Unit piping
The refrigerant piping can be routed to the unit in a
number of ways (left or right from the back of the unit), by
using the cut-out holes on the casing of the unit (see figure).
Bend the pipes carefully to the required position in order to
aligned it with the holes. For the right hand and rear side
out, hold the bottom of the piping and then position it to the
required direction (see figure). The condensation drain hose
can be taped to the pipes.
Mount The Unit Onto The Installation Plate
Hook the indoor unit onto the upper portion of the
installation plate (Engage the two hooks at the rear top of
the indoor unit with the upper edge of the installation plate).
Ensure that the hooks are properly seated on the
installation plate by moving it to the left and right.
Right & Rear Side Routing
1. Hook the unit onto the installation plate.
2. A unit support plate on the
installation plate can be used to
hold the unit slanted (See figures)
to ease the piping installation
work.
3. Fix the screw underneath
after completion of
installation.
Piping Length & Elevation
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, and as a result the compressor may become
defective. Always choose the shortest path and follow the recommendations as tabulated on next page :
Remark: The refrigerant that has been pre-charged in the outdoor unit is for piping length up to 5 m.

Piping Connection To The Units
Align the center of the piping and tighten the flare nut
sufficiently with fingers.
Finally, tighten the flare nut with the torque wrench
until the wrench clicks.
If any brazing work is required, ensure that the nitrogen
gas is passed through coil and joints while the brazing
work is being done. This will eliminate soot formation
on the inside walls of the copper tubings.
Cut the connection pipe with a pipe cutter.
Remove burrs from cut edges of the pipes with remover.
Hold the end of the pipe downwards to prevent metal
chips from entering the pipe.
Insert the flare nuts, mounted on the connection parts of
both the indoor unit and outdoor unit onto the copper
pipes.
Flare the pipe with extra length above the flaring tool as
shown in the table.
The flared edge must be even and not cracked or
scratched.
Piping Works
Do not use contaminated or damaged copper tubing. Do not remove plastic, rubber plugs and brass nuts from the valves,
fittings, tubings and coils until you are ready to connect suction or liquid line into valves or fittings.

SPECIAL PRECAUTIONS WHEN DEALING WITH R407C UNIT
R407C is a zeotropic refrigerant mixture which has zero ozone depletion potential and thus conformed to the Montreal
Protocol regulation. It requires Polyol ester oil (POE) oil for its compressor's lubricant. Its refrigerant capacity and perfor-
mance are about the same as the refrigerant R22.
POE oil is used as lubricant for R407C compressor, which is different from the mineral oil used for R22 compressor.
During installation or servicing, extra precaution must be taken not to expose the R407C system too long to moist air.
Residual POE oil in the piping and components can absorb moisture from the air.
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.
No additional charge of compressor oil is permitted.
No other refrigerant other than R407C.
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
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.
All wires must be firmly connected.
All wires must not touch any of the refrigerant piping, compressor or any moving parts of fan motor.
The connecting wires between the indoor unit and the outdoor unit must be clamped on the wire clamps as shown
in the figure.
The power supply cord must be equivalent to H05RN-F (245IEC57) which is the minimum requirement.

VACUUMING AND CHARGING
Purging 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
pump.
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 -76mmHg (0~76mmHg).
Caution
Wait for 15~20 minutes to check whether the gauge
reads a constant vacuum level. If gauge raeding
indicates higher level again, it means the presence of
water in the pipe, or leakages. In this case, remove
the water or check the leakages. After rectification,
repeat the above steps until a stable vacuum level.
Close the valve of the changing gauge and stop the
vacuum pump.
On the outdoor unit, open the gas valve (3 way) and
liquid valve (2 way) (in anti-clockwisw direction)
with 4mm key for hexagon sacked screw.

Charge Operation
This operation must be done by using a gas cylinder and a
precise weighing machine obligatorily. The additional
charge is topped-up into the outdoor unit using the suc-
tion valve via the service port.
Remove the service port cap.
Connect the low pressure side of the charging gauge to
the suction service port center of the cylinder tank and
close the high pressure side of the gauge. Purge the air
from the service hose.
Start the air conditioner unit.
Open the gas cylinder and low pressure charging valve.
When the required refrigerant quantity is pumped into the
unit, close the low pressure side and the gas cylinder valve.
Disconnect the service hose from service port. Put back
the service port cap.
Additional Charge
The refrigerant is pre-charged in the outdoor unit. If the
piping length is less than 7.62m, then additional charge af-
ter vacuuming is not necessary. If the piping length is more
than 7.62m, then use the additional charge valve as indi-
cated in the table below.

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.
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.

Dry Mode
When the air humidity is high, the unit can operate in
dry mode. Press <MODE> button and choose <DRY>.
If the room temperature is 2°C higher than the set
temperature, the air conditioner will operate under
cooling mode until it reaches within the 2°C range of
difference compared to the set temperature before it
converts to dry mode.
If the room temperature is within the 2°C range of
difference compared to the set temperature, it will
directly operate under dry mode.
The unit will operate at LOW speed under dry mode.
Heat Mode (for heat pump unit only)
When the unit is switched on from cold start or
defrosting cycle, the indoor fan will start to operate only
after the coil reaches the desired temperature.
When the set temperature is achieved, the indoor fan
will operate until the coil cannot provide anymore
additional heat.
Overheating Protection (for heat pump unit only)
In case the internal and/or the external temperature is to
high, or that the filter is dirty and clogged up, the
refrigerant may be overheated. The compressor will cut
out when the condensing temperature reaches 62°C.
Frost Prevention
When the air filter is dirty, the evaporating temperature
