Heaters
WARNING! Only qualified personnel should perform troubleshooting,
unqualified personnel may cause damage to the unit and put the operator
at risk. The Heaters are components that reach high temperatures; you
must wait until they cool before handling.
NOTE ! The Thermal Limit Switch is a safety switch in contact with the Heater
Body. If the surface temperature exceeds 220 F the Limit Switch will shut off
the Heater power. The Limit Switch will not re-set until the temperature in the
Heater is below 190 F. The system is designed that in case of an over
temperature a contactor located in the console will open disabling power to
both Heaters and the Hose.
Follow the recommended procedure in the indicated order to solve the problem and
avoid unnecessary repairs. Make sure all Switches are in the correct position and
Indicator Lights ON before determining the existence of a fault.
