main water shut-off valve, turn on the cold water valve of
the heater tap, letting the necessary water quantity move
through it in order to remove pollution and air, which are
present in the water system.
d) Place the filtering sieve in the left stub pipe of the tap
(fig. 6.)f) The heater is mounted on two stub pipes (on top
of the M 18x2 tap), and the spout or sprinkling set is moun-
ted on the bottom end (fig. 7).
g) Tighten the nuts of the heater uniformly to the tap, avo-
iding the tilting of the heater (fig. 8).
NOTE!
h) After connecting the heater to the water supply system,
deaerate the heater by opening the hot water tap valve
(fig. 9) until the moment of gaining certainty that there is
no air in the water system.
i) Switch on the power supply ONLY after the prior de-
aeration of the heater as per section 7.1 h (fig. 10)
There is a possibility to install the DAFI water heater on
the existing wall bathroom tap or kitchen faucet. In lieu of
the spout, the following items can be screw into the tap:
a) an elbow with M 22 x 1.5 and G ½” female threads to
which the DAFI heater tap is screwed in (fig. 11a).
b) reducer (shower connector) with the M 22 x 1.5 female
thread and G 1/2’’ male thread, to which the G1/2” elbow
and then the DAFI heater tap are screwed in (fig. 11b).
Further installation operations are the same as in the case
of installation of the heater at the end of the water supply
pipe running out of the wall.
7.2 Installation of the heater with the connection
In case of installation of the heater with the connection, use
only the DAFI heater with the degree of protection against wa-
ter penetration - IPX4 (fig. 12).
In this system, the connection should be preceded by the
DAFI shut-off valve (fig. 13).
In order to install the heater with the connection, the connecting
element, which is mounted on the pipe that supplies water is
used instead of the tap with the spout.
Before the installation of the heater, install the shut-off valve
on the pipe and let the necessary water through it in order to
remove the contaminants and the air, which are present in the
water system.
Install the connection and fix the DAFI water heater to it. During
this activity, it is important to supply the cold water into the stub
pipe of the heater in accordance with the marking (arrows) at
