5. Commissioning
5.3 Commissioning (initial and re-commissioning)
The commissioning or re-commissioning of the operational system is carried out as follows:
The gate valves on the device are fully opened, and the pipe system is completely vented.
The heat pump is switched on via the main switch. The regulator on the fan side of the heat
pump starts up and, after a self-test, displays the current water inlet and water outlet
temperature.
In the event of very cold water and low outside temperatures, the amount of water
must, under certain circumstances, be slightly reduced by the outlet valve. With the
compressor running, the uninsulated copper wire on the compressor should be at a
temperature of about 60°C.
When operating a heat pump with hot gas defrosting below the frost line, it must be ensured
that water is prevented with certainty from freezing.
Frost damage is excluded from any warranty.
5.4 Condensate discharge test
If installed outdoors, the condensate can drain away freely. If installed in the plant room, a
drainage hose with a removable connection must be provided which is fed into the
wastewater system. The function of the condensate discharge should be checked using a
watering can filled with water.
