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.
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 (6.096 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

The dryer is manufactured with a pneumatic
(piston) damper system, which requires an

external air supply of 6 cfh @ 80 psi +/- 10 psi (0.17 cmh @
5.51 bar +/- 0.69 bar).

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.
