HYDRAULIC CONNECTIONS
To protect against injury or damage to the unit or room, the hydraulic
connections must be made by qualified personnel only.
The coils are fitted with a 'female' hydraulic connection and a turning nut with a flat face and
an O ring (supplied by
CIAT ), an air bleed valve and a drain valve (diameter ½" and ¾").
Water always flows into the bottom of the coil and exits at the top.
To install a control valve with a flat face ( CIAT option in a kit) (fig. 7) :
●
2-way valve: screw the valve and seal supplied directly on the hydraulic
connections at the coil's inlet (bottom):
- 2-way valve, 2 pipe version
(fig. 7a)
- 2-way valves, 4 pipe version (fig. 7b)
●
3-track valve + integrated bypass: add the copper piping (supplied) before
installing the valve:
- 4-track valve, 2 pipe version
