STARTING UP
After setup and installation, proceed as follows to start up:
Instruction Button / Remarks Display / Remarks / State
Check start-up status
Check the Input pressure of the
process gas, open the oven
door Observe the pressure reducer
for the inert-gas supply (gas
bottle), open the fine metering
valve (Fig. 3/2), let the gas flow
out Pressure reducer - 1 bar Input
pressure, close the fine meter-
ing valve
Check the input pressure of the
emergency inert-gas supply Observe the pressure reducer
for the emergency inert-gas
supply (gas bottle), open the
manual shut-off valve (Fig. 3/2,
item 1), let the gas flow out Pressure reducer - 2 bar input
pressure, close the manual
shut-off valve

operating temperature TWB scale - cut-out temperature
(at least approx. 20 °C above
operating temperature)
Select the temperature control-
ler to the required operating
temperature Temperature controller (Fig.
3/2), the minimum operating
temperature must be 10 °C
above room temperature. Display the required tempera-

use
Open the vacuum shut-off valve Vacuum pump extracts the at-
mosphere from the chamber Pressure indicator (Fig. 3/2), the
heating system is enabled when
the pressure drops below
approx. 35 mbar, within 1000
mbar ambient pressure, white
indicator lamp is lighting.. The
oven warms up -process starts
