16. Information on servicing:

1) Checks to the area Prior to beginning work on

systems containing ammable 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) Work procedure Work shall be undertaken under

a controlled procedure so as to minimize the risk of a ammable gas or vapor being present while the work is being performed.

3) General work area All maintenance staff and

others working in the local area shall be instructed on the nature of work being carried out. Work in conned 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 ammable material

4) 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 ammable atmospheres. Ensure that the leak detection equipment being used is suitable for use with ammable refrigerants, i.e. non-sparking, adequately sealed or intrinsically safe.

5) Presence of re extinguisher If any hot work is

to be conducted on the refrigeration equipment or any associated parts, appropriate re extinguishing equipment shall be available to hand. Have a dry powder or CO 2 re extinguisher adjacent to the charging area.

6) No ignition sources No person carrying out

work in relation to a refrigeration system which involves exposing any pipe work shall use any sources of ignition in such a manner that it may lead to the risk of re or explosion. All possible ignition sources, including cigarette smoking, should be kept sufciently far away from the site of installation, repairing, removing and disposal, during which refrigerant can possibly be released to the surrounding space. Prior to work taking place, the area around the equipment is to be surveyed to make sure that there are no ammable hazards or ignition risks. No Smoking signs shall be displayed.

7) Ventilated area Ensure 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.

8) Checks to the refrigeration equipment Where

electrical components are being changed, they shall be t for the purpose and to the correct specication. 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 ammable 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 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. Caution: Risk of re Operating instructions Read technical manualACD-18KBTU 15

The following checks shall be applied to installations using ammable 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 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.

Checks to electrical devices Repair and maintenance to electrical components shall include initial safety checks and component 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 there no live electrical components and wiring are exposed while charging, recovering or purging the system; -- That there is continuity of earth bonding.

17. 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.

2) 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 specication, damage to seals, incorrect tting of glands, etc. Ensure that apparatus is mounted securely. Ensure that seals or sealing materials have not degraded such that they no longer serve the purpose of preventing the ingress of ammable atmospheres. Replacement parts shall be in accordance with the manufacturer's specications. NOTE: The use of silicon sealant may inhibit the effectiveness of some types of leak detection equipment. Intrinsically safe components do not have to be isolated prior to working on them.

18. Repair to intrinsically safe components

Do not apply any permanent inductive o

capacitance 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 type

that can be worked on while live in the presence of a ammable atmosphere. The test apparatus shall be at the correct rating. Replace components only with parts specied by the manufacturer. Other parts may result in the ignition of refrigerant in the atmosphere from a leak.

Check that cabling will not be subject to wear, corrosion, 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.

20. Detection of ammable refrigerants

Under no circumstances shall potential sources o

ignition be used in the searching for or detection of refrigerant leaks. A halide torch (or any other detector using a naked ame) shall not be used.

21. Leak detection methods

The following leak detection methods are deemed acceptable for systems containing ammable refrigerants. Electronic leak detectors shall be used to detec

ammable refrigerants, but the sensitivity may not be adequate, or may need re-calibration

(Detection equipment shall be calibrated in a refrigerant-free area). Ensure that the detector is not a potential source of ignition and is suitable for the refrigerant used. Leak detection equipment shall be set at a percentage of the LFL of the refrigerant and shall be calibrated to the refrigerant employed and the appropriate percentage of gas (25 % maximum) is conrmed. Leak detection uids are suitable for use with most refrigerants but the use of detergents containing chlorine shall be avoided as the chlorin

may react with the refrigerant and corrode the copper pipe-work. If a leak is suspected, all naked ames shall be removed/ extinguished. If a leakage of refrigerant is found which requires brazing, all of the refrigerant shall be recovered from the system, or isolated (by means of shut off valves) in a part of the system remote from the leak. Oxygen fre

nitrogen (OFN) shall then be purged through the system both before and during the brazing process.

22. Removal and evacuation

When breaking into the refrigerant circuit to mak

repairs or for any other purpose conventional procedures shall be used. However, it is importan

that best practice is followed since inammability is a consideration. The following procedure shall be adhered to: -- Remove refrigerant; -- Purge the circuit with inert gas; -- Evacuate; -- Purge again with inert gas; -- Open the circuit by cutting or brazing.16 ACD-18KBTU The refrigerant charge shall be recovered into the correct recovery cylinders. The system shall be ushed with OFN to render the unit safe. This process may need to be repeated several times. Compressed air or oxygen shall not be used for this task. Flushing shall be achieved by breaking the vacuum in the system with OFN and continuing to ll until the working pressure is achieved, then venting to atmosphere, and nally pulling down to a vacuum. This process shall be repeated until no refrigerant is within the system. When the nal OFN charge is used, the system shall be vented down to atmospheric pressure to enable work to take place. This operation is absolutely vital if brazing operations on the pipe-work are to take place. Ensure that the outlet for the vacuum pump is not close to any ignition sources and there is ventilation available.

Before carrying out this procedure, it is essential that the technician is completely familiar with the equipment 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 refrigerant 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. a) Become familiar with the equipment and its operation. b) Isolate system electrically. c) 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. d) Pump down refrigerant system, if possible. e) If a vacuum is not possible, make a manifold so that refrigerant can be removed from various parts of the system. f) Make sure that the cylinder is situated on the scales before recovery takes place. g) Start the recovery machine and operate in accordance with manufacturer's instructions. h) Do not overll cylinders. (No more than 80 % volume liquid charge).

i) Do not exceed the maximum working pressure of

the cylinder, even temporarily. j) When the cylinders have been lled 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. k) Recovered refrigerant shall not be charged into another refrigeration system unless it has been cleaned and checked.

Equipment shall be labeled stating that it has been de-commissioned and emptied of refrigerant. The label shall be dated and signed. Ensure that there are labels on the equipment stating the equipment contains ammable refrigerant.

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 cylinders for holding the total system charge are available.
