DANGER
An excessive inflation of the boat leads to a false sense of security
and is dangerous for passengers. In fact, the slightest scratch in the tubes
could cause huge breaks. Remember that any increase in temperature
leads to a decrease in the mechanical resistance of the boat’s joints and to
significant increases of inner temperature. Therefore, the joints – if
submitted to excessive mechanical stress - may suddenly break.
We recommend to use a pressure gauge to check the pressure of your
boat, which must be 18 kPa (0,18 bar and approx. 180 cm of column of
water) in the external air chambers and 15 kPa (0,15 bar and approx. 150
of column of water) in the inner air chambers. The pressure fluctuates with
changes in temperature and increases after
prolonged exposure to sunlight. For instance, a
10 degree variation in the ambient temperature
will cause an increase or a decrease in the inner
pressure of 3,18 kPa. The nominal pressure will
go from 18 kPa to 21,8 kPa
NOTE
Use of the pressure gauge:
a) Insert the pressure gauge into each valve, starting from the grey
valves.
b) The pressure gauge must be inserted when the boat is only partially
inflated.
c) Insert the pressure gauge into the valve to measure the pressure.
Then, inflate the boat more and measure the pressure again. Go on
until you reach the proper pressure.
