TROUBLESHOOTING.

Attention:
- Incorrectly managing thermostats, safety valves
and/or other types of valves can cause the tank
to break. Every operation on the unit must be
done scrupulously following the instructions
that concern it.
- The electrical supply voltage must always be
cut off before cutting off the hydraulic supply.
- Regularly check safety valve operation, making
it open to make sure water flows out with no
problem.
