They may not be reproduced, inwhole or in part, without prior written authorisation froman Authorised Johnson Controls representative.1-2Structural support of the unit must be provided asindicated in these instructions. Failure to provide propersupport may result in injury to the operator, or damage tothe equipment.Mechanical StrengthThe unit is not designed to withstand loads or stressesfrom adjacent equipment, pipework or structures.Additional components must not be mounted on theunit. Any such extraneous loads may cause structuralfailure and may result in injury to the operator, ordamage to the equipment.General AccessThere are a number of areas and features which may bea hazard and potentially cause injury when working withthe unit unless suitable safety precautions are taken. Itis important to ensure access to the unit is restricted tosuitably qualified persons who are familiar with thepotential hazards and precautions necessary for safeoperation and maintenance of equipment containinghigh temperatures, pressures and voltages.Pressure SystemsThe unit contains refrigerant vapour and liquid underpressure, release of which can be a danger and causeinjury. The user should ensure that care is taken duringinstallation, operation and maintenance to avoiddamage to the pressure system. No attempt should bemade to gain access to the component parts of thepressure system other than by suitably trained andqualified personnel.
035-21786-100 Rev. 1 (0909)Electrical1.8The unit must be earthed. No installation ormaintenance work should be attempted on electricalequipment without first switching off, isolating andlocking-off the power supplies. Work on live equipmentmust only be carried-out by suitably trained andqualified personnel. No attempt should be made to gainaccess to inside of the control panel, wiring or otherelectrical enclosures during normal operation of the unit.The following labels are fixed to each unit to giveinstruction, or to indicate potential hazards which mayexist.Refrigerants and OilsRefrigerants and oils used in the unit are generallynon-toxic, non-flammable and non-corrosive, and poseno special safety hazards. Use of gloves and safetyglasses are, however, recommended when working onthe unit. Build up of refrigerant vapour, from a leak forexample, does pose a risk of asphyxiation in confined orenclosed spaces and attention should be given to goodventilation. For more comprehensive information onsafety precautions for use of refrigerants and oils, referto the Materials Safety Data tables provided.High Temperature and Pressure CleaningHigh temperature and pressure cleaning methods (e.g.steam cleaning) should not be used on any part of thepressure system as this may cause operation of thepressure relief device(s).

Unlikely to be hazardous by skin absorption.Thaw affected areas with water. Remove contaminated clothing carefully — may adhere to skin incase of freeze burns. Wash affected areas with plenty of warm water. If symptoms occur (irritationor blistering) obtain medical attention.In contact with eyesVapour has no effect. Liquid splashes or spray may cause freeze burns. Immediately irrigate witheyewash solution or clean water for at least 10 minutes. Obtain immediate medical attention.IngestedHighly unlikely to occur — but should this occur freeze burn will occur. Do not induce vomiting.Provided patient is conscious, wash mouth with water and give about 250 ml (0.5 pint) to drink.Obtain immediate medical attention.InhalationHigh atmospheric concentrations may have an anaesthetic effect, including loss of consciousness.Very high exposures may cause an abnormal heart rhythm and prove suddenly fatal.At higher concentration there is a danger from asphyxiation due to reduced oxygen content ofatmosphere. Remove patient to fresh air, keep warm and at rest. Administer oxygen if necessary.Apply artificial respiration if breathing has ceased or shows signs of failing. In event of cardiacarrest apply external cardiac massage. Obtain immediate medical attention.Further medical advice Symptomatic and supportive therapy is indicated. Cardiac sensitisation has been described whichmay, in the presence of circulating catecholamines such as adrenalin, give rise to cardiacarrhythmia’s and subsequent arrest following exposure to high concentrations.Long term exposureA lifetime inhalation study in rats has shown that exposure to 50,000 ppm resulted in benigntumours of the testis. This is not considered to be of relevance to humans exposed toconcentrations at or below the occupational exposure limit.Occupational exposure Recommended limit: 1000 ppm v/v - 8 hr TWA.limitsStabilityNot specified.Conditions to avoidUse in presence of naked flames, red hot surfaces and high moisture levels.May react violently with sodium, potassium, barium and other alkali and alkaline earth metals.Hazardous reactionsIncompatible materials: Magnesium and alloys containing more then 2% magnesium.HazardousHalogen acids by thermal decomposition and hydrolysis.decompositionproductsGeneral precautionsAvoid inhalation of high concentrations of vapours. Atmospheric concentrations should beminimised and kept as low as reasonably practicable below the occupational exposure limit. Thevapour is heavier than air and collects at low level and in confined areas. Ventilate by extraction atlowest levels.Respiratory protection Where doubt exists on atmospheric concentration, HSE approved breathing apparatus should beworn. This should be self contained or of the long breather type.StorageKeep containers dry and in a cool place away from fire risk, direct sunlight, and all sources of heatsuch as radiators. Keep at temperatures not exceeding 45 C.Protective clothingWear overalls, impervious gloves and goggles/face protection.Spill/leak procedureEnsure suitable personal protective clothing and respiratory protection is worn. Provided it is safeto do so, isolate the source of the leak. Allow small spillage’s to evaporate provided there issuitable ventilation.Large spillage’s: Ventilate area. Contain spillage’s with sand, earth or any suitable absorbentmaterial. Prevent liquid from entering drains, sewers, basements and work pits since vapour maycreate a suffocating atmosphere.DisposalBest to recover and recycle. If this is not possible, destruction is to be in an approved facility whichis equipped to absorb and neutralise acids and other toxic processing products.Fire extinguishing data Non-flammable at atmospheric conditions.ContainersFire exposed containers should be kept cool with water sprays. Containers may burst ifoverheated.Fire fighting protective Self contained breathing apparatus and protective clothing must be worn in fire conditions.equipment1-4
