Fractal Humidity System
GENERAL INFORMATION
The Service Case Humidification system is an automatic
moisture maintenance system designed to raise humidity
levels in any new or existing service case counter or
refrigerated floral display. It delivers a damp fog into the
service case or floral display at selected intervals by using
a combination of air and water.
The system consists of a humidification nozzle assembly,
water filtration/regulator unit, remote timer, and air
compressor unit (see attached diagram).
PLEASE READ ALL INSTRUCTIONS BEFORE
BEGINNING INSTALLATION
1. Installation of Regulator Assembly and water hookup
Procedure -
a. Tie into the water supply line under or near the
service case or floral display by using either a
compression or sweat “Tee” fitting with a 1/2"
FPT. (In cases of new store construction, the
appropriate 1/2" FPT fitting may already be
stubbed up under the case).
b. Screw the provided 1/4" x 1/2" MPT gray plastic
push-in filing into the 1/2" FPT water fitting.
c. To connect tubing for water, push one end of the
1/4" black poly tubing into the plastic push-in
fitting at the Tee”. Measure and cut tubing to
length and insert the opposite end of tubing into
the 1/4" push-in fitting on the Regulator
Assembly marked “CITY WATER”.
d. Connect another length of black poly tubing to
the push-in fitting (or plastic push-in “Tee” for
SCH-2) labeled ‘WATER” on the Regulator
Assembly. Measure and cut this piece of tubing to
length and connect the opposite end to the
push-in elbow fitting on the back of the nozzle
assembly. It may be necessary to drill access
holes through the bottom of the case for the
tubing lines - if so, ensure these holes are sealed
with silicon or similar substance.
TECHNICAL PROCEDURES ARE NOW COMPLETE
2. Start-up, Testing and Adjustment Procedures
a. Turn water on. Pressure gauge on Regulator
Assemblies should read approximately 1-4 psi.
b. Set Timer at each station for a 60 second “On
Time” and I minute “Off Time” cycle. (SEE
ATTACHED CONTROLLER SETTING
INSTRUCTIONS!) This setting, is for testing, on]
and will allow enough time for the water to 1111
the line and reach the nozzle.
c. Plug in the Controller to the 115V outlet.
Compressor and solenoid valves will activate and
plumes from nozzles will independently appear
shortly thereafter.
d. If humidity plume is too light or too heavy. Adjust
the Regulator accordingly. Adjust water pressure
by lifting up the yellow locking cap on the top of
the Regulator and turn clockwise (to increase
pressure) or counter- clockwise (to decrease
pressure). Make Regulator adjustments ONLY
when system is running. Push down on cap to
relock the regulator on the desired pressure.
e. A desired setting would be a pressure that
provides a solid constant plume from the
nozzle(s), but shuts off cleanly when the cycle
ends. If the nozzle(s) continue to emit a stream
of water or drip at shut-off, the pressure should
be decreased.
f. On completion of testing/adjustment, reset
Controller to recommended “On/Off’ settings
as per Owner’s Guide which is included in the
packing carton.
g. Carry out training on tip cleaning and Timer
settings with department manager and/or staff.
