2. Steam Requirements - High Pressure
Inlet ---------- 1-inch supply line connection ----- qty. one (1) at top manifold.
Return ------- 1-inch return line connection -----qty. one (1) at top manifold.
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 (25.4 cm) riser. This will prevent any condensate from draining towards the
dryer.
b. The steam supply piping to the dryer must include a 12-inch (30.48 cm) rise 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.
d. Shutoff valves for each dryer should be installed in the supply line, return line, and drip trap return line.
This will allow the dryer to be isolated from the supply main and the return main if the dryer needs
maintenance work.
e. Install an inverted bucket steam trap and check valve at least 12-inches (30.48 cm) below the steam coil
as close to the coil as possible.
1) A trap with capacity of 400 pounds of condensate per hour (181.5 kg/hr) at 125 PSI (8.6 bars) is
needed for each unit.
f. The supply line and the return line should be insulated. This will save energy and provide for the safety
of the operator and maintenance personnel.
