• Aircommand HERON 2.2, 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.

Both, or either end of the con/set may be hard against a wall or panel, but the back of the unit must have sufficient clearance to allow easy access to the line valves (see fig. 4).

Pipe work may be run internally to the A/H, or may be run through holes in the floor and run externally to a convenient re-entry point, or the pipes may be built into the wallspace during van construction. NB. Pipework installed in walls must be well insulated to avoid “sweating” and possible long term moisture damage. The control wiring will normally follow the pipework and be taped to it. NB. I
