MiniVap Over Temperature Thermal Cut-out

Please note that the MiniVap instruments supplied after November 2013 are fitted with a repositioned
thermal cut out switch. If the heater goes above a pre-set safe temperature, the thermal cut out will
activate and the heater will be switched off. Once the heater cools down again the cut out will
automatically reset itself, and power will be restored to the heaters.

If this occurs frequently, please contact Porvair Sciences immediately as it could indicate a fault.
