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.

Sparrow Mk4 unit on the roof of the vehicle, distances shown are calculated from a
14” square hole (360 x 360mm).
- The above outline on the right shows the minimum clearance required around
the 14” square hole (360 x 360mm) in order to accommodate the plenum.
There should be a minimum of

service access and air flow to
condenser.
