Operating Conditions of Use
Prior to installation the operating conditions of use must be checked. The table
shown (Table 1) contains details of the necessary conditions of operation.
NOTE: If your water system cannot meet these conditions then the valve cannot
be guaranteed to operate as a Type 2 valve. This valve is suitable for use
with Low Pressure (BSEN1287) operating conditions.
Please note valves must always be operated within the range for BS EN1287.
Operating pressures above 5 bar will require installation of a pressure reducing
valve (not supplied)
TABLE 1
(Valve designation of use for this product: LP Tub BS EN1287)
BS EN1287
MAXIMUM STATIC PRESSURE
10 BAR
FLOW PRESSURE
0.1 – 1 BAR
(Note; Minimum 0.2 bar required for this product to meet LP Tub application)
HOT SUPPLY (°C)
55-65
COLD SUPPLY (°C)
MAX 25
MAX MIXED TEMP (°C)
MAX 46
Note:
46°C is the maximum mixed water temperature from th e bath tap. The
maximum temperature takes account of the allowable temperature
tolerances inherent in thermostatic mixing valves and temperature losses
in metal baths.
It is not a safe bathing temperature for adults or children.
The British Burns Association recommends 37 to 37.5°C as a comfortable
bathing temperature for children. In premises covered by the Care
Standards Act 2000, the maximum mixed water outlet temperature is 43°C
Temperature Adjustment
This should be carried out by a competent person and only when absolutely
necessary.
Turn the handle anti-clockwise to fully hot.
Turn on the tap handles to allow water flow from the spout, let this run for
1 minute.
Check the temperature using a thermometer, this should read 46 °c, if not leave
the temperature handle in the fully hot position and remove the central
temperature control cap, by using a thin blade screwdriver, push this through
the hole to the rear of the central handle and force off the cap, remove the
centre screw in the handle, you do not need to remove the handle,.
This will expose the cartridge adjustment grub screw, insert an allen key into the
hole of the handle and locate into the grub screw and turn anti-clockwise to
increase the temperature or clockwise to decrease.
Ensure that you do not exceed the 46 °c.
Then re-fit the components to the mixer.
