• Open all the hydraulic circuits’ valves.
7 filling the glycol circuit
b Warning! Do not dispose of glycol into drains
and the environment.
b We recommend that you use propylene glycol
enriched with corrosive inhibitors.
• Mix 1 part propylene glycol with 2 parts water. This
mixture ensures antifreeze protection down to an exterior
temperature of -15 °C.
• Use an antifreeze test kit to ensure accurate dosing.

• In order to drain the glycol circuit after filling, use a fill pump
(2).
• Remove the caps (4) from the valves (5) and (7).
• Connect the filling pump hose (3) to the valve (5).
• Insert the hose (8) into the container and (1) and connect it
to the valve (7).
• Open valves (5) and (7) in (A) position as shown in the
illustration above.
• Start the fill pump (2) and fill the glycol circuit.
• Continue running the filling pump until completely purged of
air (8).
• Close the air trap located on the heat pump.
• Close the valve (7) in (B) position and ensure the glycol
circuit is left with a pressure of between 1.5 and 2 bars with
the aid of the manometer (6).
• Close the valve (5) in (B) position and stop the filling pump.
