3.
Certain types of system can result in the
thermostatic mixing valve having excessive
‘dead-legs’ of pipework. Others allow an
auxiliary cold water supply to be added to
the mixed water from the mixing valve. Such
systems can disguise the onset of thermostatic
mixing valve malfunction.
4.
Ultimately, the user or attendant must exercise
due diligence to ensure that the delivery of
warm water is at a stable, safe temperature.
This is particularly important in such healthcare
procedures as supervised bathing of patients
unable to respond immediately to unsafe
temperatures.
5.
Care is required when making any adjustments
to flow or temperature. Make sure that the
temperature is suitable and has stabilised.
6.
To ensure continued safe operation of this
product, all
‘Critical Components
’ should be
changed every
5 years
.
7.
The designed service life of all critical
components used in this product is 5
years providing it is operated within the
recommended operating conditions and
parameters. However, when supply conditions
and/or usage patterns do not conform to the
recommended operating parameters and/
or conditions the critical components may
need to be replaced frequently in line with the
appropriate risk assessments.
8.
Continued use of this product in conditions
outside the specification limits given in this
manual can present potential risk to users.
9.
Important!
In healthcare applications such as
hospitals, aged person facilities, residential
care homes etc., and in any other applications
where the user is similarly at risk, irrespective
of supply and usage conditons or the evidence
of in-service tests, the Critical Components
MUST
be replaced at intervals of no more than
5 years.

SPECIFICATIONS
For applications which may be outside the
operating parameters which follow, refer to Kohler
Mira Ltd, or Local Agent.
For Type 3 installations, the supply conditions
specified in the
‘TMV3 Requirements Manual’
take precedence over the operating parameters
which follow.
Pressures
•
Max Static Pressure:
10 Bar
(1000 kPa)
•
Max Maintained Pressure:
5 Bar
(500 kPa)
•
Min Maintained Pressure (Gravity System):
0.15 Bar
(15 kPa) - 0.15 bar = 1.5 Metre head
from cold tank base to outlet.
•
For optimum performance supplies should be
nominally equal.
Temperatures
•
Factory Pre-set (Blend): 215 models:
41°C
,
222 models:
44°C
(bath fill applications, under
ideal installation conditions).
•
Optimum Thermostatic Control Range:
35°C
to 50°C
(achieved with supplies of 15°C cold,
65°C hot and nominally equal pressures).
•
Maximum Hot Water Temperature: 70°C*
*Note!
For optimum performance reasons 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.
•
Cold Water: up to
1°C- 25°C
(5°C-20°C for
Type 3 installations).
•
Minimum Recommended Differential between
Hot Supply and Outlet Temperature:
12°C
.
Thermostatic Shut-down
•
For safety and comfort the thermostat will
shut off the mixing valve
within 2 Seconds
if
either supply fails (achieved only if the blend
temperature has a minimum differential of
12°C from either supply temperature).
