2 Safety advice
This furnace may only be operated with the supplied mains power lead!
Prior to making the electrical connection, make sure that
- the furnace power switch is OFF.
- the furnace voltage matches your power supply. Confirm the line voltage for your furnace by checking the
line voltage designation on the rating plate on the back of furnace.
- the protection fuse and the wiring system in your laboratory are suitable to carry the total electric load of
the furnace (see rating plate and/or technical specifications).
- the wiring system in your laboratory has an efficient earth connection in compliance with rules and laws in
force.
- the plug is inserted into a suitable wall socket which can easily be reached.
- the mains power lead is laid out in such way as to ensure that it does not come into contact with any hot
surfaces or objects and that it does not obstruct any passage way.
!The manufacturer disclaims any liability in case these accident-preventing rules are not observed !
This is a warning symbol about dangerous electrical current. Disconnect furnace
from the mains power supply before opening it for maintenance or repair work.
Contact your VITA dealer or a qualified service technician if your furnace needs
to be repaired or serviced.
Typ PJ 9080-023.3
or This label gives information on the power connection of the vacuum pump.
Typ PJ 9081-023.3
It is not necessary to clean the inside of the firing chamber, but only to wipe the
surface of the insulation at the lower edge of the firing chamber regularly with a
damp cloth. This applies also to the O-ring on the lift support plate.The casing
can likewise be cleaned using a damp cloth. In order to ensure smooth gliding of
the firing tray lift at all times, the lift guide rails should be wiped regularly with a
dry cloth.
Never use cleaning agents or flammable liquids for cleaning the furnace
3 Installation and Starting-Up
(see also Safety Advice)
1. When positioning the furnace, the minimum distance between all sides of the furnace and any wall
should be at least 25 cm.
2. Make sure the furnace power switch is OFF. Connect the furnace to the mains outlet, using the supplied
mains power lead.
3. Connect the plug of the vacuum pump to the socket at the rear of the furnace and then slide the vacuum
hose onto the nozzle.
4. Attach the operating panel to the front of the casing and connect the spiral cable to the right or left side.
5. Press the Power ON/OFF switch at the left to switch on the fuirnace. The firing tray lift will descendto ist
lower position. The LCD indicators in Block A display the current firing chamber temperature and the time
of day.
6. Place the firing tray onto the lift support plate.
Notice: Never operate the VITA VACUMAT 500 without the firing tray on the lift support plate. It may
cause damage to the furnace.
7. Press the "Start" key. The firing tray ascends into the firing chamber, and the temperature starts
risinguntil it has reached the factory-set starting temperature of 500°C.
Once the starting temperature has been reached, the furnace is ready for use with any firing program.
For further operating information, see the appropriate section of the Operating Manual.
