2. Operational Principles and Technological Process
For the technological process, please refer to Fig.1.
Electrolytic water meeting the requirements (With electrical resistivity >lMQ/ cm, and
deionized or redistilled water in electronic and analysis industries can be used for this
purpose.) , after being put into the anode chamber of electrolytic cell, when power is
switched on ,will be decomposed at once at the anode : ZHz O : 4H+ + 2O2. The
decomposed negative oxyanion (O') will immediately release electron to form oxygen (Oz),
which will then be discharged from the anode chamber, with some water, into the water tank.
The water can be used circularly, and oxygen will be discharged from the small hole of the
top cover of the water tank into the atmosphere. The hydrogen proton, in the form of aqua ion
(H* 'XHz O), and under the action of electric field force , through SPE ion membrane, will
1,

OPERATION MANUAL FOR QL HYDROGEN GENERATORS
arrive in the cathode to absorb electron to form hydrogen ,which will then be discharged
from the cathode chamber into the gas/water separator, where most of water it brought with
from the electrolytic cell will be removed . The hydrogen with lifile water will be under
moisture absorption of the desiccator, with its purity thus reaching99.997 0/o or above. When
the condensed water in the gas/water separator is accumulated to a certain quantity, it will
raise the float and be discharged from the outlet at the bottom of the gas/water separator into
the water tank for recycling. The float, after the discharging, will return immediately to its
original position, and the water level of the gas/water separator thus remains constant.

For the electrical principles of a complete set of generator, please refer to Fig. 2. The
whole electrical system is mainly composed of four parts: a power supply system for
electrolysis, main control subcontrol ald a display panel. When the power switch SWI is
pressed , the generator will go into operation. In the course of electrolytic process, when air
pressure reaches the preset value, the pressure transducer SEN will start to take control to
make electrolytic current decreasing along with rising of air pressure, thus enabling output of
the generated
hydrogen, under the stable pressure, to meet the demand of the consumption
automatically-

OPERATION MANUAL FOR QL HYDROGEN GENERATORS
In addition, the generators, for ensuring normal operation, are equipped with three
alarming protection sYstems.
3.1 OverpressureAlarming
If the output pressure is out of control and rises to 0.46 MPa
because
of being strongly
shaken or something is wrong with its certain parts in the course of operation, the generator
will beep four times with an interval and automatically cut off the power supply for
electrolysis and stop the electrolysis for realiztngthe overpressure protection. At that time the
front board will show that hydrogen output is zero with pressure alarming light (red) on'
End-users should release the pressure and restart up the generator after ensuring that power
connection is good with no shaking. If the above-mentioned phenomenon still reoccurs, it
can be considered as an failure, end-users should inform the manufacturer for maintenance'
3.2 Failure Alarming .
When the pressure controller is failure or other failure, the Failure alarm will light in the
front board, At this point, the user should shut down and contact the manufacture at once'
3.3 WaterAccumulatedAlarming
If the instrument
is running
without
pressure (or pressure is "zero") for long time, the
water in gas/water
separator
will arrive the upper limit, then, the instrument will stop
electrolysis and send ;beep" alarming ,the alarming light in front board is red. Now, the
operatoi should close the outlet of H2 in the back board, and restart the instrument. (look at

(l) ReplaceWay
O Take away the sealing film in water inlet and Hz & watet outlet. Let the cell erected,
then little water will flow out.
@ Fix the frame of the cell with M5 bolts in right place.
@ Connect the water inlet and water tank outlet with O6x9 Silicone pipe. At the same time,
connect oxygen & water outlet and water tank cycle water inlet with another silicone pipe.
@ Connect the power positive line to the positive plate of cell, Negative line is connected
to negative plate. Fix and tighten with M6 bolts.
@ Connect Hz outlet andHz& water Separator inlet. Must tighten the nuts in the joints, in
cast ofleakage.
(2) Common Faults
O The electrolysis efficiency decline, the flow display
is less than 50ml/min, It can be
judged as electrolyzer failure
@ The cell is made up with one or several until cells. The until cell is separated into Anode
chamber and Cathode chamber by SPE membrane. There are oxygen gas and water inAnode
chamber, and hydrogen gas and water in cathode chamber .If there is holes in SPE membrane,
The hydrogen gas will penetrate
into
Anode chamber, then the output pressure cannot reach
the set pressgre. There will be little or no gas pocket in gas/water separator. And there are
morg gas pocket in the gas/water separator outlet. It can be judged as cell Reverse osmosis
failure. The cell should be replaced.

OPERATION MANUAL FOR QL HYDROGEN GENERATORS
(3 ) Considerations
O Must use deionized or redistilled water with electrical resistivity >lMC)/ cm, If the
substandard
water will damage the cell.
@ Must connect the power line right.
@ There must be water in the cell in any time. If you donot use that for long time, it
should be put some water in the cell.
5.4.2 Gasl Water Separator

SmalI Holes
W, inl
( 1) Gas/ water separator function
The Hz & water from the cell enter into gas/water separator through gas/water separator H2 &
water inlet. When the condensate water in gas/water separator is accumulated to certain
amount, (about at 112 of outer cover), the float will float. The red sealed gasket will be
divorced from the top of vertebral, the condensate water under the Hydrogen gas pressure,
will enter into the water tank through the small holes of the vertebral. After dewatering, the
float will diaplasis at once . Reciprocate like this. The water level in the gas/water separator
is kept constant, it can separate the water and gas.
(2) Leakage Faults
The hydrogen gas willbe leaked because of the bad seal between red sealed gasket and
the top of vertebral, it will appear that the Hydrogen gas output pressure cannot reach the set
value or the pressure is not under stable and there is no or little condensate water in gas/water
separator, the gas pocket will flow quickly in the return water inlet. It can be judged as
gas/water separator faults. The reason of bad seal is followed:
oa

OPERATION MANUAL FOR QL HYDROGEN GENERATORS
O The surface of red sealed gasket is unevent because of long time using.
@ It appears loose in the plexiglass tablet, it can cause the sealed gasket float.
@ The read sealed gaske expand because of touching the water for long time, it can cause
that there will be sphere between plexiglass tablet.
@ There is skin needling in the top of vertebral;
@ A11 of above reason can cause the hydrogen gas leakage in gas/water separater, please
check one by one.
(3 ) Water accumulated alarm fault
O If the small holes of gas/water separator is block. It can cause the gas/water separator
cannot let the water out.
@ Replace the gas/water separator, must ensure that the float can float up and down. If
the float is blocked, it can also block the small holes.

6.1
6.2
Operational Requirements A
This hydrogen generator cannot be used in sealed room .
Requirements for operational environments and conditions of the generators :
a. Temperature : 4"C- 40"C;
b. Humidity : <85Yo;
c. Power supply :220v--240V-50-60H2 or 99-l2lv-50-60H2;
d. The generators should be put horizontally near hydrogen-applied instruments
with their front boards facing operators for the convenience of operation;
e. There should be no obvious shaking and striking;
f. There should be no direct sunshine and open fire;
g. There should be no big dust , conducting particles , acid , alkali , and other
corrosive gases ;
h. Ventilation should be good ;
i. Ground connection of power supply should be good '*
6.3 The water tank of a generator should at first be filled with deionized or redistilled
water and then you should wait for five minutes prior to startup.
6.4 Requirements on pressure rising and how to deal with hydrogen produced when
the set pressure is reached without connecting hydrogen-applied equipment .
(1) During operation of the generators, operators are not allowed to look down at the
sealed top caps of the two-stage desiccators from above in order to prevent eyes and faces
from injuring .
(2) The generators cannot be operated when the output pressure is zero, and the minimum
9

OPERATION MANUAL FOR QL HYDROGEN GENERATORS
pressure for operation is 0.02 MPa. After start-up the pressure should be raised before it is
too long, or it will lead to internal ponding without normal draining of gas/water separator,
making the water level reach the maximum limit of alarming, resulting in stopping
electrolysis. When output of hydrogen reaches the maximum value, time of the operation
with zero of output pressgre should not be over 10 minutes. ( Generally speaking , after the
generators are delivered some internal resistance will be produced since the generators have
been equipped with two-stage desiccators and brass pipelines connecting hydrogen output
flow direction , and generally speaking , the internal resistance can reach the required limit of
the minimum pressure.)
(3) After start-up a generator is not allowed to be operated for a long time when the set
pressure is reached without connecting hydrogen-applied equipment, or it will damage the
core components of electrolytic cell.
6.5 The pressure of a hydrogen generator should be released to zero after it is shut
down.
The pressure can be released by loosing the nut of venting valve in front of the hydrogen
outlet on the backplate. The valve should be sealed agun after the pressure is released .
6.6 Requirements forWater Quality
As hard ions in unqualified water may cause sediment to block pores of electrodes, thus
resulting in scrapping of the electrodes, the electrical resistivity of water (deionized or
redistilled water ) in electrolysis should not be less than lMO/cm. All end-users should keep
it in mind, otherwise they should be responsible for all consequences.
6.7 Water Level Requirements for Water Tank
(1) The water level should be over two thirds of the volume of the water tank (volume of
water tank is 3.2L).
(2) Water should not be poured into the water tank violently and quickly to prevent water
from spilling out of the nylon overflow , under which there is an O ring sealing the housing
of the generator
to prevent water from entering the generator to damage the electric
components .
6.8 Requirements for changing water and cleaning water Tank
The water tank should be kept clean. Even the water is qualified at first, it will breed
microorganisms and become turbid when it is used for a long time, influencing output of the
hydrogen and the service life of electrolysis cell. The water tank, therefore, should be
emptied through the drain pipe every two or three months, and then washed several times (fill
the tank with a small quantity of new water and shake the generator lightly several times in
every direction) until discharged water becomes transparent without cottony things.
The drain pipe of water tank is attached to the backplate of the generator and can be freely
taken offand put in.
L0

OPERATION MANUAL FOR QL HYDROGEN GENERATORS
The small hole on the top cover of the water tank is used as oxygen discharging port,
therefore do not block it , and the top cover of the tank should not be changed at random.
6.9 During transportation of the generators, the water tanks should not store water so
as to prevent the water from spilling out to cause damages of the electrical components.
6.10 The electrolytic cells should not be short of water.
6.ll Requirements and Methods for Replacing Desiccant
The hydrogen generators manufactured by our company feature less internal resistance,
high electrolytic efficiency, and extremely small consumption for transforming electric
energy to heat energy, therefore the service life of desiccant (silica gel or molecular sieve) is
the longest among all hydrogen generators in the market up to now. If the phenomena
contrary to the above-mentioned occur or the color of desiccant changes in a large proportion,
it is possible that the generator has been in operation for a long time at full capacity
and with
a huge output . When you correct the above-mentioned improper operations and the color of
desiccant still changes very fast, the manufacturer should be informed for maintenance .
6.11.1 Introduction on Replacing Desiccant
The desiccator is located inside the right plate ( facing the front board look backward it is
on the right side ) equipped with a desiccant view port. The drying procedure is divided into
two steps.Two desiccant cartridges with blue silica gel is the first drying and one with
incarnadine molecular sieve as the secondary drying respectively.
The top caps covering the three desiccant cartridges protrude outside the top cover of the
generator, and arranged in a single row, with the same way for their replacements.
6.11.2 Requirements for replacing desiccant
(1) The desiccant should not be replaced during the operation ofthe generators
to prevent
high-pressure hydrogen from leaking and injuring people .
(2) Before desiccant is replaced , a generator must be shut down and the pressure must be
released prior to unsuewing and opening top cap of the purifier .
(3) The desiccant ( discolored silica gel or molecular sieve) will lose effectiveness after
water uptake to saturation, and should thus be replaced on time . When the height of
discolored silica gel is over half of that of the view port, it must be replaced I Or the water
content in hydrogen will be more than the standard , influencing the purity of generated
hydrogen . The molecular sieve for the secondary drying might be replaced once half a year
or a year provided that the silica gel for the first drying is replaced in time
(a) The generator, after desiccant replacement, should be in idle operation for several
minutes to wait for air to be emptied from the desiccant cartridges ,and hydrogen can only
be used when purity of generated hydrogen reachEs the standards '
6.1.3. Methods for Desiccant Replacements
lt

OPERATION MANUAL FOR QL HYDROGEN GENERATORS
Desiccant Regeneration
The silica gel should be baked under the temperature between 120 and 140 oC until its
color changes into blue completely .
@ fne molecular
sieve should
be baked under the temperature between 150 and 180 oC
for 2 hours.
The above-mentioned desiccant should be packed for use when it is dried and its
temperature decreases to below 50" C, and it will scald skin if its temperature is too
high . Too high temperature will scale the containers or skin of operators '
6.12 A generator must be shut down before it is repaired . During operation of a
generator , do not disassemble housings and other components of the generator in order
to avoid an electric shock.
6.13 A generator must be shut down by power cord disconnect with power source
before cartridge fuse is replaced Model of cartridge fuse used in QL-M150,
eL-M300,eL-M500 is F8AL250V, please do not make mistakes in using the cartridge
fuse so as to avoid fires .
7. Acceptance Check
7.1 Unpacking for the acceptance check
please check the generator are in good condition and make sure attached accessories are in
ready according to picking
list. If the generator is damaged during transportation,
please immediately contact with transport company and manufacturer for solution.
7.2 Operation for the acceptance check
7.2.1 The operational environment and conditions of the generators
should
meet the
requirements stipulated h 6 -2.
7.3.2 Open the top cap of the water tank on surface of the generator and remove the plug .
Fill water tank with deionized or redistilled water and water level in the tank should
be
between the Min. water limit line and Max. water limit line and finally screw the top cap.
The plug is used to prevent residual water from I eakage during traportation. Please
keep this plug in safty place in order to use it next time'
Since there is increasing oxygen gas produced through electrolyzation in water tank
and the plug has strong good seal function. If the plug is not removed during generator
works, the air pressure will be constantly increased in water tank and finally it will
make water tank burst. Thus please remove the plug before generator starts up'
12

OPERATION MANUAL FOR QL HYDROGEN GENERATORS
Operator should pay attention to this point.
There is a hole (3 mm in diameter) at top cap. It is used to release
oxygen gas.
Please keep this hole unblocked.
Caution: Before the generator is started up, please fill water at first and make
sure there is adequate water in electrolytic cell.
Caution : The generators must be filled with water prior and then start up ! Water
must be guaranteed for electrolytic cells !
7.3.3 Connect source of power supply and the generator by using power cord along with
the delivered generator , and insert the end of power cord in the socket ( Serial No. is 35 ) on
the back panel of the generator , and then insert the plug of power cord in the socket of the
power supply board . Ground connection of power supply must be good according to the
requirements of 6.3 of the operation manual. After connecting the power cord, turn on the
switch of power supply on the front panel. Both the power supply indicator and the
electrolysis indicator (green) will be on, and the number indicating the output of hydrogen
willbe increasing all the way to the maximum output of the generator.
7.3.4 When the nut for hydrogen outlet of the generator is sealed ( or screwed) securely,
output pressure will rise, and when the pressure reaches the preset value, the pressure control
system will take control to make the electrolytic current reduce to zero, and the number
indicating output flow rate will show falling to zero. The number indicating output flow rate
will show returning to the maximum of generated hydrogen when the above-mentioned nut is
unscrewed, which indicates the generator is in normal operation. After the acceptance check
is completed, the generator can be operated in accordance to the Operational Manual.
7.3.5 Connecting hydrogen-applied equipment
After acceptance check, at first shut down a generator when you are prepared to use it.
Produce the pipe ( a brass coil pipe with outer diameter of 3 mm , wall thickness of 0'5 mm
and length of 1,500 mm ) connecting hydrogen-applied equipment from an accessories bag
along with the generator . When a generator is delivered , the two ends of the pipe have been
equipped respectively with an international standard threaded nut of M8x1 and three O-rings
for sealing . Distance between each end of O-rings and that end of the brass pipe is 6-8mm .
The one end will connect
outlet port of a generator , and another end will connect a set of
hydrogen-applied equipment in the same way . If nozzles of hydrogen equipment are
measured in the British system , for example , chromatographs made by Shimadzu of Japan ,
Agilent and Varian of USA , whose sizes of nozzles are measured in the British system ,We
san agogssorizo relov artt nozzlas aooording to different requirernents of our customers and
will mark out on the accessories bags of nozzles .
13

OPERATION MANUAL FOR QL HYDROGEN GENERATORS
Insert the two ends of a connecting pipe into the relevant nozzles, and use a spanner
delivered along with the generator to seal the nuts and nozzles in cloclovise sense . Do not
overexert yourself in sealing the nuts prevent the O-rings losing elasticity , resulting in
influencing the sealing effect .
After hydrogen-applied equipment is connected , use soap suds to check the sealing for
leakage . If bubbles occur , the assemble should be readjusted until no leakage is found . The
same method should be used for checking leakage in sealing nuts of the other parts and
components .
