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.NOTICEMake sure the field piping and connections are NOTsubjected to stress.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:▪ Excessive refrigerant concentrations in a closed roomcan lead to oxygen deficiency.▪ Toxic gas may be produced if refrigerant gas comesinto contact with fire.DANGER: RISK OF EXPLOSIONPump down – Refrigerant leakage. If you want to pumpdown the system, and there is a leak in the refrigerantcircuit:▪ Do NOT use the unit's automatic pump down function,with which you can collect all refrigerant from thesystem into the outdoor unit. Possible consequence:Self-combustion and explosion of the compressorbecause of air going into the operating compressor.▪ Use a separate recovery system so that the unit'scompressor does NOT have to operate.WARNINGALWAYS 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.▪ When the refrigerant system is to be opened,refrigerant MUST be treated according to the applicablelegislation.WARNINGMake sure there is no oxygen in the system. Refrigerantmay only be charged after performing the leak test and thevacuum drying.▪ In case recharge is required, see 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.
