Installation Requirements
This thermostatic mixer valve must be installed
in compliance with current Water Regulations. If
you have any doubts about the Water Regulation
requirements contact your local water services
provider or use the services of a professional
plumber.
This mixer valve is suitable for use with the following
water supply systems:
Gravity Fed Hot and Cold (pressure balanced) 0.1 - 1.0 bar
Gas Combination Boiler (multi-point) 1.0 - 10 bar*
Unvented System (pressure balanced) 1.0 - 10 bar
Pumped System 1.0 - 10 bar
IMPORTANT: If you install this mixer with a
gravity fed system, there must be a minimum head
(vertical distance) from the underside of tile cold
water storage tank to the showerhead position of
at least 1 metre.
Before connecting the mixer, water should be flushed
through the system to remove all debris that might
otherwise damage the valve.
* If pressure is in excess of 3.5 bar, a pressure-
reducing valve should be fitted.

4. Install the escutcheons to the valve body.
3. Remove the guide pins from the reverse sides of the screw
covers. Place each into one of the three screw holes on each
adapter flange.
Installation
The hot supply MUST be on the left side, and the cold
supply MUST be on the right. If the unit is cross-piped,
it cannot function properly.
The hot and cold piping must be securely fastened in
the wall. Flush the hot and cold lines thoroughly before
installing the valve body. Damage to the cartridge
caused by debris is not covered under the Hansgrohe
Warranty.
1. Wrap PTFE tape round the S-unions and screw into the
backplate elbows.
2. Use a 12 mm allen key (not included) to install the offset
adapters into the wall. Use the spacer gauge to check for
proper spread, and a torpedo level to check for level. Make
adjustments to each side using the 12 mm allen key until
proper spacing and level are achieved.
