CAUTION!
The unit includes components that reach temperature that are liable to
cause burns. The hot parts of the unit must not be handled until they have cooled.
When you plan to shut down the machine for more than five weeks, the products contained in
the machine must be replaced by DOTP plasticizing agent.
Follow the recommended procedures in the order indicated:
a) Place two drums of DOTP cleaning agent close to the machine.
b) Dismantle the gun and leave the coupling block connected to the hoses.
c) Place 2 separate vessels under the coupling block to gather up the products contained
inside the machine.
d) Open the manual valves on the coupling block.
e) Open the manual valves at the bottom of the tanks.
f) Open the
“RETRACT” valve (vertical position).
g) Turn the general switch
“ON”. Using the air pressure regulators, turn anti-clockwise until
the end.
h) Push the
“START” green button, the temperature regulator will light on, (whenever the
switch of the heaters is in “On“). Check the product pumps begin to slowly move.
If necessary, increase the pneumatic pressure by turning the regulator clockwise.
i) Allow the materials to come out of the coupling block until the tanks are empty.
j) Turn the general switch
“OFF”. The temperature regulator will go out.
k) Close the manual valves at the bottom of the tanks.
l) Fill the component tanks using DOTP cleaning agent, about 5 liters each one.
m) Open the manual valves at the bottom of the tanks.
n) Turn the general switch
“ON”.
o) Push the
“START” green button, the temperature regulator will light on, (whenever the
switch of the heaters is in “On“). Check the product pumps begin to slowly move.
p) Turn the general switch
“OFF”. The temperature regulator will go out.
q) Close the
“RETRATC” valve (horizontal position).
CAUTION!
To avoid possible product leakage and the 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.
The proportioning pumps, the heaters and the hoses must be full of DOTP plasticizing
oil. Never leave the machine or the hoses empty of product or DOTP plasticizing oil.
