Operating Notes - Thames & Kosmos AIR Plus Water Power Experiment Manual

Refer back to these notes when you are
using the models.
2. NOTES FOR OPERATION:
• Check to ensure that all of the hoses
are fixed to the correct positions before
pumping.
• Check to ensure that the air+water tank is
screwed to the end (Fig. 15). The air+water
tank should be half-filled with water
and thus half-filled with air, but you can
experiment with different fill levels.
• Check to ensure that the switch lever is
set to the middle of the switch (i.e. in the
closed position, as Fig. 16 shows) before
pumping, so that the pumped air and
water can't escape.
• Close the switch lever tightly so that air
and water cannot leak out. It may take a
decent amount of force to move the lever.
• Move the pump from the model to the
tabletop whenever you pump it, and put it
back after you finish pumping (Fig. 17).
• About ten pumps are needed to start
pushing water from the water storage
tank into the pressurized air+water tank.
Hold the pump handle up for two or three
seconds before you push it down again so
that the most water can be driven into the
pump cylinder during each pump (Fig. 18).
• Pump no more or less than 50 times.
If you pump it more than 50 times, the
basic parts might come under too much
pressure and become damaged. On the
contrary, if you pump it less than 50 times,
the power might be too weak to lead to
smooth operation. The more air you pump
into the tank, the higher the air pressure
will be, and the more energy is stored.
• Don't pull off any of the hoses — either
during operation or before all the water
returns to the water storage tank.
Otherwise, the water stream could spurt
out of the hose and might hurt you or
make a mess.
• If a hose becomes disconnected at any
time during operation, turn off the switch
by shifting the switch level back to the
middle to stop the spray of water, and
wipe the hose end and nozzle dry before
reattaching.
• Use the one-way switch to release the air
and water remaining in the pressurized
air+water tank before you put the model
away.
