Hydraulic Connection; Wiring Diagrams - Joannes DRY 20 Handbuch

INSTALLATION
The installation of the boiler must only be carried out by Qualified Personnel, following the indications of the
Manufacturer and in compliance with all the laws and regulations which control the subject. It is particularly
recommended that the regulations in the matter of safety are observed and those that regulate the construc-
tion and location of the flue pipes.

HYDRAULIC CONNECTION

Carry out the hydraulic connection of the appliance complying with the directions placed close to each
connection and the ones related in figure 1 of this booklet. The connection must be made so that the pipes
are free from tension and it is compulsory to assemble a safety valve on the heating circuit, at a point as
near as possible to the boiler, without there being, between said boiler and valve, any obstruction or
intercepting device.
The appliance is not equipped with the expansion tank; its connec-
tion therefore must be carried out by the installer. For such purpose
we remind that the system pressure, when cold, must be between 0.5
and 1.5 bars inclusive.
CONNECTION TO THE FLUE PIPE
It is advised to connect the boiler to a sound flue pipe, built in compli-
ance with the current regulations. The conduit between the boiler and
the flue must be made from a material suitable for this purpose or
else resistant to temperature and corrosion. At the junction points it is
advisable to cure the tightness and thermally insulate all the conduit
between boiler and chimney in order to avoid the formation of con-
densation.

WIRING DIAGRAMS

Carry out the connection of the circulating pump, the burner and the
possible room thermostat by observing the directions in the diagrams
attached (Fig.s 6 & 7). It is recommended to interpose a bipolar switch
between the power supply and the appliance, with contact openings
of at least 3 mm, provided with fuses of 5 A max.
Use the cable grips supplied for all electrical connections.
In addition it is advisable to connect the appliance to a sound earth-
ing system.
Lamborghini Calor s.p.a, declines any responsibility for damage to
persons or things caused by the non-connection of the appliance to
a sound earthing system.
N.B.: The burner cable (Pos.1 Fig. 5) can be positioned, according to
the necessity of the user, to the right or the left.
