1 General safety precautions1.3.2Installation siteWARNINGMake sure there is no oxygen in the system. Refrigerantmay only be charged after performing the leak test and thevacuum drying. Provide sufficient space around the unit for servicing and aircirculation. Make sure the installation site withstands the unit's weight andvibration. Make sure the area is well ventilated. Do NOT block anyventilation openings. Make sure the unit is level.Do NOT install the unit in the following places: In potentially explosive atmospheres. In places where there is machinery that emits electromagneticwaves. Electromagnetic waves may disturb the control system,and cause malfunction of the equipment. In places where there is a risk of fire due to the leakage offlammable gases (example: thinner or gasoline), carbon fibre,ignitable dust. In places where corrosive gas (example: sulphurous acid gas) isproduced. Corrosion of copper pipes or soldered parts may causethe refrigerant to leak.1.3.3 In case re-charge is required, refer to the nameplate of the unit. Itstates the type of refrigerant and necessary amount. The unit is factory charged with refrigerant and depending on pipesizes and pipe lengths some systems require additional chargingof refrigerant. Only use tools exclusively for the refrigerant type used in thesystem, this to ensure pressure resistance and prevent foreignmaterials from entering into the system. Charge the liquid refrigerant as follows:IfA siphon tube is presentThenCharge with the cylinder upright.(i.e., the cylinder is marked with"Liquid filling siphon attached")A siphon tube is NOT presentCharge with the cylinder upsidedown.RefrigerantIf applicable. See the installation manual or installer reference guideof your application for more information.NOTICEMake sure refrigerant piping installation complies withapplicable legislation. In Europe, EN378 is the applicablestandard. Open refrigerant cylinders slowly. Charge the refrigerant in liquid form. Adding it in gas form mayprevent normal operation.NOTICECAUTIONMake sure the field piping and connections are notsubjected to stress.When the refrigerant charging procedure is done or whenpausing, close the valve of the refrigerant tankimmediately. If the valve is not closed immediately,remaining pressure might charge additional refrigerant.Possible consequence: Incorrect refrigerant amount.WARNINGDuring tests, NEVER pressurize the product with apressure higher than the maximum allowable pressure (asindicated on the nameplate of the unit).WARNINGTake sufficient precautions in case of refrigerant leakage. Ifrefrigerant gas leaks, ventilate the area immediately.Possible risks:1.3.4BrineIf applicable. See the installation manual or installer reference guideof your application for more information.WARNING Excessive refrigerant concentrations in a closed roomcan lead to oxygen deficiency.The selection of the brine MUST be in accordance with theapplicable legislation. Toxic gas may be produced if refrigerant gas comesinto contact with fire.WARNINGWARNINGAlways recover the refrigerant. Do NOT release themdirectly into the environment. Use a vacuum pump toevacuate the installation.NOTICEAfter all the piping has been connected, make sure there isno gas leak. Use nitrogen to perform a gas leak detection.NOTICE To avoid compressor breakdown, do NOT charge morethan the specified amount of refrigerant.Take sufficient precautions in case of brine leakage. Ifbrine leaks, ventilate the area immediately and contactyour local dealer.WARNINGThe ambient temperature inside the unit can get muchhigher than that of the room, e.g. 70 C. In case of a brineleak, hot parts inside the unit can create a hazardoussituation.WARNINGThe use and installation of the application MUST complywith the safety and environmental precautions specified inthe applicable legislation.
