INSTALLATION & MAINTENANCE INSTRUCTIONS
MODEL SW-2 IN ROOM MOUNTED HUMIDIFIER
Periodically the atomizing unit should be taken from
the reservoir and given a careful visual check. The
pump tube should be spun by hand to make sure that it
is free to revolve without binding. See maintenance
instructions.
Your humidifier has been designed and engineered to
give, with proper care, many years of trouble free
service. Therefore, if this unit ceases to operate
properly, we suggest you contact your local dealer. If
we, at Humidity Source, can be of any assistance to
you, please feel free to write, call or e-mail. Typical Installation

This space type humidifier is designed so that it may
be shelf mounted. The shelf should be at least 18”
(45.7cm) below the ceiling and 6 feet (1.8m) above
floor. The directional vapor dome should be positioned
to diffuse moisture without striking any obstructions
closer than six feet and maintain 24” minimum between
each side of the humidifier and any wall or obstruction.
PROCEDURE
Run a water supply line using 1/4” o.d. copper or
plastic tubing or 1/8” pipe. Keep the line to the rear of
the unit to avoid creating an obstruction.
Flush water feed lines before making final connection
to avoid having cutting oil, pipe scale, or chips which
may clog the float valve.
Turn on water valve, adjust water level to 1” below the
overflow connection.
WIRING
Adjustment is easily made using the adjusting thumb
screw for higher or lower water level as illustrated.
The atomizer motor draws .67 Amps at 115 Volts A.C.
single phase and 60 Hz service.
SERVICE & REPAIR
Provide standard electric receptacle to receive electric
cord from humidifier. Have the hot leg of service to this
receptacle wired in series with the humidistat terminals
and use a standard disconnect switch if required. See
wiring diagram.
Should this humidifier need service or repair some time
in the future, return only atomizing unit direct to the
factory.
CARE OF THE MACHINE
This humidifier may be run continuously or operated by
means of a humidistat.
Due to air washing while the humidifier is in operation,
a deposit of dirt and dust may settle in the bottom of
the water reservoir and screen, and it is recommended
that both be cleaned regularly.
Our standard human hair element humidistat model P-
825 is correct for most applications maintaining up to
60% RH.

For humidors and other high humidity applications, or
for more precise control, use the electronic humidistat
model W351A. This model also has an optional digital
display module to indicate the set point and the actual
R.H. in the room.
