Shut off 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.
Isolator / Check valve / Filter housing supplied 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 fixed 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.
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 overflow.
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 2000) and will need to be reset via the APP.

Fault Diagnosis
As with most electronic equipment re-setting the mixing valve by powering it down at
the mains, waiting a few seconds and powering it up again can often cure any issues.
Symptoms Probable Cause Possible Remedy
No water flow / will
not turn on
Product has entered an error
mode indicated by a flashing
“spanner” symbol
Refer to Error Log
Product in cleaning / disabled
mode
Use magnetic key to put back in normal
mode.
No power to the Digital Mixing
Valve
Check electrical connection and power
supply - Power cycle the digital mixer
(turn off and on again).
Inlet water supply isolators not
fully turned on Check and remedy.
Inlet water supply failure Check and remedy.
Inlet filters or check valves blocked Check and remedy.
Inlet check valves / flow regulators
installed the wrong way around Check and remedy.
Outlet spout, hose or handset
blocked Check and remedy.
Reversed inlet supplies Check and remedy.
Inlet water pressure too low Check specification.
“Blocking” time set Commission “Blocking” time using the
communication app.
