2 Putting into operation
On delivery, immediately check if the machine is complete and if there are any
transportation damages. In the case of damages, please contact at once supplier or
forwarding agent.
2.1 Set-up directions
The machine should be placed on clean and dry ground. The ground should be even,
solid and level. The rear side of the machine must remain freely accessible to ensure
sufficient circulation of cooling air. The cooling air temperature must not exceed 35°C
and must not be contaminated. Only after all supply and connecting systems have been
connected, the machine may be put into operation.
2.2 Mains supply
Only trained personnel may connect the machine. Please pay attention to the nominal
voltage and frequency stated on the machine label. The voltage may /- 10%
(maximum) from the nominal value. The mains supply must at least be furnished with a
16 A delay-action fuse. All lines (L1, L2, L3 and PE) must be connected correctly
2.3 Cooling water
Use two hoses with an inner ø of 8 mm for the cooling water. The water entry pressure
must be at least 2.5 bars and must not be more than 5 bars. The water drainage must
be without pressure. The water entry temperature must be above 15 °C and must not
exceed 25 °C. The concentration of lime in the water must not be more than 60 mg
CaO/l. The cooling water must not be contaminated.
The supply hose for the granulating apparatus (option) must have an inner ø of 8 mm
also, the draining hose an inner diameter of 19 mm.
Caution: As long as the crucible temperature is above 100 °C, the cooling water supply
must be open; otherwise the inductor insulation could be destroyed. In case the cooling
water supply stops while there is still a hot crucible inside the machine, the crucible
must be removed at once.
