Roth diving tank
The tank consists of:
- steel cylinder,
- twin outlet valve,
-a PVC boot,
- carry handle,
- protective net.
Boot and handle
The PVC boot is tailored to fit the diameter of the bottles and allows them to stay in a vertical position. An opening is provided at the bottom to evacuate residual water and to make it easier to remove.
The carry handle is made of two parts enabling it to be assembled and removed without having to unscrew the valve.
Maintenance
It is forbidden to carry out repairs by welding, riveting or drilling the cylinder or any operations involving removal of material or significant rises in temperature of the cylinder (maximum 300 °C).
Routine maintenance
We recommend rinsing the cylinder daily with fresh water without forgetting the bottom (hole provided in the PVC boot;this drains seawater, removes sand and avoids abrasion of the paint and premature corrosion).Immediately touch up areas of chipped paint due to impact or abrasion.
It is forbidden to carry out repairs by welding, riveting or drilling the cylinder or any operations involving removal of material or significant rises in temperature.
Periodical maintenance
This tank is subject to regular periodic inspections as required by the legislation in force in the country of use. These checks must only be performed by qualified establishments or persons.
In France, the decree of 15 March 2000 makes annual inspections by TIV compulsory, and requalification after 5 to 2 years.
Storage
Before prolonged storage, it is advisable to perform the maintenance actions outlined above as well as rinsing with fresh water and thoroughly drying the inside of the cylinder. Moreover, it is strongly recommended:
-to store the cylinder upright in a temperate, clean and dry place,
-to maintain low residual pressure inside the cylinder in order to remove any dust and condensation that may have entered through the valve opening.
Recommendations 1/2
Never inflate a lifting bag with bare valve gear (without a regulator).
- Never leave a cylinder empty with the valve open.
- Never leave cylinder exposed to spray and waves or in the water at the bottom of a boat.
Recommendations 2/2
- Keep residual air pressure in the cylinder in order to drain any water that has entered by the valve opening. If the cylinder was fully emptied when diving, leave the regulator in place until it is under shelter.
-Never empty cylinders too quickly in order to prevent the valve gear from frosting and significant condensation inside the cylinder.
Dimensions
Height without valve:52 cm.
Height with valve: 68 cm.
