SERVICE PRECAUTIONS

When servicing a dehumidifier with R290, please observe the following warnings.

Area checks

Before starting work on systems containing flammable refrigerants, safety checks must be carried out to ensure that the risk of ignition is minimised. If the refrigeration system is to be repaired, the following precautions must be taken before any work is carried out on the system.

Procedure

Work must be carried out using a controlled procedure to minimise the risk of flammable gas or vapour being present during the work.

General work area

All maintenance personnel and others working in the local area shall be instructed as to the nature of the work to be carried out. Avoid working in confined spaces. The area around the work area should be cordoned off. Ensure that conditions within the area have been made safe by controlling flammable materials.

Check for presence of refrigerant

Check the area with an appropriate refrigerant detector before and during the work to ensure that the technician is aware of any potentially flammable atmosphere. Ensure that the leak detection equipment used is suitable for use with flammable refrigerants, i.e. non-sparking, adequately sealed or intrinsically safe.

Presence of fire extinguishers

If hot work is to be carried out on the refrigeration unit or any associated parts, suitable fire extinguishing equipment must be available. A dry powder or CO2 fire extinguisher should be kept close to the loading area.

No ignition sources

No person carrying out work on a refrigeration system which involves the exposure of pipework containing or having contained flammable refrigerant shall use any source of ignition in such a way as to create a risk of fire or explosion. All possible ignition sources, including cigarette smoking, shall be kept sufficiently distant from the site of installation, repair, removal and disposal where flammable refrigerant may be released into the surrounding atmosphere. Before starting work, the area around the equipment must be inspected to ensure that there are no flammable or ignition hazards. „No smoking“ signs should be posted.

Ventilated area

Ensure that the area is outdoors or adequately ventilated before entering the system or carrying out hot work. Some ventilation must be maintained while the work is being carried out. The ventilation should safely disperse any released refrigerant, preferably to the outside atmosphere.

Checks on the refrigeration system

When electrical components are changed, they must be fit for purpose and to the correct specification. The manufacturer's maintenance and service instructions must always be followed. If in doubt, the manufacturer's technical department should be consulted.

Presence of fire extinguishers

If hot work is to be carried out on the refrigeration unit or any associated parts, suitable fire extinguishing equipment must be available. A dry powder or CO2 fire extinguisher should be kept close to the loading area.

No ignition sources

No person carrying out work on a refrigeration system which involves the exposure of pipework containing or having contained flammable refrigerant shall use any source of ignition in such a way as to create a risk of fire or explosion. All possible ignition sources, including cigarette smoking, shall be kept sufficiently distant from the site of installation, repair, removal and disposal where flammable refrigerant may be released into the surrounding atmosphere. Before starting work, the area around the equipment must be inspected to ensure that there are no flammable or ignition hazards. „No smoking“ signs should be posted.

Checks on the refrigeration system

When electrical components are changed, they must be fit for purpose and to the correct specification. The manufacturer's maintenance and service instructions must always be followed. If in doubt, the manufacturer's technical department should be consulted.

The following checks must be carried out for systems using flammable refrigerants:

• The size of the charge is appropriate to the size of the room in which the refrigerant-containing parts are installed;
• that the fans and vents are working properly and are not obstructed;
• If an indirect circuit is used, the secondary circuit is checked for the presence of refrigerant;
• Markings on the equipment are still visible and legible. Illegible markings and signs shall be corrected;
• Refrigerant lines or components are installed in a position where they are unlikely to be exposed to substances that could corrode refrigerant-containing components, unless the components are constructed of materials that are inherently resistant to corrosion or are adequately protected against such corrosion.

Inspection of electrical equipment

Repair and maintenance of electrical components shall include initial safety checks and component inspection procedures. If there is a fault which could compromise safety, no electrical supply shall be connected to the circuit until it has been satisfactorily rectified. If the fault cannot be rectified immediately but it is necessary to continue operation, an appropriate temporary solution shall be used. This must be reported to the owner of the equipment so that all parties are advised.

Initial safety checks should include

• that the capacitors are discharged: this must be done in a safe manner to avoid the possibility of sparking;
• that no live electrical components or wiring are exposed during charging, recovery or purging of the system;
• that there is continuity of earth connection.
