Inflation/deflation boat tube.
The inflation valve (see Fig.15) has two positions of sliding part A
corresponding to its two conditions (modes):
– sliding part A is withdrawn - operation condition of the valve
(compartment air filling mode);
– sliding part A is recessed - valve in condition "OPEN" (compartment
air discharge mode).
In order to switch the valve over from one condition to another, just
press sliding part A with your finger to turn it by 90 degrees in any direction
until it is fixed.
Prior to begin the compartment filling process set all valves in the
operating condition. On completion of filling close the valves with bonnets
B (rotate them clockwise).
In order to discharge air from the compartments, open the valves (by
counterclockwise rotation) and switch the valves over into condition "OPEN".
Board air chambers are hermetical if they keep own form during 8 hours. In this case:
– primary pressure has to be nominal;
– input valves openings have to be tightly closed by caps.
The rated pressure value is 0.15 bar (2.2 psi).
If the tube pressure more than nominal, deflate the compartments slightly. Boat exploitation
with board pressure more than nominal decreases boat service life.
Do not use compressors and/or other types of inflating equipments not approved by the boat builder.
Check tube pressure before every navigation.
