START-UP
• Check if the fans, on top of the furnace, are rotating and that the Excess
Temperature unit Power-on indicator is lighted. If one or more thermocouples are
not working, or one or more LED’s are lightning, refer to the section in the
maintenance chapter. Do not proceed further until conditions are corrected.
Note: If gascabinet, gassystem and loadstation are fitted, then power will be applied to
them, when the tube switches are turned on.
• Turn on the tube power switches, one by one. After turning each switch, ensure that:
• The tube indicator lamp is lighted.
• The temperature controller illuminates.
• The process controller illuminates.
• The touch panel illuminates (optional).
• If there are failures, see the Maintenance Chapter.
• Burn-in and oxidation of elements (see item 0)
4.3 Fast Cooldown
For a pliable movement of the valves, the pressure to close the valves in the manifolds needs
to be adjusted between 1 and 2 bar.
Note: More than 2 bar results in unnecessary high closing pressure.
WARNING
In case of unauthorized break of seal of the pressure
relief valve, Tempress Systems Inc. cannot accept any
responsibility in case of any damage on the system.
