The
inflating system includes the inflation valves, and depending on the model
a foot or hand pump with its valve connector.
The Inflation Valves
:
The
inflation valves are plastic, therefore non-corrosive and double sealed
for safety. The valve is divided into two pieces, one is located on the
inner side of the buoyancy chamber. The other is screwed to the afore-mentioned
piece from the outside of the buoyancy chamber. This last piece is composed
of a one-way check valve, a diaphragm and a cap. This screw-on system
enables you to remove and replace a damaged valve very easily.

To
Inflate:
Make
sure the plunger in the centre of the valve is out. Push the end of the
bellows hose with the correct valve connector into place on the valve
as far as possible and turn clockwise until the valve connector locks
in place. Compress the bellows or hand pump by pumping gently and unhurriedly.
When inflated, screw the plastic cap onto the valve until it is fully
seated.

Warning
Never use
a gasoline service station or high compression pumps to
inflate
your boat. They could damage the buoyancy
collar or inflatable keel.
Air
tightness is obtained partly by means of the plunger one-way check valve
that is set in the base
of the valve insert; complete air-tightness
is ensured by the properly fitted valve cap.
Before
screwing on the cap, check that the valve is clean, free from sand,
weeds or other debris.
To deflate:
Remove
the cap and with your finger, push down the spring loaded plunger in the
centre of the valve. To deflate totally you may want to lock the plunger
down.
The Foot Pump
:
To inflate
your boat properly, the bottom part of the foot pump should lie flat on
the ground. Connect the valve connector appropriate for the valve. The
boat inflates quickly if you pump gently and unhurriedly. The top part
of the bellows must rise fully at each stroke. The supplied foot pump
has a capacity of 5lts. (1.32 gallon) The foot pump comes with two connections;
one for inflation the other for deflation.
The Hand Pump
, also called Cylindrical
pump:
To inflate
your boat, connect the valve connector appropriate for the valve. Put
the pump in an upright position and step onto the tongues, located at
the bottom of the pump. The hand pump is a double-action one. Each time
you lift or push the handle, 4lts. (1 gallon) of air will enter the buoyancy
chambers. The hand pump comes with two connections; one for inflation
the other for deflation
The Inflatable Keel
:
The
boat must be completely assembled when ready to inflate the keel. The
correct pressure of the keel is 0.20-0.25 bar (3-3.75 psi) in order to
obtain the correct outline of the boat and keel. (A pressure gauge is
not included with the boat)
The
Buoyancy Chambers
:
Depending
on the model you have chosen it will have three or more air chambers.
For specific information on your boat turn to the chapter on Specifications.
The more chambers it has, the safer it will be. Each chamber is divided
from the other by a special baffle system that keeps our multiple air
chambers completely sealed off from one another, while working to equalise
air pressure between compartments. It is advisable to inflate your boat
properly and check the pressure frequently. The pressure should be maintained
at 0.20 bar (3 psi) in the buoyancy chambers. (A pressure gauge is not
included with the boat)
A good
rule of thumb is: When you cannot depress the tube more than 1 cm (1/2
inch) with the pressure of your finger, you have then reached approximate
working pressure.
Important:
The correct way to inflate the main air chambers is by inflating the aft
chambers first, and then those towards the bow. When the inflatable keel
and the buoyancy chambers have been inflated, screw the cap on the valve
properly in order to secure final air-tightness. The buoyancy tubes must
be inflated to the recommended pressure otherwise the craft will perform
inefficiently. When the buoyancy tube cannot be depressed by finger pressure,
the approximate working pressure has been reached.
NOTICE
The
pressure of the boat fluctuates with change in temperature. Pressure
increases
after
prolonged exposure to sun, and falls when the boat is launched and when
in darkness.
Do not
worry about this. We have seen experienced people send boats over for
repair which
were in
excellent condition that either lost air due to a loose air valve, or
because of shifts in temperature.
Warning
Care
should be taken not to allow a boat which has been fully inflated
in the
cool of the morning to stand in direct
sunlight. Buoyancy pressure will quickly raise
with the
temperature and could strain or cause serious damage to the buoyancy
tube.
