Clean air environment
The projector and the external cooler must always be mounted in a manner which ensures the free flow of
clean air into the air inlets. For installations in environments where the projector is subject to airborne
contaminants such as that produced by smoke machines or similar devices (these deposit a thin layer of
greasy residue upon the projectors internal optics and imaging electronic surfaces, degrading performance), it
is highly advisable and desirable to have this contamination removed prior to it reaching the air inlets. Devices
or structures to extract or shield contaminated air well away from the projector and cooler are a prerequisite, if
this is not a feasible solution then measures to relocate the projector and cooler to a clean air environment
should be considered.
An air filter for a singular cooler module is not delivered by default, since it is not possible to mount a filter on a
singular loose unit without use of external options (e.g. the rigging frame). However, it is still advised to use an
air filter alongside the cooler module. Barco provides a kit with the filter commonly used in combination with
this type of cooler module (
R9801562
).
Air flow requirements
The cooler module is fan cooled and must be installed with sufficient space around the air inlets and outlets.
Make sure a space of minimum 15 cm (6 in) is available to ensure sufficient air flow. It should be used in an
area where the ambient temperature, as measured at the air inlets, does not exceed 40 °C (104 °F). Also take
into account the airflow coming out of the cooler (225 CFM).
If the Barco filter is used, keep in account that the distance between filter and air inlets should still
be around 5 cm (2 in). Distance between filter and the solid surface then should be around 10cm (4
in).

For this reason, if you use one or more cooler modules without any mounting support or rigging frame, it is not
allowed to place a single cooler module on the ground in normal position. In this case, the cooler should be
placed either facing upwards, or on its side (with the tubes going to the left).
