5)
Check that the water curtain moves freely.
6)
Verify that the nozzles send water to the evaporator in the correct direction (uniform fans).
7)
After 10 minutes, check that the water bin has no leaks on the maximum level overflow.

6. ADJUSTMENTS
6.1.
Condenser water pressure valve
-
This pressure switch controls high pressure by opening and closing the condenser water
valve.
Differential is a fixed 1 Bar (14 psi.).
-
The valve closes at 15 Bar (214 psi), which is equivalent to a condensation water exit
temperature of 38ºC (100ºF). . Below this pressure it will be difficult to unstick the cubes
during the
defrosting cycle.
-
Above this pressure, compressor life and ice production are both reduced.
Pressure can be increased by turning the small screw on the pressure switch clockwise. A full
turn is
equivalent to about 1.5 Bar.
6.2.
Fan pressure switch (air–cooled models)
Pressure Control operates on high pressure by starting and stopping fan. Differential is a fixed
(1 Bar or 14 psi.).
Cut-off pressure must be 15 Bar (214 psi). Low pressure values may cause difficulties during
harvest cycle. Higher pressure values may shorten compressor life and diminish ice production.
Pressure can be regulated by rotating screw on Pressure Control Valve (clockwise to increase
pressure). One full turn is equivalent to about 1.5 Bar.
