Special Precautions for R407
Special Precautions When Dealing With Refrigerant R407C Unit
1) What is new refrigerant R407C?
R407C is a zeotropic refrigerant mixture which has Zero Ozone Depletion Potential (ODP = 0) and thus
conformed to the Montreal Protocol regulation. It requires Polyol-ester oil (POE) oil for its compressor's
lubricant. Its refrigerant capacity and performance are about the same as the refrigerant R22.
2) Components
Mixture weight composition R32(23%), R125(25%), R134a(52%)
3) Characteristic
• R407C liquid and vapor components have different compositions when the fluid evaporates or
condenses. Hence, when leak occurs and only vapor leaks out, the composition of the refrigerant
mixture left in the system will change and subsequently affect the system performance. DO NOT add
new refrigerant to leaked system. It is recommended that the system should be evacuated thoroughly
before recharging with R407C.
• When refrigerant R407C is used, the composition will differ depending on whether it is in gaseous or
liquid phase. Hence when charging R407C, ensure that only liquid is being withdrawn from the cylinder
or can. This is to make certain that only original composition of R407C is being charged into the
system.
• POE oil is used as lubricant for R407C compressor, which is different from the mineral oil used for R22
compressor. Extra precaution must be taken not to expose the R407C system too long to moist air.
4) Check list before installation/servicing
• Tubing
Refrigerant R407C is more easily affected by dust of moisture compared with R22, make sure to
temporarily cover the ends of the tubing prior to installation
• Compressor oil
No additional charge of compressor oil is permitted.
• Refrigerant
No other refrigerant other that R407C
• Tools
Tools specifically for R407C only (must not be used for R22 or other refrigerant)
i) Manifold gauge and charging hose
ii) Gas leak detector
iii) Refrigerant cylinder/charging cylinder
iv) Vacuum pump c/w adapter
v) Flare tools
vi) Refrigerant recovery machine
5) Handling and installation guidelines
Like R22 system, the handling and installation of R407C system are closely similar. All precautionary
measures; such as ensuring no moisture, no dirt or chips in the system, clean brazing using nitrogen, and
thorough leak check and vacuuming are equally important requirements. However, due to zeotropic nature
of R407C and its hydroscopic POE oil, additional precautions must be taken to ensure optimum and
trouble-free system operation.
a) Filter-dryer must be installed along the liquid line for all R407C air conditioners. This is to minimise the
contamination of moisture and dirt in the refrigerant system. Filter-dryer must be of molecular sieve
type. For a heat-pump system, install a two-way flow filter dryer along the liquid line.
b) During installation or servicing, avoid prolong exposure of the internal part of the refrigerant system to
moist air. Residual POE oil in the piping and components can absorb moisture from the air.
Page 63
Page 65
c) Ensure that the compressor is not expose to open air for more than the recommended time specified by
its manufacturer (typically less than 10 minutes). Removed the seal-plugs only when the compressor is
about to be brazed.
d) The system should be thoroughly vacuumed to 1.0 Pa (-700mmHg) or lower. This vacuuming level is
more stringent than R22 system so as to ensure no incompressible gas and moisture in the system.
e) When charging R407C, ensure that only liquid is being withdrawn from the cylinder or can. This is to
ensure that only the original composition of R407C is being delivered into the system. The liquid
composition can be different from the vapor composition.
33% / 33% / 34%
23% / 25% / 52%
R32/R125/R134
Composition of R407C in vapour phase
is different from liquid phase.
f) Normally, the R407C cylinder or can is being equipped with a dip-pipe for liquid withdrawal. However, if
the dip-pipe is not available, invert the cylinder or can so as to withdraw liquid from the valve at the
bottom.
Liquid

Invert cylinder
without dip-pipe
Dip-pipe
g) When servicing leak, the top-up method, commonly practiced for R22 system, is not recommended for
R407C system. Unlike R22 where the refrigerant is of a single component, the composition of R407C,
which made-up of three different components, may have changed during the leak. Consequently, a
top-up may not ensure that the R407C in the system is of original composition. This composition shift
may adversely affect the system performance. It is recommended that the system should be evacuated
thoroughly before recharging with R407C.

(2) Installation of Outdoor Unit
As condensing temperature rises, evaporating temperature rises and cooling capacity drops.
In order to achieve maximum cooling capacity, the location selected for outdoor unit should
fulfill the following requirements:
• Install the condensing (outdoor) unit in away such that hot air distributed by the outdoor
condensing unit cannot be drawn in again (as in the case of short circuit of hot discharge
air). Allow sufficient space for maintenance around the unit.
• Ensure that there is no obstruction of air flow into or out of the unit. Remove obstacles
which block air intake or discharge.
• The location must be well ventilated, so that the unit can draw in and distribute plenty of air
thus lowering the condensing temperature.
• A place capable of bearing the weight of the outdoor unit and isolating noise and vibration.
• A place protected from direct sunlight. Otherwise use an awning for protection, if
necessary.
• The location must not be susceptible to dust or oil mist.
Installation Clearance
• Outdoor units must be installed such that there is no short circuit of the hot discharge air or
obstruction to smooth air flow. Select the coolest possible place where intake air should not
be hotter than the outside temperature (max. 45°C)

(3) Refrigerant Piping
Maximum Pipe Length And Maximum Number Of Bends
• When the pipe length becomes too long, both the capacity and reliability drop. As the number of bends
increases, system piping resistance to the refrigerant flow increases, thus lowering the cooling capacity,
and as the result the font compressor may become defective. Always choose the shortest path and follow
the recommendation as tabulated below:

(4) Wiring
Electrical Connections
• Wiring regulations on wire diameters differ from country to country. Please refer to your LOCAL
ELECTRICAL CODES for field wiring rules. Be sure that installation comply with such rules and regulations.
General Precautions
• Ensure that the rated voltage of the unit corresponds to the name plate before carrying out proper wiring
according to the wiring diagram.
• Provide a power outlet to be used exclusively for each unit. A power supply disconnect and a circuit
breaker for over-current protection should be provided in the exclusive line.
• The unit must be GROUNDED to prevent possible hazards due to insulation failures.
• All wiring must be firmly connected.
• All wiring must not touch the hot refrigerant piping, compressor or any moving parts of fan motors.
Page 71
Page 73
(5) Vacuuming and charging
• The precharged outdoor unit does not need any vacuuming or charging. However once it is connected,
the connecting pipe line and the indoor need to be vacuumed before releasing the R22/R407C from the
outdoor unit.
1) Open the service port core cap.
2) Connect pressure gauge to the service port.
3) Connect the line to vacuum pump. Open the charging manifold valve and turn the pump on. Vacuum
to –0.1 MPa (-760mmHg) or lower. (Evacuation time varies by the pump but averagely in 1 hour).
CAUTION FOR R407C
R407C must be charged as liquid. Usually R407C cylinder is equipped with a dip-pipe for liquid withdrawal. If
there is no dip-pipe, the cylinder should be inverted so as to withdraw liquid R407C from the valve.
CAUTION FOR R407C
Do not top-up when servicing leak, as this will reduce the unit performance. Vacuum the unit thoroughly and
then charge the unit with fresh R407C according to the amount recommended in the specification.

Page 81
The design of the MLC outdoor series allows servicing to be carried out readily and easily. The removal of
the top side, front and back panel make almost every part accessible.
Under normal circumstances, these outdoor units only require a check and cleaning of air intake coil surface
once quarterly. However, if a unit is installed in areas subjected to much oil mist and dust, the coils must be
regularly cleaned by qualified Air Conditioner Service Technicians to ensure sufficient heat exchange and
proper operation. Otherwise, the systems life span may be shortened.
CAUTION!
Do not charge OXYGEN, ACETYLENE OR OTHER FLAMMABLE and poisonous gases into the unit
when performing a leakage test or an airtight test. These gases could cause severe explosion and
damage if exposed to high temperature and pressure.
It is recommended that only nitrogen or refrigerant be charged when performing the leakage or airtight
test.
