Radiator Thermostat RAS-C2 Combi
BI-DIRECTIONAL VALVE WITH FLOW-SELECTABLE FEATURE
Installation of valve
Troubleshooting
The valve is a bi-directional valve * and can be installed
horizontally or vertically in either the flow or return
pipe.
A built in flow direction selection feature can be used to
eliminate the risk of water hammer.
In the unlikely event of water hammer being encountered
turn the setting ring (see diagram 4) to the other setting.
Alternatively if commissioning the whole system,
establish the flow direction through each valve using
the diagrams below.
If the flow direction needs to be changed there is
no need to remove the valve, simply turn the setting
ring.
