Aircommand Australia: How to identify units


Roof Top Units
Model	Notes	Distinguishing Features
1800 Series	Produced between 1979 and 1982. Made with a steel chassis and a moulded polyurethane clam shell evaporator section. This model had a ABS plastic nose cone.	The 1800 Series was the only roof top model to have a metal chassis.
1900 Series	Produced between 1982 and 1987. Fully moulded polyurethane case that was higher at the back than the front. The bottom casing was black and top white. This unit had a separate clam shell evaporator moulding as per the 1800, a reciprocating compressor and single motor for evaporator and condenser fans. The fascia had a lever used to baffle air flow rather than a switch to control fan speed.	1. Moulded casing combined with a separate clam shell evaporator section moulding. 2. Reciprocating compressor. 3. Different fascia
2000 Series	Produced between 1987 and 1992. This was the first model using the low profile casing which incorporated the clam shell evaporator moulding. The unit had a rotary compressor and separate condenser and evaporator fan motors. The shade pole motors used a red speed 110 Ohm speed control resistor these motors were then replaced with capacitor start motors that used a green 500 Ohm speed control resistor. The plenum was changed to incorporate all around return air and rotary switches.	Distinguished from earlier models by 1. Rotary compressor 2. New low profile casing 3. Separate fan motors This model can only be distinguished from the 2100 series with the serial number, however the main issue for spare parts is to determine the type of fan motors. Red speed control resistor means shaded pole motors, green resistor means capacitor start motors.
2100 Series	Produced between 1992 and 1995. As per the last of the 2000 series. This included identical capacitor fan motors. These are distinguished from the earlier 2000 series by using a green 500 Ohm speed control resistor.	Distinguished from series 5000 units by having only a single circuit evaporator.
2200 Series	This series is the models of cooling only roof top air conditioners. These are most easily distinguished by the absence of a reversing valve in the hermetic system.	No reversing valve.
2300 Series	Produced between 1994 and 1999. These units had electronic controls.	Electronic circuit board used to control the air conditioner
5000 Series	Produced from 1995 to the present. These units have twin circuit evaporator coils and the condenser fan is of a pull through design.	Twin circuit evaporator coil.
Kestrel Under Floor Units
2800 Series	Produced between 1985 to 1991. This under floor unit had the controls under the return air grille in the floor.	Controls in the unit under the floor.
2900 Series	Produced between 1991 and 1994. This unit had the controls in a remote switch box. Most units contained the normal mechanical thermostat, however a few units were produced with an electronic thermostat. In both cases the switch box had 3 controls.	Remote control box with 3 separate switches.
2950 Series	Produced between 1994 and 1997. This utilized fully electronic controls. The remote switch box had only 2 controls.	Remote control box with 2 separate switches.
Osprey Ducted Units
3000 Series	Produced between 1988 and 1990. This unit had a base made from moulded polyurethane.	Moulded base
3100 Series	Produced between 1990 and 1994. The moulded base was replaced with a metal base.	Metal base and plastic lid
3200 Series	Produced between 1991 and 2001. The ABS plastic lid was replaced with a metal lid. There were other internal changes. The 3200 series is defined as a right hand unit, this means that if you are inside the van, looking at the unit the ducting comes out the right hand side.	Metal base and metal lid as per 3300 series except right hand unit.
3250 Series	Produced between 1994 and 2000. This unit has fully electronic controls and is a right hand unit.	Metal case, metal lid, controls use an electronic circuit board same as 3350 series except right hand.
3300 Series	Produced between 1994 and 1999. As per the 3200 series except that this is a left hand unit. This means that if you are inside the van, looking at the unit, then the ducting comes out the left hand side.	Metal base and metal lid as per 3200 series except left hand unit.
3350 Series	Produced between 1996 and 2000. This unit has fully electronic controls and is a left hand unit.	Metal case, metal lid, controls use an electronic circuit board same as 3250 series except right hand.
Heron Split Systems
4000 Series	Produced between 1996 and 2000. This was the first model Heron 2.2. The air handler was fitted behind the front panel in the cupboard as distinct from the later design where the air handler fitted though the front panel.	Distinguished from the Heron 3.0 models by the low profile condenser set designed to go under a bunk. This model is distinguished from later Heron 2.2 Models by the air handler design.
4100 Series	Produced between 1998 and 2001. This was the first Heron 3.0. The air handler was fitted behind the front panel in the cupboard as distinct from the later design where the air handler fitted though the front panel.	Distinguished from the Heron 2.2 models by the condenser set which is designed to be accessed from outside the van. This model is distinguished from later Heron 3.0 Models by the air handler design.
4200 Series	Produced between 1999 and now. This is a Heron 2.2 and the air handler is fitted through the cupboard front panel as opposed to the earlier design where it was fitted behind this panel.	Distinguished from the Heron 3.0 models by the low profile condenser set designed to go under a bunk. Distinguished from the 4000 series by the air handler design.
4300 Series	Produced between 1999 and 2001. This is a Heron 3.0 and the air handler is fitted through the cupboard front panel as opposed to the earlier design where it was fitted behind this panel.	Distinguished from the Heron 2.2 models by the condenser set which is designed to be accessed from outside the van. This model is distinguished from earlier Heron 3.0 Models by the air handler design and later models by the compressor.
4500 Series	Produced between 2001 and now. This is a Heron 3.0 and the air handler is fitted through the cupboard front panel as opposed to the 3100 series where it was fitted behind this panel. This model has a Siam compressor which can be distinguished from the compressor used in the 4300 series by the absence of a compressor overload on the top.	Distinguished from the Heron 2.2 models by the condenser set which is designed to be accessed from outside the van. This model is distinguished from earlier Heron 3.0 Models by the air handler design and by the compressor.
4700 Series	Produced between September 2003 and March 2005. This was an upgrade on the Heron 3 and included the electronic remote control and propeller condenser fan.	The condenser is easily distinguished by the different grill used to house the propeller fan and the electronic remote control.
4710 Series	Produced after March 2005 and was the same as the 4700 series except that the electronic card is different.	The control cable to the fascia has an 8 pin plug whereas the cable was joined with a 6 pin plug in the 4700 Series.
4800 Series	Produced between 2000 and now. This appears the same as the 4200 series except it is produced to comply with European standards. Importantly this includes different gas and different wiring.
4900 Series	Produced between 2000 and now. This appears the same as the 4300 series except it is produced to comply with European standards. Importantly this includes different gas and different wiring.
