Follow the recommended procedure in the indicated order.
CAUTION!
The start-up procedure assumes that all of the necessary adjustments have
been correctly performed.
a) Check the state of the DOTP plasticizer in the Isocyanate pump lubrication cup.
Change the oil if you see changes in the color or signs of solidification and retighten the
packing nut to ensure the seal.
b) Make sure the level of the chemical tanks is enough to process the system.
c) Check the inlet filters of the products. Clean them if necessary.
d) Open the manual valves at the bottom of the tanks.
e) Turn the potentiometer located on the transformer to apply the electrical intensity to the
heating hose system. (
See Amps table on page 12
Selected intensity must not be maintained over 10 minutes. After that
time, turn the potentiometer anti-clockwise until the screen shows
25amps.
To avoid excessive pressure in the heated hoses, wait for the product in
them to reach the required temperature before starting up the air motor
system.
f) Turn the general switch
“ON”.
g) Open the
“RETRATC” valve (vertical position).
h) Push the
“START” green button, the temperature regulator displays will light on,
(whenever the switch of the heaters is in “On“).
i) Set the Isocyanate Temperature on the Iso Regulator.
j) Set the Polyol Temperature on the Poly Regulator.
k) Using the air pressure regulators, first of all select the pressure for the down stroke of
the proportioning pumps and then adjust the pressure for the up stroke. The pressures
must be practically the same and remain constant. If the pressures fluctuate on each
stroke, consult the fault section before continuing.
l) Connect the air supply to the gun; open the manual valves of each product; make a test
projection and check the pressures on the product gages. If the projection test is correct
and the pressures remain equal, proceed with the application
