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.

Allen key

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.

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

will decrease and eventually cause frosting.

• The LED light will blink to indicate that the filter is

dirty. If the evaporating temperature reaches 0°C, the

unit will trip and defrost.
