GENERAL FEATURES & TECHNICAL INFORMATION
General Features:
In the event of a sudden loss of the cold water supply, the hot water supply will be cut-off (response time
is 1 - 2 seconds) if the mixed water temperature selected is less than 42°C and the temperature differential
between the hot water and the mixed water is more than 15°C. Filters and non-return valves at the mixer
inlets protect the thermostat and prevent any back-flow into the pipework system.
Note: If, instead of cold water, the hot water returns through the mechanical mixer, there is no anti-scald
fail safe. We recommend installing a non-return valve on the cold water inlet of the mechanical mixer.
Technical Information:
• The factory pre-set is 38°C, with a temperature differential of 50°C between the cold and hot water.
• Range of mixed water settings: from 25°C to 40°C for H9739 and H9739S, and from 25°C to 41°C
for H9741, H9741S, H9741TP and H9752S. The maximum temperature limiter is set at 38°C
for H9739, H9739S and H9741TP. Models H9741, H9741S, and H9752S can be set at 41°C
by pressing on the button on the control knob , (Fig. C).
• Maximum hot water temperature: 85°C.
• Min./max. pressure: 1 - 5 bar (recommended 3 bar). Difference in pressure at water entry point:
maximum 1 bar.
• Safety: hot water shut-off in the case of loss of cold water. The hot water fail-safe is active
if the difference in temperature between the hot water and the cold water is more than 15°C.
• Flow rate regulated at 9 lpm.
• Temperature adjustment control is on the left and the flow-rate control is on the right.
INSTALLATION (Fig. A and B)
2 off-set connectors enable adjustable pipe-centres (150mm +/-20).
Mixers supplied with standard connectors:
1. Using PTFE or a waterproof sealant on the ½" threaded connector , tighten offset connectors
at right angles to the wall. Ensure a waterproof seal between the supply pipes and the finished wall.
2. Mount the offset connectors  ensuring that the mixer is horizontal. Tighten the cover plates 
onto the offset connectors  by hand.
