PRE-INSTALLATION INFO PACk CONTENTS
TUBULAR/QUADRAT SOAP DISPENSER
Familiarize yourself with the part names and ensure that all the parts are included in
your package.
Check contents
Separate all parts from the packaging and check each part with the “Pack contents”
section.
Make sure all parts are accounted for before discarding any packaging material.
If any parts are missing, do not attempt to install your touch free soap dispenser until you
obtain the missing parts.
Warnings
Do not install the system facing a mirror or any other electronic system operated by an
infra-red sensor.
To prevent reflection problems, it is recommended to keep a minimum distance of
 mm between the soap dispenser and any other objects.
Liquid soap dispensers, with proper care, will provide long term trouble free service.
Quality liquid soap of recommended viscosity and pH levels are the main factors for
smooth operation of your dispenser. If needed, use a viscometer to verify the viscosity
of your soap to ensure maximum benet. The recommended range for liquid soap
viscosity is  cPs. Thicker liquid soap flows slower and inhibits the pump valve,
causing strain and damage.
Liquid soap dispensers are suitable for use with any generic liquid soap of the correct
viscosity and pH. The pH level of all soap used in our liquid soap dispensers should be
between . to .. Lower levels will cause corrosion to the metal dispenser and even the
rubber and plastic components. Higher pH levels will cause swelling to rubber parts and
degradation of plastic components over time.
IMPORTANT: Keep in mind that when using the faucet installed next to the soap
dispenser, the user hands should not interfere with the soap dispenser sensor
detection area.

through the soap dispenser
base, and cut the temporary soap
dispenser base cover.
Fix the soap dispenser spout by
inserting the nipple into the soap
dispenser base and tighten the
screw.
Pull the four way connector and the
power supply connector out of the
soap dispenser base, and lead it
through the corrugated tube.
INSTALLATION
STEP 1 – INSTALLINg THE MF SOAP DISPENSER

Cut an adequate opening in the wall for
the dimensions of the soap dispenser
base (where you want to install the
spout) and the corrugated tube.

the set screw.
SET SCREW

Mount the soap dispenser base into the
opening in the wall and secure it using
the two anchors provided in the package.
Important: The soap dispenser base
should be installed so that the outside
surface of the nished wall falls between
the minimum and maximum lines marked
at the base.
Assemble the temporary protective soap
dispenser base cover.

Assemble the corrugated tube to the

MAINTENANCE
Care and cleaning of chrome and special nishes
DO NOT use steel wool or cleansing agents containing alcohol, acid, abrasives, or the like.
Use of any prohibited cleaning or maintenance products or substances could damage the
surface of the soap dispenser. For surface cleaning use ONLY soap and water, then wipe
dry with a clean cloth or towel. When cleaning bathroom tiles, the soap dispenser should
be protected from any splattering of harsh cleansers.
Disassemble of the soap pipe from the pump
The soap pipe can be disconnected from the soap pump by a simple slide & pull action.
The sliding ring of the quick connection xation nipple on the pump should be pulled
down. It releases the open end of the soap pipe which can then be easily pulled out.
Clean the soap tank
Clean out the tank prior to rell by flushing warm water through the hoses and pump until
clean water is released from the spout. TIP: Keeping a spare tank will enable this process
to be completed in a speedy and hygienic manner with minimal downtime.
