Follow the recommended procedure, in the sequence given, to power-up the unit:
WARNING!
Do not start the power-up procedure described below until all necessary
prior adjustments have been made correctly.
a) Check the condition of the DOTP plasticizer contained in the isocyanate pump
’s lube
reservoir. Change the oil if it is discoloured or shows signs of solidification, and tighten
the packing nut to make the seal tight.
b) Make sure the product tanks are full or have the minimum content for application to
begin.
c) Check the product intake filters. Clean them if necessary.
d) Open the manual purge valves located under each tank.
e) Open the manual recirculation valves (hoses with recirculation).
NOTE:
Only perform this step if you wish to recirculate the products.
NOTE:
Recirculation of products enables heater temperature settings to be reached
quicker, heating both the hoses and the gun.
For more efficient heating during
recirculation, fill the tanks with the minimum amount of product necessary for the
application.
WARNING!
The product tanks are made of a plastic material which can withstand a
maximum temperature of 80ºC. The temperature of the products inside the tanks must
never exceed this limit.
WARNING!
Never recirculate when the tanks are completely full, as this can cause
abnormally high pressure in the tanks.
f) Check the hydraulic oil level. Add oil if the level is low.
g) Make sure the products are at the minimum required temperature for their delivery to
the unit via the transfer pumps. Contact your supplier for information on the minimum
delivery temperature.
h) Check the product intake filters. Clean them if necessary.
i) Rotate the power switch to the ON position. The upper pilot light goes on.
j) Press the CONTROL/POWER button. The LED will light up.
k) Press the button located under the HOSES/MANGUERAS display. The LED inside the
button will light up.
l) When the products contained in the hoses have reached working temperature, press
the ISO and RESIN buttons located under the HEATERS/CALENTADORES display.
Both LEDs will light up.
