When the damper is closed, ambient air is drawn directly into the basket (tumbler), allowing a rapid cool down. Diagram 1 (below) shows the damper in the heating (open) mode, allowing heat into the basket (tumbler). Cool Down Mode 33 Diagram 2 (on page 33) shows the damper in the cool down (closed) mode, pulling ambient air directly into the basket (tumbler) without passing the coils. NOTE: With the dryer off or with no air supply, the damper is in the cool down mode as shown in Diagram 2 (on page 33). c. Steam Damper Air Piston (Flow Control) Operation Adjustment Damper operation was tested and adjusted prior to shipping at 80 PSI. If damper air adjustment is necessary, locate the flow control valve and make necessary adjustments as noted in the illustration below. {REAR OF DRYER) NOTE: TURNING KNOB ON FLOW CONTROL CLOCKWISE WILL RESTRICT AIR FLOW. TURNING COUNTER-CLOCKWISE WILL ALLOW HIGHER AIR FLOW. 34 I. Preparation for Operation The following items should be checked before attempting to operate the dryer: 1. Read and follow 4LL "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 data label located on the back of the dryer control (service) door. 1 3. Check to assure that the dryer is connected to the type of heat/gas indicated on the dryer data label (for GAS MODELS ONLY). 4. The sail switch damper assembly is installed and pre-adjusted at the factory prior to dryer shipment. However, the sail switch adjustment must be checked to assure that this important safety control is functioning (for GAS and ELECTRIC MODELS ONLY). 5. Check bolts, nuts, screws, terminals, and fittings for tightness. 6. Be sure all gas shut-off valves are in the open position (for GAS MODELS ONLY). 7. Be sure ALL back guard panels and service box covers have been replaced. 8. Make sure the lint coop support bracket has been removed. 9. Check the lint door to assure that it is closed and secured in place. IMPORTANT: If during installation the lint door safety chain was disconnected, it must be reconnected or personal injury may result. 10. Rotate the basket (tumbler) by hand to be sure it moves freely. 11. Check to insure ALL steam shut-off valves are open (for STEAM MODELS ONLY). 12. Check to insure that a clean, dry, regulated air supply (80 PSI) is on the dryer (for STEAM MODELS with DAMPER SYSTEM ONLY). 35 T. Preoperational Test 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. 1. Turn on electric power to dryer. 2. Refer to the Operating Instructions for starting your particular model dryer. 3. Gas Dryers a. When a gas dryer is first started (during initial startup), it has a tendency not to ignite on the first ignition attempt. This is because the gas supply piping is filled with air, So it may take a few minutes for the air to be purged from the lines. NOTE: During the purging period, check to be sure that ALL gas shut-off valves are open. NOTE: Gas dryers are equipped with a Direct Spark Ignition (DSI) system which has internal diagnostics. If ignition is not established after three (3) attempts, the heat circuit in the DSI module will lock out until it is manually reset. To reset the DSI system, open and close the main door and restart the dryer. b. A gas pressure test should be taken at the gas valve pressure tap of each dryer to assure that the water column pressure is correct and consistent. NOTE: Water column pressure requirements (measured at the pressure tap on the gas valve body): Natural Gas — 3.5 to 4.0 Inches Water Column L.P. Gas---------------11.0 Inches Water Column 36 IMPORTANT: There is no regulator provided in an L.P. dryer. The water column pressure must be regulated at the source (L.P. tank) or an external regulator must be added to each dryer. 4. Make a complete operational check of ALL safety related circuits: a. Door switch(es) b. Hi-limit thermostat c. Cycling thermostat d. Sail switch (for GAS and ELECTRIC MODELS ONLY) NOTE: The sail switch can be checked for proper operation by opening the lint door while the heating circuit (gas burner/electric oven) is active (on). The heating unit should shut off within a few seconds. If not, make necessary adjustments to sail switch. 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. 6. The dryer should be operated through one (1) complete cycle to assure that no further adjustments are necessary and that ALL components are functioning properly. IMPORTANT: The dryer basket (tumbler) is treated with a protective coating. ADC suggests tumbling old c...
