• Information on servicing

1. Area checks

Prior to beginning work on systems containing ammable refrigerants,

safety checks are necessary to ensure that the risk of ignition is

minimised. For repair to the refrigerating system, the following

precautions shall be complied with prior to conducting work on the

system.

2. Work procedure

Works shall be undertaken under a controlled procedure so as to

minimise the risk of a ammable gas or vapour being present while the

work is being performed.

3. General work area

All maintenance sta and others working in the local area shall be

instructed on the nature of work being carried out. Work in conned

spaces shall be avoided. The area around the work space shall be

sectioned o. 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. no 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 on hand. Have a dry power or CO2 re extinguisher next to

the charging area.

AF_Manual_AC_12000BTU_BAC4255_BAC4255N.indd 13 21/01/2019 10:24

6. No ignition sources

No person carrying out work with a refrigeration system which involves

exposing any pipe work that contains or has contained ammable

refrigerant shall use any sources of ignition in such a manner that

it may lead to risk of re or explosion. All possible ignition sources,

including cigarette smoking, should be kept suiciently far away from

the site of installation, repairing, removing and disposal, during which

ammable 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 the work 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 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 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

circuits shall be checked for the presence of refrigerant; marking to

the equipment continues to be visible and legible.

AF_Manual_AC_12000BTU_BAC4255_BAC4255N.indd 14 21/01/2019 10:24

15

EN

Portable air conditioner | Aire acondicionado portátil | Ar Condicionado Portátil

• marking 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.

9. 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, and 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.

10. Repairs to sealed components

10.1 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.

AF_Manual_AC_12000BTU_BAC4255_BAC4255N.indd 15 21/01/2019 10:24

16

10.2 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 aected. This shall include

damage to cables, excessive number of connections, terminals not

made to original specication, damage to seals, incorrect tting of

glands, etc.

• Ensure that apparatus is mounted securely.

• Ensure that seals or sealing materials have not degraded in such

a way 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.

Note

: the use of silicon sealant may inhibit the eectiveness of some

types of leak detection equipment. Intrinsically safe components do not

have to be isolated prior to working on them.

11. 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. The test apparatus shall be

at the correct rating.

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.

12. Cabling

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

pressure, vibration, sharp edges or any other adverse environmental

eects. The check shall also take into account the eects of aging or

continual vibration from sources such as compressors or fans.

17

EN

Portable air conditioner | Aire acondicionado portátil | Ar Condicionado Portátil

13. Detection of ammable refrigerants

Under no circumstances shall potential sources of ignition be used

when in the search for or detection of refrigerant leaks. A halide torch

(or any other detector using a naked ame) shall not be used.

14. Leak detection methods

The following leak detection methods are deemed acceptable for

systems containing ammable refrigerants. Electronic leak detectors

shall be used to detect 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.

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 conrmed. Leak

detection uids are suitable for use with most refrigerants but the use

of detergents containing chlorine shall be avoided as the chlorine may

react with the refrigerant and corrode the copper pipe-work.

If a leak is suspected, all naked ames shall be removed or

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 o valves) in a part of the system remote from the leak.

Oxygen free nitrogen (OFN) shall then be purged through the system

both before and during the brazing process.

15. Removal and evacuation

When accessing the refrigerant circuit to make repairs for any

other purpose, conventional procedures shall be used. However,

it is important that best practice is followed since ammability is a

consideration. The following procedure shall be adhered to:

• remove refrigerant;

• purge the circuit with inert gas;

• evacuate;

AF_Manual_AC_12000BTU_BAC4255_BAC4255N.indd 17 21/01/2019 10:24

18

• purge again with inert gas;

• open the circuit by cutting or brazing.

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 it 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 in 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 closed to any

ignition sources and there is ventilation available.

16. Charging procedures

In addition to conventional charging procedures, the following

requirements shall be followed:

• Ensure that contamination of dierent refrigerants does not occur

when using charging equipment. Hoses or lines shall be as short as

possible to minimize 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 OFN.

The system shall be leak tested on completion of charging but prior

AF_Manual_AC_12000BTU_BAC4255_BAC4255N.indd 18 21/01/2019 10:24

19

EN

Portable air conditioner | Aire acondicionado portátil | Ar Condicionado Portátil

to commissioning. A follow up leak test shall be carried out prior to

leaving the site.

17. Decommissioning

Before carrying out this procedure, it is essential that the technician

be 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 cylinder is situated on the scales before recovery

takes place.

AF_Manual_AC_12000BTU_BAC4255_BAC4255N.indd 19 21/01/2019 10:24

20

g) Start the recovery machine and operate in accordance with

manufacturer’s instructions.

h) Do not overll the cylinders (no more than 80 % of the 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 the cylinders and the equipment are removed

from the site promptly and all isolation valves on the equipment are

closed o.

k) Recovered refrigerant shall not be charged into another refrigeration

system unless it has been cleaned and checked.

18. 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.

19. Recovery

• When removing refrigerant from a system, either for service

or decommissioning, it is recommended good practice that all

refrigerants be removed safely.

• When transferring refrigerant into cylinders, ensure that only

appropriate refrigerant recovery cylinders are used. Ensure that the

correct numbers 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-o valves in good working

order.
