our
customer, they are shown how to use it, and it is signed by them. Please instruct your
customer that they must have their Log Book with them whenever they
contact a service engineer or us.
Preliminar
y electrical system checks to ensure electrical safety must be carried out
by a competent person i.e. polarity, earth continuity, resistance to earth and short
circuit.
FILLING THE HEATING SYSTEM:
Remove the panels of the case and lower the control panel (see section 3.3 for
further information).
Open the central heating flow and return cocks supplied with the connection kit
(there are two isolation points on the return connection).

4.1 INITIAL PREPARATION
Boiler microSYSTEM
15 RFFI
Cylinder
= Ideal
= Possible
The microSYSTEM is able to be connected to a specially designed kit for the
management of D.H.W. production. This kit gives priority to production of D.H.W. unlike
traditional systems where the boiler power is split between C.H. and D.H.W. This
generally enables a smaller storage cylinder to be chosen as the boiler’s full output
will be channelled into the cylinder allowing for a quick heat-up.
The kit (ARISTON part number 706329) can be obtained from an ARISTON supplier.
The kit consits of:
1) Electronic module able to plug into the boiler’s P.C.B;
2) 3-way priority valve with actuator for connection to the boiler’s flow outlet;
3) A limit thermostat (80˚C) to check the water temperature of the heating flow to the
cylinder, to be installed within the boiler;
4)
Pipes and accessories.
