INSTALLATION OF WM-ERV
2.1
Location
2.1.1 General
•
The ventilation unit is located through an outside wall or suitable window
•
The WM-ERV package is marked with stickers “Fresh air” “Supply Air”,
“Return Air” and “Exhaust Air” showing the air path through the unit.
2.1.2 Internal Inlet/Outlet Considerations
•
Whenever possible, the unit should be located where the fresh air can be
mixed with the refrigerated air from the air conditioner.
•
The prime function of the unit is to deliver pre-conditioned fresh air by
transferring the energy from the cold stale return air. Therefore the unit must
be located away from where the cold return air can be affected by a heat
source i.e. a frequently opening door to exterior, or near any major source of
heat generation.
•
The introduced fresh air should also be above head height to avoid blowing directly
on to occupants.
2.1.3 External Inlet/Outlet Considerations
•
The exhaust discharge should be directed in a clear path away from any
windows that can be opened.
•
Location of the fresh air inlets should adhere to the Australian Standards
1668.2 Code.
•
The fresh air intake should be positioned clear of any objects which could
obstruct the airflow and be clear of any polluted air from other units, exhaust
fans, kitchen or toilet exhausts, etc
.
•
When the unit is fully installed, make sure the outside inlet grille opening and the
return air inside are completely free and not blocked off in any way.
