Installation of the KA system 1191:
 The thermostatic regulation valve must be placed on the return to the boiler.
 During the installations check that the humpback is on the same side as the return of
the primary or the boiler.
 The lockshield valve must be placed on the inlet of the boiler.
 During the installations check that the humpback is placed on the opposite side of the
primary or the boiler.
Installation of the thermostatic head for fixed point :
 Remove the protection cap on the thermostatic valve.
 Regulate the thermostatic head on the max value to ease the installation and screw it
on.
 Once this operation is finished the head must be regulated on the temperature
required.
 Place the bulb of the head on the fixing device..
 To regulate the flow:
o Unscrew the ABS cap "A".
o With an Allen Key CH.10 close the obturator without forcing;
o Open the obturator with a number of loops according to the ones in the flow
diagram;
o Screw back the ABS "A" cap.
 NOTE: we recommend to remove the pressure after the installation test has been
made. A pressure difference between the inlet and outlet of the valve higher than 1 bar
could cause the displacement of the o-ring.
 Check that the thermostatic head or the actuator is correctly
screwed down to the stroke.
 Check the boiler temperature
 Check the prevalence of the boiler pump (balance the mixing by
reducing the Kv of the balancing ball valve n. 3) see page 4).
 Check the Bypass calibration (if installed)
 Check the lockshield valve KA1191 which must be completely open
 Check the capillary of the thermostatic head which must not be
damaged or chocked.
 Check that the assembly direction has been correctly followed
during the installation.
