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
