1.4 PREPARATION FOR WALL MOUNTING (NEW INSTALLATION)
1.4.1 FAST EVO X/FLUENDO PLUS LNX
Place the securing plate marking hole Aabove the water
inlet line and to the left of the water line perpendicular.
Horizontally fix the plate to the wall using the fixings
designed for this purpose, after having drilled out holes B.
Engage the holes in the top of the chassis onto the lugs on
the securing plate.

2 OPERATION LOGIC
2.1 FAST EVO X/FLUENDO PLUS LNX
When water faucet is turned on, if the water flowrate
is over (>2 l/mn), electrical impulse will be input
controller (19) which produced by water flow
sensor (11).
The controller (11) is enabled and it drive ignitor
(12) to start process. Discharge electrode (4)
produce electricity spark. At the same time, it supply
power for bidirectional valve (9 10) and solenoid
and step motor (20) and solenoid coil (21).
Ignitor (12) control step motor (20) make the
solenoid coil (21), generate magnetic force. Then
the contoller (11) re-controk step motor (20)
operation valve (7) open to position of soft ignition.
After bidirectional valve (9 10)got power, normally
open valve (9) turn OFF, normally closed valve
(10)tun ON. In the function of pressure, diaphragm
valve (6) is turned on by differential pressure.
After soft ignition light on, ionization pole (5) can
sense flame signal ignition (12) control discharge
electrode (4) to stop ignite.
Base on deliver water NTC (14) and water flow
sensor (19) controller can adjust deliver water
temperature to setting point by automate step motor
(7)to open corresponding position. Water is heated
to setting temperature in heat exchanger (2)
Overheat switch (16) cascade with deliver
overheat switch (22) detect the temperature and
mde an error .
Rod (17), can adjust water flow, filter (18) can pick
out the impurity of water, water flow sensor (19)
can measure water flow rate.
2 LR20 1,5 V batteries (13) parallele connection.

2.2 FAST R X/BRD LNX
Turn on the power switch, when the tap is turned on, the water flow is more than (2L/min) or the water
pressure is higher than 0.2bar, the micro-switch (15) gives the electrical signal to the ignition controller (A).
Control PCB to receive the signal, drive the ignition, 0.5s after the solenoid valve (20) open. Gas from the
intake connection (21) goes to the solenoid valve (20), and then goes to the gas regulating shaft (19), goes
to the linkage body (14), next goes to manifold and burner (B), start ignition. Ignition is successful, flame
electrode (C) sensor provides flame signal to controller box, and ignition pin (C) stop spark and machine
continue to work.
The thermostat (D) monitor water temperature inside HEX, when the water temperature is more than 85℃,
the machine stops working.

The thermostat (E) monitor water temperature inside HEX, when exhaust gas goes out of flue hood and flue
hood temperature exceeds 145 ℃, the machine stops working. (Machine only for RU market has this
function)

The burner is on till the outlet limit temperature.
The temperature is checked by the outlet NTC.
During the flow rate variations and during the
ignition the power is managed by the T and the
flow rate measure through the proportional flow
met.
