Exhaust System Cleaning Switch
Exhaust System Cleaning Enabled
The switch remains in the standard
mid-position
during normal
operations. This means Exhaust System Cleaning is enabled and allows
the exhaust system to clear any build-up by initiating automatic cleaning.
Exhaust System Cleaning initiated automatically by a preset timer at 20-
hour intervals and takes around 15-30 minutes to complete. No operator
action is required and the equipment continues to work as normal during
the cleaning.
The HEST lamp may illuminate during cleaning to indicate higher than normal exhaust temperatures and
safety considerations apply.
Start Exhaust System Cleaning
Pressing the switch into the
top position
starts a manual (parked)
Exhaust System Cleaning. This is required on infrequent occasions
due to very unusual duty cycle conditions. A manual (parked)
Exhaust System Cleaning may be needed when the Exhaust
System Cleaning Lamp illuminates. When the Start Switch is
pressed, cleaning begins and this is confirmed by the Exhaust
System
Cleaning
Lamp
flashing.
The HEST lamp may illuminate during the manual (parked) Exhaust
System Cleaning to indicate higher than normal exhaust
temperatures and safety considerations apply. The switch returns
to the standard Mid-Position after pressing the manual (parked)
Exhaust System cleaning.
Stop Exhaust System Cleaning Function
Pressing the switch into the
bottom position
prevents Exhaust
System Cleaning from occurring. Stopping the Exhaust System
Cleaning function is required only for safety reasons to avoid higher
than normal exhaust temperatures.
When the switch is pressed the Exhaust System Cleaning STOP
Lamp illuminates to indicate Exhaust System Cleaning is disabled.
The switch remains engaged in this position until pressed back to
the standard mid-position to restore the automatic Exhaust System
Cleaning function.
Exhaust System Cleaning should not be left disabled for long
periods of time as this results in the need for a manual (parked)
Exhaust System Cleaning.
