General
Shut o󰀨 the main water and electrical supply.
Observe all local plumbing and building codes.
The Rada MX1 is a type 1, electronic, electrically operated, independently mounted valve. It is
intended for surface mounting and is for connection to the mains water supply.
Inlet Unit. Comprising of Filter / Flow Regulator / Check valve / Isolation is an integral component
of the tap, failing to install will invalidate the product’s warranty.
The Rada MX1 must only be supplied from the power adaptor provided.
The power adaptor must be connected to the xed wiring of the electrical supply via a switched
3A fused spur.
If the power adaptor supply cord is damaged the power adapter must be replaced by a competent
person.
The Rada MX1 has been certied for use in UK Healthcare premises as a TMV3 approved valve,
the approved designations of use are HP-WE.
For Healthcare installations refer to the TMV3 Requirements Manual which is available to view
or download from our website www.radacontrols.com.
Where chlorine disinfection is practised, DO NOT exceed a chlorine concentration of 50 mg/l (ppm)
in water, per one hour dwell time. Such procedures must be conducted strictly in accordance
with the information supplied with the disinfectant and with all relevant Guidelines/Approved
Codes of Practice.
The use of the word ‘failsafe’ to describe the function of any thermostatic mixing valve is both
incorrect and misleading. In keeping with every other mechanism it cannot be considered as
being functionally infallible.
Malfunction of thermostatic mixing valves can be detected by the use of proper temperature
checking and maintenance routines.
Certain types of system can result in the thermostatic mixing valve having excessive ‘dead-legs’
of pipework. Such systems can disguise the onset of thermostatic mixing valve malfunction.
Ultimately, the user must exercise due diligence to ensure that the delivery of warm water is at
a stable, safe temperature.
Make sure that the water delivery does not cause splashing or overow.
Allow su󰀩cient projection into the basin by ensuring the tap is mounted close enough to the vessel.
Important Safety Information
Make sure that the Rada MX1 is installed by a competent installer.
The product commissioning, clock (date/time) and tap set up can only be done in conjunction
with the “RADA AP1” available from the Apple APP store. Time and date setting is critical to
ensure data reporting is correct.
Note: Clock settings are lost after a period of 24hrs without mains power. When power is
restored clock settings return to factory default (1st February 2016) and will need to be reset
via the APP. Minimum charge time required for settings to be successfully set is 1 hour.

Inlet Unit - Important
Failing to install the inlet units will cause product damage, invalidate the product’s
warranty and the product will no longer be TMV3 compliant.
The inlet unit is an integral component of the product consisting of a Filter / Flow
Regulator/ Check valve / Isolator.
The units are specic to hot and cold supplies, identied by a red / blue indices.
Flow direction is critical and is identied by the arrow on the unit’s body.
Filter contained in the unit is a ne 150 micron stainless steel mesh.
The ow regulators are included to the ensure the tap delivers a uniform ow and must
remain in situ for correct performance.

Installation Requirements
The Rada MX1 basin mounted tap can be installed with either exible tails or rigid
pipes. Refer to the installation schematics below:
Installation with Rigid Pipes
Inlet Unit
Site in a location to
aid easy isolation and
servicing
Allow sufficient projection into
the basin by ensuring the tap is
mounted close enough to the
vessel.
Care should be taken to mount the
tap over the water catchment area
to avoid any drips on to the counter
top during tap shut down.
