3.8 Switching off the heater
After work has been completed, or when
the heater is no longer required:
- Switch off the On/Off switch (8) in the
switch cabinet.
- Close the quick action valves and both
bottle valves (30).
m
If these valves are not closed, there is a
danger of fire and explosion due to the
possible escape of uncombusted gas!
Always close the valves during breaks
and after work has been completed!
3.9 Exchanging the gas bottles
- Check whether the quick action valves
and both bottle valves (30) are closed.
- Unscrew the gas hoses.
- Screw the protective caps for the bot-
tle valves onto the gas bottles.
- Screw pressure reducer onto the
available mounting bracket.
f
Gas bottles that are full or not completely
emptied are under pressure.
Therefore, make sure that bottles with
their protective valve caps removed are
protected from severe impact (particu-
larly in the area of the valves or on the
valves themselves)!
- Connect new gas bottles (see section 3.4, „Connection and leak test“).
