Rada 32E
A suitable range is 16-37°C. Generally, temperatures higher than 37°C may cause
chemical interactions with the skin and result in further damage. At 16°C and below
hypothermia becomes a concern. Consulting a safety/health advisor will be a helpful
aid in the determination of the best temperature parameters. No two hazards are
exactly the same and each should be evaluated on a case-by-case basis".
Point of Use
Rada 32E Thermostatic Mixing Valves are suitable for installation at or near a point
potential for simultaneous operation.

Rada 32E
Rada 32E is a Thermostatic Mixing Valve of “sealed for life” disposable cartridge construction.
For Emergency Drench Showers - The Rada 32E will pass a specied minimum of 76
litres per minute (l/min) and will ow a minimum of 38 l/min from direct cold water supply in
hot failure mode at 2.7 bar (40 psi) maintained equal inlet supply pressure.
For Emergency Eye Wash Stations - For single or multiple xture installation, the Rada 32E
will control accurately at ow rates from 76 to 8 l/min.
In ow applications between 76 and 38 l/min, the Rada 32E will pass approximately 50% of
original ow setting in hot failure mode.
In ow applications between 38 and 19 l/min, the Rada 32E will pass approximately 80% of
original ow setting in hot failure mode.
In ow applications below 19 l/min, the Rada 32E will pass approximately 95% of original
ow setting in hot failure mode.
Operational Specications
1. Site Adjustable—Mechanical maximum-temperature limit stop and single-temperature
locking features as a function of the temperature control handle design.
2. Thermal shutdown feature is designed to protect user from unsafe water temperatures
or hot water/chemical reaction should cold supply be interrupted during use.
3. Unique constant cold water ow design ensures that in the event of a hot supply failure
the Rada 32E will allow cold water to ow to xture.
4. Unique constant cold water ow feature allows the inlet hot water supply to be set within
a prescribed range, thus limiting the potential outlet temperature to a safe maximum in
the event of misadjustment, unauthorized tampering or thermostat failure. This feature
presumes that the correct initial commissioning was performed and that the cold water
supply has not been interrupted.
Technical Specications
• 32E - 1” BSP Female or 28 mm Compression
• 32E BSP - 3/4” BSP Male
• Chrome-plated DZR brass/polymer construction
• Operating pressures must be nominally equal
Maximum: 6.9 bar*
Minimum: 2.7 bar drench showers, 1.4 bar eye wash
• Integral replaceable cartridge-type inlet check valves
• Dual thermostatic elements
• Integral replaceable inlet strainers
• 38 LPM constant cold water ow in hot failure mode to open outlet at 2.7 bar pressure
drop
*High water pressures may deliver a volume and spray force that are injurious to the user.
Check with xture manufacturer or regulate water pressures within acceptable range.

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 ttings
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
maintenance, supervisory and 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.

Important! To ensure continued safe operation of this product, it should be checked and
maintained (see servicing and maintenance section). In addition All 'Critical Components'
must be changed every 5 years, irrespective of supply and usage conditions or the evidence
of in-service tests. However, when supply conditions or usage patterns do not conform to the
recommended operating parameters the cartridge may need to be replaced more frequently
in line with appropriate risk assessments.
Critical components are Cartridge Assembly pt. no. 1812.007 and inlet service pack 1847.232
or 1847.233 where applicable.
*Note! For optimum performance it is recommended that the maximum hot water temperature
is limited to 65°C.
Caution! During thermal disinfection the mixing valve can operate up to 85°C for short
periods ensure safety precautions are followed during discharge. Chemical disinfection agents
e.g. chlorine/chloramines combined with higher temperatures will affect the life of the product
adversely and could detrimentally affect the thermostatic performance, to ensure continued
safe operation refer to ‘Safety’ Critical components.
