Chapter 2 Important Instructions 2.1 Before Attempting Repairs Moving parts can cause serious injury or death. Before attempting repairs, follow proper shutdown procedures, remove power, and allow the machine to fully cool before commencement of service. Safety is of primary concern with any maintenance or repair operation.
Figure 2.1: Serial Decal Read, follow, and obey these safety rules! The B&C Technologies Technical Service Department is available to answer any questions you may have about the operation and servicing of your machine. Please call with any questions or concerns about the operation of your machine. 2.2 Parts Ordering Information If you require literature or spare parts, please contact your local distributor.
Figure 2.2: Key Symbols 2.3 Key Symbols Anyone operating or servicing this machine must follow the safety rules in this manual. Particular attention must be paid to the DANGER, WARNING, and CAUTION blocks which appear throughout the manual and shown in figures 2.2 on page 5 and 2.3 on page 6.
Figure 2.3: Key Symbols 2.4 Safety Information Installation Notice: For personal safety and for proper operation, the machine must be grounded in accordance with state and local codes and in the USA in accordance with the National Electric Code, article 250-96. Elsewhere, the equipment should be grounded in accordance with ANSI/NFPA 70, or the Canadian Electrical Code, CSA C22.1. The ground connection must be to a proven earth ground, not to conduit or water pipes.
6. Never attempt to service the machine while it is running. Never reach over, under, around, or behind any safety device, or into any area near moving parts or hot surfaces without shutting off power and allowing the machine to adequately cool. 7. Read, understand, and follow all safety instructions. Do not come close to moving parts and hot surfaces. Do not wear loose clothing, jewelry, neckties, or any other garment that could be come caught in the machine while operating or near the machine. 8.
Chapter 3 Installation 3.1 Receiving Inspection Upon receipt of the equipment, visually inspect for shipping damage and note any damage with the carrier before signing the shipping receipt, or advise the carrier of the damage as soon as it is noted. If damage is discovered, a written claim must be filed with the carrier as soon as possible. Note: Warranty is VOID unless the equipment is installed according to instructions. The installation must comply with the minimum requirements listed in this manual.

Figure 3.6: Gas/Steam Heat Electrical Requirements Figure 3.7: Electric Heat Electrical Requirements 3.2 Electrical Installation Electrical connections should be made by a qualified electrician in accordance with all applicable codes or requirements. Use a separate branch circuit to power each machine. Do not share circuits with lighting or any other equipment.
Figure 3.8: Gas Plumbing Detail 3.3 Gas Connection 3.3.1 Gas Supply Line • 1” IPS pipe is recommended. • 1” approved tubing is acceptable for lengths under 25 ft (6.1 m) if local codes and gas supplier permit. • Must include 1/8” NPT minimum plugged tapping accessible for test gauge connection, immediately upstream of the gas connection to the dryer (see figure 3.8 on page 15). • Must include a shutoff valve: An individual manual shutoff valve must be installed within 6 feet (1.
an elbow and a 1” flare x 1” NPT adapter fitting between the stainless steel gas connector and the gas inlet of the machine as needed to prevent kinking. Option 2: Other approved piping: Lengths under 25 feet (6.1m) use 1” approved tubing. Lengths over 25 feet (6.1m) should use larger piping. Pipe joint compounds that resist the action of gas must be used. DO NOT USE TEFLON TAPE. R /PTFE IMPORTANT: Be certain the dryer is configured for the type of gas being used.
Important: Insulate all steam and return lines for the safety of the operator and service technician. Important: All steam components must be rated for a minimum of 200 psi (14 bar) working pressure. Shut off valves must be installed upstream of the steam inlet, and downstream of the steam trap so that the equipment can be isolated for maintenance or emergency. Important: Support all steam lines and components to minimize the load on the steam connections to the dryer.
Table 3.2: DE Series Compressed Air Requirements Compressed Air Pressure Minimum 70 psi Nominal 80 psi Maximum 90 psi Air connection to system — 1/8-inch N.P.T. No air regulation or filtration is provided with the dryer. External regulator and filtration must be provided. It is suggested that a filter be added to the compressed air line just before the dryer connection (B&C P/N 270-318 or locally obtained). This is necessary to insure that clean and dry air is delivered to the equipment.

Figure 3.11: DE Series - Proper Exhaust is critical for safety! be blocked. Blocking the air inlets prevents proper combustion, and will yield poor results, and possibly harmful combustion byproducts. See recommended exhaust style in Figure 3.12 on page 21. Important: Do not interrupt the flow of make-up air or the exhaust! Use the shortest possible path with the fewest number of bends to connect to the outlet ductwork. Measured backpressure should not exceed 0.
Figure 3.12: DE Series - Exhaust Detail Figure 3.13: Fire Suppression Water Connection WARNING: Do not store flammable materials near the dryer. WARNING: Do not allow lint to accumulate in or around the dryer. Lint is highly flammable. WARNING: Do not allow the exhaust or fresh air supply to be restricted or interrupted in any way. 3.8 Enclosure Requirements It is recommended that the rear of the dryer be positioned no less than 2 feet (24 inches) from nearest obstruction (i.e.
Figure 3.
Figure 3.15: DE Series Make Up Air Detail located a minimum of 12 inches above the top of the dryer. Important: Even though a minimum of 12 inches is required, 18 inches or more is suggested, for steam dryers and especially in cases where sprinkler heads are over the dryers. Note: When fire sprinkler systems are located above the dryers, a minimum of 18 inches above the dryer console (module) is suggested.
is distributed equally to the dryers. Allowances must be made for remote or constricting passageways or where dryers are located at excessive altitudes or predominantly low-pressure areas. Note: Avoid locating the exhaust next to the fresh air supply intake.
Chapter 4 Operation The following items should be checked before attempting to operate the dryer: 1. Read and follow caution, warning and direction labels attached to the dryer. 2. Check incoming supply voltage to be sure that it is the same as indicated on the dryer serial decal. 3. GAS MODELS – check to assure that the dryer is connected to the type of gas indicated on the dryer serial decal. 4. GAS MODELS – the sail switch damper assembly was installed and adjusted at the factory prior to shipping.
ALL dryers are thoroughly tested and inspected before leaving the factory. However, a preoperational test should be performed before the dryer is placed into service. It is possible that adjustments have changed in transit or due to marginal location (installation) conditions. 1. Turn on electric power to the dryer. 2. Make sure the main door is closed and the lint drawer is securely in place. 3.
i. The steam damper should not ”slam” (open or closed) when it reaches the end of (piston) travel. Additionally, the steam damper should not bind and/ or stop during travel. If either of these conditions occur, the flow control must be adjusted. Make a complete operational check of ALL safety-related circuits (i.e., lint drawer switch, and sail switch on gas models). IMPORTANT: The drying cylinder is treated with a protective coating.
(b) Select Heat Level: i. ii. iii. iv. No Heat Perm Press (150 F, 65 C) Low Heat (180 F, 80 C) High Heat (200 F, 93 C) (c) Turn Dry Time knob to desired time (at least 5 minutes or more). (d) Turn Cool Down knob to desired time (must be set, or dryer will not start). (e) Press Start button.
Chapter 5 Troubleshooting 5.1 No Heat Familiarize yourself with the call for heat path as highlighted on the portion of the schematic, figure 5.3 on page 32, and the simplified flow chart shown in figure 5.1 on page 30. Figure 5.2 on page 31 has a troubleshooting flow chart which will enable you to quickly diagnose the problem and take corrective action.
