General

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

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.

Important Safety Information

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.

“ spanner ” symbol

Product in cleaning / disabled mode

Possible Remedy

Refer to Error Log

Insufficient quantity of stored hot water

Check and remedy.

Increase hot inlet water temperature to between 131°F and 149°F (55°C and 65°C), fefer to “ Specifications ”.

Hot water supply running out, increase storage capacity.


Outlet pipe run is too long


Temperature adjustment set too high

Possible Remedy

Check settings in “ RADA AP1 ”.

Power cycle the digital mixer (turn off and on again). Ensure inlet filters are clean.

Perform a cold flush using the Coms

App to flush debris from unit.

Contact Rada.


The product will make a mechanical noise during (and just after) normal operation


Water Hammer

Amplified acoustic noise from the

Digital Mixing Valve mechanism due to structure of the mounting


Ensure all pipework is securely fixed.

The type of wall or surface the appliance is fixed to will affect the perceived noise level; solid walls will provide a quieter operation.

Contact Rada.

Clean sensor window.

Infra Red sensors activated by reflective surfaces such as polished basins, Hi-Vis jackets and mirrors.

Direct sunlight or constant shadowing of the sensors to be reduced.

Contact Rada.

Replace seal and re-fit product.

Correctly engage product to manifold.


23

A flashing “spanner” symbol indicates the product has gone in to an error mode. If repeated errors are logged this MUST be diagnosed and corrected by a technician. The “RADA AP1” can be used to disable the valve until fault diagnosis can be made. Using the “RADA AP1”, navigate to the Health Check Page tile 12, to read the error log.

Note: The last 10 errors are logged in the units memory

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.

Alternatively navigate to the Health Check Page tile 9 of the “RADA AP1” and press

“Clear Valve Error” button to reset the valve.

Error Log

Over temperature at control

Over temperature warning

Over temperature at outlet

Probable Cause

Maintenance

Cleaning

Caution!

Risk of product damage. Many cleaners contain abrasive and chemical substances, and should not be used for cleaning stainless steel, enamel, plated or plastic fittings. These finishes should be cleaned using a mild washing up detergent or soap solution, rinsed and then wiped dry with a soft clean cloth.

Note: Run the tap for 30 seconds in order for self calibration to take place

Change the flow insert
