6. PERFORMANCE TABLE
Interpolation and Extrapolation method can be used to get the total capacity, TC and sensible capacity, SC
at those temperatures which are not stated out in the table.
Example:
Model: ACM 20E - ALC 20C
Indoor Condition: 23°C DB, 15°C WB
Outdoor Condition: 37°C DB
Solution:
Overall
Based on the Performance table on Pg. 37,
1. Refer to the Indoor DB column,
- 23°C is located between 20°C and 24°C (Thus, Interpolation need to be applied)
2. Refer to the Indoor WB column,
- 15°C only available in the case of Indoor DB = 20°C. (Thus, Extrapolation between 16°C WB
and 17°C WB during 24°C indoor DB is required)
3. Refer to the Outdoor DB column,
- 37°C is located between 35°C and 40°C. (Thus, Interpolation need to be applied)
Please follow the steps below in order to get the required capacity.

11. INSTALLATION
Caution
Sharp edges and coil surfaces are potential injury hazard. Avoid from contact with them.
(1) Installation of Indoor Unit
Preliminary Site Survey
xElectrical supply and installation is to confirm to local authority's (e.g. National Electrical Board) codes and
regulations.
xVoltage supply fluctuation must not exceed ± 10% of rated voltage. Electricity supply lines must be independent of welding transformers which can cause high supply fluctuation.
xEnsure that the location is convenient for wiring, piping and drainage.
Standard Mounting
Ensure that the overhead supports are strong enough to hold the weight of the unit. Position the hanger rods
(wall mounting bracket for floor standing), and check for its alignment with the unit as shown in Figure A. Also,
check that the hangers are secured and the base of the fan coil unit is leveled in both horizontal directions,
taking into account the gradient for drainage flow as recommended in Figure B.
Figure A
44
Please ensure that the following steps are taken:
x Check the gradient for drainage flow as recommended in Figure B.
x Provide clearance for easy servicing and optimal air flow as shown in Figure C.
x The indoor unit must be installed such that there is no short circuit of the cool discharge air with the warm
return air.
x Don not install the indoor unit where there is direct sunlight shining on the unit. The location should be
suitable for piping and drainage installation. The unit must be a large distance away from the door.

(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 :
x
Install the condensing (outdoor) unit in a way 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.
x
Ensure that there is no obstruction of air flow into or out of the unit. Remove obstacles which block air intake or
discharge.
x
x
x
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.
x
The location must not be susceptible to dust or oil mist.

(3) REFRIGERANT PIPING
MAXIMUM PIPING 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 compressor may become defective. Always choose the shortest path and follow the recommendation as tabulated below:

Wiring regulations on wire diameters differ from country to country. Please refer to your LOCAL ELECTRICAL CODES for field wiring rules. Be sure that installations comply with the rules and regulations.
GENERAL PRECAUTIONS
x
x
x
x
x
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 disconnects 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.
(5) VACUUMING AND CHARGING
The pre-charged outdoor unit does not need any vacuuming or charging. However once it is connected, the
connecting pipe line and the indoor unit need to be vacuumed before releasing the R22/R407C/R410A 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).
Note : R407C – Fix filter dryer
R22 - Nil
R410A - Nil
(6) ADDITIONAL CHARGE
x
x
The refrigerant charge has already charged into the outdoor unit. For the piping length of 7.6m, additional

(9) SPECIAL PRECAUTIONS WHEN DEALING WITH REFRIGERANT R410A UNIT
i)
WHAT IS NEW REFRIGERANT R410A?
R410A is a new HFC refrigerant which does not damage the ozone layer. The working pressure of this
new refrigerant is 1.6 times higher than conventional refrigerant (R22), thus proper installation / servicing
is essential.
ii) COMPONENTS
Mixture weight composition R32(50%) and R125(50%)
iii) CHARACTERISTIC
x
R410A 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 R410A.
x
When refrigerant R410A is used, the composition will differ depending on whether it is in gaseous or
liquid phase. Hence when charging R410A, ensure that only liquid is being withdrawn from the cylinder or
can. This is to make certain that only original composition of R410A is being charged into the system.
x
POE oil is used as lubricant for R410A compressor, which is different from the mineral oil used for R22
compressor. Extra precaution must be taken not to expose the R410A system too long to moist air.
iv) CHECK LIST BEFORE INSTALLATION/SERVICING
x
Tubing
Refrigerant R410A is more easily affected by dust of moisture compared with R22, make sure to temporarily
cover the ends of the tubing prior to installation
x
Compressor oil
No additional charge of compressor oil is permitted.
x
Refrigerant
No other refrigerant other that R410A
x
Tools (size of service port is different from R22 system)
Tools specifically for R410A 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
v) HANDLING AND INSTALLATION GUIDELINES
Like R22 system, the handling and installation of R410A 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 its hydroscopic POE oil, additional
precautions must be taken to ensure optimum and trouble free system operation.
a) 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.
b) 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.
c) 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.
55
d) When charging R410A, ensure that only liquid is being withdrawn from the cylinder or can. This is to
ensure that only the original composition of R410A is being delivered into the system. The liquid
composition can be different from the vapor composition.
Invert cylinder
without dip-pipe

withdrawal
f)
Normally, the R410A 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.

–
–
Inspect thoroughly and clean indoor and outdoor units.
Clean or replace air filters.
Clean condensate drain line.
Clean clogged indoor and outdoor coils.
Check fan imbalance before operation.
Tighten all wiring connections and panels.
Check for refrigerant leakage.
The design of the ALC outdoor series allows servicing to be carried out readily and easily. The removal of
the top/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.

By means of diagnostic flow chart:
Generally, there are two kinds of problems, i.e. starting failure and insufficient cooling/heating. “Starting failure”
is caused by electrical defect while improper application or defects in refrigerant circuit causes “Insufficient
cooling / heating”.
i) Diagnosis of Electric Circuit
The most common causes of air conditioner failure to “start” are :
a) Voltage not within ±10% of rated voltage.
b) Power supply interrupted.
c) Improper control settings.
d) Air conditioner is disconnected from main power source.
e) Fuse blown or circuit breaker off.
61
ii ) Diagnosis of Refrigerant Circuit / Application
There might be some causes where the unit starts running but does not perform satisfactorily, i.e. insufficient
cooling. Judgement could be made by measuring temperature difference of indoor unit’s intake and discharge
air as well as running current.
