CAUTION!
The unit includes components that reach temperatures that are liable to
cause burns. The hot parts of the unit must not be handled until they have cooled.
To avoid possible contamination, the circuits of the unit must be flushed clean (pumps, heaters
and hoses) whenever applications have to be made that require a change of components.
Follow the recommended procedures in the order indicated to perform the cleaning:
a) Remove the recirculation hoses and place them in two separate vessels to gather up
the products contained inside the machine.
NOTE:
Should the products be used again, use a proper vessel to store them, following
the instructions from your product supplier.
b) Open the manual valves at the bottom of the tanks.
c) Open the manual recirculation valves.
d) Open the
“RETRACT” valve, (vertical position).
e) Turn the general switch
“ON”.
f) Turn the air pressure regulator anti-clockwise until the end.
g) Push the
“START” green button. The temperature regulator displays will light on,
(whenever the switch of the heaters is in “On“). Check the product pumps begin to
move slowly.
If necessary, increase the pneumatic pressure by turning the regulator clockwise until
the product pumps begin to move slowly.
h) Allow the materials to come out of the recirculation hose until the tanks are completely
empty.
i) Turn the general switch
“OFF”. The temperature regulator displays will then go out.
j) Close the product manual valves at the bottom of the tanks.
k) Fill the component tanks using DOTP cleaning agent (about 5 liters in each tank).
l) Open the product manual valves at the bottom of the tanks.
m) Place the recirculation hoses to their tanks again and make sure the recirculation valves
are open.
n) Dismantle the gun and leave the coupling block connected to the hoses. Make sure the
gun valves are closed.
o) Turn the general switch
“ON”.
p) Push the
“START” button. The temperature regulator displays will light on, (whenever
the switch of the heaters is in “On“). Check that the product pumps move.
q) Maintain the unit recirculating for about 2-3 minutes to clean the hoses and the tanks.
For a more efficient cleaning of the tanks, the cleaning agent can be heated through the
heaters.
r) Turn the general switch
“OFF”. The temperature regulator displays will then go out.
s) Remove the recirculation hoses of the Isocyanate and Polyol tanks again and place
them in two separate waste vessels.
