Condenser Technical Manual 6666879 V1.2.0_05_2013

CR12 - CR165 50/60HzCONDENSERS
Electronically Commutated (EC) Fan Motor
Sickle bladed fan assemblies with integral long bellmouth and ngerproof grille. Incorporates external EC rotor motor
technology to provide highly accurate discreet speed control. The fans o󰀨er maximum airow performance while
keeping sound levels to a minimum.
Each fan incorporates electronically commutated DC motor control using semi-conductor modules responding to a
signal from the Airedale indoor unit.
EC motors are DC motors with integrated ac to DC conversion; this gives the exibility of connecting to ac mains with
the e󰀩ciency and simple speed control of a DC motor. The EC fan o󰀨ers signicant power reduction in comparison
with equivalent ac fan at both full and modulated fan speeds. The inbuilt EC fan control module allows for fan speed
modulation from 15-100%, the modulating range of a standard ac fan is typically 40-100% of full fan speed.
IMPORTANT
All fans are supplied pre-programmed to a head pressure setpoint of 26 barg and proportional band setpoint of 6 barg.
For alternative settings, please specify at order.
Short Case Axial Fans
Short case axial fans can be supplied for indoor installations where discharge air requires to be ducted to an outdoor
location. The fans will meet duty plus 75Pa of external static pressure.
Head pressure control is maintained by a modulating fan speed controller tted to the outdoor unit. The controller is
rated to IP54 for outdoor use and will operate accurately in ambient temperatures down to a minimum of -20°C.
Corrosion Resistant Coated Coils
For aggressive atmospheres a corrosion resistant coating can be applied to the aluminium ns.
Head Pressure Control
(On / O󰀨) Head pressure control is maintained via a factory tted on/o󰀨 pressure switch rated to IP54 for outdoor
use as standard. Good control with ambients down to 0°C, below this temperature variable speed controllers are
recommended.
The head pressure is factory set to 26 barg (377 psig).
Shut O󰀨 Valves
Where unit isolation for easier maintenance is required, shut o󰀨 valves can be supplied loose for on site tment.
Coil Guards
Protective mesh guards can be tted to each of the outer coils to protect against damage.

CR12 - CR165 50/60Hz CONDENSERS
Installation Data
Positioning
• Unit must be positioned on an even base to ensure correct operation
• Observe airow and maintenance clearances
• Where multiple units are installed, due care should be taken to avoid the discharge air from each unit adversely
a󰀨ecting other units in the vicinity
• When mounting the units adjacent to a wall or other vertical surface the condenser should be positioned with the
coil side facing the wall
• Check all services are present and accessible
Mounting
Fix the condenser down using the appropriate bolt holes in unit xing legs.
Siting Recommendations
Horizontal air discharge
• Avoid where possible siting the unit where wind and air re-circulation may interfere with the fan operation
• A vertical air discharge unit is recommended for installation in windy locations or wherever a horizontal airow
would be obstructed
Pipework Connections
CAUTION
Take care that the service connections are correctly made and in particular do not invert the inlet and outlet connections.

Holding Charge
The units are shipped with a holding charge of inert gas to guard against contamination or moisture during shipping and
storage.
CAUTION
The charge should be checked to indicate if leaks are present prior to evacuation.
If the charge appears to be either partially or totally lost, then the unit should be carefully checked for signs of physical
damage.
General
Run the refrigeration lines taking care to ensure the following:
• Use straight line routes where ever possible
• Refrigerant lines should be insulated in areas of high / low temperature or when exposed to direct sunlight
• When insulating refrigerant lines, cut approximately 30 - 50cm longer than the distance between the units to
ensure the insulation goes right upto the unit, leave connections uncovered for leak testing
