 Maintenance
For the installation of O-rings the general guidelines for O-ring assembly have to be taken
into account. Mainly the correct installation (e.g. position), cleanness and greasing with
GISMA-FETT EK2 have to be ensured.
In case, that the O-rings carrying assemblies are installed for more than 2 years to a structure
and then will be disassembled, we generally recommend to replace the O-rings.
We recommend changing the O-rings at latest after 5 years, if the O-rings are used as
directed.
For assemblies, which will only be installed once, our experience shows the estimated
lifetime may be double. For operating temperatures between +5°C to +40°C, longer lifetimes
can be expected.
Defective clamps to be replaced.
 Alignment
Put the plug onto the receptacle. Twist the connector until the keyway locks into place.
While tightening the locking sleeve with the one hand, simultaneously feed in the connector
with the other.
 Mating
After tightening the locking sleeve by hand, screw it into the receptacle fitting using
corresponding wrenches. If the locking sleeve is designed with a safety screw, tighten it. For
defined clamping torque refer to GISMA document “Torque overview”.
 Cathodic Protection
Stainless steel (1.4404/ 1.4571 comparable to 316L/316Ti), marine bronze (CW307G) or
titanium grade 5 diver mate connectors must be connected to the CP (Cathodic Protection)
system at all times. Super Duplex stainless steel connectors should be isolated from the CP
system to reduce the possibility of hydrogen embrittlement.
 Pressure testing
Series 10 plugs and receptacles are longitudinal watertight up to the specified pressure
range (see dimensional drawings). Every receptacles and terminated plug for underwater
applications will be pressure tested acc. Customer or GISMA specification.
Hybrid connectors with coaxial and fibre optic contacts have to be tested with protective
caps to prevent deposits from decreasing the connectors performance!
 Safety
Test connectors or free touchable connectors with metal shell must be connected to the
earth conductor.
