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.

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.
5 COMMISSIONING SYSTEM
IMPORTANT: It is the responsibility of the installer to ensure that the system is properly commissioned and the end
user instructed in the safe operation of the equipment.
The thermostat on the immersion heater should be adjusted to trip at 60°C. This is the ideal temperature to prolong
element life in hard water areas. Scale on the sheath builds up more rapidly at temperatures above this causing the
element to overheat and premature failure can occur. Higher temperatures without additional controls would result in
scalding. In known hard water areas the use of a scale inhibitor is also recommended.
In addition to the thermostat the thermal cut-out will switch power off to the element should the thermostat
malfunction, causing an excessive rise in water temperature. The thermal cut-out can be reset manually after the fault
has been corrected
