8. Connect the unit to the proper power source. Activate the pump from the
display screen (Home screen) by selecting MANUAL, entering 24°C (in
Shelf Temp Set Point entry field), and pressing Start. This will start the
heat transfer fluid pump and also the refrigeration system. The fluid
system will circulate with the fluid going through the add-on tubing,
purging itself of air. Add fluid when needed to keep fluid in the reservoir.
After the fluid stream is established, tilt the entire freeze dry system up
and down. Observe the fluid stream and repeat the tilt procedure if it is
not free of bubbles. Fill reservoir to level indicated by the label.
9. Turn the pump and refrigeration system OFF by pressing MANUAL, then
Stop. Disconnect power cord from supply outlet.
10. Close “up-seat” fluid circulation valve (turn valve stem completely
counter-clockwise, closing the fluid/tubing by-pass).
11. Remove the tubing. Replace the caps on the valve and replace insulation
and covers. Replace the cap on the tank.
12. Replace insulation and seal air tight. Replace rear cover.
