of a ﬂammable 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 conﬁned spaces shall be avoided.

The area around the workspace shall be sectioned o. Ensure that the conditions

within the area have been made safe by control of ﬂammable material.

4) Checking for presence of refrigerant

The area shall be checked with an appropriate refrigerating detector prior to and

during work, to ensure the technician is aware of potentially ﬂammable

atmospheres. Ensure that the leak detection equipment being used is suitable

for use with ﬂammable refrigerants, i.e. non-sparking, adequately sealed or

intrinsically safe.

5) 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 CO

ﬁre extinguisher adjacent to the charging area.

6) No ignition sources

No person carrying out work in relation to a refrigerating system which involves

exposing any pipe work that contains or has contained ﬂammable refrigerant

shall use any sources of ignition in such a manner that it may lead to the risk of

ﬁre or explosion. All possible ignition sources, including cigarette smoking,

should be kept suciently far away from the site of installation, repairing,

removing and disposal, during which ﬂammable 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 ﬂammable

hazards or ignition risks. No Smoking signs shall be displayed.

6. Information on servicing

The storage of the appliance should be in accordance with the applicable

regulations or instructions, whichever is more stringent.

7. Sealed electrical components shall be replaced.

8. Intrinsically safe components must be replaced.

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 refrigerating equipment

Where electrical components are being changed, they shall be ﬁt for the purpose

and to the correct speciﬁcations. 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 ﬂammable refrigerants: the actual refrigerant charge 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; and refrigerating 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, 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.

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.

9. Cabling

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

detector using a naked ﬂame) shall not be used.

The following leak detection methods are deemed acceptable for systems

containing ﬂammable refrigerants. Electronic leak detectors shall be used to

detect ﬂammable 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

10. Detection of ﬂammable refrigerants

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.

and the appropriate percentage of gas (25 % maximum) is conﬁrmed. Leak

detection ﬂuids 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

ﬂames 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 o valves) in a part of the system remote from the

leak. Removal of refrigerant shall be according to Removal and evacuation.

When breaking into the refrigerant circuit to make repairs—or for any other

purpose - conventional procedures shall be used. However, for ﬂammable

refrigerants it is important that best practice be followed, since ﬂammability is

a consideration. The following procedure shall be adhered to:

-Safely remove refrigerant following local and national regulations;

-Evacuate;

-Purge the circuit with inert gas (optional for A2L);

-Evacuate (optional for A2L);

-continuously ﬂush or purge with inert gas when using ﬂame to open circuit; and

-open the circuit.

The refrigerant charge shall be recovered into the correct recovery cylinders if

venting is not allowed by local and national codes. For appliances containing

ﬂammable refrigerants, the system shall be purged with oxygen-free nitrogen to

render the appliance safe for ﬂammable refrigerants. This process might need to

be repeated several times.compressed air or oxygen shall not be used for

purging refrigerant systems.

For appliances containing ﬂammable refrigerants, refrigerants purging shall be

achieved by breaking the vacuum in the system with oxygen-free nitrogen and

continuing to ﬁll until the working pressure is achieved, then venting to

atmosphere, and ﬁnally pulling down to a vacuum (optional for A2L).

This process shall be repeated until no refrigerant is within the system (optional

for A2L). When the ﬁnal oxygen-free nitrogen charge is used. the system shall be

vented down to atmospheric pressure to enable work to take place. The outlet

for the vacuum pump shall not be close to any potential ignition sources, and

ventilation shall be available.

11. Removal and evacuation

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 minimise the amount of refrigerant

contained in them.

Cylinders shall be kept in an appropriate position according to the instructions.

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 OFN. 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.

12. Charging procedures

13. Decommissioning

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.

g) Start the recovery machine and operate in accordance with manufacturer's

instructions.

h) Do not overﬁll 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 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 o.

k) Recovered refrigerant shall not be charged into another refrigeration system

unless it has been cleaned and checked.

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 ﬂammable refrigerant.

14. Labelling

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 is 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. 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

the ﬂammable refrigerant. If in doubt, the manufacturer should be consulted. 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.

The recovered refrigerant shall be processed according to local legislation 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 compressor body shall not be heated by an open ﬂame or other

ignition sources to accelerate this process. When oil is drained from a system, it

shall be carried out safely.

ADDITIONAL THINGS YOU SHOULD KNOW

DISPLAYS:

TIMER: AUTO START/STOP FEATURE:

Now that you have mastered the operating

procedure, here are more features in your

control that you should become familiar with.

Use this function only when cooling is not

desired,such as for room air circulation or to

exhaust stale air (on some models). (Remember

to open the vent during this function, but keep

it closed during cooling for maximum cooling

efficiency.) You can choose any fan speed you

prefer.

During this function, the display will show the

actual room temperature, not the set

temperature as in the cooling mode.

In Fan only mode ,the temperature is not

adjusted.

To operate on Dry mode:

In this mode, the air conditioner will generally

operate in the form of a dehumidifier. Since the

conditioned space is a closed or sealed area,

some degree of cooling will continue. On Dry

mode,the fan speed is controlled at Low

automatically.

Press Timer button, the TIMER ON or TIMER OFF

indicator light illuminates. It indicates the Auto

Start or Auto Stop program is initiated. For some

units, keep pressing the Timer button will cancel

the timer settings.

The Cool circuit has an automatic 3 minutes

time delayed start if the unit is turned off

and on quickly.

This prevents overheating of the compressor

and possible circuit breaker tripping.The fan

will continue to run during this time.

The control is capable of displaying

tempera-ture in degrees Fahrenheit or

degrees Celsius.

To convert from one to the other, press and

hold the Up and Down buttons at the same

time for 3 seconds.

Press or hold the UP or DOWN button to change

the Auto time by 0.5 hour increments, up to 10

hours,then at 1 hour increments up to 24 hours.

The control will count down the time remaining

until start.

The selected time will register in 5 seconds, and

the system will automatically revert back to

display the previous temperature setting or room

temperature when the unit is on.(when the unit

is off,there is no display.)

Turning the unit ON or OFF at any time or a

djusting the timer setting to 0.0 will cancel the

Auto Start/Stop timed program.

To operate on Fan Only:

Shows the set temperature in ” °C" or ” °F" and

the Auto-timer settings.While on Fan only mode,

it shows the room temperature. If the room

temperature is too high or low, it will display

" HI" or " LO".

Error codes:

AS - Room temperature sensor error

ES -Evaporator temperature sensor error

HS -Electric heating sensor error(on some

models);

CS -Condenser temperature sensor error

(on some models);

OS -Outside temperature sensor error
