GENERAL INFORMATION ELECTRICAL REQUIREMENTS 220 VAC 50/60 HZ 20 AMP DEDICATED LINE NEMA L620R RECEPTACLE IMPORTANT INFORMATION The use of heat to accelerate drying may require more frequent lubrication and/or use of a high temperature lubricant in the delivery of the press. Please consult your press manufacturer for specific recommendations. SAFETY INFORMATION The Tempest® Dryer contains high voltage and hot surfaces.
GENERAL INFORMATION HOT AIR VS INFRARED WHAT MAKES TEMPEST® WORK Although the technology behind the Tempest® dryer was significant enough to be awarded the GATF Intertech Award, it is by no means new. In fact, thermistors have been in use for many years. They were originally used in motors and other devices as a heat controller and later used in refrigeration to turn compressors on and off. It is only in the last 10 years or so that thermistors have been used as a heater.
GENERAL INFORMATION IR dryers use very high temperatures and a fixed amount of electricity. One of the drawbacks of using a very hot heat source is that heat wants to travel from a very high temperature to a very low temperature. In other words, the heat generated from an IR dryer will travel to the press wall and attempt to increase its temperature because it is cooler than the heat produced by the IR dryer.
INSTALLATION 1 DISCONNECT THE POWER TO THE PRESS BEFORE BEGINNING INSTALLATION. Remove the two large side covers over the main framework of the press (one at OPS and one at NOPS) and the NOPS cover at the delivery end of the press. For an easier installation, you may also want to remove the two guards on the delivery end of the press. 2 NOTE: Do not cut the hose if the press is equipped with an Airtech sprayer. Cut the sprayer hose about halfway between the hopper and the spray bar.
INSTALLATION 4 5 Remove the chain guide (subject arrow) at the OPS & NOPS sides of the press. Install the mounting bracket and new chain guide using M5 X 16MM cap head bolts and lock washers (subject arrow) as shown at the OPS & NOPS. Leave the bolts loose so the position of the dryer can be moved up and down. The bolts thread into the same holes that held the original chain guides.
INSTALLATION 6 Note: If the press is equipped with an Airtech sprayer, you must remove the spray bar from the dryer before installing it in the press.To remove the spray bar from the dryer, remove the three screws on the top of the dryer. Set the dryer on the brackets with the cable exiting at the NOPS. Run the cable under the mounting bracket (subject arrow, left picture) and through the large hole in the side frame (subject arrow, lower picture) directly under the mounting bracket.
INSTALLATION 8 9 Position the dryer so it clears the gripper opening mechanism on all three delivery gripper bars. The arm must clear both the top and bottom of the dryer. The photo shows the arm clearing the top of the dryer (subject arrow). After positioning the dryer, tighten the bolts holding the mounting brackets to the press frame and the bolts holding the dryer to the mounting brackets. NOTE: If the press is equipped with an Airtech sprayer, proceed to step 11.
INSTALLATION 10 11 12 Connect the two hoses together using the "Y" connector (left hand subject arrow). Connect the Tempest® Spray line to the press spray hopper line using the reducer (right hand subject arrow). Attach the exhaust fan/manifold assembly to the center of the delivery guard as shown. Make sure that the arrow on the fan is pointing toward the guard (out of the press) and that the wires are routed toward the NOPS of the press.
INSTALLATION 13 14 15 Attach the microswitch cable assembly to the microswitch's installed in step 12. See diagram for proper connection. Find a suitable location for the main Tempest electrical box on the NOPS of the press. Route the exhaust fan cable (this cable has female pins in the connector on the end) into the delivery and connect it to the exhaust fan installed in a previous step.
INSTALLATION 16 17 18 Remove one of the two screws that attach the guard prop to the delivery guard on the NOPS. Install the supplied longer M4 screw in its place and using the original nut secure the provided cable clamp (subject arrow) to the underside of the guard. Make sure you have the exhaust fan cable going through the clamp before securing it to the guard. Place the larger heat shield in the delivery as shown.
INSTALLATION 19 Use the provided zip ties to secure all loose cables. See the back of the manual for a complete electrical system diagram. Replace all covers and guards. Attach the supplied multiple power cord caution label to the press side NOPS cover.
OPERATION & MAINTENANCE HOW DRYING IS ACCELERATED WITH TEMPEST® Tempest® creates a two-step drying process when used with oil-base inks. These steps are: 1. Skinning the surface of the ink with the initial blast of hot air to prevent set off. 2. Accelerating the final drying process approximately 20o F over the cold stack temperature in the feeder. Heat accelerates the drying process, called oxidation and reduction, of oil-based inks.
OPERATION & MAINTENANCE NORMAL OPERATION Pressing the HEAT switch will illuminate both the green and yellow LEDs on the remote control unit. The green LED indicates that the fans (both dryer and exhaust fans if so equipped) are running while the yellow LED indicates that the dryer is armed and the heat will come on automatically when the press goes on impression. When the press does go on impression, the green LED will illuminate indicating that the heat is on.
OPERATION & MAINTENANCE FACTORS THAT EFFECT DRYING 1. 2. 3. 4. Speed of the press. Amount of ink coverage and color. Type of stock being printed. Initial temperature of paper. In time and with practice you will learn which settings are best for your particular shop. KEYS TO REMEMBER 1. The Tempest® takes about 12 sheets to come up to full power. The dryer remains on as long as paper is being fed. It does not cycle like an infrared dryer. 2.
OPERATION & MAINTENANCE SAFETY REQUIREMENTS 1. Accel equipment should only be installed by an authorized dealer or distributor. 2. Only use ink or varnish that are explosion safe when used with the Tempest®. (Refer to the MSDS of ink in use) 3. Make sure to visually check the delivery that the cables in use are not causing a dangerous situation while in operation. 4.
