Caution! High water pressures may deliver a volume and spray force which is injurious to the
user. Check with fixture manufacturer or regulate water pressures within acceptable range.
Warning! Correct on site commissioning of Rada 32E is critical.
Warning! The constant cold water flow design ensures that in the event of a hot water supply
failure the Rada 32E will allow cold water to flow to the fixture.
In addition, Rada 32E is designed to shutdown the hot water supply in the event of a cold
water supply failure.
These features will only function if:
1.
There is a minimum of 20°C differential between the Hot Supply and the Blend set point
25°C.
2.
The Rada 32E has been factory set to deliver a maximum temperature at 25°C. It is
critical to note that under certain inlet temperature supply conditions, the constant cold
water supply feature may give the false impression that a blend set point has been
correctly established. However, the blend temperature may just be a function of the
combination of inlet hot water temperature and the constant cold water flow.
Important! The valve may actually be inadvertently set to deliver temperatures well in excess
of the set point but it is unable to do so due to the constant cold water flow. In this situation
the cold water failure safety shutdown has been compromised.
Rada 32E Installation
The Rada 32E Thermostatic Mixing Valve must be installed as per the Installation Schematic
1.
The Rada 32E should be installed in a horizontal position.
2.
The Rada 32E must be installed in a standard HOT-LEFT/COLD-RIGHT inlet supply
configuration. There are red(hot) and blue(cold) markings on each valve.
3.
Be sure to thoroughly flush the pipework before fitting the Rada 32E.
4.
Do not expose the Rada 32E or any of its fittings to extreme temperatures.
5.
The Rada 32E is serviced from the front of the valve as you face it. A minimum
180 mm clearance in front of the Temperature Control Handle is suggested for internal
parts access.
6.
The Rada 32E is pre-set at the factory to a 25°C Blend outlet temperature. The RADA
32E MUST NOT BE TEMPERATURE ADJUSTED ON-SITE.
7.
The Rada 32E is designed to control a single drench shower or combination drench
shower/eye wash station.
8.
The Rada 32E is designed to control a single eye wash station.
Multiple eye wash stations can be controlled by a single Rada 32E as long as the potential
multiple simultaneous demand does not exceed valve capacity.
9.
Ensure that the inlet supply pressures are nominally equal.
