SPECIALIST’S MANUAL

• 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 in- stalled;
  • 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 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.

• Repair and maintenance to electrical compo-nents shall include initial safety checks and com- ponent inspection procedures. If a fault exists that could compromise 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:

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

• Checking for presence of refrigerant
  The area shall be checked with an appropriate refrigerant detector prior to and during work, to ensure the technician is aware of potentially toxic or flammable atmospheres. Ensure that the leak detection equipment being used is suitable for use with all applicable refrigerants, i.e. non-sparking, adequately sealed or intrinsically safe.

• Presence of fire extinguisher
  If 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.

• Ventilated area
  Ensure that the area is in the open or that it is ad- equately ventilated before breaking into the system or conducting any hot work. A degree of ventilation shall continue during the period that the work is carri- ed out. The ventilation should safely disperse any re- leased refrigerant and preferably expel it externally into the atmosphere.

• Checks to the refrigeration equipment
  Where electrical components are being changed, they shall be fit for the purpose and to the correct specification. At all times the manufacturer’s main- tenance and service guidelines shall be followed. If in doubt, consult the manufacturer’s technical depart- ment for assistance.

• Checks to electrical devices

  • that capacitors are discharged: this shall be done in a safe manner to avoid possibility of sparking;
  • that no live electrical components and wiring are exposed while charging, recovering or purging the system.

• Repairs to sealed components
  During repairs to sealed components, all electrical supplies shall be disconnected from the equipment being worked upon prior to any removal of sealed covers, etc. If it is absolutely necessary to have an electrical supply to equipment during servicing, then a permanently operating form of leak detection shall be located at the most critical point to warn of a potentially hazardous situation.
  Particular attention shall be paid to the following to ensure that by working on electrical components, the casing is not altered in such a way that the level of protection is affected. This shall include damage to cables, excessive number of connections, terminals not made to original specification, damage to seals, incorrect fitting of glands, etc.

  • Ensure that the apparatus is mounted securely.
  • Ensure that seals or sealing materials have not de- graded to the point that they no longer serve the purpose of preventing the ingress of flammable atmospheres. Replacement parts shall be in accordance with the manufacturer’s specifications.
    NOTE: The use of silicon sealant can inhibit the effectiveness of some types of leak detection equipment. Intrinsically safe components do not have to be isolated prior to working on them.

• Repair to intrinsically safe components
  Do not apply any permanent inductive or capaci-tance loads to the circuit without ensuring that this will not exceed the permissible voltage and current permitted for the equipment in use.
  Intrinsically safe components are the only types that can be worked on while live in the presence of a fl- ammable atmosphere. The test apparatus shall be at the correct rating.
  Replace components only with parts specified by the manufacturer. Other parts may result in the ignition of refrigerant in the atmosphere from a leak.

• Cabling
  Check that cabling will not be subject to wear, cor- rosion, excessive pressure, vibration, sharp edges or any other adverse environmental effects. The check shall also take into account the effects of aging or continual vibration from sources such as compressors or fans.

• Detection of flammable refrigerants
  Under no circumstances shall potential sources of ignition be used in the searching for or detection of refrigerant leaks. A halide torch (or any other detec- tor using a naked flame) shall not be used.

• Leak detection methods
  Leak detection fluids are suitable for use with most refrigerants but the use of detergents containing ch- lorine shall be avoided as the chlorine may react with the refrigerant and corrode the copper pipe-work.

• Decommissioning
  Before carrying out this procedure, it is essential that the technician is completely familiar with the equip- ment and all its detail. It is recommended good practice that all refrigerants are recovered safely. Prior to the task being carried out, an oil and refri- gerant sample shall be taken in case analysis is required prior to re-use of reclaimed refrigerant. It is essential that electrical power is available before the task is commenced.

  1. Become familiar with the equipment and its operation.
  2. Isolate system electrically.
  3. Before attempting the procedure, ensure that:
  • mechanical handling equipment is available, if required, for handling refrigerant cylinders;
  • all personal protective equipment is available and being used correctly;
  • the recovery process is supervised at all times by a competent person;
  • recovery equipment and cylinders conform to the appropriate standards.
  4. Pump down refrigerant system, if possible.
  5. If a vacuum is not possible, make a manifold so that refrigerant can be removed from various parts of the system.
  6. Make sure that cylinder is situated on the scales before recovery takes place.
  7. Start the recovery machine and operate in accordance with manufacturer’s instructions.
  8. Do not overfill cylinders. (No more than 80% volume liquid charge).
  9. Do not exceed the maximum working pressure of the cylinder, even temporarily.
  10. When the cylinders have been filled correctly and the process completed, make sure that the cylinders and the equipment are removed from site promptly and all isolation valves on the equipment are closed off.
  11. Recovered refrigerant shall not be charged into another refrigeration system unless it has been cleaned and checked.

• Labelling
  Equipment shall be labelled stating that it has been de-commissioned and emptied of refrigerant. The label shall be dated and signed. For appliances containing flammable refrigerants, ensure that there are la- bels on the equipment stating the equipment contains flammable refrigerant.

• Recovery
  When removing refrigerant from a system, either for servicing or decommissioning, it is recommended good practice that all refrigerants are removed safely.

When transferring refrigerant into cylinders, ensure that only appropriate refrigerant recovery cylinders are employed. Ensure that the correct number of cy lenders for holding the total system charge are available. All cylinders to be used are designated for the recovered refrigerant and labelled for that refrigerant (i.e. special cylinders for the recovery of refrigerant). Cylinders shall be complete with pressure-relief valve and associated shut-off valves in good working order. Empty recovery cylinders are evacuated and, if possible, cooled before recovery occurs.

The recovery equipment shall be in good working order with a set of instructions concerning the equipment that is at hand and shall be suitable for the recovery of all appropriate refrigerants including, when applicable, flammable refrigerants. In addition, a set of calibrated weighing scales shall be available and in good working order. Hoses shall be complete with leak-free disconnect couplings and in good condition. Before using the recovery machine, check that it is in satisfactory working order, has been properly maintained and that any associated electrical components are sealed to prevent ignition in the event of a refrigerant release. Consult manufacturer if in doubt.

The recovered refrigerant shall be returned to the refrigerant supplier in the correct recovery cylinder, and the relevant waste transfer note arranged. Do not mix refrigerants in recovery units and especially not in cylinders.

If compressors or compressor oils are to be removed, ensure that they have been evacuated to an acceptable level to make certain that flammable refrigerant does not remain within the lubricant. The evacuation process shall be carried out prior to returning the compressor to the suppliers. Only electric heating to the compressor body shall be employed to accelerate this process. When oil is drained from a system, it shall be carried out safely.
