1. INSTALLATION POSITION
Fig 1: Sparrow Mk4 clearances required around roof top unit
Before beginning, mark out the position of the unit
considering the following important requirements:
- The air conditioner should be situated as
centrally as possible on the van, to ensure even air
distribution.
- The Sparrow Mk4 may be oriented in any
direction to the normal direction of travel
- When considering the installation position
remember to check for clearance around the
plenum inside the van.
- Avoid an installation position where a bulkhead,
cupboard or light fitting could interfere with the
discharge air flow from the plenum.
- Avoid an installation where a roof joining seam
crosses through the 14” square installation cut
out.
It is important that the unit is never
more than 5° from the horizontal and the
rear of the unit should never be higher
than the front when in use.
- Contact Aircommand if your installation differs
significantly
