APPLICATIONS
Closing with rising temperature and possibility to manually
initiate a defrost function is achieved by pressing the defrost
pin (stroke approximate .157 (4mm)) until latching. By doing
this, the main switch is opened and locked until the defrost
temperature is reached at the sensing point of the capillary
which is normally fixed at the evaporator. After the defrost
temperature has been reached, the pressure pin returns to
its OFF position and the normal ON/OFF operation of the
temperature control is reset. Defrost function can be initiated
in any position of the dial shaft. If initiated in error, the defrost
function can be cancelled by turning the dial shaft to the OFF
position.
