H. STEAM INFORMATION
It is your responsibility to have ALL steam plumbing connections made by a qualified professional to assure that
the installation is adequate and conforms with local and state regulations or codes.
IMPORTANT: Failure to comply with the requirements stipulated in this manual can result in
component failure which will VOID THE WARRANTY.
NOTE: The ADS-120ES is manufactured with a pneumatic (piston) damper system which
requires an external supply of clean, dry, regulated air (80 psi +/- 10 psi). Refer to
Steam Damper Air System Connections, Section H, item 3.
1. STEAM COIL PH LEVEL
The normal PH level for copper type steam coils must be maintained between a value of 8.5 to 9.5. For steel
type steam coils the PH level must be maintained between a value of 9.5 to 10.5. These limits are set to limit
the acid attack of the steam coils.

plumbing will result in poor performance and can cause component failure. Clean, dry, regulated steam
must be provided to the dryer.
