Vinotemp WINE-MATE VINO-1500SSL, Installation & Operation Manual

- 13 -

7. 

Use of the encapsulated pressure control (if applicable)

Fixed suction pressure setting: Cut in = 32 psig; Cut out = 10 psig 
 

Fig. 13 Fixed Pressure Control 

8. 

Use of the condenser fan control (if applicable for low ambient kit)

Head pressure setting: Cut in=170 psig; Cut out=120 psig; Differential=50 psig 

It closes on rise of pressure. It may need to adjust the setting in the field to avoid 
fan short cycle. 

9. 

Use of the crankcase heater (if applicable for low ambient kit)

The crankcase heater is installed around the lower part of the compressor and 
shall be turned on all the time.  The heater is self-regulated. 
 

10. Pressure, Superheat and Subcooling Readings 

CAUTION:  
THE VALVES MUST BE IN THE MIDDLE POSITIONS TO READ PROPERLY.
