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):
