Follow the recommended procedure in the indicated order for machine shut down when work is
stopped for the day.
a) Close the
“RETRACT” valve, (horizontal position).
b) Close the manual valves at the bottom of the tanks.
c) Use the gun to project into a waste container until the Isocyanate proportioning pump is
in the retract position and the pressure begins to fall.
CAUTION!
To avoid possible product leakage and early failure of the pump seals, the
pressure must not be reduced to zero. It is recommended to keep the system with a
minimum pressure of 30 bar (400 psi) to extend the life of the seals.
d) Turn the general switch
“OFF”. The temperature regulator displays will then go out.
e) Close the manual valves on the coupling block and dismantle the gun to perform the
corresponding maintenance.
