SMG8B & SSG8B

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. 

START UP

Follow the Dixell XR75 start up procedures as 
detailed on Page 3-1 of this manual. 

Each self contained merchandiser has its own 
evaporator coil and a pre-set thermostatic 
expansion valve (TEV). The TEV has been  
factory set at design conditions to provide the  
recommended performance.
