Resumen del manual


In a severe dirty operation, the blower impeller should be cleaned with a wire brush to prevent an accumulation of foreign matter that could result in blower unbalance After cleaning impeller, inspect for possible cracks or excessive wear, which can cause unbalance. DO NOT USE AN IMPELLER THAT IS CRACKED OR EXCESSIVELY WORN; REPLACE IT WITH A NEW IMPELLER. MOTOR MAINTENANCE: Removing dust and dirt: Blow off motor with low pressure air to remove dust or dirt. Air pressure above 50 P.S.I. should not be used as high pressure may damage insulation and blow dirt under loosened tape. The operator performing this cleaning function should always wear eye protective goggles. Dust can cause excessive insulation temperatures. SAFETY FEATURE All Dust Collectors have a safety guard at the discharge of the blower housing. This guard is for your safety. Do not remove this guard for any reason. DISCONNECT ALL UNITS FROM POWER SOURCE BEFORE ATTEMPTING ANY MAINTENANCE. TROUBLE SHOOTING GUIDE WARNING: DISCONNECT UNIT FROM POWER BEFORE TROUBLE SHOOTING TROUBLE!! WHAT’S WRONG? WHAT TO DO . . . Unit will not operate. Low suction or flow rate. /' z 1. Improper electrical connection. 2. Blower wheel loose. 1. Incorrect rotation. 2. Suction hose too long. 1. Turn power off - assure unit is wired per instructions. 2. Disconnect power cord. Turn unit over & spin wheel by hand. Reposition and tighten set screws if necessary. 1. Turn unit off and observe motor cooling wheel rotation as it stops. Rewire correctly if necessary. 2. Place unit closer to dust source & shorten hose. 5 CENTRAL DUST COLLECTION SYSTEMS The model 50-181 2 H.P. dust collector is widely used to power small centraLdust collection systems. Model 50-182 may be used if three phase power is available. NOTE: Model 50-180 should not be used for multi-unit central system hook-ups. The following steps will assist in designing and building a convenient space-saving central collection system. DESIGN STEPS (Applicable ONLY to Delta Two Stage Collectors) 1. Determine the Equivalent Length for each duct run. A “run” is the duct going directly from each tool to the «»Hector; several different runs may use parts of the same branch and main ducts. Equivalent length is determined as follows: Smooth wall pipe (metal or plastic) - actual length' Wire reinforced flexible hose - 150% actual length Direction change equivalent lengths: • Curved 90° Elbow (include hose bends) = 10 feet (45° = 5 feet) • Sharp 90° Bend (Tee joint or Elbow) = 20 feet • Special Y Branch Tee (including required 45° Elbow) = 10 feet Add together the component equivalent lengths for each run to obtain its total equivalent length. (Do not be concerned with the total length of the entire duct system.) 2. Determine Air Flow; (use only 4" or 5" pipe for duct.) The maximum allowable equivalent length of either size duct in each duct run is 100 feet; 120 feet with Model 50-182*. Use the same diameter duct throughout the system. Air flow at any duct length can be calculated from this table: 3. DUCT PIPE SELECTION Air flow of 350-550 CFM provides the best dust collection at any woodworking tool. Five inch duct is optimum, and is available in metal furnace pipe. Plastic pipe is easier to install, but is available only in 4" diameter and MUST BE ASSEMBLED WITH AN INTERNAL GROUND WIRE to conduct away potentially explosive static charges. Metal pipe must be sealed with silicone sealant at all joints. 4. TOOL AIR INLET LIMITATIONS Branch ducts can be attached to one main duct and run to many different tools. However, air must flow at only one tool at a time to ensure adequate dust collection. Additional tool inlets must be plugged or slide gates installed to limit the air flow to only one tool. (Do not use a damper to close off a duct.) There is no limit to the number of branch runs in a system as long as each run does not exceed the maximum length, and air flow is limited to one tool at a time. Built-in (on tools) dust collection hoods (or other inlets) which have an inlet opening of less than 4", will restrict air flow and cause chips to drop out in the duct. This will not be a problem, however, if another full size inlet in the same duct run is opened periodically to provide a blast of air to flusfi out the duct. Be sure the second inlet (which may be a full size inlet at another tool) is located farther away from the collector than the undersize inlet. Shop Duct Layout Dust Collector Model Duct Size Max.
