Operating Instructions 5 Forklift Safety 1. Make sure lift operator stays aware while moving compressor. 2. Be sure load is secure and well balanced before moving the compressor. 3. Make sure forks are fully engaged and level before lifting or moving compressor. 4. Keep load as low as possible and observe safe operating practices. Lifting Safety 1. Carefully inspect all lifting equipment and make sure it is in good condition. Rated capacity should exceed compressor weight. Make sure lifting hook has a functional safety latch or equivalent and is properly attached to lifting feature. 2. Make sure lifting points are in good condition and tighten any loose nuts or bolts before lifting. 3. Use provided lifting feature or appropriate sling. A sling must be used when moving compressor with a helicopter or other air-borne equipment. Be sure to follow OSHA standards 29 CFR 1910 Subpart N. 4. Use guide or equivalent to prevent twisting or swinging of the compressor while it is in the air and NEVER attempt to lift in high winds. Keep compressor as low to the ground as possible. 5. Keep persons away and make sure noone is under the compressor while it is lifted. 6. Only use lifting features provided for entire com- pressorpackage.NEVER useboltsorotherhookson invididual components to move the compressor. 7. Make sure to put compressor on a level surface that can support the weight of the compressor and loading equipment. Do not operate unit if damaged during shipping handling or use. Damage may result in bursting and cause injury or property damage. Installation Area 1. Install compressor in a clean dry and well-lit area. Be sure installation area can maintain a temperature range between 35˚ - 110˚ F. If ambient temperature drops below 32˚F be sure to protect safety/relief valves and drain valves from freezing. NEVER operate compressor with temperatures below 15˚F or above 125˚F. 2. Allow sufficient space around compressor for maintenance access and adequate airflow. Mount unit with pulley towards wall and leave a minimum of 15 inches of clearance. 3. Use shims to level compressor if installation area is not flat. This will avoid excessive vibration and premature pump wear. DO NOT install compressor in boiler room paint spray room or area where sandblasting occurs. Make sure inlet air is away from exhaust fumes or other toxic noxious or corrosive fumes or substances. 4. If acid is used in operating environment or air is dust laden pipe intake to outside fresh air. Increase pipe size by one size for every 20 feet of run. Be sure to install protective hood around intake filter. 5. In operating environments where excessive wa- ter oil dirt acid or alkaline fumes are present a TEFC totally enclosed fan cooled motor is recommended. Check nameplate for motor type. 6. Insulate cold water or other low temperature pipes that pass overhead to avoid condensation dripping on compressor which could cause rust and/or motor shorting. Piping Safety Steps 1. Install appropriate flow-limiting valves as nec- essary according to pipe sizes used and run lengths. This will reduce pressure in case of hose failure per OSHA Standard 29 CFR 1926.302b7. 2. Flow-limiting valves are listed by pipe size and rated CFM. Select appropriate valves accordingly in accordance with the manufacturer’s recommen- dations.
