4.11 Hydraulic safety unit efficiency check
The hydraulic unit efficiency is very important to prevent any overpressures inside the tank (that
would damage it), and allows the user to safely operate the equipment. Periodically check the
efficiency of the hydraulic safety unit, according to the instructions provided by the manufacturer.
Follow the instructions provided by the manufacturer. During the check clean the unit and remove
any limestone scales.
4.12 Unit emptying
Should the unit be going to remain unused for a prolonged time, we recommend that you empty it.
In this case proceed as follows:
•
cut off the power supply and the main water supply;
•
open a hot water tap to allow air to flow in;
•
turn the emptying knob on the hydraulic safety unit to the open position;
•
verify that the discharge connector of the hydraulic safety unit is connected to a drain as
specified in par. 3.1.1.
4.13 Restart after a long term stop
When the unit is restarted after a long-term stop (trail running included), it is normal that outlet water
is unclean. Keep the tap on and the water will be clean soon.
