Valve connections
The connections of the valves to the fan coil are illus-
trated on page 37-53.
The positions of the coil manifolds are shown on page
19-21.
Two- or three-way valves
The valves are supplied with the connecting pipes and
must be fitted by the installer.
The elbows are connected to the fan coil using flared
joints fitted with flat gaskets.
