Product Description

The T301 is a lever operated sequential mixing valve for basins. It uses proven

thermostatic technology for temperature control. A single lever provides sequential

operation from OFF through COLD and WARM to a maximum blend temperature

preset at 41°C, which can be adjusted if required.

The T301 is designed for single or two hole basins. The supply connections are via

flexible inlet tails which incorporate non return check valves and filters.

The installation must be in accordance with Water Regulations and Bylaws.

The T301 is designed to deliver water consistently at a safe temperature.

In keeping with every other mechanism, the mixer tap cannot be considered as being

functionally infallible therefore the tap cannot totally replace the vigilance of nursing/

supervisory staff where that is necessary. Provided it is installed, commissioned,

operated and maintained within these recommendations, the risk of failure is not

eliminated but can be reduced to a minimum.

SITE REQUIREMENTS

Water pressure requirements - Running water pressure: Mains fed - 0.2 bar min. - 5.0

bar max. Maximum static water pressure: Gravity and mains - 10 bar. The T301 is

designed for higher pressure systems found in the UK up to a maximum of 5 bar running

(dynamic) pressure. For effective operation of the internal seals, the maximum static

pressure must not be exceeded.

Water minimum flow rate. For best performance within the specified running pressure

range a minimum flow of 8 litres per minute should be available to both inlets.

Water temperature requirements. Maximum hot water temperature: = 80°C

Recommended maximum: = 65°C Minimum hot water temperature: = 55°C

Maximum cold water temperature: = 20°C
