H. STEAM INFORMATION

It is your responsibility to have ALL plumbing connections made by a qualified professional to ensure 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: This dryer is manufactured with a pneumatic (piston) damper system, which requires an external supply of air of 0.75 cfh @ 80 psi +/- 10 psi (5.51 bar +/- 0.69 bar).

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 bottom manifold.
