Operation Shutting Down
6.4 Pressure Relief Procedure
Perform the Pressure Relief Procedure when
shutting down for any reason.
1. Engage the trigger safety (refer to the spray gun instruction
manual).
2. Close the manifold valves A and B on the spray gun.
3. Performallofthesestepsonbothcomponentpumps:
a. Turn the pressure control knob fully counterclockwise to
minimum.
b. Turn the PRIME/SPRAY knob to PRIME.
4. Disconnect the spray gun air supply line.
6.3 Spraying
Refer to the safety information in the beginning of
this manual for injury prevention guidelines. Refer
to the safety and operation instructions of the gun
manual.
1. Engage the trigger safety (refer to the spray gun instruction
manual).
2. Make sure the valves A / B on the coupling block are closed.
3. Reattach the coupling block (with hoses attached) to the spray
gun.
4. Connect the end of the air hose that is closest to the pump
to an air supply (the air hose is housed within the velco
sheathing that also contains the dual heated hoses). Connect
the other end of the air hose to the spray gun. Make sure the
air valve on the air hose (if any) is open.
5. Make sure the PRIME/SPRAY valves on the component pumps
are set to SPRAY.
6. Verifythatthetemperaturereadingsareshowingthedesired
temperatures.
7. Verifypressurereadings:
a. Check pressure gauges mounted on the front of the system, or
b. For each component pump, go to the Control Display Main
Screen on the control panel.
i
The pressures shown on either the gauges or the
Control Display Screens should be within 200 PSI. If
pressure is unbalanced, unlink the pumps, and then
adjust the pressure to desired balanced pressure.
Once pressure is balanced, re-link the pumps.
8. Open the coupling block valves A and B on the spray gun.
NEVER open the manifold valves on the coupling
block or trigger the spray gun if the pressure
readings are unbalanced.
9. Disengage the trigger safety (refer to the spray gun instruction
manual).
10. Test your spray on a piece of scrap wood or cardboard. Adjust
pressure and temperatures as necessary to achieve desired
results.
Attention
Always close the manifold valves if the system is idle
for more than 1 minute under heat and/or pressure.
Failure to do so can cause a pressure imbalance
which can then lead to a material “crossover” inside
the gun, leaving the gun inoperable.
Make sure the Component Pump pressures are
balanced prior to opening the manifold valves and
resuming spraying.
