VAPORSTREAM INSTALLATION, OPERATION, AND MAINTENANCE MANUAL

INSTALLATION

Electrical noise can produce undesirable effects on electronic control circuits,
thereby affecting controllability. Electrical noise is generated by electrical
equipment such as inductive loads, electric motors, solenoid coils, welding
machinery, or ﬂ uorescent light circuits. The electrical noise or interference
generated from these sources (and the effect on controllers) is difﬁ cult to deﬁ ne,
but the most common symptoms are erratic control or intermittent operational
problems.

Most electrical noise problems can be prevented by using proper wiring
practices and techniques to prevent coupling or inducing of electrical
interference into control circuits. The following wiring practices should minimize
interaction of noise and controls:

• Connect humidiﬁ er and control cabinet to a code approved earth ground.

• Separate the line voltage wiring from low voltage control circuit wiring

when routing electrical wiring inside the control cabinet.

• Use separate electrical conduits for line and low voltage wiring to the

humidiﬁ er.

• Do not use chassis or safety grounds as current-carrying commons. A safety

ground should never be used as a conductor or neutral to return circuit
current.

• When wiring external electrical connections to humidistats, humidity and

temperature transmitters, or control signal input connections from a building
control system, use 18-gauge minimum (1 mm2) plenum-rated twisted pair
wire with cable shielding (screening) and drain wire for grounding.

• Return all shielded (screened) cable connections to the control cabinet for

grounding.

Do not ground shield at the device end.

Wiring:

Black, top probe rod (full water condition)

White, middle probe rod (reﬁ ll water condition)

Red, bottom probe rod: Low water condition, tap/softened water

Low water cutoff switch, RO/DI water

OM-VL3-11

Low water cutoff switch (RO/DI water only)

Important:

Do not use shielded (screened) cable for water
level control devices.

WARNING

Excessive moisture hazard

DriSteem strongly recommends
installing a duct airﬂ ow proving switch
and a duct high limit humidistat. These
devices prevent a humidiﬁ er from
making steam when there is low airﬂ ow
in the duct or when the RH level in the
duct is too high. Failure to install these
devices can result in excessive moisture
in the duct, which can cause bacteria
and mold growth or dripping through
the duct.
