9.2.1. WATER COIL HEADERS
Each water coil header has 1 pipe connection for water supply and water return.
Due to the coil design and small effect on capacity, there is no preferential water supply and water return on
fan coil units. However we recommend water supply on the lower header of the coil.
9.2.2. WATER CONNECTION OF CONTROL VALVES
The use of regulation valves (supplied as an accessory or by the client) is mandatory to ensure that the
appliance operates correctly.
