INSTALLATION
Commissioning
• 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.

• Connect one end of the hose (3) to the trap (1).
• Insert the other end of the hose (3) into the container (4) in
order to recover any residual brine during the fi lling of the
circuit.

• In order to drain the glycol circuit after fi lling, use a fi ll pump
(2).
• Remove the caps (4) from the valves (5) and (7).
• Connect the fi lling 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) as shown in the illustration above.
• Start the fi ll pump (2) and fi ll the glycol circuit.
• Continue running the fi lling pump until completely purged of
air (8).
• Close the air trap located on the heat pump.
• Close the valve (7) 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) and stop the fi lling pump.
i The level of glycol may decrease during the
fi rst month following the commissioning of the
installation. It may also vary in accordance with the
outdoor temperature.
Any residue of glycol solution should be kept in an appropriate
container to be re-used for the next fi lling.
• Ensure any leftover glycol solution is left with the end user
and retained in a safe place.
