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) Attach the power wires to the power switch. Activate the pump by
moving the Power switch to the ON position. The control panel does not
need to be installed. If it is installed, the RUN/STOP switch must be off.
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 stoppering system
up and down. Observe the fluid stream and repeat the tilt procedure if it is
not free of bubbles.
(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)
Set the controller to operate at 24°C (75°F) in the manual mode. Push the
“Run/Stop” switch to start the system.
(11)
When the system temperature stabilizes, add or remove fluid from the
reservoir to the level indicated by the label.
(12)
Apply vacuum to the unit, and when the system is
0.133 mBar or less install the cap on the tank.
(13)
Remove the tubing. Replace the caps on the valve and replace insulation
and covers.
