- WARNING: The appliance shall be stored in a well-ventilated area where the room size corresponds to the room area as specied.

- WARNING: The appliance shall be stored in a room without continuously operating open ames (e.g.an

operating gas appliance) and ignition sources (e.g. an operating electric heater).

Qualication of Workers

- Specic information about the required qualication 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 ammable gas or vapor being present while the work is being performed.

- Work in conned 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.

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 re extinguishing equipment shall be available to hand. Have a dry powder or CO

re extinguisher adjacent to the charging area.

No Ignition Sources

- All possible ignition sources, including cigarette smoking, should be kept sufciently 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 ammable 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 t for the purpose and to the correct specication. 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.

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 specication, damage to seals, incorrect tting 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 ammable atmospheres. Replacement parts shall be in accordance with the manufacturer’s specications.

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 ammable atmosphere.

- Replace components only with parts specied 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 “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 purging refrigerant systems.

- 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.

- 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 overll the refrigeration system.

- Prior to recharging the system, it shall be pressure-tested with the appropriate purging gas. The system shall be leak- tested 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 re-use of reclaimed refrigerant.

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

- Become familiar with the equipment and its operation.

- Isolate system electrically.

- 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.

- Pump down refrigerant system, if possible.

- If a vacuum is not possible, make a manifold so that refrigerant can be removed from various parts of the system.

- Make sure that cylinder is situated on the scales before recovery takes place.

- Start the recovery machine and operate in accordance with manufacturer's instructions.

- Do not overll cylinders. (No more than 80% volume liquid charge).

- Do not exceed the maximum working pressure of the cylinder, even temporarily.

- 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.

- 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.

- Ensure that there are labels on the equipment stating the equipment contains ammable refrigerant.

Recovery

- 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. 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.

- 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.

- 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 ammable 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.

- WARNING: The appliance shall be stored in a well-ventilated area where the room size corresponds to the room

area as specied.

- WARNING: The appliance shall be stored in a room without continuously operating open ames (e.g.an operating

gas appliance) and ignition sources (e.g.an operating electric heater).

Qualication of Workers

- Specic information about the required qualication 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 ammable gas or vapor

being present while the work is being performed.

- Work in conned 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.

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 re extinguishing equipment shall be available to hand. Have a dry

powder or CO

re extinguisher adjacent to the charging area.

No Ignition Sources

- All possible ignition sources, including cigarette smoking, should be kept sufciently 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 ammable 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 disperseany released refrigerant and preferably expel it externally into the atmosphere.

Checks to the Refrigeration Equipment

- Where electrical components are being changed, they shall be t for the purpose and to the correct specication.

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.

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 specication, damage to seals, incorrect tting 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 ammable atmospheres. Replacement parts shall be in accordance with the manufacturer’s specications.

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 ammable

atmosphere.

- Replace components only with parts specied 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 “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 purging refrigerant systems.

- 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.

- 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 overll the refrigeration system.

- Prior to recharging the system, it shall be pressure-tested with the appropriate purging gas. The system shall be

leak-tested 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

re-use of reclaimed refrigerant.

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

- Become familiar with the equipment and its operation.

- Isolate system electrically.

- 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.

- Pump down refrigerant system, if possible.

- If a vacuum is not possible, make a manifold so that refrigerant can be removed from various parts of the system.

- Make sure that cylinder is situated on the scales before recovery takes place.

- Start the recovery machine and operate in accordance with manufacturer's instructions.

- Do not overll cylinders. (No more than 80% volume liquid charge).

- Do not exceed the maximum working pressure of the cylinder, even temporarily.

- 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.

- 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.

- Ensure that there are labels on the equipment stating the equipment contains ammable refrigerant.

Recovery

- 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. 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.

- 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.

- 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 ammable 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.

Drain Piping

(a) Drain piping should always be in a down hill grade (1/50-1/100) and avoid riding across an elevation or making

traps.

(b) When connecting the drain pipe to unit pay suffcient attention not to apply excess force to the piping on the unit side. Also x the piping at a point as close as possible to the unit. (c) For unit without water pump, please refer to the digram and select drain pipe size according to drain opening inner diameter size. The drain pipe shall be slant downwards (greater than 1/100). The horizontal length of the drain pipe shall be less than 20 m. In case of long pipe, supports shall be provided every 1.5-2m to prevent wavy form. Central piping shall be laid out according to the right gure. Take care not to apply external force onto the drain pipe connection part. (d) For unit with water pump drain pipeuse hard PVC general purpose pipe VP which can be purchased locally. When connecting, insert a PVC pipe end securely into the drain socket before tightening securely using the attached drain hose and clamp. Adhesive must not be used for connection of the drain socket and drain hose (accessory). (e) When constructing drain piping for several units, position the common pipe about 100 mm below the drain outlet of each unit as shown in the sketch Use VP-30(11/4") or thicker pipe for this purpose

(f) The hard PVC pipe put indoor side should be heat insulated. Do not ever provide an air vent. (g) The height of the drain head can be elevated up to a point 500 mm above the ceiling, and when an obstacle exists in the ceiling space, elevate the piping to avoid the obstacle using an elbow or corresponding gadget. When doing this, if the stretch for the needed height is higher than 500mm, the back-ow quantity of drain at the event of interruption of the operation gets too much and it may cause overow at the drain pan. Therefore, make the height of the drain pipe within the distance given in the sketch below. (h) Avoid positioning the drain piping outlet at a place where generation of odor may be stimulated. Do not lead the drain piping direct into a sewer from where sulfur gas may generate.
