PRE-INSTALLATION NOTES
The thermostatic mixing valve must be installed in such a position that maintenance of the
TMV, its valves and the commissioning and testing of the TMV can be undertaken.
Ceratherm T125 is an exposed two hole thermostatically controlled shower mixer. This

Mounting. Product are supplied with a pair of wall mount escutcheons. Mixer is intended to be installed
on a wall or panel arrangement.
Flow regulation. There are no flow regulators fitted inside these products.
Mesh filters (strainers) integral to the inlet seals are intended to protect the check valves from water
borne debris. These are fitted inside the inlets of the product, see section 20.
Thermostatic cartridge. Additional mesh filters (strainers) are fitted to the thermostatic cartridge to
protect it from water borne debris, see section 17.
Product dimensions. Check the dimensions shown in section 1, ensuring the mixer will fit on the
intended bath. Plan position of proposed shower kit.
Product box contents. Ensure you have all the parts shown in section 2.
Bath holes for rim (deck) mount products. The two holes in the bath should be in a suitable location,
drilled Ø30 (Ø35 max) at 180 centres. Allow sufficient space around the mixer to permit easy operation
of the handles & facilitate easy cleaning
Service Valves. A pair of service valves (for isolating both water supplies) MUST be fitted to permit
future maintenance of this product. These should be fitted as close as practicable to the water supply
inlets of the mixer & in an easily accessible location. NOTE: service valves are not supplied with thiese
products, see section 23.
Shower Kit. The flexible shower hose from the shower kit can be screwed onto the G1/2" shower out-
let nipple located on the underside of the mixer body. Ensure adequate steps are taken to secure the
shower hand set and the arrangements comply with water regulations.
Shower hose retainer. Both products are supplied with a bracket to restrain the flexible shower hose
& prevent the hand shower head from falling into appliances such as the bath tub or shower tray. The
hose can be restrained by a bracket on the shower riser rail or separate wall bracket.
Mixer Controls. The mixers have dual control handles, the left handle allows temperature adjustment
of the water. For A7592AA, the right handle permits flow control of the mixed water. For A7594AA, the
right handle also divertes water between the overhead shower & the shower hand set. The bath fill &
shower mixer A7593AA also has diverter control within the right handle, allowing user to direct mixed
water between bath fill & shower outlet, see section 8.
Water Supply Pipes. Both hot & cold water supply pipes should be securely attached to a wall (or floor)
using suitable fixing clips. Supply pipes must Ø15 or Ø22 for the rim (deck) mount products. The wall
mount brackets accept only Ø15 pipes. Note: Hot water supply should be connected to the left inlet of
the mixer (viewed from the front).
