H.  STEAM INFORMATION

It is your responsibility to have ALL steam plumbing connections made by a qualified professional to ensure that
the installation is adequate and conforms to 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 dryer is manufactured with a pneumatic (piston) damper system, which requires an

external supply of clean, dry, regulated air (80 psi +/- 10 psi [5.51 bar +/- 0.69 bar]).  Refer
to Steam Damper Air System Connections.

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 ------ 1-1/4” supply line connection ---- quantity one (1) at top manifold.
Return --- 1-1/4” return line connection ---- quantity one (1) at bottom manifold.

Shaded areas are stated in metric equivalents

*  Minimum operating pressure for optimum results is 100 psig (689 kPa).

3. Installation Instructions

To ensure that an adequate supply of steam is provided, be sure that the steam supply lines and steam
return lines are sized and laid out as stipulated in this manual.  Inadequate steam supply lines and steam
return lines, or improper steam plumbing, will result in poor performance and can cause component failure.
Clean, dry, regulated 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
within a minimum 12-inch (30.48 cm) riser.  This will prevent any condensate from draining towards the
dryer.

b. The steam supply line to the dryer must include a 12-inch (30.48 cm) riser along with a drip trap and

check valve.  This will prevent any condensate from entering the steam coil.

c. Flexible hoses or couplings must be used.  The dryer vibrates slightly when it runs and this will cause the

steam coil connections to crack if they are hard-piped to the supply and return mains.
