To change the nozzle, first remove the front cover then remove and replace the nozzle using a 10mm ring spanner,
sealing it with PTFE tape and ensuring that an angled nozzle is seated in the correct orientation. The Smoke Screen
is delivered with a single-hole straight nozzle and the following are also available – 2-hole horizontal, 3-hole
horizontal, 1-hole 30° angle down and 2-hole 30° angle down.
Be aware of high voltage
in the block area. The
electrical supply should be
switched off before
working in the heater block
compartment.
This operation is usually
carried out during
installation. If the Smoke
Screen has been in service
the nozzles will be
extremely hot and will
cause injury if touched.
Therefore, the Smoke
Screen should be switched
off and time should be
allowed for the nozzles to
cool.
