3.3 - SYSTEM WATER REFERENCE VALUES

• pH: .................................................................................................. 6,5 ÷ 7,8
• Electrical conductivity: .................................................................... included between 250 and 800 µS/cm
• Total hardness: ............................................................................... included between 5 and 20 °F
• Total iron: ........................................................................................ lower than 0,2 ppm
• Manganese: .................................................................................... lower than 0,05 ppm
• Chlorides: ....................................................................................... lower than 250 ppm
• Sulphur ions: .................................................................................. absent
• Ammonia ions: ................................................................................ absent
If total hardness is higher than 20°F or if some reference values of make-up water do not respect the indicated
limits, please contact our pre-sale service to determine the treatments to be implemented.
Well or aquifer water not coming from an aqueduct must always be carefully analysed and, if necessary,
treated with opportune treating systems. In case of installation of a softener, in addition to following the pre-
scriptions of the manufacturer, adjust outlet water hardness not below 5°F (also carrying out pH and salinity
tests) and check the concentration of outlet chlorides after resins regeneration.
In case of danger of frost, empty the system and insert antifreeze liquid in a percentage compliant
with the minimum reachable temperatures.
Water and ethylene glycol solutions used as heat carrier fluid in place of water cause a reduction of the unit
performances. Add water with a maximum percentage of 35% of ethylene glycol (equal to a protection up
to -20°C).

3.4 - HYDRAULIC SYSTEM FILLING

Once the hydraulic connections have been completed, it is necessary to proceed with filling of the system.
Simultaneously, it is necessary to vent the air inside the pipes and of the appliance by beans of the air vents
on the circuit and on the appliance.
Initially, with the water circuit empty, the machine must not be connected to the mains power supply.
The machine must be powered and the circulation pump started only in the final filling phases of the hydraulic
circuit. It is advised to activate the temporary forcing function of the circulation pump for 15 minutes.
If an external auxiliary pump is used, the latter must also be started only in the final filling phases of the circuit.
The operating pressure of the system must not exceed 1,5 BAR when the pump is off.
In any case, to check for possible leaks of the system during test phase, it is advised to increase the test
pressure (maximum pressure of 3 bar) and then to release it to reach operating pressure.

3.5 - CIRCULATION PUMP ALARM

If, during first start-up, error E06 appears on the display of the control panel after the start of the circulator E06:
a. Check that the valves of the system are open.
b. Check that at least one utility with circuit open is present.
c. Check that the external sieve filter is not clogged.
d. Check that there are no air pockets inside the circuit.
e. Check that water pressure of the system is correct.
f. Check that the circulator is not blocked.
To delete the pump alarm and restore operation, press the Reset icon on the display and confirm.
