INSTALLATION
Location
General
The PCU unit is marked with stickers “SA” (Supply Air), and “OA” (Outdoor Air), showing the air
path through the unit.
The Fresh Air supply inlet should be clear of any polluted air from other units, exhaust fans, etc.
Level and Suitable Base
These units are primarily designed to be fitted on a suitably reinforced support base of sufficient
strength to adequately take the full operating weight of the equipment.
The unit must be mounted on a level base and any slope should not 25 mm over the unit's
dimensions to ensure proper condensate drainage.
On rooftop applications, the unit must sit at least 152 mm above the roof surface. Place the unit
above a load bearing wall. Arrange supporting members to adequately support the unit and
minimise the transmission of vibration to the building.
Suspending the Unit
Before suspending the unit, check the supporting beams to be used and verify that it has sufficient
load carrying capacity to support the weight of the unit.
Access for Maintenance
The unit must be mounted so maintenance personnel can gain access to all parts of the unit and
with sufficient room to remove fans, compressors, coils or heat exchangers as required.
Minimum space requirements:
̵
600 mm for electrical access;
̵
1000 mm from Fresh Air inlet;
̵
1000 mm from all access doors on the unit in accordance with the design and construction to
allow servicing or removal of parts.
Ductwork Considerations
The unit must be situated close to the point of use to prevent unnecessary long runs of ductwork.
Fresh Air Inlet Precautions
The location of the Fresh Air inlets should adhere to AS1668.2.
