9.1 Filling the system
The system should have the correct corrosion inhibitor added to the correct volume before
filling with water. The system should be filled cold through a fill loop via a filling loop isolation
valve. Once the system pressure has reached 1 bar air should begin to dispel through the
system auto air vents. Continue to fill until all air is dispelled. To bleed the heat pump of air
a Schrader bleed valve is located above the circulating pump as shown in Figure 23. By
surpassing the valve air can escape from the heat pump heat exchanger. However please
ensure that the Schrader cap in replaced after bleeding. Once all perceived are has been
removed the circulating pumps can be ran manually to remove trapped air, please see Section
9.1.1. The heat pump will require bleeding again during the running of the circulating pump.
