or field installed.

Internal Fusing

An optional internal fusing kit is available for all models of NHTC/PC. The kit provides extra
internal protection to the humidifier and must always be used in conjunction with an external
fused disconnect. The Internal fusing option is only available as a factory installed option.

Remote Fault Indication

An optional remote fault kit is available that can provide remote indication of humidifier status.
The kit can be factory or field installed. See also Remote Fault Option Wiring on page 27 for
more information about the remote fault indication kit.
Outdoor Model
The outdoor model of the NHTC performs in the same way as the indoor model except as noted
in the manual addendum that is supplied with it. Refer to additional installation instructions for
the outdoor model in the addendum.
