The sensor assembly is pushed to the bottom of the refrigerator as delivered from the
factory. If adjustments need to be made, the following procedure will simplify the
process.
•
Determine the range of the LN
2
level in the refrigerator (i.e. Start Fill = 9; Stop Fill
= 12)
•
Determine the appropriate offset by subtracting 2 from the Start Fill. (i.e. Offset =
9-2=7)
• Set the sensor assembly so that the very bottom of the assembly matches the
desired offset. This can be done as follows
-
Push down the sensor tube until it touches the bottom of the refrigerator.
- Mark the sensor wire where it emerges from the top of the sensor tube.
- Using the marked wire as a reference, pull the sensor up the same distance
as the offset setting. The sensor assembly is now in the correct location.
To make adjustments to a sensor assembly in a refrigerator filled with LN
2
, the
following procedure can be used:
•
Measure the LN
2
liquid level in the refrigerator.
• Take this measured level and subtract the offset to determine how many sensors
should be in liquid.
•
Go to “Test Level Sensor” through the Kryos menu (MENU, 2, 1). “L” means a
sensor is in liquid while “G” means a sensor is in gas.
• Move the sensor up or down so that the appropriate numbers of sensors are in
liquid (read “L”.)
•
Get back to the Kryos man screen and the level indicated should match the
physically measured reading.
The Sensor Offset, the Start Fill and the Stop Fill can all be set through the Kryos
menu system (MENU,2).
Removing/Installing the Solenoid Valve
Remove the controller using the procedures outlined for your particular refrigerator
model in the Removing/Installing the Controller section. Disconnect only the solenoid
valve lead connection from the controller board. Remove the back plumbing cover of
the refrigerator to gain access to the plumbing and solenoid valve.
To remove the solenoid valve loosen the compression fitting that connects the
plumbing tubing to fill tube. Unscrew the two (2) mounting screws that hold the
solenoid valve to the solenoid bracket. Then remove the solenoid valve and its
associated plumbing. Disconnect the plumbing from the inlet and outlet side of the
solenoid valve.
To install a new solenoid valve, attach the connecting plumbing to the inlet and outlet
connections of the valve using Teflon tape. Attach the compression fitting to the fill
tube first and then connect the compression fitting to the elbow that is connected to
the outlet side of the solenoid valve. Position the solenoid valve onto the solenoid
valve bracket and tighten the two (2) mounting screws. Attach the solenoid valve lead
NOTE:
After disconnecting the
solenoid valve leads do not
pull on wire. The wires are tied
and spiral wrapped together
