GTS-DI water supply piping

GTS-DI models control water level with a float valve, and have

a 3/8" pipe thread (DN10) connection. For DI models with the

end-of-season drain option, a solenoid valve is installed prior to

the float valve. The end-of-season feature shuts off the fill water

supply and drains the tank when there is no demand for humidity

for 72 hours. (This length of time is a default setting and is

user-adjustable. See the Vapor-logic4 Installation and Operation

Manual for more information.)

When using nonmetallic tubing for supply water, it must be

rated for 212 °F (100 °C) minimum continuous operating

temperature. DRI-STEEM recommends installing a 3' (1 m) piece

of noninsulated stainless steel pipe directly off the humidifier prior

to connecting to the nonmetallic tubing. When using nonmetallic

tubing, DRI-STEEM recommends the installer place a 2" (50 mm)

water seal/loop in the supply line to isolate steam during DI/RO

water system maintenance. (See Figure 21-1 on page 21.)

DRI-STEEM recommends installing a strainer in the water supply

line to prevent clogging of the solenoid valve or float valve orifice.

A strainer is highly recommended when the humidifier has the

end-of-season drain option. The strainer prevents particulate from

collecting at the solenoid valve seat.

In order to minimize DI/RO water use, disconnect factory piping

to the water tempering device and pipe directly to tap water.

W A R N I N G !

If the GTS-DI humidiﬁer is supplied with tap water, the ﬂoat valve

assembly will become clogged and particulate will accumulate on the

low water cutoff switch (ﬂoat switch). This will cause failure of a critical

safety circuit and the potential for a dry tank ﬁre. A dry tank ﬁre can

cause heat exchanger, vapor hose, and wire insulation failure, severe

property damage, severe personal injury, or death.
