Page 10: Humidifier Piping
Humidifier Piping 2.4.1 Steam Generator Humidifier The standard humidifier on Data Aire systems is a steam generator type with a disposable cylinder. The humidifier makeup water should be brought to the humidifier through the field connection opening using 1/4" copper tubing. A compression fitting is provided at the humidifier. -
Page 11: Electrical Connections
Remote Shutdown Every Data Aire chilled water unit has remote shutdown contacts. These are intended for a field supplied dry contact or switch to be wired across two terminals. When the contact or switch opens, the control circuit power is interrupted and the unit shuts down, including the control panel. -
Page 12: Remote Sensors
Remote Sensors Remote sensors are optional. Although existing unit mounted sensors can be removed for remote mounting, the remote sensor option provides a more convenient means of field installation. This is because the sensors are already connected to a predetermined length of cable and come mounted in a remote sensor enclosure. -

DAP III control panel as well as peripheral equipment. Data Aire’s chilled water unit wiring diagrams will have a drawing number which starts out with the three letter designation, “DAC”. An example of a typical diagram, DAC-S-813, is shown on page 18. -
Page 14: Regular Maintenance Items
Only one or two pumps from a manual gun are required. 5.4 Humidifier Canisters Steam generator type humidifier is standard on Data Aire Series equipment. There is no maintenance required other than to replace the canister as required. This frequency will depend on usage and water type. -
Page 15: Heating Elements
For instance motors are inductive loads which require time delay fuses. Electric reheat and humidifiers are resistive loads requiring fast acting fuses. 5.6 Heating Elements Heating elements do not normally require maintenance. However sometimes they may accumulate a film of dust or dirt when unused for extended periods of time. When energized, the burning debris can create smoke or unpleasant odor. -
