INSTALLATION INSTRUCTIONS FOR HERON 2.2
The Heron 2.2 is suitable for installation in most caravans & motorhomes. Installation in Commercial and
Industrial vehicles and equipment should be referred to AIRCOMMAND AUST for assessment of
suitability. The Heron System must be installed in accordance with national wiring regulations.
The capacity of the airconditioner to adequately cool or heat a van, is dependent on:
• The size of the van or vehicle.
• The thickness and quality of thermal insulation installed in the van.
• The expected outside or ambient conditions.
The Heron 2.2 is recommended for vans up to 5.2 m overall, but
assumes that wall and ceilings are insulated with a minimum of
25 mm of insulation, wool or foam. The Heron 2.2 may be used
in vans up to 7 metre provided the insulation is a minimum
38mm thick and all windows are double insulated. Windows
should all have shades or curtains as a minimum.
If the van is to be used mainly in extreme conditions (40°C plus),
then be conservative, i.e. ensure the best insulation is installed,
consider double glazed windows, and size the airconditioner
down to 4.8 m maximum.

handler
The A/H and CON/SET are coupled by means of a pair of
refrigerant lines, and a control cable. The pipework is not
supplied with the unit, but a standard 7 m control cable is.
Before proceeding with the installation, consider a number of important details that must be complied with
in the following description.
CHOOSING A POSITION FOR THE CON/SET
Generally, avoid installation on the left hand side (awning side), as the condenser set will discharge hot air
into this space.
Australia & UK (LHS of road) it is usual to install the con/set on the right hand side, either under a bunk,
settee or at the bottom of a floor cupboard. Conversly, continental Europe (RHS of road) the con/set should
be on the left hand side.
NOTE: Ensure that wherever the con/set is installed, reasonable access to the top of the unit is always
available, for service, and any shelving etc. above, must be easily removed. Also, the two line valves on the
back of the unit must be easily accessed.
The maximum length of pipework between the Con/set and the A/H is 5 metres. Installations exceeding this
may require extra refrigerant to be added to the system.
