Page 72.2 SAFETY PRECAUTIONS ON SERVICINGPlease follow these warnings when to undertake the following when servicing a dehumidifier with R290. 2.2.1 Checks to the area.Prior to beginning work on systems containing flammable refrigerants, safety checks are necessary to ensure that the risk of ignition is minimized. For repair to the refrigerating system, the following precautions shall be complied with prior to conducting work on the system. 2.2.2 Work procedureWork shall be undertaken under a controlled procedure to minimize the risk of flammable gas or vapour being present while the work is being performed. 2.2.3 General work areaAll maintenance staff and others working in the local area shall be instructed on the nature of the work being carried out. Work in confined spaces shall be avoided. The area around the workspace shall be sectioned off. Ensure that the conditions within the area have been made safe by control of flammable materials. 2.2.4 Checking for the presence of refrigerantThe area shall be checked with an appropriate refrigerant detector prior to and during work, ensuring the technician is aware of potentially flammable atmospheres. Ensure that the leak detection equipment being used is suitable for use with flammable refrigerants, i.e. no sparking, adequately sealed or intrinsically safe. 2.2.5 Presence of fire extinguisherIf any hot work is to be conducted on the refrigeration equipment or any associated parts, appropriate fire extinguishing equipment shall be available to hand. Have a dry powder or CO2 fire extinguisher adjacent to the charging area.

Page 82.2.6 No ignition sourcesNo person carrying out work in relation to a refrigeration system which involves exposing any pipe work that contains or has contained flammable refrigerant shall use any sources of ignition in such a manner that it may lead to the risk of fire or explosion. All possible ignition sources, including cigarette smoking, should be kept sufficiently far away from the site of installation, repair, removal and disposal, during which flammable refrigerant can possibly be released into the surrounding space. Prior to work taking place, the area around the equipment is to be surveyed to make sure that there are no flammable hazards or ignition risks. “No Smoking” signs shall be displayed. 2.2.7 Ventilated areaEnsure that the area is in the open or that it is adequately ventilated before breaking into the system or conducting any hot work. A degree of ventilation shall continue during the period that the work is carried out. The ventilation should safely disperse any released refrigerant and preferably expel it externally into the atmosphere. 2.2.8 Checks to the refrigeration equipmentWhere electrical components are being changed, they shall be fit for the purpose and to the correct specification. At all times, the manufacturer’s maintenance and service guidelines shall be followed. If in doubt, consult the manufacturer’s technical 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 the equipment continues to be visible and legible. Markings and signs that are illegible shall be corrected;– Refrigeration pipes or components are installed in a position where they are unlikely to be exposed to any substance which may corrode refrigerant-containing components unless the components are constructed of materials which are inherently resistant to being corroded or are suitably protected against being so corroded.

Page 92.2.9 Checks to electrical devicesRepair and maintenance of electrical components shall include initial safety checks and component inspection procedures. If a fault exists that could compromise the safety, then no electrical supply shall be connected to the circuit until 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 are advised.Initial safety checks shall include:•those capacitors are discharged: this shall be done safely to avoid the possibility of sparking;•that there are no live electrical components and wiring exposed while charging, recovering or purging the system;•that there is a continuity of earth bonding.
