Heaters
WARNING!
Before resolving any kind of defect, make sure all of the pushbuttons are
off, that the general switch is in shutdown position and that the unit is disconnected from
the power supply. Never handle the inside of the control panel with the unit connected to
the power supply. The heaters are components that reach high temperatures; wait until
they have cooled before handling.
NB:
The thermostat is a safety element
in contact with the heater. If the
temperature exceeds 120º C (248º F) the
thermostat will cut off the electric supply
by deactivating the POWER CONTROL.
The thermostat will not reset until the
temperature in the heater is below 120º
C (248º F).
If the temperature in the Isocyanate heater
or the Polyol heater is over 120º C (248º F),
an alarm will be activated and the
corresponding number will be shown on the
control panel (5 for Isocyanate and 6 for
Polyol).
Follow the recommended procedure in the
order indicated, to try to solve the problem
and avoid costly repairs. Make sure all the
automatic switches and control elements
are in the correct working position before
determining the existence of a fault.
