6.1.7 Installing the IR
radiation filter glass kit
This section describes how to install the IR
radiation filter glass. The kit consists of a pair
of IR filter glasses and a special front flange
with air barrier that is different from the
standard one, which should be replaced.
Dismantle the front flange of the
housing by unscrewing the 4 screws
using the allen wrench supplied.
Position the glass pair in the appropriate Tmax
seating on the new flange supplied with the
kit, after correctly inserting the O-ring seals.

h Make sure the IR filter glasses face
the right direction. The glasses have a
reference mark showing the side that
should face towards the outside of the
housing i.e. towards the direction from
which the IR radiation will arrive.
Position the front flange now fitted with the
IR filter glasses on the housing, making sure
the sealing rings are correctly inserted in their
seating so as not to damage them. Tighten the
4 screws using the allen wrench supplied.
The maximum working temperature of
these IR filter glasses is Tmax = 300°C.
The percentage of IR radiation filtered
by these IR filter glasses is 80%.
