Installation Instructions
To ensure 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.
The pressure of the condensate in the steam supply line 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
The steam supply line to the dryer must include a
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.
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.
Install an inverted bucket steam trap and check valve at least
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.
Water pockets in the supply line, caused by low points, will provide wet steam to the coil possibly causing steam coil damage. ALL horizontal runs of steam supply piping should be pitched

!Flexible hoses/couplings must be used. Coil failure due to hard plumbing connections will
VOID THE WARRANTY.
