INSTALLATION
12 Commissioning
i
At the time of commissioning, complete all relevant
sections of the Benchmark Checklist located on the
inside back pages of this document
• Check that the differential breaker is installed.
• Check that the hydraulic and electrical connections are correct.
• Check that the fi lter on the heat pump return is installed.
• Check the airtightness of the connections.
• Open all the hydraulic circuits’ valves.
12.1 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.
• Using a fl at wrench (2), open the trap (1) a ¼ turn.
• In order to drain the glycol circuit after fi lling, use a fi ll 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.
12.2 Activating the heat pump
