16. Information on servicing:
 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.
 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.
 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
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, 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.
 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.
 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 sufciently 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.
 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
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.

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.
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.
 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 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
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 specications.
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.
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.
 
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.

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 ame) shall not be used.
 
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 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 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/ 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 free
nitrogen (OFN) shall then be purged through the
system both before and during the brazing process.
Removal and evacuation
When breaking into the refrigerant circuit to make
repairs or for any other purpose conventional
procedures shall be used. However, it is important
that best practice is followed since inammability
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.
 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.
 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 the 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.

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.
Recovery
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. All cylinders to be used are designated
for the recovered refrigerant and labeled 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
including, when applicable, ammable refrigerants.
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. 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. Consult manufacturer if in
doubt.
The recovered refrigerant shall be returned to the
refrigerant supplier in the correct recover 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. When oil is
drained from a system, it shall be carried out safely.

Refrigerant Leak Detector
Appropriate Installation Location
The left picture is the schematic
diagram of a refrigerant leak detector.
Please note that:
The installation site should be well-ventilated.
The sites for installing and maintaining an air
conditioner using Refrigerant R32 should be free
from open re or welding, smoking, drying oven or
any other heat source higher than 548 which easily
produces open re.
When installing an air conditioner, it is necessary to
take appropriate anti-static measures such as wear
anti-static clothing and/or gloves.
It is necessary to choose the site convenient for
installation or maintenance wherein the air inlets
and outlets of the indoor and outdoor units should
be not surrounded by obstacles or close to any
heat source or combustible and/or explosive
environment.
If the indoor unit suffers refrigerant leak during the
installation, it is necessary to immediately turn off
the valve of the outdoor unit and all the personnel
should go out until the refrigerant leaks completely
for 15 minutes. If the product is damaged, it is a
must to carry such damaged product back to the
maintenance station and it is prohibited to weld the
refrigerant pipe or conduct other operations on the
user's site.
It is necessary to choose the place where the inlet
and outlet air of the indoor unit is even.
 It is necessary to avoid the places where there
are other electrical products, power switch plugs
and sockets, kitchen cabinet, bed, sofa and other
valuables right under the lines on two sides of the
indoor unit.
