General Description
OPTIONAL EXTRAS - GENERAL
Coil Guards Guards can be fitted to each of the outer condenser coils to protect against damage.
Electronic Soft Start The electronic soft start enables the unit compressor motor to be ramped to speed with
the minimum full load current. Further benefits include removal of nuisance tripping,
supply voltage dips and motor overheating.
Emergency Stop Can be factory fitted to the electrical control panel of the evaporator section.
Return Air Fan Direct driven speed controllable short case axial fan with efficient 3 phase rotor motor
technology and finger guard grilles. Factory fitted and located below the return air duct
aperture to ensure re-circulation of air in the conditioned space and powered exhaust air
during free cooling operation.
The system is fitted with a voltage regulating fan speed controller which allows set-point
adjustment and system monitoring via the
microprocessor controller.
Optionally, speed control can be provided by energy efficiency inverter drives, refer to
Inverter Driven Axial Fans - Condenser & Return Air Fan Section , on page 16.
Constant Air Volume Design to maintain system air volumes regardless of system pressure drops, in particular
where there is increased resistance due to dirty filters. In addition, commissioning set up
times are reduced. Operating air volume can be viewed via the microprocessor
display/keypad.
Supply Air Fan Supply air fan speed can be modulated to maintain a constant air volume by the
differential pressure between the case and fan inlet ring being monitored via the unit
microprocessor.
The control signal to the supply air fans is automatically adjusted to maintain design unit
air volume.
Air Volume Adjustment Designed to facilitate on site adjustment of the return air volume. In addition,
commissioning set up times are reduced. Operating air volume can be viewed via the
microprocessor display/keypad.
Return Air Fan Return air fan speed can be manually adjusted to maintain a constant air volume via the
unit microprocessor by the fitting of a velocity sensor in the return air duct, supplied loose
for on site fitment.
Weather Louvres - Split
System A weatherproof louvre is recommended for fitting to outdoor units with fresh air intake and
exhaust air, to protect internal components.
Complete with bird mesh.
R410A Leak Detection
System A factory calibrated and fitted leak detection system fitted in the compressor section, will
raise an alarm when refrigerant gas is detected.
