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.
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 drain valve at the lowest point to the open position.
4.13 Restart after a long term stop
When the unit is restarted after a long term shutdown (trail running included), it is normal that outlet
water is unclean. Keep the tap on until the water runs clean and free of debris.
