█General
–Fabricated with a rigid galvanized steel casing.
–Single skin galvanized steel casing with 10mm thickness,
25 kg/m3 high-density non-flammable PE insulation for the indoor unit.
█Motor
–The single phase motor is consisted with hermetic aluminum alloy casing
and permanently lubricated ball bearing.
- The motor has class B insulation ; with internal thermal protection.
– Motor lead-out wires are with sleeve, providing protection against damage
–The 3 phase motor has Class F insulation, with IP55 protection index
█Drain Pan
–The drain pan is 45~50mm depth with 1.0mm thickness galvanized steel
c/w internal epoxy polyester resin coating.
–The drain pan is sloped towards the drain pipe with a 2 deg. gradient.
–The drain pan has one 3/4-inch to 1-1/4-inch male pipe thread (BT) connection.
– The standard insulation material is 10mm thickness, 25kg /m density PE foam.

Field Copper Tubing Connection
To ensure satisfactory operation and performance, the following points should be noted for the field
tubing arrangements of the complete refrigerant cycle.
a) Liquid loops or oil traps must be provided according to the position of the outdoor and the indoor
units (depending on whether the indoor unit is above or below the outdoor unit).
b) Field supplied filter drier must be installed as close to the expansion valve(s) of the indoor
unit (evaporator) as possible.
c) Field supplied sight glass must be assembled and mounted next to filter dryer.
d) Pipe size shall be followed as listed in page
When the pipe is too long, the required refrigerant quantity increases, both the capacity and
reliability of compressor will drop.
Maximum tube length and Maximum number of Bends
,,
When the number of bends increases, refrigerant flow resistance increases, thus lowering the cooling
capacity; the excessive pressure drop might eventually cause the failure of compressor.
If height difference of evaporator and condenser is excessive, this will retard the compressor oil return
and affecting the compressor efficiency
Cautions: All units installation length
Max elevation 20M
Max total equivalent length 35M
Max bends 8
For operation safety, accumulator is recommended to be added for any installation more than 30m in
len

Field Charging & Refrigerant Handling
Scroll compressors have a very high volumetric efficiency and quickly pump a deep vacuum if there is
insufficient refrigerant in the system or if refrigerant is added too slowly. Low suction pressure will lead
to high discharge temperatures.
This process will casue the scrolls are not being well-lubricated eventually leads to high friction
between the scroll flanks and tips and generates additional heat.
This will cause damage to scroll bearing which can occur in less than one minute. But the failure might
occur only in later of time after charging.
Other typical field charging problems include undercharging, overcharging, moisture or air in the
system etc. In time each one of these problems can cause compressor failure.
Equipment
Minimal equipments are required for field charging. to do a satisfactory job is :
Set of service gauges Hoses , Vacuum pump, Charging Cylinder
Scales Thermometer Vacuum gauge
Always choose the shortest piping path with minimum bends.
• Both indoor and outdoor are brazed connection.
Warning:
• Make sure there is no flammable gas at the surrounding before the brazing work started.
• DO NOT charge in flammable gas.
Caution:
• During the preparation, piping shall be properly covered to avoid the containmination of the system.


Unit InstallationUnit Installation
Charging Hose
Most field-charging is done using standard service hoses. Hoses are made in different colors with
different working pressures and with different leak rates but the most important point is the presence
or absence of hoses
This slows evacuation and vapor charging dramatically. In most cases the Shredder depressor can
be removed but it is simpler to have one set of hoses with and one set without Shredder depressors
Hose selection is important depending whether the system is being evacuated or charged. Charging
liquid from the cylinder into the liquid line should be carried out using an open hose connected to an
unrestricted fitting. This will reduce charging time.
The proper refrigerant charge should follow the volume as recommended by manufacturer , addtional
charge for extended length installation can follow general guideline below.
If the installer cannot find the correct charge but the system must be started, refrigerant should be
carefully added to the system until reasonable sub-cooling is measured in the liquid line and reasonable
suction superheat is measured at the compressor suction. Suction and discharge pressures must be
monitored carefully during the charging process.
Additional Chage
Based on liquid pipe size per meter length:
Liquid line size kg
1/2” 0.10
5/8” 0.17
3/4” 0.26
7/8” 0.37
Above is the recommendation, actual charge level may be different due to the different application
and ambient condition.
Refrigerant R410A : special precaution
R410A is HFC refrigerant which has Zero Ozone Depletion Potential (ODP = 0). The working
pressure of this refrigerant is 1.6 times higher than refrigerant (R22), thus proper installation /
servicing is essential
i) Characteristic
Mixture of composition by weight : R32(50%) and R125(50%)
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.
It is NOT recommended to add new refrigerant to leaked system.
System shall be evacuated thoroughly and recharging with liquid refrigerant (original mixture
composition of R410A ).
Polyol-ester (POE) oil is used as lubricant for R410A compressor. As the water will react with POE
oil and become acid.Extra precaution must be taken to avoid exposing the R410A system to moist air.
How much refrigerant?

Unit InstallationUnit Installation
Charging Hose
Refrigerant R410A : special precaution
ii) Check List Before Installation / Servicing
• Tubing -Refrigerant R410A is more easily affected by dust or 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.
• Tools - Tools used for R410A only (must not be share with other refrigerant)
Gauge manifold and charging hose ,Refrigerant cylinder/charging cylinder
Vacuum pump c/w adapter, Refrigerant recovery machine etc
iii) Handling and Installation Guidelines
Like R22 systems, 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.
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.
e) 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.
