INSTALLATION
Locating Equipment
It is important to ensure that adequate access is provided around the perimeter of the
AHU for maintenance purposes as follows:
Access Side of Unit
Sufficient room at the access side of the unit is required for removal of the largest
component within the AHU
Back of Unit
Double width units require access to the front and back, therefore access requirements
apply as above. Where access to components is not require

Air Intake/Discharge
Allow sufficient room for cowls to fit (dimensions as detailed on the general
arrangement drawing). We also recommend an additional distance equal to the unit
width before any obstacle to prevent recirculation of the exhaust air into the fresh air
inlet.

the installer and dependant of the site conditions. Flexible connections are NOT
recommended for connecting ductwork to the unit, as the fan outlet is fitted with a
flexible connector and is isolated from the unit via anti-vibration mounts. Provision
must be made for a cleanable drain trap which should terminate at an open drain or
