•the actual voltage, current and power drawn during a gas-production
operation. See Figure 4 on page 19.
The power dial varies the amount of current (and thus power) applied
during an operation. This determines the amount of gas produced and
also the amount of heat generated during the production. The higher the
current, the more gas (and heat) that is produced.
For optimal use, the current should be set 20.10 amps. The voltage
cannot be changed.
The button below the power dial starts (and stops) the gas-production
operation.

6. Commissioning
Before you begin
To prepare the QB5 for first-time use, you will need:
•distilled or demineralised water: at least 2 litres (1 litre for the initial setup and 1 litre
for first-time use)
•a funnel
•the dehumidifier canister shipped in the accessories box.
Steps
Numbers in square brackets refer to the components labelled in Figure 1 on page 12.
1. Remove the water tank cap [5].
2. With the assistance of the funnel, fill the water tank [6] with 1 litre of distilled or
demineralised water. Use the dip-stick attached to the water tank cap to check that
the level is correct.
Do not over-fill the water tank.
3. Remove the dehumidifier canister from its protective bag inside the accessories box

7. O p e r a t i o n
Keep the QB5 upright at all times so as to prevent fluid from passing into the
gas collection points.
7.1 Before you begin
7.1.1 Check the water level
WARNING: If the QB5 is operated without water or is allowed to run dry, the
electrolyte cell will be damaged and the warranty rendered void. Replacing the
cell will be at the owner’s expense. DO NOT LET THE QB5 RUN DRY.
Although checking the water level is not necessary with every operation, it should be
done regularly. If running the QB5 at the recommended maximum setting—20.1
amps—the water level in the tank should be checked at least every 15–20 hours of use.
For example, if the QB5 is used for 5 hours every day, you should check the water level
every 3–4 days.
1. Remove the cap from the water tank
2. Check the water level and add water if necessary. The recommended maximum
volume of water is 1 litre.
Do not over-fill the water tank.
3. Refit the cap.

QB5: Operation Manual 18
7.1.2 Attach a hose
Three hoses are supplied with the QB5:
•a diffusion stone hose
•an auxiliary general hose for transferring gas to an auxiliary device of the user’s
choosing.
•a tee piece hose.
Attach the appropriate hose to the gas discharge port (Figure 3).

7.2 Gas production
WARNING: : Before using the QB5, ensure that it is located in a well-ventilated
area and that the ventilation ports—item 15 on page 12—are not obstructed.
1. Check that the AC power cable is connected to a mains outlet and that the power is
turned on.
2. Press the main power button. Labelled “ON/OFF” in Figure 4 below.
After a short moment during which the QB5 is calibrated, the display shows that the
QB5 is in stand-by mode (Figure 4).
The maximum voltage and maximum current values are displayed across the top of the
display (6.5 volts and 20.10 amps respectively in Figure 4). The maximum voltage value
is pre-set and cannot be changed. The maximum current value can be changed.
Increasing the current increases the power, which increases the amount of gas
that is produced. However, for general application we recommend that the
maximum current value remain at 20.10 amps. Regular use of the QB5 at a higher
current may affect the lifetime of the electrolysis cell. If used at recommended
settings—and serviced at the recommended intervals: see chapter 8—the QB5 is
expected to have a lifetime exceeding 10,000 hours.
During gas production, the actual values for voltage (green), current (yellow) and power
(purple) are shown on the next three rows of the display. Figure 5 (page 20) shows
sample values during a gas production run.

3. If you want to change the maximum current:
a. Press the button. Labelled Bin Figure 6 below.
b. Turn the power dial—labelled E—clockwise to increase the maximum current
or anticlockwise to decrease the maximum current.
c. To set a more precise value, push the power dial in. Turning the power dial will
now increase or decrease the value in the first decimal place (moving the
value, for example, from 5.00 to 5.10). You can set a value that is even more
precise by pushing the power dial in once again. Turning the power dial will
now increase or decrease the value in the second decimal place (moving the
value, for example, from 5.10 to 5.15). Push the power dial in again to be able
once again to adjust the first digit.
d. With the required maximum current set, press the button twice. The
button is labelled Din Figure 6 below. The value specified appears at the top
right of the display.
