When operating this equipment, use good judgment and safety precautions to avoid damage to equipment and property or injury to personnel. Be sure you understand and follow the procedures and safety precautions contained in the machine instructions as well as those listed in this guide. A DANGER DO NOT USE OXYGEN to purge lines or to pressurize a machine for any purpose. Oxygen gas reacts violently with oil, grease and other common substances. NEVER EXCEED specified test pressures. VERIFY the allowable test pressure by checking the instruction literature and the design pressures on the equipment nameplate. DO NOT VALVE OFF any safety device. BE SURE that all pressure relief devices are properly installed and functioning before operating any machine. A WARNING DO NOT USE eyebolts or eyebolt holes to rig machine sections or the entire assembly. DO NOT woik on high voltage equipment unless you are a qualified electrician DO NOT WORK ON electrical components, including control panels, switches, starters or oil heater until you aie sure ALL POWER IS OFF and no residual voltage can leak from capacitors or solid-state components LOCK OPEN AND TAG electrical circuits during servicing. IF WORK IS INTERRUPTED, confirm that all circuits are de-energized before resuming work. DO NOT syphon refrigerant by mouth. AVOID SPILLING liquid refrigerant on skin or getting it into the eyes USE SAFETY GOGGLES. Wash any spills from the skin with soap and water. If any enters the eyes, IMMEDIATELY FLUSH EYES with water and consult a physician. NEVER APPLY an open flame or live steam to a refrigerant cylinder. Dangerous overpressure can result. When necessary to heat lefrigerant, use only warm (110F/43 C) water DO NOT REUSE disposable (nonreturnable) cylinders nor attempt to refill them. It is DANGEROUS AND ILLEGAL. When cylinder is emptied, evacuate remaining gas pressure, loosen the collar and unsciew and discard the valve stem. DO NOT INCINERATE. CHECK THE REFRIGERANT TYPE before charging machine. High pressure refrigerant in a low pressure machine can cause vessels to rupture if the relief devices cannot handle the refrigerant volume. DO NOT ATTEMPT TO REMOVE fittings, covers, etc. while machine is under pressure or while machine is running. Be sure pressure is at zero psig before breaking any refrigerant connection. CAREFULLY INSPECT all relief valves, rupture discs and other relief devices AT LEAST ONCE A YEAR. If machine operates in a corrosive atmosphere, inspect the devices at more frequent intervals. DO NOT ATTEMPT TO REPAIR OR RECONDITION any relief valve when corrosion or build-up of foreign material (rust, dirt, scale, etc.) is found within the valve body or mechanism. Replace the valve. DO NOT VENT refrigerant relief valves within a building, refer to ANSIB9.1. The accumulation of refrigerant in an enclosed space can displace oxygen and cause asphyxiation. DO NOT install relief valves in series or backwards. USE CARE when working near or in line with a compressed spring. Sudden release of the spring can cause it and objects in its path to act as projectiles. A CAUTION DO NOT STEP on refrigerant lines. Broken lines can whip about and cause personal injury. DO NOT climb over a machine. Use platform, catwalk 01 staging. Follow safe practices when using ladders. USE MECHANICAL EQUIPMENT (crane, hoist, etc ) to lift or move inspection covers or other heavy components. Even if components are light, use such equipment when there is a risk of slipping or losing your balance. DO NOT WELD OR FLAME CUT any refrigerant line or vessel until all refrigerant has been transferred from the vessel to storage. BE AWARE that certain automatic start arrangements CAN ENGAGE THE STARTER. Open the disconnect ahead of the starter in addition to shutting off the machine or pump USE only lepair or replacement parts that meet the code requirements of the original equipment DO NOT VENT OR DRAIN water boxes containing industrial brines, liquid, gases or semisolids without permission of youi Process Control Group. DO NOT LOOSEN water box cover bolts until the water box has been completely drained. DOUBLE-CHECK that coupling nut wrenches, dial indicators or other items have been removed before rotating any shafts. DO NOT LOOSEN a packing gland nut before checking that the nut has a positive thread engagement. PERIODICALLY INSPECT all valves, fittings and piping for corrosion, rust, leaks or damage PROVIDE A DRAIN connection in the vent line near each pressure relief device to prevent a build-up of condensate or rain water.
