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.
A shutoff valve should be provided outside the air conditioner to allow disconnection for service.
An in-line water pressure regulator and strainer should be installed. Water pressure should be set
between 20 and 50 PSI.
The humidifier has a drain at the bottom which is factory piped to the main condensate drain line.
The dispersion tube also has a drain line. No additional field piping is required.
2.4.2 Dry Steam Humidifier
The optional dry steam type humidifier requires a strainer on the inlet steam line. An outlet
connection with a field-provided steam trap is also required. Steam pressure is typically 10-15 psi.

Leak Testing
No installation is complete until the entire system has been thoroughly checked for leaks. This
includes water lines, flare fittings, pressure controls, and Shrader fittings.
Check all humidifier water makeup lines, condensate lines, condensate pumps, chilled water
lines.
Tightening of fittings and valves is the responsibility of the installing contractor.
