19X RVHermetic Centrifugal Liquid Chillerswith PIC III Controls50/60 HzHFC-134aStart-Up, Operation, and Maintenance InstructionsSAFETY CONSIDERATIONSCentrifugal liquid chillers are designed to provide safeand reliable service when operated within design speci-fications. When operating this equipment, use goodjudgment and safety precautions to avoid damage toequipment and property or injury to personnel.Be sure you understand and follow the proceduresand safety precautions contained in the chiller instruc-tions as well as those listed in this guide.DO NOT VENT refrigerant relief valves within a buikting. Outletfrom rupture disc or relief valve must be vented outdoors in accor-dance with the latest edition of ANSI/ASHRAE 15 (AmericanNational Standards Institute/American Society of Heating, Refrigera-tion, and Air Conditioning Engineers). The accumulation of refriger-ant in an enclosed space can displace oxygen and cause asphyxiation.PROVIDE adequate ventilation in accordance with ANSI/ASHRAE15, especially for enclosed and low overhead spaces. Inhalation ofhigh concentrations of vapor is hamlfill and may cause heart irregular-ities, nnconsciousness, or death. Misuse can be fatal. Vapor is heavierthan air and rednces the amonnt of oxygen available for breathing.Product causes eye and skin irritation. Decomposition products arehazardous.DO NOT USE OXYGEN to purge lines or to pressurize a chiller forany purpose. Oxygen gas reacts violently with oil, grease, and otherCOlnlllOn substances.NEVER EXCEED specified test pressures, VERIFY the allowabletest pressure by checking the instruction literature and the design pres-sures on the equipment nameplate.DO NOT USE air for leak testing. Use only refrigerant or drynitrogen.DO NOT VALVE OFF any safety device.BE SURE that all pressure relief devices are properly installed andfimctioning before operating any chiller.THERE IS A RISK OF INJURY OR DEATH by electrocution. Highvoltage may be present on the motor leads even though the motor isnot running. Open the power supply disconnect before touchingmotor leads or terminals.DO NOT WELD OR FLAMECUT any refrigerant line or vessel untilall refrigerant (liquM atM V'al)or) has been removed from chiller.Traces of vapor should be displaced with dry air or nitrogen and thework area should be well ventilated. R@'ixemm in contact _Hth ano!)et_flame prodHc_,s toxic gaxes.DO NOT USE eyebolts or eyebolt holes to rig chiller sections or theentire assembly.DO NOT work on high-voltage equipment unless yon are a qualifiedelectrician.DO NOT WORK ON electrical components, including controlpanels, switches, starters, or oil heater until you are sure ALLPOWER IS OFF and no residual voltage can leak from capacitors orsolid-state components.LOCK OPEN AND TAG electrical circuits during servicing. IFWORK IS INTERRUPTED, confirm that all circuits are deenergizedbefore resuming work.AVOID SPILLING liquid refrigerant on skin or getting it into theeyes. USE SAFETY GOGGLES. Wash any spills from the skin withsoap and water. If liqnid refrigerant enters the eyes, IMMEDIATELYFLUSH EYES with water and consult a physician.NEVER APPLY an open flame or live steam to a refrigerant cylinder.Dangerous over pressure can result. When it is necessary to heatrefrigerant, use only warm (110 F D3 C]) water.DO NOT REUSE disposable (nonreturnable) cylinders or attempt torefill them. It is DANGEROUS AND ILLEGAL. When cylinder isemptied, evacuate remaining gas pressure, loosen the collar andunscrew and discard the valve stem. DO NOT INCINERATE.CHECK THE REFRIGERANT TYPE before adding refrigerant tothe chiller. The introdnction of the wrong refrigerant can causedamage or malfunction to this chiller.Operation of this equipment with refrigerants other than thosecited herein should comply with ANSI/ASHRAE 15 (latest edition).Contact Carrier for timber information on use of this chiller with otherrefrigerants.DO NOT ATTEMPT TO REMOVE fittings, covers, etc., whilechiller is under pressure or while chiller is running. Be sum pressure isat 0 psig C0kPa) before breaking any refrigerant connection.CAREFULLY INSPECT all relief devices, rupture discs, and otherrelief devices AT LEAST ONCE A YEAR. If chiller operates in acorrosive atmosphere, inspect the devices at morn frequent intervals.DO NOT ATTEMPT TO REPAIR OR RECONDITION any reliefdevice when corrosion or build-up of foreign material (rust, dirt, scale,etc.) is found within the valve body or mechanism. Replace thedevice.DO NOT install relief devices 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 actas projectiles.DO NOT STEP on refrigerant lines. Broken lines can whip about andrelease refrigerant, causing personal injury.DO NOT climb over a chiller. Use platform, catwalk, or staging.Follow safe practices when using ladders.USE MECHANICAL EQUIPMENT (crone, hoist, etc.) to liltor move inspection covers or other heax.y components. Even ifcomponents are light, use mechanical equipment when there is a riskof slipping or losing your balance.BE AWARE that certain automatic start arrangements CANENGAGE THE STARTER, TOWER FAN, OR PUMPS. Open thedisconnect ahead of the starter, tower fans, or pumps.USE only repair or replacement parts that meet the code requirementsof the original equipment.DO NOT VENT OR DRAIN waterboxes containing industrial brines,liquid, gases, or semisolids withont the permission of your processcontrol group.DO NOT LOOSEN waterbox cover bolts until the waterbox has beencompletely drained.DO NOT LOOSEN a packing gland nut before checking that the nuthas a positive thread engagement.PERIODICALLY INSPECT all valves, fittings, and piping forcorrosion, rest, leaks, or damage.PROVIDE A DRAIN connection in the vent line near each pressurerelief device to prevent a build-up of condensate or rain watecManufacturer reserves the right to discontinue, or change at any time, specifications or designs without notice and without incurring obligations.PC 211 Catalog No. 531-986 Printed in U.S.A.
