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 capacity of the airconditioner to adequately cool or heat a van, is dependent on:
• The size of the van
• 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. 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.
