Cautions

- The installation of pipe-work shall be kept to a minimum.

- Pipe-work shall be protected from physical damage and shall not be installed in an unventilated space, if that space is
smaller than Amin(2m2).

- Compliance with national gas regulations shall be observed.

- Mechanical connections shall be accessible for maintenance purposes.

- The minimum floor area of the room: 2 m2.

- The maximum refrigerant charge amount: 1.7 kg.

- Information for handling, installation, cleaning, servicing and disposal of refrigerant.

- Warning: Keep any required ventilation openings clear of obstruction.

- Notice: Servicing shall be performed only as recommended by the manufacturer.

Unventilated areas

- Warning: The appliance shall be stored in a well-ventilated area where the room size corresponds to the room area as
specified.

- Warning: The appliance shall be stored in a room without continuously operating open flames (e.g. an operating gas
appliance) and ignition sources (e.g. an operating electric heater).

Qualification of workers

- Specific information about the required qualification of the working personnel for maintenance, service and repair
operations.

- Warning: Every working procedure that affects safety means shall only be carried out by competent persons.
Examples for such working procedures are:

- breaking into the refrigerating circuit.

- opening of sealed components

- opening of ventilated enclosures.

Information on servicing

- Prior to beginning work on systems, safety checks are necessary to ensure that the risk of ignition is minimized.

- Work shall be undertaken under a controlled procedure so as to minimized the risk of flammable gas or vapor being
present while the work is being performed.

- 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 material.

Checking for presence of refrigerant

- The area shall be checked with an appropriate refrigerant detector prior to and during work. The leak detection equipment
should be 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, appropriate fire extinguishing equipment shall be available to hand. Have a dry powder
or CO2 fire extinguisher adjacent to the charging area.

No ignition sources

- All possible ignition sources, including cigarette smoking, should be kept sufficiently far away from the site of installation,
repairing, removing and disposal. 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.

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.

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 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

- 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.

5

Cautions

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 no live electrical components and wiring are exposed while charging, recovering or purging the system;

• that there is continuity of earth bonding.

Repairs to sealed components

- During repairs to sealed components, all electrical supplies shall be disconnected 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.

- Ensure that by working on electrical components, the casing is not altered in such a way that the level of protection is
affected, including 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 degraded 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.

Repair to intrinsically safe components

- Do not apply any permanent inductive or 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 types that can be worked on while live in the presence of a flammable
atmosphere.

- 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, 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.

Detection of flammable refrigerants
Removal and evacuation

- The refrigerant charge shall be recovered into the correct recovery cylinders and the system shall be “flushed” 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 purging refrigerant systems.

- Flushing shall be achieved by breaking the vacuum in the system with OFN and continuing to fill until the working
pressure is achieved, then venting to atmosphere, and finally pulling down to a vacuum. This process shall be repeated
until no refrigerant is within the system. When the final OFN charge is used, the system shall be vented down to
atmospheric pressure to enable work to take place.

- The vacuum pump is not close to any ignition sources and that ventilation is available.

Charging procedures

- Ensure that contamination of different refrigerants does not occur when using charging equipment. Hoses or lines
shall be as short as possible to minimise the amount of refrigerant contained in them.

- Cylinders shall be kept upright.

- Ensure that the refrigeration system is earthed prior to charging the system with refrigerant.

- Label the system when charging is complete (if not already).

- Extreme care shall be taken not to overfill the refrigeration system.

- Prior to recharging the system, it shall be pressure-tested with the appropriate purging gas. The system shall be leak­tested on completion of charging but prior to commissioning. A follow up leak test shall be carried out prior to leaving the
site.

Decommissioning

- Before carrying out this procedure, it is essential that the technician is completely familiar with the equipment and all
its detail.

- Prior to the task being carried out, an oil and refrigerant sample shall be taken in case analysis is required prior to re­use of reclaimed refrigerant.

- Electrical power must be available before the task is commenced.
