Filling System
Once the system has been correctly connected and
installed as instruction provided here within to heating,
cooling or hot water system, please start filling the system
with fresh water ONLY
Note
If connecting to previously used hydronic heating, cooling or
hot water system, it is important to make sure that heat
pump is properly connected, this involves ensuring the heat
pump is properly power flushed and cleaned effectively
ready for use prior to the heat pump connection/installation
Water Quality
When filling the system, it is essential that the water quality is
checked. The water quality of most public supplies is suitable
for the heat pump system.
Water quality from water bores, springs and wells are
generally not suitable or recommended for the heat pump
system.
Do not connect heat pump system to water supplies with
impurity levels above the following
▪ Total dissolved solids 1000 mg/litre
▪ Chloride 250mg/litre
▪ pH Keep between 6.0 to 9.5 – No less than 6.0 pH will
become acidic
When filling the system air must be bled from all components
in the system (Example. Hydronic manifolds, fan coil units,
pumps, radiators, buffer tanks and hot water tanks).
