Roto Quick Coupling (10), Cooling Water Lines - W&H Roto Quick RQ-03 Instructions For Use Manual

Cooling water lines
ll Roto Quick couplings are equipped with a non-retraction valve which prevents contaminated cooling water
from being sucked back into the turbine and the turbine hose.
The non-retraction valve– is integrated in the cooling water supply system.
In the event of blocked or incorrectly routed cooling water lines, please contact an authorized W&H service
partner (see page 31).
The cooling water lines must not be cleaned with sharp objects!
(This could damage the sealing element and prevent the non-retraction valve from working.)
