3. Installation Instructions
To insure an adequate supply of steam is provided, be sure that the steam lines and steam return lines are
sized and laid out as stipulated in this manual. Inadequate steam lines and steam return lines or improper
steam plumbing will result in poor performance and can cause component failure. Clean, dry steam must be
provided to the dryer.
IMPORTANT: Steam coil failure due to water hammer by wet steam will VOID THE WARRANTY.
a. The pressure of the condensate in the steam supply will cause water hammer and subsequent heat
exchanger (steam coil) failure. The steam supply connection into the main supply line must be made with
a minimum 10-inch riser. This will prevent any condensate from draining towards the dryer.
b. The steam supply piping to the dryer must include a 12-inch rise along with a drip trap and check valve.
This will prevent any condensate from entering the steam coil.
H. STEAM INFORMATION
It is your responsibility to have ALL plumbing connections made by a qualified professional to assure that the
steam plumbing 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-75 is manufactured with a pneumatic (piston) damper system which requires an
external supply of air (80 PSI +/- 10 PSI).
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.
IMPORTANT: Coil failure due to improper PH level will VOID THE WARRANTY.
2. Steam Requirements - High Pressure
Inlet -------- 1" supply line connection -- qty. one (1) at top manifold
Return ----- 1" return line connection --- qty. one (1) at top manifold
