Start-Up, Operation, andMaintenance InstructionsSAFETY CONSIDERATIONSAbsorption liquid chillers provide safe and reliable serv-ice when operated within design specifications. When op-erating this equipment, use good judgment and safetyprecautions to avoid damage to equipment and propertyor injury to personnel.Be sure you understand and follow the procedures andsafety precautions contained in the machine instructionsas well as those listed in this guide.DO NOT USE OXYGEN or air to purge lines, leak test, orpressurize a machine. Use nitrogen.NEVER EXCEED specified test pressures. For the 16JT chiller,the maximum pressure is 12 psig (83 kPa).WEAR goggles and suitable protective clothing when han-dling lithium bromide, octyl alcohol, inhibitor, lithium hy-droxide, and hydrobromic acid. IMMEDIATELY wash anyspills from the skin with soap and water. IMMEDIATELYFLUSH EYES with water and consult a physician.DO NOT USE eyebolts or eyebolt holes to rig machine sec-tions or the entire assembly.DO NOT work on high-voltage equipment unless you are aqualified electrician.DO NOT WORK ON electrical components, including con-trol panels or switches, until you are sure ALL POWER ISOFF and no residual voltage can leak from capacitors or solid-state components.LOCK OPEN AND TAG electrical circuits during servic-ing. IF WORK IS INTERRUPTED, confirm that all circuitsare deenergized before resuming work.NEVER DISCONNECT safety devices or bypass electric in-terlocks and operate the machine. Also, never operate themachine when any safety devices are not adjusted and func-tioning normally.DO NOT syphon lithium bromide or any other chemical bymouth.BE SURE all hydrogen has been exhausted before cuttinginto purge chambers. Hydrogen mixed with air can explodewhen ignited.WHEN FLAMECUTTING OR WELDING on an absorp-tion machine, some noxious fumes may be produced. Ven-tilate the area thoroughly to avoid breathing concentrated fumes.DO NOT perform any welding or flamecutting to a machinewhile it is under a vacuum or pressurized condition.NEVER APPLY an open flame or live steam to a refrigerantcylinder. Dangerous overpressure can result. When neces-sary to heat a cylinder, use only warm (110 F [43 C]) water.DO NOT REUSE disposable (nonreturnable) cylinders or at-tempt to refill them. It is DANGEROUS AND ILLEGAL.When cylinder is emptied, evacuate remaining gas pressure,loosen the collar and unscrew and discard the valve stem.DO NOT INCINERATE.DO NOT ATTEMPT TO REMOVE fittings, covers, etc., whilemachine is under pressure or while machine is running.DO NOT climb over a machine. Use platform, catwalk, orstaging. Follow safe practices when using ladders.DO NOT STEP ON machine piping. It might break or bendand cause personal injury.USE MECHANICAL EQUIPMENT (crane, hoist, etc.) tolift or move inspection covers or other heavy components.Even if components are light, use such equipment when thereis a risk of slipping or losing your balance.VALVE OFF AND TAG steam, water, or brine lines beforeopening them.DO NOT LOOSEN waterbox cover bolts until the water boxhas been completely drained.DO NOT VENT OR DRAIN waterboxes containing indus-trial brines, liquid, gases, or semisolids without permissionof your process control group.BE AWARE that certain automatic start arrangements canengage starters. Open the disconnects ahead of the startersin addition to shutting off the machine or pump.USE only repaired or replacement parts that meet the coderequirements of the original equipment.DO NOT ALLOW UNAUTHORIZED PERSONS to tamperwith machine safeties or to make major repairs.PERIODICALLY INSPECT all valves, fittings, piping, andrelief devices for corrosion, rust, leaks, or damage.PROVIDE A DRAIN connection in the vent line near eachpressure relief device to prevent a build-up of condensate orrain water.IMMEDIATELY wipe or flush the floor if lithium bromideor octyl alcohol is spilled on it.16JT60 HzDouble-Effect Hermetic Absorption Liquid ChillersUnits 810-880, 080-150, 080L-150LManufacturer reserves the right to discontinue, or change at any time, specifications or designs without notice and without incurring obligations.Book 2Tab 5bPC 211 Catalog No. 531-607 Printed in U.S.A.
