Product description
- O-rings
- Retention sleeve
- Spray regulation ring (for RQ-14, RQ-34)
- Water filter with resuction stop
All Quick couplings are equipped with a non-retraction valve which prevents
contaminated cooling water from being sucked back into the turbine and the
supply 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 45).
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.)
Operation
Connecting the Quick coupling
- Connect the Quick coupling to the supply hose.
- Firmly tighten the union nut of the supply hose by hand in a clockwise direction to ensure there are no leaks.
Verify full engagement.
Check the leak tightness.
This method of assembly provides a connection for drive air, chip air, return
air, water.
Possible variants with electricity: RQ-24, RQ-34 or with light: RA-24, RA-25.
Disconnecting the Quick coupling
- Unscrew the union nut of the supply hose by hand in an anticlockwise direction.
- Carefully remove the Quick coupling from the supply hose.
Checking the Quick coupling for leaks
Push an appropriate air driven medical product onto the Quick coupling.
Activate the medical device, or if possible just activate the spray water only.
No water should leak between the Quick coupling and the air driven medical product, and the coupling and the supply hose.
Changing air driven products
