12.3.3 CHECKING HOSES
Check all hoses by bending and pulling them, and by making a note of any damage, cracks, discoloring
and changes in hardness.
If the equipment is defective or damaged, it must be repaired by a service technician approved by
Interspiro.
WARNING! A pressure drop caused by a rupture on a dry-suit hose is just as great as any caused by a rupture
in the breathing hose. For this reason, be careful when carrying out the inspection!
12.3.4 CHECKING O-RINGS
O-rings that have been exposed to sunlight, salt water, chemicals (including mild detergents) and ozone will
age and subsequently become defective.
1
. Check all visible O-rings.
2. Cracked and damaged O-rings must be replaced.
3. All O-rings in this user manual should be lubricated with Interspiro's special lubricant 331 900 269.
The user may only personally replace the O-rings described in Section 12.4 “Repairs” in this user manual.
Other defective or damaged parts must be repaired by a service technician approved by Interspiro.
12.3.5 CHECKING THE ANTI-FREEZING CAPS
A leaking anti-freezing cap increases the risk of freezing and causes the regulator to function less
effectively.
WARNING! Oxide layers and salt deposits in the regulator can stop the air supply. If the regulator has been
exposed to water inside the regulator housing for a long time, the regulator piston can jam or stick. If a fault
of this type is suspected, the regulator must be repaired a service technician approved by Interspiro.
It is important to make sure that the anti-freezing caps are internally free of water. If they contain water, the
unit must be inspected and, if necessary, serviced by a service technician approved by Interspiro.
Regular inspection should be carried out on a dry, clean apparatus in a dry, clean and, to the extent pos-
sible, cold-resistant environment. Inspection should always be carried out before the equipment is placed
in storage, but it can also be carried out during air lling, and at least once a week.
During regular inspection, the anti-freezing unit must be disassembled and the anti-freezing caps must be
checked for internal occurrence of water, dirt and damage; the O-rings must also be checked for dirt and
damage. Dirty parts must be cleaned and wet parts must be dried. All parts must be dry before they are
assembled again.
Always rinse with fresh water. The anti-freezing unit should not be disassembled when the apparatus is
used regularly and does not have time to dry.
