Commissioning must be carried out in
accordance with these instructions, and
must be conducted by designated,
qualified and competent personnel.
Exercising the Thermostat; Thermostatic
mixing valves with wax thermostats are
inclined to lose their responsiveness if not
used. Valves which have been in storage,
installed but not commissioned, or simply
not used for some time should be
exercised before setting the maximum
temperature or carrying out any tests. A
simple way to provide this exercise is:
•
Make sure that the hot and cold
water are available at the valve inlets,
and the outlet is open.
• Move the temperature control rapidly
from cold to hot and back to cold
several times, pausing at each
extreme.
Bath Fill Maximum Temperature:
Note! For Type 3 Healthcare installations
the maximum blend temperature is
determined by the application, refer to the
TMV3 Requirements Manual.
The maximum blend temperature
obtainable by the user should be limited, to
prevent accidental selection of a
temperature that is too hot. All Rada
thermostatic mixing valves are fully
performance tested and the maximum
temperature is preset to approximately 41°c
(222 models -44°c) under ideal installation
conditions at the factory. Site conditions
and personal preference may dictate that
the maximum temperature has to be reset
following installation. This mixing valve is
provided with two methods of temperature
setting, an adjustable temperature control
knob which allows the user to select the
blend temperature between ambient cold up
to a preset maximum, or if considered more
appropriate, a locked cap can be fitted,
allowing no user adjustment.
Maximum Temperature Setting:
Check that an adequate supply of hot water
is available at the hot inlet of the mixing
valve. The minimum temperature of the hot
water must be at least 12°c above the
desired blend, however during resetting
this should be close to the typical storage
maximum to offset the possibility of any
blend shift due to fluctuating supply
temperatures. Check that both inlet
isolating valves are fully open and the inlet
filters are clean. Temperatures should
always be recorded using a thermometer
with proven accuracy.
Commissioning bath fill
1. Remove the temperature knob and
indicator trim or locking cap using a
3mm hexagonal key.
2. Pull of the temperature hub.
3. Using the temperature hub, rotate the
spindle until the required maximum
blend temperature is obtained at the
discharge point (rotate clockwise to
decrease temperature). If resistance
is felt, do not use force to turn any
further, as this can damage internal
parts.
4. Once the desired maximum blend
temperature has been achieved, refit
the hub without disturbing the spindle.
For adjustable temperature: Position
the hub such that the lug is against the
side of the stop of the cartridge face,
thus preventing anticlockwise rotation
past the maximum temperature stop.
For locked temperature: Position the
hub such that the lug is between the
stops on cartridge face, thus
preventing any rotation.
