Commissioning
After the initial installation the system needs to be commissioned, this document will
explain and show how to set up and commission an air to water heat pump.
Stage 1 - Electrical
Check that the system wiring is complete and connected properly before switching on the
power to the indoor and outdoor unit. Ensuring that the isolators are switched off, check
that all cables are secure, all terminals are tight and there are no bare ends exposed.
Stage 2 - Refrigeration Pipework
Before turning on the power and commissioning, you must ensure that the system has no
leaks and has the correct refrigerant charge. If you are not the installation engineer please
ensure that the pre –commissioning sheet is completed.
Stage 3 - Setting up the Controller
Switch on the power and set up the LCD controller on the indoor unit. See page 19
Stage 4 - Initial Start Up
Once the LCD controller is set the system can now start. Press either the hot water or the
heating icon on the LCD controller and the system will start. There is a 3 minute time delay
before the compressor will start.
Stage 5 - Commissioning Sheet
Once the system is fully operational and the inverter is at maximum speed 85 Hz, compete
the commission sheet by recording all data requested. A sample commissioning sheet can
be found at the end of this document.
