1. Introduction

6
Intended use
Connection piece for the transmission of media (air, water, electricity and light)
between the supply hose of the dental unit and the air drives.
Misuse can damage the Roto Quick coupling and involves risk and danger to user and third parties.
Production according to EU directive
The Roto Quick coupling is a medical product according to the EU directive 93/42/EEC.

7
Skilled application
The Roto Quick coupling is intended only for skilled application in dentistry according to its purpose of use in compliance
with the valid health and safety at work regulations and the valid accident prevention regulations as well as in compliance
with these Instructions for use. The Roto Quick coupling should be prepared for use and maintained by staff who have been
trained in procedures for infection control, personal safety and patient safety. Improper use, (e.g. through poor hygienic
maintenance), noncompliance with our instructions or the use of accessories and spare parts which are not approved by
W&H, invalidates all claims under warranty and any other claims.
Service
In case of service or repair contact an authorized W&H service partner (see Page 31).
Service and maintenance work must only be carried out by an authorized W&H service partner.

2. Before use – Safety notes
> The operation of the Roto Quick coupling with light is permitted only on dental units which correspond to the
standards IEC 60601-1 (EN 60601-1) and IEC 60601-1-2 (EN 60601-1-2) and satisfy the following
requirements to be guaranteed by the system assembler:
> Double insulation for the highest expected supply voltage must be provided between the primary and
secondary power circuits.
> Double insulation for the highest expected secondary voltage must be provided between the secondary
voltage and earth (PE).
> The secondary voltage must be limited to a maximum of 3.3 V AC/DC.
> The leakage currents of the applied part must be kept.
> The secondary circuits must be protected against short circuits and overloads.

Hygienic maintenance prior to initial use
The Roto Quick coupling is in a clean condition and sealed in PE-film when delivered.
Sterilize the Roto Quick coupling.
> Sterilization Page 24
9
> The user is not allowed to touch the ring contacts and the patient at the same time.
> Only use supply hoses which comply with EN ISO 916 .
> Always ensure that the correct operating conditions exist and that the coolant is working properly.
> As cooling air, only use air which has been processed by dental compressors and which is filtered,
free of oil and cooled.
> Before using the coupling, always check it for damage and loose parts.

3. Product description
➊O-rings
➋Retention sleeve
➌Spray regulation ring (for RQ-14, RQ-34)

11
Cooling water lines
All 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.)

12
➊Connect the Roto Quick coupling to the turbine hose.
➋Firmly tighten the union nut of the turbine hose by hand in
a clockwise direction to ensure there are no leaks.
. Operation – Connecting the Roto Quick coupling
This method of assembly provides a connection for drive air, chip air, water and return air (only for RM).

13
➊Unscrew the union nut of the turbine hose by hand
in an anticlockwise direction.
➋Carefully remove the Roto Quick coupling from
the turbine hose.
Operation – Disconnecting the Roto Quick coupling

14
Checking the Roto Quick coupling for leaks
> Check for leaks between the Roto Quick coupling and turbine hose.
> Block the water outlet on the tip of the Roto Quick coupling using a piece of rubber or leather.
> Turn on the spray water. After being blocked for 10 seconds, no water must escape between the coupling and turbine
hose or at the spray regulator.
> If you observe problems (e. g. vibrations, unusual noise and/or leaks), stop the Roto Quick coupling immediately and
contact an authorized W&H service partner (see Page 31).

15
> Observe the instructions in the relevant instructions for use.
> Only connect air driven instruments with Roto Quick connections to the Roto Quick coupling.
The user accepts sole responsibility if other air driven instruments are used.
We accept no liability in such cases.
Operation – Changing air driven instruments

16
> Attach the air driven instrument onto the Roto Quick coupling until it audibly engages.
> Pull axially along the Roto Quick coupling to check that the air driven instrument is securely attached.
> Pull the retention sleeve of the Roto Quick coupling back.
> To disconnect the air driven instrument, pull it off in axial direction.
Operation – Changing air driven instruments
Never connect or disconnect the air driven instrument while the system is running!

17
Regulating the spray water
For Roto Quick couplings RQ-14 and RQ-34: Adjustment directly at the spray adjuster ring or at the adjustable valves of the
unit. Roto Quick couplings RQ-03, RQ-04 and RQ-24 can only be adjusted at the unit.
Minimum spray flow:
Line marking on the spray adjuster ring and point on the retention sleeve correspond with each other.
Maximum spray flow: Turn the spray adjuster ring to the right or left.
The water flow can only be varied using this spray adjuster ring. It cannot be stopped completely.

18
Test run
> Connect the Roto Quick coupling to the turbine hose.
> Attach the air driven instrument onto the Roto Quick coupling until it audibly engages.
> Start the air driven instrument.
> If you observe problems (e. g. vibrations, unusual noise and/or leaks), stop the Roto Quick coupling immediately and
contact an authorized W&H service partner (see Page 31).

19
➊Press the O-ring firmly together with your thumb and index
finger until it forms a loop.
➋Pull off the O-ring.
➌Slide the new O-ring back on.
Operation – Changing O-rings
Immediately replace any damaged or leaking O-rings.
Never use sharp tools!

5. Hygienic maintenance
> Follow your country-specific directives, standards and guidelines for cleaning, disinfection and sterilization.
> Wear protective clothing.
> Remove the Roto Quick coupling from the turbine hose.
> Clean and disinfect the Roto Quick coupling immediately after every treatment.
> The Roto Quick coupling is sterilizable
> Manual internal and external cleaning is to be carried out before each sterilization.
