TYPICAL INSTALLATION EXAMPLE
MECHANICAL SPECIFICATIONS
General
All units are factory assembled, piped, internally wired.
They are also tested and checked under a strict quality
control system in the factory.
Exterior surfaces of all units of outdoor unit are
phosphatized, zinc-coated steel with powder coating
and ivory white baked enamel finish.
Refrigeration Controls
Refrigeration controls include condenser fan,
evaporator fan and compressor contactors.
Compressors
All units have high efficiency type hermetic line starting
compressors.
Compressors are equipped with thermal overload
protector, over-current relay and high pressure
protection control.
Crankcase heaters are standard.
Evaporator Coils
Highly efficient cross-finned coil are applied to provide a
larger cooling capacity with low air speed on the coil.
Coils are made of 9.52mm OD and 0.35mm thick
seamless copper tubing mechanically bonded to 0.12mm
thick aluminium fins and are factory leak tested at a
pressure of 3.3MPa.
They are provided with strainers
attached to the capillary tubes to further ensure a clean
system.
Condenser Coils
Unnecessary power input due to higher discharge
pressure is avoided by high performance designs of
cross-finned coil.
Condenser coils are made of 9.52mm OD, 0.35mm
thick seamless copper tubes mechanically bonded to
0. 12mm thick aluminium fins and factory pressure
and leak tested at 3.3MPa.
Evaporator Fans
The sirocco fans are made of galvanised steel and
balanced to proved accurate air flow performance at
low noise level.
Condenser Fan
The direct-drive propeller fan is dynamically balanced,
to ensure smooth airflow.
A weatherproof three-phase squirrel cage induction
motor is used to drive the condenser fan.
