Genevac HT-4X Evaporation System

To start the system, press the green

START

button on the evaporator keypad.

The vacuum pump starts and the

SELECT RUN

menu appears on the

evaporator LCD screen.

The condenser also powers up and begins to cool down to its operating temperature. The
system will not allow an evaporation run to commence until the condenser reaches 0°C; if an
attempt is made to start, the run will commence once operational temperature has been
reached.

Note:

For HCl systems, an additional pump warm-up sequence must complete before the

system will allow an evaporation run to commence (this prevents the possibility of solvent
condensation inside the pump). The warm-up time remaining is shown on the screen.

To power down, enter the

Select Run

screen and press the

STOP

key. Press Y on the

evaporator keypad when prompted:

Note:

If a pump purge sequence begins, allow this to finish before switching off the

evaporator power switch.
