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 RegulatorAssembly 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 “CITYWATER”.

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 andAdjustment 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.

3.Warranty Conditions -

The SCH system carries a 1 year limited Parts Only warranty. Fractal Inc. will replace component parts that are found to be defective through normal operation or workmanship during manufacture.

b.Performance problems that are directly related to poor water quality are not the responsibility of the manufacturer.

THE MANUFACTURER WILL NOT BE RESPONSIBLE FOR EQUIPMENT PERFORMANCE PROBLEMS (DURING OR AFTER INSTALLATION). IF INSTALLATION, ADJUSTMENT, AND TRAINING IS NOT CARRIED OUT IN ACCORDANCE WITHTHESE INSTRUCTIONS. INSTALLING CONTRACTORS SHOULD BE AWARE THAT 24 HOUR SERVICE ASSISTANCE IS AVAILABLE BY CALLING THE ABOVE TELEPHONE NUMBERS.
