manual abstract
There are many different types of flex hose on the market today. These are manufactured from materials such as polyethylene, PVC, cloth hose dipped in rubber and even metal, including steel and aluminum. There are also many kinds of pure plastic flexible hose, such as non-perforated drainage type hose and dryer vent hose. Drainage type hose, while being economical, does not quite have the flexibility required for dust collection. The inside of the duct is also deeply corrugated and can increase the static pressure loss by as much as 50% over smooth wall duct. Dryer vent hose, while being completely flexible, is non-resistant to abrasion and has a tendency to collapse in a negative pressure system. If using flex-hose, you should choose one of the many types that are designed specifically for the movement of solid particles, i.e. dust, grains G8027 1 HP Dust Collector and plastics. However, the cost of specifically designed flexible duct can vary greatly. Grizzly offers polyethylene hose, which is well suited for the removal of particulate matter, especially sawdust, since it is durable and completely flexible. Polyethylene is also very economical and available in a wide variety of diameters and lengths for most applications. Duct Grounding Plastic flex-hose is an insulator, and dust particles moving against the walls of the hose creates a static electrical build up. This charge will build until it discharges to a ground. If a grounding medium is not available to prevent static electrical build up, the electrical charge will arc to the nearest grounded source. This electrical discharge may cause an explosion and subsequent fire inside the system. To protect against static electrical build up inside a non-conducting duct, a bare copper wire should be placed inside the duct along its length and grounded to the dust collector. You must also confirm that the dust collector is continuously grounded through the electrical circuit to the electric service panel. \Awarning Always guard against static electrical build up by grounding all dust collection lines. Be sure that you extend the bare copper wire down all branches of the system. Do not forget to connect the wires to each other with wire nuts when two branches meet at a “Y” or “T” connection. Ensure that the entire system is grounded. If using plastic blast gates to direct air flow, the grounding wire must be jumped (Figure 15) around the blast gate without interruption to the grounding system. Figure 15. Ground jumper wire when using plastic blast gates or elbows and metal duct. We also recommend wrapping the outside of all plastic ducts with bare copper wire to ground the outside of the system against static electrical build up. Wire connections at Y’s and T’s should be made with wire nuts. Attach the bare ground wire to each stationary woodworking machine and attach the dust collector frame with a ground screw as shown in Figure 16. Ensure that each machine is continuously grounded to the grounding terminal in your electric service panel. -16- G8027 1 HP Dust Collector SECTION 4: OPERATION Operation Safety Test Run ! ll ▲warning Disconnect power to the machine when performing any maintenance, assembly or adjustments. Failure to do this may result in serious personal injury. 'fi ▲WARNING Keep loose clothing rolled up and out of the way of machinery and keep hair pulled back. ▲warning Wear safety glasses during the entire operations process. Failure to comply may result in serious personal injury. ▲CAUTION Always wear a respirator when operating your dust collector. This machine circulates sawdust dust which may cause allergic reactions or respiratory problems. Once assembly is complete and adjustments are done to your satisfaction, you are ready to test run the machine. Turn on the power supply at the main panel. Turn the dust collector ON. Make sure that your finger is poised on the toggle switch just in case there is a problem. The dust collector should run smoothly, with little or no vibration or rubbing noises. Strange or unnatural noises should be investigated and corrected before operating the machine further. If you cannot easily locate the source of an unusual noise or vibration, contact our service department for help. General Operating your Model G8027 is simple and straightforward. Move the dust collector to the machine location, connect the duct, connect the ducting ground, and you are ready to begin. ▲caution DO NOT use the dust collector for any other purpose besides collecting dust from connected woodworking machines. A dust collector should NEVER be used as an air cleaner. For safest use, wear a respirator and use an air cleaner in addition to the dust collector.
