Operation safety:
Water distiller is based on water evaporation method. Due to that fact, it
heats water up to boiling temperature. Be careful with water distiller
surfaces and distillated water – they can be extremely hot.
Never open working distiller. Before any maintenance make sure that
water distiller has cooled down.
 Water distillers with built in tank (models Liston A 1104, Liston A 1110,
Liston A 1125) are equipped with automatic control system and will
automatically switch off if tank is full. Nevertheless, water distiller is a
powerful electric equipment that works with liquids and it has to be
periodically observed by personnel while operating.
 Water distillers without built in tank (models Liston A 1204, Liston A 1210)
are not equipped with automatic control system and must be controlled by
personnel all the time while operating. Make sure that distillate receptacle
is big enough and not full, before starting operation

4.1. When the water distiller is switched ON using the POWER switch (this
switch is lit in the ON position), the raw water supply valve 21 is activated
(Figure 1). As soon as the evaporator water level reaches the bottom
sensor 9, the automatic device switches the heaters 17 ON.
4.2. The operation mode is achieved maximum in 15 min in the case of the
Liston A 1104 water still and maximum in 30 min in the case of the Liston A
1110 and Liston A 1125 water stills.
4.3. When water boils in the evaporator 2, steam forms, than separated and
enters in the condenser 6 via the channel 5. The separator consists of the
steam floe splitter 3 and the nozzle 4 located inside the channel 5.
4.4. Steam condenses in the condenser walls and heat exchanger 19 with the
formation of distilled water. The evaporator water level is maintained
automatically by means of the equalizer 7 due to the water overflow in the
drain pipe of the equalizer 18.
4.5.The condenser 6 housing is simultaneously a distilled water collector.
4.6.Distilled water can be produced in the continuous mode, with the collector
6 unused by flowing distillate in other containers via the drain tap 28
(Figure 2) located on the front panel.

5.2. The water distiller is started by setting the S1 toggle switch to ON, at the
same time the switch LED (POWER) is lit and supply voltage is applied to
the A1 automatic device PCB that activates the Y1 inlet valve (Pos. 21 in
Figure 1), at the same time the MODE red LED is lit (HL1 LED).
5.3. When the water level in the evaporator 2 (Figure 1) reaches the bottom
sensor 9 (the LOW contact in Figures 3 and 4), the KM1.1 starter is
activated and voltage is applied to the EK heaters.
5.4. When the evaporator water level lowers below the admissible level
(below the sensor 9 level) the automatic device switches the heater OFF.
5.5. The KK1 thermal switch contact ensures an additional emergency
shutdown of the water still in the case of water level lowering and the
heater temperature rise over 150˚С.
5.6. When the distillate collector is filled up to the level sensor 11 (Figure 1)
(the HIGH contact in Figures 3 and 4), the automatic device stops heating
water and shuts the Y1 water supply inlet valve off. The MODE green LED
(HL1) goes out. When distillate is drained from the collector, the automatic
device opens the Y1 inlet valve and activates water heating, at the same
time the MODE LED is lit (HL1 LED).
5.7. When water overflows in the evaporator 2 (Figure 1) or equalizer 7, the
water level reaches the top level control sensor in the evaporator 7 or level
sensor in the equalizer 24 (ALARM contact in Figures 3 and 4), the
automatic device switches the heater and inlet valve OFF and the FAILURE
led (HL2) is lit. To continue the operation you should switch the S1 power
switch OFF (POWER), eliminate the cause of overflow and switch the S1
switch (POWER) ON.
5.8. Upon completion of operation you should cut the water distiller of the
mains. Switch the S1 toggle switch (POWER) off and BA input circuit
breaker.

6.1. Prior to the start of the water still, it should be connected to the water
supply system through the pipe 7 (Figure 5) and you should wait until
water runs from the cooling water drain pipe 12, to which the cooling
water removal hose is connected. The nozzle 9 automatically controls the
water flow rate.
6.2. When the power switch 2 is switched ON (the switch is lit when in ON
position), the automatic device switched the electric heater 3 and raw
water is fed to the evaporator via the pipe 7.
6.3. Raw water boils in the evaporator 10, steam forms and is separated and
fed into the condenser 6. Steam condenses on the condenser walls and in
the heat exchanger with formation of distilled water. The equalizer
maintains the water level in the evaporator due to water overflow in the
drain pipe
6.4. Distillate flows out through the distillate drain pipe 5. Additional
containers should be used to collect distillate.
7. Before installation
Installation of the equipment must be done only by qualified personnel and
only after reading operating manual
7.1.The water distillers are designed for table mounting and should be placed
on a solid and flat surface. Use level and adjustable foots (for Liston A 1110
and Liston A 1125) to place water distiller.
7.2.Water distillers should be installed in rooms with water supply system,
water supply control valve, sewage system, electric network (singlephase alternate current network with a rated voltage of 220-240 VAC for
the Liston A 1104, Liston A 1204 and three-phase alternate current
network with a rated voltage of 380-400 VAC for the Liston A 1110, Liston
A 1125 and Liston A 1210 and grounding. Do not use the water distillers
without connecting its grounding terminal to the protective grounding
bus
13

7.3.During the operation, the water distiller produces gases, as well as steam
and heat from raw water, because of this it is reasonable to have sufficient
natural ventilation or exhaust ventilation in the premises.
7.4. Raw water incoming pressure should be 0.15-0.5 MPa. Otherwise, the
stable water distiller operation is not guaranteed.
7.5. Prior to the connection of the water distiller to mains, check visually the
cord, plug and socket for failures.
8. Water distiller with built in tank
installation
8.1. Attach the fitting with 1/2'' male thread through the sealing tape to the
tap 28 (Figure 2). Connect the silicone tube to the fitting and attach a
plastic tie
8.2. Attach the fitting with 1/2'' male thread through the sealing tape to the
tap 27 (Figure 2).
8.3. Connect the drain hoses, one to the fitting 26 for the cooling water drain
(Figure 2) and another to the tap fitting 27 for the wastewater drain from
the evaporator. Tighten the connections of hoses and fittings with the
clamps supplied.
8.4. IMPORTANT! The hose for the cooling water drain from the fitting 26
(Figure 2) should be located at a slant and it must not have any twists
and kinks. If necessary, shorten the hose. The level difference between
the fitting 26 and the location of the hose connection to the sewage
system should be at least 0.3 m. The hose should not abut against the
internal sewage pipe wall.
8.5. Otherwise, the water level in the evaporator 2 (Figure 1) and equalizer 7
begins to rise and reaches the top level sensor 23 or level sensor 24 and
the automatic device will stop the water still and the ALARM red LED will
be lit).
8.6. Install gaskets in the filling hose nuts.
8.7. Connect the filling hose to the fitting 25 (Figure 2).
8.8. Connect the filling hose to the water supply system through a valve or a
ball valve.
8.9. Check, that the bottom level sensor 9 (Figure 1) does not contact the walls
of the evaporator 2 and steam flow dissector 3. Otherwise, the heaters
14
Copyright Liston, LLC 2015
start to operate in the absence of a sufficient water level. This will cause an
emergency shutdown of the water still due to the electric heater
temperature rise above 150 °C.
8.10.
Check, that the distillate level sensor 11 (Figure 1) does not contact
the walls of the condenser 6 and exchanger 19. Otherwise, the automatic
device will assume that the collector is filled with distillate, turn off water
heating, and shut the inlet water supply valve off.
8.11.
Check that the sensors 23 (Figure 1) and 24 do not contact the walls
of the evaporator 2 and equalizer 7. Otherwise, the automatic device
would assume that there was an overflow of water and turn off the water
distiller, and the ALARM red LED will be lit.
8.12.
Before connecting to the mains, make sure that the voltage and
power correspond with the information on the water distillers. The mains
should be equipped with a circuit breaker in accordance with the water
still power for a rated current of 20 A (Liston A 1104), 40 A (for Liston A
1110), and 100 A (Liston A 1125). The water still are connected to the
mains using the mains input circuit breaker (Figure 6, Figure 7) to be
installed by the consumer and intended for protection against overloads
and short-circuits of electrical circuits having a voltage of 380-400 VAC,
operative ON and OFF of these circuits.
8.13.
The BA circuit breaker is not supplied, should be purchased by the
consumer and selected based on the calculation of the 10•In overcurrent
tripping setting (where In is a rated current).

9. Water distiller without built in tank
installation
9.1. IMPORTANT: In order to avoid manual adjustment of the water flow
through the tap, the orifice 9, which throttles the flow of water in the
range of 0.2-0.5 MPa (the optimum pressure is 0.15 MPa) is installed in this
water distiller. This provides the minimum flow and maximum
performance of the water distiller.
9.2. The throttle orifice in the nozzle has a small cross-section and can be
clogged with particles of sand or salt-containing sediments. Therefore, to
avoid clogging of the nozzle, as well as for monitoring pressure in system
of water supply, it is recommended to install in the water supply system a
pressure regulator with a pressure gauge and a self-cleaning filter (with
100 micron filtration fineness).
9.3. In case of clogging the nozzle, the water distiller begins to emit steam, the
productivity decreases. In the absence of flow of water through the nozzle,
the water level in the evaporator becomes insufficient, overheating of the
heater will occur leading to triggering of the thermostat 13 and the full
disabling of the water distiller.
9.4. In the case of frequent nozzle clogging, if the filter is not installed, the
nozzle may be removed from the water distiller. The consumption of water
should be controlled with a valve supplied. The flow rate is considered
optimal, when the temperature at the outlet of the heat exchanger (water
temperature Equalizer) is about 70-80 degrees Celsius.
9.5. Install water distiller on the table, using the level gauge and avoiding
slants.
9.6. Attach the silicone tube (L = 0.5 m) to the distillate drain pipe 5.
9.7. Connect the drain hose to the cooling water drain pipe 12.
9.8. Tighten the connection of the hose and the cooling water drain pipe 12
with the screw clamp supplied.
9.9. IMPORTANT: The drain from the drain hole should be free: the cooling
water drain hose should be at a slant, and it should not have any twists
and kinks (if necessary, reduce the length of the hose). The height
difference between the drain hole and location of connection of the hose
to the sewage system should be at least 0.3 m. Otherwise, an air lock may
17
Copyright Liston, LLC 2015
appear, the water level in the evaporator will begin to rise and overflow of
water from the equalizer will start.
9.10.
Connect the 1/2” ball valve (supplied) through the sealing strip to
the pipe 7 (Figure 5).
9.11.
Connect one end of the 1/2” flexible water piping to the ball valve
and the other end to the water supply system through the ½ “ brass filter

10.3.
Open the valve for the raw water supply to the water distiller.
10.4.
Check that the bottom level sensor 9 (Figure 1) does not contact the
walls of the evaporator 2 and steam flow dissector 3. Otherwise, the
heaters start to operate in the absence of a sufficient water level. This will
cause an emergency shutdown of the water still due to the electric heater
temperature rise above 150 °C.
18
Copyright Liston, LLC 2015
10.5.
Check that the distillate level sensor 11 (Figure 1) does not contact
the walls of the condenser 6 and exchanger 19. Otherwise, the automatic
device will assume that the collector is filled with distillate, turn off water
heating, and shut the inlet water supply valve off.
10.6.
Check that the sensors 23 (Figure 1) and 24 do not contact the walls
of the evaporator 2 and equalizer 7. Otherwise, the automatic device

10.7.
To start the water still push the POWER button located on the front
panel and this button should be lit. The raw water supply valve will be
activated.
10.8.
When the evaporator water level reaches a value determined by the
bottom sensor, the heaters are activated and the MODE LED should be lit.
In 15 min for the Liston A 1104 or in 30 min for the Liston A 1110 and
Liston A 1125, the water still should achieve the operating mode.
10.9.
At initial start of the water stills after a long break in the work, and
after maintenance work, it is necessary to perform an hour cycle followed
by draining water from the evaporator and collector.
10.10. Distilled water can be discharged continuously into the prepared
containers, or use the built-in storage tank. When filling the built-in
storage tank, the distillate level sensor 11 is activated (Figure 1), the
heating elements are switched off, and the MODE LED goes out.
10.11.
Upon completion of work, disconnect the water still from the mains,
to do this, press the POWER button to 0 position. Then the POWER and
MODE LEDs will go out.
10.12. Close the valve for the raw water supply in the water distiller.

11.2.
When you first turn on the water still, fill the evaporator pos. 10 with
water. To do this, remove the silicone tube from the equalizer and remove
the condenser pos.6 by pulling it up. Next, fill up the evaporator with
water until the heating elements do not disappear completely under
water. For the Liston A1210 and water distiller, before filling the
evaporator, you must ensure that tap for water draining from the
evaporator is CLOSED.
11.3.
Fully open the ½" ball valve for supplying raw water to the water
distiller, wait until water is flowing out of the cooling water drain pipe pos.
12, to which the cooling water removal hose is connected.
11.4.
WARNING! Before each use, make sure that the heating elements are
completely covered with raw water, otherwise the electric heaters will
work in the absence of sufficient water. This will cause an emergency
shutdown of the water still due to the electric heater temperature above
130-150 ˚C.
11.5.
For recovery of the distiller after heater overheating, wait until the
heaters are cooled down, and then push the lock button located on the
thermal switch housing. (Pos. 13, Figure 5)
11.6.
To start the water still push the POWER button located on the front
panel and this button should be lit.
11.7.
In 15 for the Liston A 1204 or in 30 min for the Liston A 1210 the
