The T301 is precision-engineered and should give continued superior and safe performance,
provided that:
1. The T301 is installed, commissioned, operated and maintained in accordance with the
recommendations given in this manual.
2. Periodic attention is given, as necessary, to maintain the product in good functional order
Product Specifications
1. The installation, commissioning and maintenance of this product must be carried out
in accordance with instructions given in this manual, and must be conducted by
designated, qualified and competent personnel.
2. Installation must comply with all local/National Water Supply Authority
Regulations/Bye-laws, and Building and Plumbing Regulations.
3. Warning: continued use of this product in conditions outside the limits listed in
this section can severely affect the performance and reduce the effective service
life and can present potential risk to users.

differential between blended
water and hot or cold water supply
NOTE: Mixers operating outside these conditions cannot be guaranteed by the scheme to
operate as TMV3 taps or valves.
The maximum differential between the Dynamic Flow Pressures for hot and cold supplies must be
1 - 5 Bar for High pressures and 0.2-1.0 Bar for Low pressures.
For optimum performance then the maximum differential Dynamic Flow Pressures between hot
and cold supplies must be 3 Bar for High pressures and 0.6 Bar for Low pressures. Ensure the
pressures are within the conditions of normal use.
We recommend that independant filters, pressure reducing valves, isolation and check valves
are fitted in an accessible location (not supplied).
The T301 MUST NOT be subjected to water temperatures above 80°C.
BS EN 806 Pt.2 Cl3.6 recommends that the temperature of stored water should never exceed
65°C. A stored water temperature of 60°C and a distributed water temperature above 55°C
is considered sufficient to meet all normal requirements and will minimise the effects of scale
in hard water areas. See 'Water Supply (Water Fittings) Regulations G18.2' and 'HSE Code of
Practice L8'.
