GBOPERATING AND

GBOPERATING AND MAINTENANCE INSTRUCTIONSPlease carefully read theinstructions provided inthis manual before usingthe air conditioning unitThis appliancecontains refrigerantgas R290WARNINGS (for using R290/R32 refrigerant only)• Do not use means to accelerate the defrosting process or to clean, other than those recommended by themanufacturer.• The appliance shall be stored in a room without continuously operating ignition sources (for example: open flames,an operating gas appliance or an operating electric heater).• Do not pierce or burn.• Be aware that the refrigerants may not contain an odour.• Appliance should be installed, operated and stored in a room with a floor area larger than 4 m2.• Compliance with national gas regulations shall be observed.• Keep ventilation openings clear of obstruction.The appliance shall be stored so as to prevent mechanical damage from occurring.• A warning that the appliance shall be stored in a well-ventilated area where the room size corresponds to the roomarea as specified for operation.• Any person who is involved with working on or breaking into a refrigerant circuit should hold a current valid certificatefrom an industry-accredited assessment authority, which authorises their competence to handle refrigerants safelyin accordance with an industry recognised assessment specification.• Servicing shall only be performed as recommended by the equipment manufacturer. Maintenance and repairrequiring the assistance of other skilled personnel shall be carried out under the supervision of the person competentin the use of flammable refrigerants.1. Transport of equipment containing flammable refrigerantsSee transport regulations2. Marking of equipment using signsSee local regulations3. Disposal of equipment using flammable refrigerantsSee national regulations.4. Storage of equipment/appliancesThe storage of equipment should be in accordance with the manufacturer’s instructions.5.Storage of packed (unsold) equipmentStorage package protection should be constructed such that mechanical damage to the equipment inside the packagewill not cause a leak of the refrigerant charge.The maximum number of pieces of equipment permitted to be stored together will be determined by local regulations.6. Information on servicing1) Checks to the areaPrior to beginning work on systems containing flammable refrigerants, safety checks are necessary to ensure that therisk of ignition is minimised. For repair to the refrigerating system, the following precautions shall be complied withprior to conducting work on the system.2) Work procedureWork shall be undertaken under a controlled procedure so as to minimise the risk of a flammable gas or vapour beingpresent while the work is being performed.3) General work areaAll maintenance staff and others working in the local area shall be instructed on the nature of work being carried out.Work in confined spaces shall be avoided. The area around the workspace shall be sectioned off. Ensure that theconditions within the area have been made safe by control of flammable material.18 /

4) Checking for presence of refrigerantThe area shall be checked with an appropriate refrigerant detector prior to and during work, to ensure the technician isaware of potentially flammable atmospheres. Ensure that the leak detection equipment being used is suitable for usewith flammable refrigerants, i.e. non-sparking, adequately sealed or intrinsically safe.5) Presence of fire extinguisherIf any hot work is to be conducted on the refrigeration equipment or any associated parts, appropriate fire extinguishingequipment shall be available to hand. Have a dry powder or CO2 fire extinguisher adjacent to the charging area.6) No ignition sourcesNo person carrying out work in relation to a refrigeration system which involves exposing any pipe work that containsor has contained flammable refrigerant shall use any sources of ignition in such a manner that it may lead to the risk offire or explosion. All possible ignition sources, including cigarette smoking, should be kept sufficiently far away fromthe site of installation, repairing, removing and disposal, during which flammable refrigerant can possibly be releasedto the surrounding space. Prior to work taking place, the area around the equipment is to be surveyed to make surethat there are no flammable hazards or ignition risks. No Smoking signs shall be displayed.7) Ventilated areaEnsure that the area is in the open or that it is adequately ventilated before breaking into the system or conducting anyhot work. A degree of ventilation shall continue during the period that the work is carried out. The ventilation shouldsafely disperse any released refrigerant and preferably expel it externally into the atmosphere.8) Checks to the refrigeration equipmentWhere electrical components are being changed, they shall be fit for the purpose and to the correct specification. At alltimes the manufacturer’s maintenance and service guidelines shall be followed. If in doubt consult the manufacturer’stechnical department for assistance. The following checks shall be applied to installations using flammable refrigerants:The charge size is in accordance with the room size within which the refrigerant containing parts are installed;The ventilation machinery and outlets are operating adequately and are not obstructed;If an indirect refrigerating circuit is being used, the secondary circuit shall be checked for the presence of refrigerant;Marking to the equipment continues to be visible and legible. Markings and signs that are illegible shall be corrected;Refrigeration pipe or components are installed in a position where they are unlikely to be exposed to any substancewhich may corrode refrigerant containing components, unless the components are constructed of materials which areinherently resistant to being corroded or are suitably protected against being so corroded.9) Checks to electrical devicesRepair and maintenance to electrical components shall include initial safety checks and component inspectionprocedures. If a fault exists that could compromise safety, then no electrical supply shall be connected to the circuituntil it is satisfactorily dealt with. If the fault cannot be corrected immediately but it is necessary to continue operation,an adequate temporary solution shall be used. This shall be reported to the owner of the equipment so all parties areadvised.Initial safety checks shall include:That capacitors are discharged: this shall be done in a safe manner to avoid possibility of sparking;That there no live electrical components and wiring are exposed while charging, recovering or purging the system;That there is continuity of earth bonding.7. Repairs to sealed components1) During repairs to sealed components, all electrical supplies shall be disconnected from the equipment being workedupon prior to any removal of sealed covers, etc. If it isabsolutely necessary to have an electrical supply to equipmentduring servicing, then a permanently operating form of leak detection shall be located at the most critical point to warnof a potentially hazardous situation.2) Particular attention shall be paid to the following to ensure that by working on electrical components, the casing isnot altered in such a way that the level of protection is affected. This shall include damage to cables, excessive numberof connections, terminals not made to original specification, damage to seals, incorrect fitting of glands, etc.Ensure that apparatus is mounted securely.Ensure that seals or sealing materials have not degraded such that they no longer serve the purpose of preventing theingress of flammable atmospheres. Replacement parts shall be in accordance with the manufacturer’s specifications.NOTE: The use of silicon sealant may inhibit the effectiveness of some types of leak detection equipment. Intrinsicallysafe components do not have to be isolated prior to working on them.8. Repair to intrinsically safe componentsDo not apply any permanent inductive or capacitance loads to the circuit without ensuring that this will not exceed thepermissible voltage and current permitted for the equipment in use. Intrinsically safe components are the only typesthat can be worked on while live in the presence of a flammable atmosphere. The test apparatus shall be at the correctrating. Replace components only with parts specified by the manufacturer. Other parts may result in the ignition ofrefrigerant in the atmosphere from a leak.GB/ 19
