26 3. Piping Connections ALL components/materials must conform to National Fuel Gas Code Specifications ANSI Z223.1-LATEST EDITION, or in Canada, CAN/CGA-B149.
27 Consistent gas pressure is essential at ALL gas connections. It is recommended that a 3/4-inch (19.05 mm) pipe gas loop be installed in the supply line servicing a bank of dryers. An in-line pressure regulator must be installed in the gas supply line (header) if the (natural) gas pressure exceeds 12.
28 H. STEAM INFORMA TION 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.
29 a. 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 10-inch (25.4 cm) riser. This will prevent any condensate from draining towards the dryer.
30 4. Steam Damper Air System Connections This dryer is manufactured with a pneumatic (piston) damper system, which requires an external supply of compressed air. The air connection is made to the steam damper solenoid valve, which is located at the rear inner top area of the dryer just in front of the electric service relay box.
31 5. Steam Damper System Operation The steam damper, as shown in the illustration below , allows the coil to stay constantly charged eliminating repeated expansion and contraction. When the damper is opened, the air immediately passes through the already hot coil, providing instant heat to start the drying process.
32 6. Steam Damper Air Piston (Flow Control) Operation Adjustment Damper operation was tested and adjusted prior to shipping at 80 PSI (5.51 bars). If damper air adjustment is necessary, locate the flow control valve and make the necessary adjustments as noted below.
33 I. PREP ARA TION FOR OPERA TION/ST AR T -UP The following items should be checked before attempting to operate the dryer: 1. Read ALL “ CAUTION ,” “ WARNING ,” and “ DIRECTION ” labels attached to the dryer.
34 J. PREOPERA TIONAL TESTS ALL dryers are thoroughly tested and inspected before leaving the factory. However, a preoperational test should be performed before the dryer is publicly used. It is possible that adjustments have changed in transit or due to marginal location (installation) conditions.
35 5. Make a complete operational check of ALL operating controls. NOTE: If computer program changes are required, refer to the computer programming section of the manual supplied with the dryer.
36 NOTES: 1. If the Anti-Wrinkle program is active, the light emitting diode (L.E.D.) display will continue to read “donE,” and the microprocessor controller (computer) will proceed through the Anti-Wrinkle program until the maximum “Active Guard Time” has expired or until the door i s opened, whichever comes first.
37 IMPORTANT: If the door is opened during a cycle, both the heat and motor will stop. However, the microprocessor controller (computer) will continue to count the time, either upward or downward, depending on which parameter is programmed.
38 NOTE: Pressing keyboard (touch pad) key “A”, “B”, “C”, “D”, and “F” will also start the dryer. The six (6) preprogrammed drying cycles “A” through “F” have been stored in the microprocessor controller (computer) memory. Refer to the Programming Manual supplied with the dryer for more specific operating instructions.
