REFRIGERANT PIPING

Allowable Piping Length

If the pipe is too long, both the capacity and reliability of the unit will drop. As the number of bends increases, resistance to
the flow of refrigerant system increases, thus lowering cooling capacity. As a result, the compressor may become defective.
Always choose the shortest path and follow the recommendations as tabulated below:

REFRIGERANT PIPING

Piping Works And Flaring Technique

Do not use contaminated or damaged copper tubing. If

•
any piping, evaporator or condenser had been exposed or
had been opened for 15 seconds or more, the system must
be vacuumed. Generally do not remove plastic, rubber
plugs and brass nuts from the valves, fittings, tubing and
coils until it is ready to connect suction or liquid line into
valves or fittings.

If any brazing work is required, ensure that nitrogen gas

•
is passed through coil and joints while the brazing work
is being done. This will eliminate soot formation on the
inside wall of copper tubings.

Cut the pipe stages by stages, advancing the blade of pipe

•
cutter slowly. Extra force and a deep cut will cause more
distortion of pipe and therefore extra burr. See Figure I.

Remove burrs from cut edges of the pipes with remover. See

•
Figure II. Hold the pipe on top position and burr remover
at lower position to prevent metal chips from entering the
pipe. This will avoid unevenness on the flare faces which
will cause gas leak.

Insert the flare nuts, mounted on the connection parts

•
of both the indoor unit and outdoor unit, into the copper
pipes.

The exact length of pipe protruding from the top surface

•
of the swaging block is determined by the flaring tool.
See Figure III.

Fix the pipe firmly on the swaging block. Match the centers

•
of both the swaging block and the flaring punch, then
tighten the flaring punch fully.

The refrigerant pipe connection are insulated by closed

•
cell polyurethane.

Piping Connection To The Units

Align the center of the piping and tighten the flare nut

•
sufficiently with fingers. See Figure IV.

Finally, tighten the flare nut with torque wrench until the

•
wrench clicks.

When tightening the flare nut with the torque wrench,

•
ensure that the tightening direction follows the arrow
indicated on the wrench.

The refrigerant pipe connection are insulated by closed

•
cell polyurethane.

–

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.

1-13

Initial safety checks shall include:

•

that capacitors are discharged, this shall be done in a safe manner to avoid possibility of sparking

–

there shall be no live electrical components and wiring are exposed while charging, recovering or purging the system;

–

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.
Replace components only with parts specified by the manufacturer.

•

Leak detection methods

Ensure that the detector is not a potential source of ignition (for example a halide torch) and is suitable for the refrigerant
used. Leak detection equipment shall be set at a percentage of the LFL of the refrigerant (for R32, LFL is 13%) 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/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 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 close to any ignition sources and there is ventilation available.

Labelling

•

This unit shall be labelled ‘de-commissioned and emptied of refrigerant’. This label shall be dated and signed. Ensure that
there are labels on the equipment stating the equipment contains flammable refrigerant.

1-14

VACUUMING AND CHARGING

Vacuuming is necessary to eliminate all moisture and air from the system.

Vacuuming The Piping And The Indoor Unit

Except for the outdoor unit which is pre-charged with
refrigerant, the indoor unit and the refrigerant connection
pipes must be air-purged because the air containing moisture
that remains in the refrigerant cycle may cause malfunction
of the compressor.

Remove the caps from the valve and the service port.

•
Connect the center of the charging gauge to the vacuum

•

Connect the charging gauge to the service port of the 3-way

•
valve.
Start the vacuum pump. Evacuate for approximately 30

•
minutes. The evacuation time varies with different vacuum
pump capacity. Confirm that the charging gauge needle has

moved towards -760mmHg.

Caution

If the gauge needle does not move to -760mmHg, be sure

•
to check for leakage at flare type connection of the indoor
and outdoor unit and repair the leak before proceeding to
the next step.

ADDITIONAL CHARGE

The refrigerant is pre-charged in the outdoor unit. If the piping length is less than 7.5m, then additional charge after vacuuming
is not necessary. If the piping length is more than 7.5m, then use the additional charge value as indicated in the table.

Additional refrigerant charge [g] per additional 1m length as tabulated

Eliminazione Acqua Di Condensa Dell’Unità Esterna
(Solo Per Le Versioni In Pompa Di Calore)

Ci sono 2 fori alla base dell’unità esterna per garantire

•
la fuoriuscita dell’acqua. Inserire il raccordo a gomito in
uno del 2 fori.
Per installare il raccordo a gomito, effettuare le seguenti

•
operazioni: prima inserire una parte del raccordo all’interno
del foro (Parte A). Quindi tirare che tra la tubazione e la
base dell’unità ci sia una fondare saldamente. Assicorarsi
che tra la tubazione e la base dell’unità ci sia una perfetta
aderenza.
Se l’unità esterna è installata in amblenti rolto freddi,

•
l’acqua di condensa potrebbe gecare du’interno della base.
Per evitario, rimuovere il tappo presente nella base per
