Original instructions
7.
Open the fluid circulation valve by completely “down-seating” (turn top
valve stem completely clockwise) to direct fluid to by-pass through tubing
to fluid reservoir.
8.
Temporarily re-install the left cover and secure it to the base plate with (3)
hex head screw. Attach the power wires to the power switch. Turn the
power switch ON, and start the Stoppering Tray Dryer in Manual mode
with Shelf Temp Set Point at 24°C (75°F). The fluid system will circulate
with the fluid going through the by-pass tubing, purging itself of air. Add
fluid as needed to keep fluid in the reservoir. Allow the fluid to circulate
until no air bubbles are seen coming through the by-pass tubing.
9.
After the system is free of air, “up-seat” fluid circulation valve (turn valve
stem completely counter-clockwise, closing the fluid/tubing by-pass).
10.
When the system temperature stabilizes, add or remove fluid from the
reservoir to the level indicated by the label.
11.
Apply vacuum to the unit, and when the system is 0.133 mbar or less,
install the cap on the tank.
12.
Remove the tubing. Replace the caps on the valve and replace insulation
and covers.
