Warm Up (Without Film Loaded) - usi CRL 40 Instruction Manual

6. WARM-UP (Without film)
(Refer to page 15 for warm up with film loaded).
(a) Connect machine to a single phase power source.
(b) Check that the Forward/Reverse control is in the OFF position.
(c) Switch 'ON' main power switch.
(d) The red "power" light should glow.
Dial the thermostat (heater) knob to 270 o F.
(e)
(f) Providing there is no excessive adhesive residue on the roller (see i below) the rollers may be
rotated after 10 minutes warm-up.
(g) To ensure elimination of cold spot (refer page 16) the rollers should be allowed to rotate for a
further 10 minutes.
(h) Reduce the temperature to 250° - 270°F, the normal laminating temperature.
The machine is now ready to load film
Full warm-up time usually takes 20-25 minutes depending on the climatic conditions. While the heat shoes
may reach operating temperature quite quickly (indicated by red light) good lamination requires evenly
heated rubber surfaces on the nip rollers and these take longer to warm-up. Patience and good roller rotation
will ensure an even heat soak of the rollers giving optimum laminating results.
In normal circumstances temperature setpoint is all that will need to be changed.
