Filling System
Continued
Remove the right hand front cover panel from the heat
pump. Remove circulation pump and bleed caps
Bleed air until the water flow is achieved
Bleed air from the heat exchanger high points and
check system for water leaks or drips
Tighten water fittings if necessary
Re-fit the right hand front cover panel
Check hydronic and/or hot water system for leaks
Add appropriate closed-circuit corrosion inhibitor to all
hydronic systems
Add propylene glycol to reverse cycle hydronic cooling
systems and heating systems in low ambient conditions
For cooling application -10°C glycol freezing level is
recommended and external flow switch to be fitted
Note
When filling hydronic heating/cooling systems, the cold-
water fill inlet pressure should be set above 1.5 bar
(150 Kpa)
When filling commercial hot water cylinders, bleed the
