Standard product features

Rada Exact-3:

A ½" exposed thermostatic shower control incorporating a Radatherm service-free cartridge, pre-set maximum temperature stop, check valves and filters. Units are TMV3 approved for high and low pressure applications. The Rada Exact-3 is designed for fixing on a vertical wall surface using exposed pipework. The product can also be used with a rising outlet when fixed to Rada er-s 310 kit or VR145 and Rada riser.

Rada Exact-3 ev:

Identical specification to the Rada Exact-3 but supplied with a Mira Response exposed variable shower fittings.

Connections:

  • Inlet - 15 mm compression/½" BSP male connections to accept rising, falling or back inlet supplies.
  • Outlet - 15 mm compression/½" BSP external union.

Operation:

The top lever controls the temperature, whilst the bottom lever controls the flow.

The temperature controls allow the user to select the required temperature within the range available. An integral temperature stop limits the maximum temperature to a pre-set level and can only be re-set by an authorised person (alternatively, the temperature lever can be locked in position after the desired temperature has been selected).

Temperature range:

The maximum temperature that can be selected is set at approximately 43°C, this can be reset on site where required.

  • Minimum temperature differential, blend to either supply is 12°C.
  • Optimum thermostatic control range of mixer: 35°C to 45°C.
  • Minimum cold water supply temperature: 1°C.
  • Maximum hot water supply temperature: 85°C.

Note: The mixing valve can accept temporary temperature excursions above 85°C without damage, however, operation of the mixing valve at such elevated temperatures is not recommended. For reasons of general safety, hot water storage temperatures should ideally be maintained at between 60°C and 65°C where serving ablutionary requirements.

Pressure/ Flow rates:

  • Minimum dynamic supply pressure: 0.15 bar.
  • Maximum dynamic supply pressure: 5.0 bar.
  • Minimum flow rate: 3 litres/minute at mid blend.
  • Maximum flow rate: 35 litres/minute at mid blend (which equates to a maximum pressure loss of 1.9 bar).
  • Maximum pressure loss ratio: 10:1 (in favour of either supply).
  • Maximum static pressure: 10 bar.

Materials:

  • Body: DZR brass and chrome plated.
  • Temperature and flow control knobs: Zinc alloy and chrome plated.
  • Lever controls and trims: Engineering plastic.

Accessories:

  • Rada er-s 310 kit.
  • VR145 and Rada riser.
