commissioning
operation
Adjusting the soap dispensing volume:
1. Switch on the power supply at the fused spur or socket.
2. Turn on the pump by turning the dispense dial clockwise.
3. Depress and hold the ‘Prime’ button until soap is dispensed.
4. Activate the dispenser by placing your hand underneath the sensor to check
the volume of the soap that is dispensed from the nozzle.
5. The volume of soap dispenses can be adjusted by turning the ‘Dispense’ dial
clockwise to increase the soap volume, or anticlockwise to reduce the soap
volume.
+ The user places their hands within detection range of the sensor to activate the soap
dispenser.
+ The motor will start and soap is dispensed onto the user’s hands.
+ The motor will stop when the user’s hands are removed from the detection range.
IMPORTANT
The dispenser is only to be used with a compatible foam soap, with a viscosity of less
than 10cPs. It is not suitable for use with liquid or pearl soap, alcohol gels or hand
sanitisers.

TSL.420 MANUAL 14
cleaning
+ Take extra care when cleaning decorative surfaces.
+ For surface cleaning of the tap use ONLY soap and water, then wipe dry with a
clean cloth or towel.
+ DO NOT use steel wool or cleaning agents containing alcohol, acid, abrasives or
the like.
+ Use of any prohibited cleaning or maintenance products or substances could
damage the surface of the tap.
+ When cleaning bathroom tiles, the taps should be protected from any splattering
of harsh cleansers.
All gradesof stainless steel will stain or discolour if due care and attention is not taken.
The surface must be regularly cleaned to ensure a long service life of the tap.
Use a soft cloth or sponge with a mild solution of soapy water as part of the regular
washroom janitorial routine. Do not use abrasive or cream cleaners as these will
damage the surface finish.
If further information is required, contact The Splash Lab technical team for more
detailed stainless steel care guidelines.
soap
A good quality foam soap of viscosity <10 cPs units should be used. Hand cleaners
containing abrasive particles should not be used as this will cause damage to the pump
mechanism. The dispenser mechanism is not compatible with alcohol gels or
hand sanitisers.

maintenance
+ The soap dispenser should be serviced on a regular basis to ensure long service life
of the unit.
+ Isolate the unit from the power supply before any servicing or maintenance work is
carried out.
+ The dispenser should be activated at least once a day to ensure that soap does not
congeal in the pipework.
refilling
Single feed reservoir
1. Unscrew the reservoir from the connector cap.
2. Fill the reservoir with foam soap of viscosity in the range <10 cPs.
3. Screw reservoir onto the connector,
4. Press and hold the prime button until soap is dispensed from the spout.
Multi-feed pipe system
1. Remove the support clips and pipes from the neck of the soap reservoir,
2. Fill reservoir with soap until desired level is reached.
3. Replace the feed pipes in the reservoir, ensuring the ends of the soap pipes
are beneath the surface of the soap.
4. Alternatively, the feed pipes can be inserted into a replacement container of
soap.
5. Press and hold the prime button until soap is dispensed from the spout
The level of soap in the reservoirs should be checked regularly to ensure the soap feed
pipes are always dipped into the soap. If it does happen that the soap level is allowed
to fall below the minimum required, there will be an airlock introduced into the pipe,
which will then need to be re-primed. Priming of the system is achieved by pressing the
prime button on the pump unit.
