CAUTION!
Use suitable protection and follow the recommendations in the safety
information provided by product suppliers when installing or working with the unit.
NOTE:
To ensure that the unit works correctly, the electrical supply must meet the
specifications indicated on page six of this manual and appearing on the machine
specifications plate.
Follow the recommended procedure in the indicated order to
install the unit:
a) Fill the Isocyanate pump lubricating cup with DOTP
plasticizer.
b) Connect the pressure hose of each product to the
outlet of the respective heaters (the Isocyanate hose to
the Isocyanate heater and the Polyol hose to the
Polyol heater).
c) Connect the recirculation hose of each product to the
recirculation valves located in the ISO or POLY tank.
(the Isocyanate hose to the Isocyanate tank valve and
the same in the Polyol side).
NOTE:
The product hoses have been identified with red (Isocyanate) and blue (Polyol),
enabling them to be rapidly distinguished. To avoid errors in connecting the coupling
connectors of the Isocyanate and Polyol hoses, the connectors are of different sizes to
make it impossible for connections to be swapped.

Method of union of the Hoses
WARNING!
To join the hoses together or to connect them to the heaters or the gun,
use two spanners to hold the parts to be joined (1) and a third spanner to tighten or
loosen the connecting nut (2) as shown in the illustrations in Figure 3 on page 16. The
connections must be tightened to a torque of 20 Nm.
