(Built-in models)
. Carefully lever off the concealing plate (408 76) by inserting
a medium slotted screwdriver blade under each corner, see
MAINTENANCE Figure
2
.
4.
With removal clip still in place, unscrew the head nut using 35 mm A/F wrench;
this will release the body shroud and also begin to draw the Thermostatic cartridge
out of the body (see
MAINTENANCE Figure 3
.)
Warning!
some residual water may be released. Pull the Thermostatic cartridge
free of the valve body.
5.
Outlet Reversal:
rotate the valve body 1/2 turn so that the outlet is in the
opposite position. Do not rotate the Thermostatic cartridge.
Reversed Inlets:
rotate the Thermostatic cartridge 1/2 turn, which reverses the
position of the cartridge hot and cold inlets.
6.
Carefully push the Thermostatic cartridge back into the valve body, checking
that the 2 cartridge inlet port seals remain in place, and locate cartridge lugs into
body slots.
Note!
The red and blue markings on the cartridge will now not correspond with
the body markings, so to avoid future confusion remove the red and blue stickers
from the valve body.
7.
Carefully align and then tighten the head nut;
do not over-tighten
(max torque
2.5 N/m - 1.85 lbf ft).
8.
Complete
INSTALLATION
, if appropriate.
9.
If the mixing valve body has already been installed, restore hot and cold supplies
and check for any leaks.
10.
Align and refit the body shroud and temperature knob assembly/locking cap so
that the markings will be visible to the user (built-in models: first refit the concealing
plate).
11.
The maximum temperature may now need resetting; check, and if necessary
refer to
COMMISSIONING
.
Outlet Reversal
should be done
prior
to installation of the mixing valve body.
Reversed connections
can be altered before or after the mixing valve has been
installed.
The
procedure
for both operations is as follows:
1.
If the mixing valve body has already been installed, isolate the supplies to the
mixing valve, and open an outlet fitting to release pressure and to assist the
draining of residual water.
2.
Remove the temperature knob assembly (442 01) or locking cap (408 51/52),
using 3 mm wrench key provided (see
MAINTENANCE Figure 1
).
Do not
remove
the temperature hub.
reversing, it is easier to simply rotate the complete mixing valve by 1/2 turn, and then
reposition the temperature knob or cap.
