  • Page 9: Specification

    Specification Normal Operating Conditions are considered as: inlet dynamic pressures nominally balanced to within 10% of each other during flow. a differential of 15-35°C between the blend setting and either supply. daily usage of 1-6 hours. installation and usage environment not subject to extremes of temperature, unauthorised tampering or wilful abuse.
  • Page 10 Maximum Flow Rate: 120 l/min Flow Control Rada 320 mixing valves do not have integral flow control; appropriate provision must be made for this in the outlet pipework. This can be in the form of a stop-cock, mechanical timed-flow controller, solenoid or basin/bath tap. The device chosen must be non-concussive in operation.

  • Page 18 The maximum blend temperature obtainable by the user should be limited, to prevent accidental selection of a temperature which is too hot. All Rada Thermostatic mixing valves are fully performance tested individually and the maximum temperature is pre-set to approximately 43 C under ideal installation conditions at the factory.
  • Page 19 For Adjustable Temperature Remove the concealing cap, temperature knob and then the screw using the 3 mm hexagonal wrench (supplied). Remove the temperature knob and the hub. Rotate the spindle until required blend temperature is obtained at outlet point (clockwise = decrease temperature, anticlockwise = increase temperature).
  • Page 20 For Locked Temperature Remove the concealing cap, temperature knob and then the screw using the 3 mm hexagonal wrench (supplied). Remove the temperature knob and the hub. Rotate the spindle until required blend temperature is obtained at outlet point (clockwise = decrease temperature, anticlockwise = increase temperature).

    Commissioning Checks (Temperatures should always be recorded with a thermometer with proven accuracy). Check inlet pipework temperatures for correct function of checkvalves i.e. that hot water does not cross flow into the cold supply and vice versa. Check that the supply pressures are within the range of operating pressures for the valve.

  • Page 22: Troubleshooting

    Hot water in cold supply or vice versa Indicates check valve require maintenance, refer to Maintenance. Note! Some 320 variants are not supplied with checkvalves. Therefore, in-line checkvalves may require maintenance. These may be away from the product. Maximum blend temperature setting too hot or too cool a.

  • Page 23: Maintenance

    The maintenance of this product must be carried out in accordance with instructions given in this Manual, and must be conducted by designated, qualified and competent personnel. Rada products are precision-engineered and should give continued superior and safe performance, provided: - They are installed, commissioned, operated and maintained in accordance with the recommendations stated in this Product Manual.
  • Page 24 Performance Check Six Monthly Exercising the Thermostat: If the valve has not been in regular or recent use the thermostat should be exercised before any other checking. Where user adjustment of the blend temperature is available the exercising of the thermostat can be achieved as described in COMMISSIONING.

  • Page 26 Components are precision-made, so care must be taken while servicing to avoid damage. When ordering spare parts, please state product type, i.e. Rada 320 IC, and identify part name and number (refer to PARTS LIST). A Seal pack is available, containing all the seals that may be necessary for renewal during maintenance or servicing.
  • Page 27 Cartridges may only be cleaned by flushing through under a jet of clean water to remove debris. Do not descale. Descaling solution MUST not be used on any parts of the 320 valve. Cartridges are not serviceable, and must not be dismantled.
  • Page 28 Identify which is the hot inlet to the mixing valve body, and align the cartridge assembly accordingly. Note! There is a 'H' and 'C' marked on the cartridge. Make sure that the 'H' aligns with the hot inlet and that the 'C' aligns with the cold inlet. Align the cartridge guides with the slots in the body and carefully push the cartridge assembly back into the body, checking that the 2 cartridge inlet port seals remain in place.
