KRYOS
Fill Solenoid Cycles On and Off
KRYOS features a Freeze-Guard function whereby the valve open duration is limited,
allowed to shut for a short warm-up and then opened again. To confirm or change
the valve open duration:
t Select MENU, USER OPTIONS, CONTROL OPTIONS, FREEZE-GUARD
OPTIONS, VALVE OPEN DURATION.
If the controller detects that the valve is stuck in the open position (i.e., continues to
fill after the valve is de-energized), it will attempt to De-Ice the valve by causing a
rapid cycling of the valve in an attempt to dislodge the blockage.
t To activate or de-activate this feature: Select MENU, USER OPTIONS,
CONTROL OPTIONS, FREEZE-GUARD OPTIONS, VALVE DE-ICING.
Repeated cycling of the Solenoid Valve, excessive turbulence or a low battery could
be attributable to moisture invasion on the controller circuit board.
1. Check gasket seals.
2. Access control board and allow time to fully dry.
3. Check the 3-prong plug is connected. Check the battery connection to the
controller and to the wall. Check the charge on the battery.
4. Confirm the pressure of the supply vessel is less than 22 psi.
5. Watch the interface panel on the controller to verify if the Start and Stop Fill
cycles are repeating.
Fill Solenoid Makes Humming Noise
Turn fill valve on and off using the control panel. If humming continues, it should
continue to operate reliably. If the noise is excessive, replace solenoid valve.
Transformer Makes Humming Noise
This noise is a normal byproduct of most block transformers. The transformer has
a non-renewable internal fuse to protect the transformer output. If the noise is
excessive, replace the transformer.
Display = “Check”
The word CHECK will flash during periods of Splash-Guard protection. See page 29
for more information.
Lid Open Alarm
A lid switch is located on the front hinge. The proximity switch should actuate when
the hinge is opened and again when it is shut.
t Confirm that there is a ½” (12 mm) gap between the sensors.”
QCF (Quick Chill Feature) Will Not Operate

To activate or adjust times: Select MENU, USER OPTIONS, CONTROL OPTIONS,
LID/DEFOG SETTINGS, QUICK CHILL.
