7.3 Starting up the indicator when the boiler is under pressure and
Temperature stands
The shut-off valves (A1, B1) must be closed and the drain valve (18) must
be fully open. Next, slowly and carefully open the upper stop valve (A1) a
little so that the glass (TG32) or or mica (TG120) is carefully heated. Then
the upper stop valve closes again. Now the upper stop valve (A1) can
be opened slowly until it stops. Next the lower stop valve (B1) must be
opened slightly (approx.: 5-minute position) so that the ball in the valve cannot block
the valve passage. After pressure compensation, open the lower stop valve (B1) as far
as it will go. Wait for the water level to be adjusted and then check the indicator for
leakage. After commissioning the indicator must be checked for function and leakage.
The specified torques and the described tightening sequence (point 7.1) apply.
7.4 Maintenance
When replacing components, it must be ensured that only original IGEMA GmbH parts
are used.
Any warranty is void if components from other manufacturers are used.
7.5 Cleaning the indicator
Close top and bottom shutoff valves (A1, B1).
Open drain valve (18), unit will empty; this normally signifies that
cleaning is completed.
Put the device into operation as described under Chapter 8.
If cleaning was not sufficient:
•
Close top and bottom shutoff devices (A1, B1).
•
Open drain valve (18), then slowly open top shutoff device (A1); the steam flowing through
the unit cleans the glass/mica shields.
•
Reclose upper shutoff device (A1) and drain valve (18).
•
Put the device into operation as described under Chapter 8.
•
Refit new glasses and mica shields if cleaning was not sufficient.
Spares kits and product numbers are listed in Chapter 11 Spare Parts and
Accessories.
