WARNING!
Use suitable protective gear and follow the safety recommendations of the
suppliers of the chemical components when preparing or working with the unit.
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.
After following steps a), b), c) and d) of the preparation procedure (see
p.18), follow the procedure given below to prepare the unit to work with
heated hoses:
a) Connect the hose heating temperature control cable to the
connector on the side of the electric cabinet.
WARNING!
To join hoses to each other, to the heaters, or to the
gun, hold each hose end in place with a spanner (1), and with a
third spanner tighten or loosen the coupling nut (2) as required
(see Figure 3 on p. 17

.
These couplers should be tightened to a
torque of 20 Nm.
NOTE:
To prevent product leakage and avoid heating system malfunction, make sure
the hoses are correctly connected, electrically and mechanically.
b)
Connect the air hose to the unit’s power socket and to the gun.
c)
Connect the 60 cm whip hose to the gun’s coupling block connectors, making sure the
manual valves are closed.
d) Fit the temperature control sensor, with its extension nozzle, between the heated hose
and the whip hose connected to the gun. Carefully insert the sensor cable into the
heated isocyanate hose.
NOTE:
Once fitted with a temperature control sensor, hoses should be handled with
care and should not be folded to excess.
When coiling the hoses, make sure the winding
radius is at least one metre.
