CONNECTING POWER
The CryoWiz™ is supplied with a universal power supply that includes a variety of snap-in international plugs and
works with 90 – 264 VAC. The output is 12 VDC, 1.50 amps, 18 watts max.. It is strongly recommended that a
battery backup such as a UPS be used to ensure the continuous function of the device.

STARTUP
The initial startup of the CryoWiz™ should always be performed by a CONCOA factory-trained service technician
with the area oxygen deficiency monitors functional and enabled. Use proper safety equipment including but not
limited to full face shields and cryogenic gloves and aprons as certain steps do require that LN2 be introduced
into the system. Proper safety procedures must be maintained at all times when handling LN2.
Once all mechanical connections are made, both on the CryoWiz™ and on any downstream equipment,
pressurize the system and check for leaks.
Ensure that as described in the “Installing the CryoWiz™” section that the system has been connected to a 95 to
110 PSIG pneumatic dry nitrogen supply.
All connections downstream of the system must be connected prior to connecting electrical power and starting up
the system. Test for leaks with an appropriate liquid leak test solution. If leaks are discovered, remake
connections and recheck.
The CryoWiz™ will start up in the ON DEMAND mode with the left side selected as primary. If desired, use the
SOURCE select pushbutton to switch sides. The primary source valve will open and fill the downstream outlet
until pressure has equalized. Check for leaks downstream with an appropriate liquid leak test solution. If the
system continues to fill with no real demand for liquid downstream, this is an indication of a leak. Turn off power
to the unit, and check all connections.
Normal operation of the CryoWiz™ can now begin. All switching is automatic.
