Warning

To avoid the risk of property damage, serious injury or
death:

This kit should only be used by persons 12 years old
and up, and only under the supervision of adults who
have familiarized themselves with the safety measures
described in the kit. Keep small children and animals
away, as it contains small parts that could be
swallowed. Read the instructions before use and have
them ready for reference.

What you need:

Use the scissors to cut two lengths of 4cm(1.5 inches) of rubber tubing from the long rubber tubing
provided in the kit.
Place the red pin into one of the 4cm tubes, and the black pin into the other 4cm tube. Cut the
remaining long tube into two equal pieces.

Remove the screw from battery box cover using a screw
driver. Push and slide the cover to open the battery box.
DO NOT to touch the cables when you open the cover.
Place two AA batteries as indicated.
Push and slide the battery box cover to closed position
and screw tightly into place using screw driver.

Make sure the switch on the battery box is in the "off" position
before you place the batteries into the box.
WARNING: If the cable is short circuited the batteries inside could
become hot and potentially cause burns, melting of parts, or
create risk of fire.
Note: Battery’s energy may be consumed after 4-5 times of use.

AA Battery

Battery operation instructions:

1. The removing and inserting of batteries is to be
conducted by the adults only. Unscrew the screw holding
the battery pack’s cover in place using a screw driver. Once
the screw is removed open the battery pack and take out
the batteries using your fingers. Do not use a metal
object.When inserting the batteries make sure that you are
doing so with the correct polarity (the positive end of the
battery must match up with the “+” and the negative end of
the battery must match up with the “-” indicated on the
battery pack), close the battery pack and secure its cover by
tightening the screw with a screw driver.

2. Non-rechargeable batteries are not to be recharged.

3. Different types of batteries such as rechargable, alkline
and standard batteries or new and used batteries are not to
be mixed and should be used separately.

4. The battery pack cables are not to be inserted into an AC
socket.

5. The supply terminals of the battery pack are not to be
short-circuited.

6. The two spare red&black cables are not to be inserted
into an AC socket.

7. Exhausted batteries are to be removed from the battery pack.

ASSEMBLY GUIDE

AA batteries=2 Units Water=100ml

Connect the short tubes
completely onto the short H2/O2
intake nozzles located on the
lower sections of both "H2" and
"O2" sides of the fuel cell.

First add water up to the "0" line.
Place inner containers into outer cylinders minding that the gaps are not blocked by inner plastic
rims. Make sure the water is still level to the “0” line. If not, remove some water with the syringe.
Then connect the tubing to the inner containers. Make sure there is no air trapped inside the inner
containers and the water is level to the "0" line.

Procedure for repeated gas production (after step

Distilled water

14): Disconnect the small plugs from the tubes
connected to the nozzles on the reversible fuel cell.
This will allow water into the inner cylinders to replace
the gasses and reset water levels to “0” line. Re-insert
the plugs into the tubes and repeat electrolysis again.

Connect the pre-cut tubes firmly onto the
inner storage cylinders short nozzle,
connect the tubes opposite end to the upper
nozzles located on the upper positions of
both "H2" and "O2" sides of fuel cell shown
here. Make sure the tubes are connected
correctly to the corresponding sides of the
fuel cell.

For solar panel: remove the cables
connecting the solar panel to the fuel cell.
Turn the switch on the battery box to “off”
and remove the cables from the cable
sockets located on the fuel cell. Keep the
battery box switched to the "off" position
except during the time you are performing
electrolysis.

Connect the red and black
cables to the solar panel,
and connect the other
ends to the red and
black sockets on the
fuel cell.

ALTERNATE OPTION:

Connect the red cable from the
battery pack to the red socket on
the fuel cell and connect the black
cable to black socket.

Switch the battery pack to the "on"
position.

Electrolysis of water should begin with
oxygen and hydrogen being produced
and stored in each storage tank.
Wait until the bubbles in the hydrogen
tank start to escape from the inner
storage cylinder located in the H2
cylinder.
(Be patient, process can take 15–20min)

Remove the red and black
cables connected to the fuel

cell in "step 10".
Insert the banana plug cables from the
car’s motor into the red and black plugs on
the fuel cell.
Make sure the colors of the plugs and
cables are inserted into plug socket of the
same color as in "step 10".
The motor should begin to power the car
and cause it to start in motion. The
estimated driving time on one charge is
about 3 to 5 minutes.

HYDROCAR TECHNICAL SUPPORT

1. The water levels do not drop when the gas outlet tubes on both sides of the
fuel cell are unplugged.
Solution:

Check whether the holes on the wall of the inner cylinder are blocked. If so, turn
the inner cylinder until water enters the holes and fills up the inner cylinder.

2. The reversible fuel cell does not produce hydrogen and/or oxygen.
Solution:

a. Check whether the wires are appropriately connected, and whether there are
any loose connections. The fuel cell could be completely destroyed if the red
wire of the battery pack is connected to the black jack of the fuel cell.
b. Check whether the switch of the battery pack is in the “on” position.

3. The water electrolysis process slows down.
Solution:

a. Add water to the oxygen side of the fuel cell and wait for about 5 minutes.
b. Replace old AA batteries with new AA batteries inside the battery pack.

4. The car stops moving while there is still hydrogen left inside the tanks.
Solution:

a. Purge the gases and perform water electrolysis for 4-5 minutes. Unplug the
hydrogen gas outlet tube and oxygen gas tubes to purge the gases. Perform
water electrolysis again until the hydrogen tank is filled, and connect the motor
to the fuel cell. If the problem persists, go to the next step.
b. Let the water electrolysis process last about 10 minutes to consume the
residual water. To push water out of the fuel cell, purge the gases. Perform
water electrolysis once more until the hydrogen tank is filled, then connect the
motor to the fuel cell.

Note: Hydrogen fuel cells are consumables and have a life time of up to 2 years and we give
warranty for 1 year. You can buy replacement fuel cells from Horizon by placing online orders
