Pressure Relief Procedure
Follow the Pressure Relief Procedure whenever
you see this symbol.
1. Turn main power switch OFF .
2. Close the inlet air supply ball valve.
NOTE: Manually verify the pressure is relieved by open-
ing the gun and ensuring no adhesive is dispensed.
Drain the System
NOTE: The system must be drained prior to flushing
and prior to some maintenance and repair procedures.
1. On the System 3 screen (in the Setup screens),
change the Refill Setting to “Manual”.
2. If the heating system is disabled, press to
enable the heaters and pump.
3. Decrease pump air pressure to 0.
4. Close system air inlet ball valve.
5. Disconnect hose from gun inlet then place hose out-
let in a waste container. Repeat for all hoses. Keep
hose to gun electrical connector connected.
6. Open gun to allow residual fluid in gun to drain.
7. When system is at operating temperature, slowly
increase pump air pressure until fluid begins flowing
into the waste container.
NOTE: It may take several minutes to empty the sys-
