2.5 NOZZLE CHANGING
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 plus an extra 1-hole 30 deg angle down nozzle. 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.
