Filling the Refrigerator (Initial Fill)
The 10K and 24K units using the KRYOS controller come preset from the factory to
operate. For the 38K unit, refer to the Installing the Controller section in this
manual.
The liquid nitrogen supply pressure at the inlet to the refrigerator should be in the
range of 10 psig (0.7 bar/69 kPa) to 20 psig (1.4 bar/138 kPa) for optimum perfor-
mance. Higher operating pressures will increase transfer losses and create
excessive turbulence of the liquid in the refrigerator which can generate false
signals to the liquid level controller causing the refrigerator to underfill. In “liquid
phase” storage applications, excessive turbulence can cause splashing which
could result in personal injury and/or damage to the refrigerator.
WARNING: Maintain adequate ventilation to prevent asphyxiation hazard
(see Safety Precautions)
Power Supply Connection
Connect the 24 Volt AC power supply to the rear of the cryostorage system; then
plug the power supply into a surge protected 110/120 VAC outlet.
WARNING: If the fill fails to stop for any reason, quickly close the liquid supply
valve to prevent overfilling until the cause of the problem can be
determined.
Thank you for purchasing this product. This state of the art CRYOSTORAGE SYS-
TEM can control either the liquid level and/or the vapor temperature range. The
features are designed to provide a safe environment for samples while at the same
time tracking all relevant information associated with the freezer. This control pro-
vides a complete historical record of the environment in your freezer and therefore,
the environment in which your samples have been stored.
CONTROL COMPONENTS
Interface Panel
The KRYOS Interface panel, which the user will interact with, contains the vacuum
fluorescent display as well as the number keypad, power button, help button and the
soft-key control buttons.
