WARNING!
Use suitable protective gear and follow the safety recommendations of the
suppliers of the chemical components when preparing or working with the unit.
HI-TECH provides some accessories. This set comprises the following elements:
Tube of grease, magnet holder, parts manual and service manual.
NOTE:
To ensure the correct operation of the unit, the electrical power supply must
meet the specifications given on p
6
of this manual and on the unit’s rating plate.
The hoses have been subjected to a vacuum-drying treatment and are delivered with their ends
joined to prevent humidity from entering them. Do not separate them until the moment they are
to be fitted to the unit.
Proceed as follows to prepare the unit:
a) Remove the front protective covering from the pump guides
and fill the lube reservoir of the isocyanate pump with DOTP
plasticizer.
b) Connect the hose for each product to the outlet of its respective
heater (the isocyanate hose to the isocyanate heater and the
polyol hose to the polyol heater).
NOTE:
The hoses are colour-coded for easy identification: red for isocyanate and blue
for polyol.
To prevent connection errors, the isocyanate and polyol hose couplers are of
different sizes, which makes it impossible to connect a hose to the wrong heater.
