Safety Warnings

The function of a Thermostatic Mixing Valve is to deliver water consistently at a pre-designated temperature.

Rada Thermostatic Mixing Valves are precision engineered to give continued superior and safe performance

provided:

1. They are installed, commissioned, operated and maintained in accordance with the recommendations

provided and accepted plumbing practices.

2. Periodic attention is given, as necessary, to maintain the product, the accessory fittings and the

plumbing system in good functional order.

In keeping with every other mechanical product, Rada Mixing Valves should not be considered as functionally

infallible and, as such will never totally replace the vigilance and attention of facility nursing/bathing or other

institutional supervisory or industrial safety staff.

Provided that they are installed, commissioned, operated and maintained, the risk of product failure and its

associated consequences, if not eliminated, are reduced to the minimum achievable.

*Rada 320 can accept temporary excursions above 185°F (85°C) and maintain control without sustaining internal

damage. (ASSE 1017 certification requires exposure to 200°F (93°C) for a period of 30 minutes). Prolonged

operation of the Mixing Valve at such elevated temperatures is not recommended.

** Under laboratory test conditions Rada 320 has displayed a repeatable capability to blend to within 5°F (2°C) of

each inlet supply temperature. 21°F (12°C) is the optimum published differential required to achieve full thermal

performance.
