Minimum hot inlet to mixed outlet temperature differential =10°C Note: Valves operating outside
these conditions can not be guaranteed by the Scheme to operate as Type 3 valves.
The highest flow rates will be achieved under balanced pressure conditions, but the pressure at the
valve inlets must be within a ratio of 5:1 under flow conditions and the size and layout of pipework
and fittings must take this into account.

Flush supply lines thoroughly before connecting Dolphin Alavo unit. Do not allow dirt, teflon tape or grease to
enter TMV.
C O N N E C T I O N
Before connection, the system operating conditions of inlet pressures, hot water temperature and hot
and cold water flow rates should be determined and confirmed to be within the expected conditions
of normal use.
Valves must operate in either a high pressure setting or a low pressure setting valves are not capable
of operation with, for instance hot water supply in one pressure range and cold water supply in the
other pressure range. In these conditions it is necessary to either boost one pressure or reduce the
other so that both supplies are within a common pressure range.
Correct location of the mixing valve is important
to ensure that it is accessible for commissioning
and servicing.
