Installation

NB! The installation engineer is responsible for
ensuring that the air handling unit is properly secured.
NB! The installation engineer is responsible for
ensuring that any existing functions in the wall/ceiling
(e.g. vapour barrier) are restored and fully functional
once the unit has been installed.
NB! Read this section "Installation" fully before
starting installation!
NB! The walls and floor at the place of installation of
the Airmaster air handling unit must be even and level.

Duct Holes

NB! It is recommended that the duct holes be drilled
10-15 mm larger than indicated on the drawings as
this will allow for subsequent insulation, will prevent
direct contact with the wall, and will allow for a vapour
barrier, etc., to be restored.
A rubber diaphragm for restoration of the function
of the vapour barrier is optional available and can be
delivered by Airmaster.
Important! Duct holes in the wall must have an outward
downward gradient of 1-2% to prevent heavy rain
from entering the unit.
1. Marking the holes for the ducts.
Dimensions for duct hole positioning can be found in
"Appendix 1 Dimensional Drawings"
