6.1 Safety Precautions707

WARNING

• All field piping must be completed by a

licensed technician and must comply
with the local and national regulations.

•

When the air conditioner is installed in a
small room, measures must be taken to
prevent the refrigerant concentration in
the room from exceeding the safety limit
in the event of refrigerant leakage. If the
refrigerant leaks and its concentration
exceeds its proper limit, hazards due to
lack of oxygen may result.

• When installing the refrigeration system,

ensure that air, dust, moisture or foreign
substances do not enter the refrigerant
circuit. Contamination in the system may
cause poor operating capacity, high
pressure in the refrigeration cycle,
explosion or injury.

Ventilate the area immediately if there is

•

refrigerant leakage during the
installation. Leaked refrigerant gas is
both toxic and flammable. Ensure there
is no refrigerant leakage after
completing the installation work.

CAUTION

DO NOT deform pipe while cutting. Be

extra careful not to damage, dent, or
deform the pipe while cutting. This will
drastically reduce the heating efficiency
of the unit.

1. Make sure that the pipe is cut at a perfect

Step 2: Remove burrs.

Burrs can affect the air-tight seal of
refrigerant piping connection. They must be
completely removed.

1. Hold the pipe at a downward angle to

CAUTION

• The branching pipe must be installed

horizontally. An angle of more than 10°
may cause malfunction.

• DO NOT install the connecting pipe

until both indoor and outdoor units have
been installed.

• Insulate both the gas and liquid piping to

prevent water leakage.

Step1: Cut pipes

When preparing refrigerant pipes, take extra
care to cut and flare them properly. This will
ensure efficient operation and minimize the
need for future maintenance.

1. Measure the distance between the
indoor and outdoor units.

2. Using a pipe cutter, cut the pipe a little
longer than the measured distance.

Point down

Fig. 6.2

Step 3: Flare pipe ends

NOTE
For R32 refrigerant models, the pipe connection
points must be placed outside of room.

Proper flaring is essential to achieve an
airtight seal.

After removing burrs from cut pipe, seal

1.
the ends with PVC tape to prevent

foreign materials from entering the pipe.
Sheath the pipe with insulating material.

2.
Place flare nuts on both ends of pipe.

3.
Make sure they are facing in the right

direction, because you can’t put them
on or change their direction after flaring.

11.6 NO IGNITION SOURCES

No person carrying out work in relation to a refrigeration 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
sufficiently far away from the site of installation, repairing, removing and disposal, during which flammable
refrigerant can possibly be released to the surroungding 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.

11.7 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.

11.8 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

refrigerant; marking to the equipment continues to be visible and legible.
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.

11.9 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.

11.10 REPAIRS TO SEALED COMPONENTS

11.1 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.

11.2 Particular attention shall be paid to the following to ensure that by working on electrical components, the

CAUTION

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 specification, damage to seals,
incorrect fitting 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 flammable atmospheres. Replacement parts shall be in accordance with the
manufacturer s specifications.
NOTE: The use of silicon sealant may inhibit the effectiveness of some types of leak detection equipment.
Instrinsically safe components do not have to be isolated prior to working on them.

11.11 REPAI 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. Intrinscially safe components are
the only types that can be worked on while live in the presence of a flammable atmosphere. The test apparatus
shall be at the correct rating. Replace components only with parts specified by the manufacturer. Other parts may
result in the ignition of refrigerant in the atmosphere from a leak.

GB-25

11. INFORMATION SERVICING

11.12 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.

11.13 DETECTION OF FLAMMABLE REFRIGERANTS

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.

11.14 LEAK DETECTION METHODS

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. 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 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 or
extinguished. If a leakage of refrigernat 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.

GB

11.15 REMOVAL AND EVACUATION

When breaking into the refrigerant circuit to make repairs of for any other purpose conventional procedures shall
be used, However, it is important that best practice is followed since flammability 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.

The refrigerant charge shall be recovered into the correct recovery cylinders. 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 this task.

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. 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.

GB-26

11. INFORMATION SERVICING

11.16 CHARGING PROCEDURES

In addition to conventional charging procedures, the following requirements shall be followed:
Ensure that contamination of different refrigerants does not occur when using charging equipment. Hoses or

When tranferring refrigerant into cylinders, ensure that only appropriate refrigerant recovery cylinders are
employed. 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-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 flammable 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 recovery cylinder, and the
relevant Waste Transfer Note arranged. Do not mix refrigerants in recovery units and especially not in cylinders.

CAUTION

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 evacuation process
shall be carried out prior to retruning 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.
