1. A chamber without a vent will cause back pressure which could damage the humidifier Also if another pressurized source is being introduced in the chamber the vent will allow both the humidifier and other source to operate properly Without a dedicated vent the other pressurized source will use the humidifier as a vent This will cause the mist to back up into the electronics compartment Never place the humidifier inside the chamber The fans and electronics will become exposed to the wet air and will guickly fail Always operate the humidifier outside the chamber and attach it with the supplied 1 tubing Never immerse the humidifier for filling or cleaning Clean the ultrasonic transducer freguently and thoroughly Any dirt or particle build up on the transducer will cause stress to the electronics Once the electronics overheats and stops working the entire humidifier must be replaced Freguent cleaning will allow the electronics to work normally for many years Use distilled or deionized water only 5 0 MODEL 5472 The Model 5472 Ultrasonic Humidifier shown in Figures 5 0 1 and 2 is a premium version of the Model 5462 Ultrasonic Humidifiers The Model 5472 has many features not found in the Model 5462 5 Gallon Water Tank for cC gt Deionizer long term applications Filtering Column p 7 1 Hose Barb for A Mist Output T Water Basin with Thumbscrew Screw Down Lid with Silic2. continuously to circulate the moist air throughout the chamber All ETS Chambers have fan s already installed Model 5462 Model 5472 SET UP General NOTE In addition to the following procedure the customer must provide a_vent on the chamber or the humidifier will not work The humidifier operates b displacing the dry air within the chamber If the dry air cannot escape the moist air will not be blown in Many enclosures are not airtight and may not need additional venting For those that do a small 12 hole in the corner opposite the humidifier input barb should suffice 1 Install the 1 NPT x 1 Hose barb on the chamber A Determine the minimum height at which the barb can be installed l Place the humidifier next to the chamber Il Measure up 6 from the top of the output barb on the humidifier Il Mark the chamber at that height That is the minimum height at which the barb can be installed Mounting the barb lower may cause the humidifier to function improperly IV For a chamber and humidifier placed on the same level surface the installation height should be approximately 18 B Drill a 825 hole at the previously determined location and install the barb The threaded portion will go inside the chamber and be held in place with the 1 2 NPT nut The barb will be outside the chamber If the humidifier is being used with an ETS Chamber the barb is already installed 2 Place the humidifier a

13. roperly 5 2 1 Features This humidifier operates in the same manner as the Model 5462 The principal difference between the two systems is as follows The Model 5472 uses a small linear air pump to force the mist into a chamber instead of the small blower fan used in the Model 5462 The pump can withstand substantially more backpressure than the blower fan This enables the humidifier to operate efficiently with very little chamber venting The water and mist cannot come in contact with any electronic components which can happen in the Model 5462 The electronics are completely isolated from any contact with the water in the Model 5472 The Model 5472 can be modified to use compressed air or an inert gas as the propulsion source instead of the air pump The 5472 can also be modified for to be a close loop system Contact ETS for details The Model 5472 uses an electronic float switch to control the water level minimizing the chances of any water overflow from the unit A second electronic float switch acts as a water sensor to protect the Ultrasonic Transducer NOTE If the 5472 Ultrasonic Transducer turns on without water it will cause damage to the Transducer Element For replacement Transducer Elements contact ETS for details 5 The Model 5472 includes a water deionizing column as a standard feature 5 22 Operating Precautions 1 The Model 5472 should operate reliably if the following precautions are
