Be sure you understand and follow the procedures and safety precautions contained in the machine instructions as well as those listed in this guide. DO NOT USE OXYGEN or air to purge lines, leak test, or pressurize a machine. Use nitrogen. NEVER EXCEED specified test pressures. For the 16DF machine, the maximum pressure is 12 psig (83 kPa). For the chilled/hot water and condensing water piping, the maximum pressure is stamped on the machine. WEAR goggles and suitable protective clothing when handling lithium bromide, octyl alcohol, inhibitor, lithium hydroxide, and hydrobromic acid. IMMEDIATELY wash any spills from the skin with soap and water. IMMEDIATELY FLUSH EYES with water and consult a physician. DO NOT USE eyebolts or eyebolt holes to rig maching sec tions or the entire assembly. DO NOT work on high-voltage equipment unless you are a qualified electrician. DO NOT WORK ON electrical components, including control panels or switches, until you are 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 deenergized before resuming work. NEVER DISCONNECT safety devices or bypass electric interlocks and operate the machine. Also, never operate the machine when any safety devices are not adjusted and functioning normally. DO NOT REPEAT unsuccessful ignition attempts or restart after flame failure without assurance that post-purge and pre- purge have eliminated combustible gas or oil vapors from the combustion chamber. DO NOT EVER ATTEMPT IGNITION of a burner if there is shutdown leakage of gas or oil through the fuel shutoff valves or from the fuel lines. DO NOT syphon lithium bromide or any other chemical by mouth. BE SURE all hydrogen has been exhausted before cutting into pure chambers. Hydrogen mixed with air can explode when ignited. WHEN FLAMECUTTING OR WELDING on an absorption machine, some noxious fumes may be produced. Ventilate the area thoroughly to avoid breathing concentrated fumes. DO NOT perform any welding or flamecutting to a machine while it is under a vacuum or pressurized condition. NEVER APPLY an open flame or live steam to a refrigerant cylinder. Dangerous overpressure can result. When necesary to heat a cylinder, use only warm (110 F [43 C]) water. DO NOT REUSE disposable (nonreturnable) cylinders or attempt to refill them. It is DANGEROUS AND ILLEGAL. When cylinder is emptied, bleed off remaining gas pressure, loosen the collar and unscrew and discard the valve stem. DO NOT INCINERATE. DO NOTATTEMPTTO REMOVE fittings, covers, etc., while machine is under pressure or while machine is running. DO NOT OPERATE or pressurize a machine without all cover plates or bolts in place. DO NOT climb over a machine. Use platform, catwalk, or staging. Follow safe practices when using ladders. DO NOT STEP ON machine piping. It might break or bend and cause personal injury. 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. VALVE OFF AND TAG steam, water, or brine lines before opening them. DO NOT LOOSEN water box cover bolt until the water box has been completely drained. DO NOT VENT OR DRAIN water boxes containing industrial brines, liquid, gases, or semisolids without permission of your process control group. BE AWARE that certain automatic start arrangements can engage starters. Open the disconnects ahead of the starters in addition to shutting off the machine or pump. INVESTIGATE THE CAUSE of flame failure or any other safety shutdown before attempting a restart. KEEP EYES sufficiently away from sight tubes or burner openings, and wear a protective shield or safety glasses when viewing a burner flame. USE only repaired or replacement parts that meet the code requirements of the original equipment. DO NOT ALLOW UNAUTHORIZED PERSONS to tamper with burner equipment or machine safeties, or to make major repairs. PERIODICALLY INSPECT all valves, fittings, piping, and relief devices 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. IMMEDIATELY wipe or flush the floor if lithium bromide or octyl alcohol is spilled on it. BE SURE combustion air inlets to the equipment room are open and clear of any blockage. Manufacturer reserves the right to discontinue, or change at any time, specifications or designs without notice and without incurring obligations. Book 2 PC 211 Catalog No. 531-602 Printed in U.S.A.
