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.
Care
must be
exercised when leveling steam dryers into final position. After leveling the dryer, check the
downward pitch of the heat exchanger from front to rear with a level. Likewise, check the downward pitch of
the return condensate manifold toward its outlet part. Absence of these downward pitches will result in probable
water hammer and premature heat exchanger fracture and leakage.
The presence of condensate in the steam will cause water hammer and subsequent heat exchanger failure. The
steam supply connection
must be
taken from the top of a well-dripped steam main. If the supply run-out to the
dryer exceeds 20 feet (6.1 meters), it
should be
dripped just before the control valve with a proper trap and dirt
pocket.
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 (80 PSI ± 10 PSI [5.51 bars ± 0.68 bars]).
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
* Minimum operating pressure for optimum results.
3. Installation Instructions
To insure 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 steam
must be
provided to the dryer.
IMPORTANT:
Steam coil failure due to water hammer by wet steam will VOID THE WARRANTY.
