Initial Start Up

Please refer to controller symbols and button functions on pages 60 & 61 for further guidance on
the heat pump controls.
1. Ensure that both the outdoor and indoor units are correctly wired and plumbed prior to turning on.
2. Flush the system at 110% of system flow rate in both directions using suitable chemical.
3. Once the system has been power flushed you must now fill the system with Glycol.
4. The Glycol should be pre mixed before putting it into the system and a solar filling station is
ideal for filling the system, use the connections on the fill/flush and flow meter to add the glycol.
5. Do not put Neat Glycol into the system, failure to do this may cause the glycol to block the heat
exchanger or block the pipes within the heat emitter circuit.
6. Run the solar filling station for at least an hour to purge all the air from the system.
7. Turn on power to the indoor unit first. Then turn on power to the outdoor unit second.
