High pressure system – Instantaneous hot water systems, e.g.
combination boilers (Fig.1)
The high pressure Digital Mixer Processor unit MUST be installed with a multipoint gas
water heater or combination boiler of a fully modulating design (i.e. where the water draw-
off rate indirectly controls the gas flow rate to the burner).
A drop tight pressure reducing valve MUST be fitted if the supply pressures exceed 500kPa
(5 bar) running.
An expansion vessel MUST be fitted, (and regularly maintained) if any form of backflow
prevention device is fitted ie. PRV. This will ensure that excess expansion or pressure pulses
Important if using wireless connected devices
Metal objects such as steel baths, cold water storage tanks, hot water cylinders, radiators,
foil lined plaster board and even thick brick walls can all dramatically reduce the wireless
operational range.
Interference from other wirelessly controlled devices and radio signals can dramatically
reduce the ability of the wireless Digital Mixer Shower to maintain a good, consistent
wireless signal. This may include mobile phones, cordless phones, radio controlled toys,
wireless doorbells etc.
If you encounter difficulty whilst setting up the wireless connectivity of the Digital Mixer
Shower, ensure all other radio interference is temporary switched off.
Failure to follow these wireless connectivity guidlines can result in poor, intermittent or
failure of the communication between the Digital Control panel and Digital Mixer Processor
unit.

do not damage the product. This may already
be installed within the boiler (check with
manufacturer) and is in addition to the normally
larger central heating expansion vessel.
The layout and sizing of pipework MUST
be such that nominally equal inlet supply
pressures are achieved and the effects of other
draw-offs are minimised.
Combination boilers are not always able to
supply an adequate ow rate of hot water,
particularly in winter, Triton recommends
tting a ow regulator (supplied with
the Shower) into the Hot inlet of the High
Pressure Digital Processor Unit prior to
installation. Refer to the table for details
(see Fig.2).
