Therma V R32 Installation Instructions.
First two weeks: Blocked filters and/or air pockets
Flow rate alarms are likely to occur during the first two weeks after commissioning; this is due to the formation of
air-pockets which may occur and temporarily affect the flow-rate. In most cases, the air will migrate to the auto-air
vents (AAV) and release without any requirement for intervention.
Equally, if any sediments are in the hydronic pipework, they will be caught by the internal strainer. Blockages in the
strainer can cause CH14 alarms. In this case, the strainers will need to be cleaned
Recommendation : once the unit has been installed, advise the customers that it is quite likely and normal for a CH14 alarm
to occur in the first two weeks. This will give the customer reassurance if and when the fault does arise!
If the cause was air, then a simple power reset could allow the system to continue working as normal, once the pocket of air
has made its way to the AAV
