3. Setting into operation
3.1 Safety specifications
Be aware of the hot coolant. Ensure, that the coolant temperature is low before opening any connections.
3.2 Preparation before first Start-up
Perform the following steps:
1) visual inspection of the device and hose on tightness
2) check the level of the coolant. It must not be less than the “COLD LEVEL”
3) adjust the flow meter to 1,5 m 3 /h minimum flow
4) open the stop valve (14) entirely
5) set the main switch into the “ON” position
6) press S1 to start the circulation pump
7) adjust the coolant flow by means of the stop valve (14) to 3,6m 3 /h
8) Open the bleed valve (16) for short time so that air can escape from the expansion
vessel
9) observe the coolant through the inspection glass to ensure that no bubbles are in the
coolant
10) Insert the probe to the kiln
11) observe the increase of the coolant temperature
12) at a coolant temperature of 180°C the fan should be switched on
13) at 180°C check the coolant level in the expansion vessel
14) in case of too high “COLD LEVEL” the coolant escapes through the check valves
