Plumbing; Water Supply Line; Drain Line; Steam Line - Nortec GH Series Instaliation, User & Maintenance Manual

PLUMBING
NOTE: All water supply and drain line
connections should be installed in
accordance with local plumbing codes.
WATER SUPPLY LINE
1. The humidifier is intended to operate on cold
potable tap water.
2. If the potable tap water is very hard, longer
operating times between tank cleaning will be
reached on softened water.
3. Reverse osmosis (RO) water can provide very
long times before cleaning is required since it
is cleaner than softened water. However, it is
also more corrosive. Consult factory.
Deionized (01) water may be used with
specific models. Consult NORTEC
representative.
4. DO NOT use a hot water supply to humidifier.
Minerals will adhere more easily to surfaces
and the fill valve1s small flow regulating orifice
could become plugged.
5. Standard fill valves are sized for water
pressure ranging from 30 to 80 psig (ideally 55
to 60 psig). For other pressures, consult
factory. This pressure should be measured at
the humidifier if the water pressure is suspect.
6. ALWAYS supply and install a shut off valve in
the water supply line dedicated to the
humidifier to facilitate servicing. Use
1/211 00
copper to within 4 feet of the humidifier.
Reduce copper to 3/8
11 00 and connect to the

- 10 -
factory-supplied 3/8 11 olive compression fitting
on the side of the humidifier.
DRAIN LINE
1. Humidifier is equipped with a 111 NPT drain
outlet connection on the side of the humidifier.
See Figure #15. A field-supplied funnel is
recommended. See Figure #16. It will
prevent backup due to partially blocked or
badly installed drain lines.

NOTE: Steam Hose Should Not Reach Bottom OlThe Funnel.
2. The drain line should not end in a sink used
frequently by personnel, or where plumbing
codes prohibit it. Route to a floor drain or
equivalent for safety reasons, since drain
water from humidifier can be very hot.
3. Keep drain lines as short as possible. Keep
drain lines sloped down, not level and not up
since low spots in drain lines will accumulate
sediment and cause backup. The drain line
should be 111 0.0. copperpipe or larger. Do
not use plastic pipe for drain lines. Consult
factory.
STEAM LINE
1. Field-supplied hard copper with 1/211 thick
(min.) insulation is recommended for steam
supply, with NORTEC supplied steam hose
coupling used to make connection to
humidifier. See Figure #17.
