WARNING!
To prevent possible bodily harm caused by incorrect handling of the raw materials and
solvents used in the process, carefully read the safety information provided by your
supplier.
To avoid splashing open only one tank Isocyanate or Polyol.
Never change the chemical components, use always the same tank for each component.
In order to avoid product contamination, make sure that the tanks are well closed.
Do not fill the tank to its maximum capacity; check the level on the tank to make sure that
20% of its maximum capacity is vacant. Each tank is 30 liters.
Small vessels (10-15 liters maximum) are recommended to pour the product inside the
tanks.
Fill the tanks with the amount of product required for each application.
Before using the unit, the retained air and the residual oil from the operating tests made in the
factory must be eliminated. To purge the whole circuit, proceed as
follows:
a) Keep the coupling block with the outlet of each product in
separate vessels and open the manual valves of each
product.
b) Turn the pneumatic pressure regulator counter clockwise
as far as it will go.
c) Open the manual valves at the bottom of the tanks.
d) Turn the
“RETRATC” valve as it appears (in vertical
position it’s opened).
e) Turn the general switch
“ON”.
f) Push the
“START” green button. The temperature
regulator displays will light on, (whenever the switch of the
h
eaters is in “On“). Check the product pumps begin to
slowly move.
Allow the materials to come out of the coupling block until
the residual oil and the air bubbling has disappeared
completely.
g) Close the manual valves of each product and clean the
coupling block of the remaining supply of product.
h) Slowly increase the pneumatic pressure to check for
product leaks in the hose connections. Retighten if
necessary and tape the connectors to protect them from
possible damage.
i) Close the
“RETRACT” valve (horizontal position).
j) Turn the general switch
“OFF”. The temperature regulator
will go out.
k) Mount the gun on the coupling block.
