Installation and Maintenance Manual
8
The Fresh Air intake should be positioned clear of any objects which could obstruct the airflow and
be away from any exhaust discharge ducts from the unit or any adjacent equipment.
The Fresh Air inlet should be fitted with a weather shelter and inlet and exhaust points should be
minimum 6 m apart.
Noise Levels
Do not sit unit adjacent to sleeping quarters unless background noise levels have been checked
and permitted by the appropriate authority.
It is recommended that rubber supporting or vibration absorbing pads are used to support the unit
to minimise any vibration being transmitted into the building structure. We recommend wafer pads
be used under the frame. We also recommend flexible couplings be fitted to the supply and return
ducts to reduce vibration transfer.
Drainage
IMPORTANT
Installation of a “P” Trap is mandatory for all drainage points. Air Change will not
accept any liability for any water damage resulting from incorrect installation. A
minimum of 50 mm elevation difference between three levels are required. Schematics
are as follows.
All drainage needs to be trapped (standard “P” trap). Prior to start up, charge the external “P” trap by
pouring several litres of water into the drip tray, allowing run off to seal the drain outlets to prevent
outside air being drawn into the unit.
