1. The Dixell XR75 Controller controls
refrigeration temperature. This is factory
installed in the control panel. Measure
discharge air temperatures at the center of the
honeycomb.
For low temperature models, defrosts are
time initiated and temperature terminated.
The defrost setting is factory set as shown. To
ensure a thorough defrost, the defrost must
be terminated by the temperature termination
setting — not by time. For medium
temperature models, defrost is time initiated
and temperature terminated.
