Install & Operation Manual
Ventilation Grill Installation
When Borg & Overström u2 undercounter
units are installed inside a cabinet or housing,
adequate ventilation is recommended to ensure
that they operate satisfactorily.
During a cooling cycle it is normal for the
unit to produce heat and the purpose of
the ventilation is to provide a supply of
air that can absorb the generated heat
which otherwise will accumulate inside the
cabinet or housing and reduce the cooling
performance of the unit. The amount of heat
generated by the cooling cycle depends
directly upon the amount of usage – the
higher the usage, the more heat produced.
To provide adequate ventilation we
recommend that air grilles/vents are fitted
as supplied (or vent apertures formed) in
the cabinet to allow an airflow as shown
below. Normally this should be enough for
all situations.
The air grilles fitted (or vent apertures formed)
should each have a ventilation area equal
to or greater than 25000mm2 and the air
circulation path inside the cabinet/housing
must be unobstructed. (eg: a vent grille with
an overall size of 250mm x 100mm).
It is recommended that an inlet vent grille is
set into the plinth with a corresponding vent
grille in the base of the cabinet behind the
undercounter unit to allow the air to flow
past the condenser. An exhaust vent grille is
also required at the top if the cabinet. It is
recommended either behind the tap in the
work surface or at the side of the cabinet for
a more unobtrusive appearance should this
area be available.
