not repairable. In case of its defect it is replaced. Replacement may only be performed by an employee of the
authorized service company.
It is necessary to visually check mechanical wear of the end piece and check its tightness by using a
foaming agent at least
once a month.
The damaged filling end piece must be immediately replaced!
Replacement may only be performed by an employee of the authorized service company.
We recommend lubricating the fastening mechanism of the end piece neck with silicon oil
once per 3
months.
This activity may be performed by the fuel station attendant.
It is necessary to check conductivity of the breakaway coupling‐hose‐end piece set at least
once per 6
months
– i.e. resistance between the end of the filling end piece and the central grounding terminal of
the dispenser must be lower than 1 MΩ (testing voltage of 500V) in a pressurized operating condition
and without pressure.

SAFETY DISCONNECTING COUPLING (BREAKAWAY COUPLING)
The safety disconnecting coupling is intended for disconnecting the filling hose in case of its extreme tensile
stress. It is fitted with two valves that prevent gas from leaking from both ends of the
breakaway coupling after its disconnecting. Breakaway couplings used at OCEAN CNG
dispensers allow up to 100 repetitive disconnections and connections. Connection may
only be performed by an employee of the authorized service company by using a special
tool.
It is necessary to visually check mechanical wear of the breakaway coupling and check its tightness by
using a foaming agent at least
once a month.
The damaged breakaway coupling must be immediately
replaced! Replacement may only be performed by an employee of the authorized service company.
