2 IMPORTANTPRE-INSTALLATIONNOTES
Connection to an interrupted power supply intended to stop electrical consumption in an unused facil-
ity, may adversely a󰀨ect this sensor product and is therefore not recommended.
Each time the power supply is reinstated the product briey enters reprogramming mode.
During reprogramming mode, any interaction (passive or active) with the product may alter the sensor
settings in respect to range and / or run duration.
No signicant savings will be achieved by connection to an interrupted supply. These products are in-
trinsically economical in terms of both water and electrical energy and will shut down in the event of a
sensor being obstructed.
SENSOR PROTECTIVE COVER
This product is supplied with the sensor lens covered over with a black-out material.
DO NOT REMOVE this lens cover until the product
installation has been completed & then wait for at least 20
seconds after powering-up.
The lens cover prevents the sensor from being unintentionally
reprogrammed during the powering up sequence.
MAINS ELECTRICAL POWER SUPPLY
Mains powered Sensor Operated Products must be connected to a (fused / switched)
continuous permanent power supply.
Don´t
remove, read
instruction 1st
DURING SETTING UP PROCEDURE AVOID HIGH VISIBILITY CLOTHING

2.1 Description
Markwik 21+ panel mounted mixers (demountable)
With xed or removable spout & Armitage Bioguard outlet
This manual covers the Markwik 21+ range of time ow operated, panel mounted, thermostatically
controlled mixers. These are designed to provide water at a preset temperature for hand washing.
The time ow controls allow operation of the ow without the user having to touch the mixer.
These products are tted with an Armitage Bioguard outlet which reduces the opportunity for bio lm
attachment and is lined with anti-microbial copper.
A hygiene ush (automatic) is an important optional feature of these products which can be enabled by
the installer or maintenance sta󰀨 using the optional remote programming unit. The hygiene ush is used
to combat periods of low usage of the product. The program monitors and permits the tting to be run
automatically if it hasn’t been used for a set time period. This feature ensures regular movement of water
preventing stagnation, thus combating bio lm growth and bacteria colonisation.
See section 12.7 for more details.
Two timed ow models are covered one with removable spout and one with xed spout
Flow starts when the user’s hand enters the detection zone and shuts o󰀨
after a pre-set time. The pre-set time can be adjusted. Traditionally the sensor is mounted to the right
of the tting, but it can be mounted to the left if necessary.
They are both intended to be installed on duct panel walls.
The panel thickness should be in the range 13 - 27 mm. Two holes, of diameter 30mm nominal and one
at 35mm nominal, will need to be cut in the panel at centres dened in Figures 1 & 2
The hot side of the mixer is insulated to ensure the body surface is maintained at a safe temperature
when the tting is in operation.
These mixing valves are supplied complete with integral isolating valves, strainers, check valves and
ow regulators. They have a built-in thermal shock feature, using the special tool provided, the maxi-
mum blend stop to be overridden up to the full hot water supply temperature in the system.
These Markwik 21+ products permit quick & easy removal of the mixer. The spout can also be removed
for cleaning, disinfection & maintenance purposes on mixer A6684AA.
Dry testing & protective caps
These products are delivered to our customers in a dry state. Water testing of these products at the
factory has been replaced by air testing, using clean dry ltered air. After testing, both inlets & the outlet
are tted with protective caps to prevent environment contamination entering the product during transit
