Installation
Note:
Do not apply power to the Controller or connect an LN
2
supply until later in this procedure to avoid injury or damaging
the equipment.
Following the careful uncrating and unpacking of the freezer,
install using these basic instructions.
•
Locate the temperature sensor tube assembly that will
house the two temperature probes. A three-tube
temperature sensor assembly will be installed in the
center of the top of the freezer. The two smaller tubes are
designed to house the included temperature probes. The
third, larger tube is designed to accommodate a third-
party temperature probe. A silicone plug will be installed
in this third tube. If the third tube is going to be used,
simply remove the silicone plug.
•
Insert the two temperature probes into the sensor tubes
and position the sensors at the preferred height in the
freezer space. Selecting probe A and B as well as the
sensor placement is adjustable and completely up to the
user. Thermo Fisher Scientific does recommend placing
sensor (Temp A) at the “top box” level. This refers to the
level in the freezer space where the highest sample is
being stored. If storing vials in boxes, then this would be
at the level with the top box. This is recommended as it
will be the warmest temperature experience by samples
being stored in the freezer space.
•
Connect the temperature probes to the Controller
temperature ports using the twist lock connectors.
•
For CryoExtra
models, once the temperature probes are
in the desired position, apply a small amount of the
silicone sealant, included with the freezer, surrounding
the temperature probes where they enter the sensor
tubes. This will help maintain their position and help keep
moisture from entering the freezer storage space.
Proceed to the next step.
•
Connect the clear vinyl tubing to the Controller Level
Input hose barb and connect the other end of the tubing
to the 3 way purge valve.
•
Ensure all of the plumbing assembly connections to the
Controller wire harness are secure.
Note:
Do not connect the battery backup (if equipped) to the
wire harness until later in the installation procedure.
CAUTION :
Only install the freezer on a level
surface. Never fill freezer and move to another
location. Always fill the freezer where it is to be
installed/used.
