Low-Pressure Gravity Fed
Systems Installation
IMPORTANT: The minimum head for the
operation of the Triton Xerophyte Mixer
Unit is 100 mm. For optimal operation, the
Xerophyte Mixer Unit MUST be put as
close as possible to the hot water cylinder.
Shortening the distance between the
Triton Xerophyte Mixer Unit and the hot
water supply will shorten the warm-up
period.The Triton Xerophyte Mixer Unit
MUST be fed from a cold water cistern and
hot water cylinder providing nominally
equal pressures.
For the operation of the shower only,
it is recommended that the cold water
storage cistern is capable of holding at
least 114 litres (25 gallons). Where other
hot and cold outlets are likely to be in use
simultaneously, the storage capacity
should be increased to 228 litres
(50 gallons).
IMPORTANT: Pipework layouts and connections MUST be such that other draw-offs will not
affect water supplies to the Triton Xerophyte Mixer Unit, shared supplies may lead to air
locking or water starvation. It is, therefore, essential to have independent hot and cold
supplies to the Triton Xerophyte Mixer Unit.
If the hot water draw-off is incorrectly positioned, air may be drawn into the hot supply from
the vent pipe causing spluttering, and temperature fluctuations at the showerhead.
Any draw-off for the Triton Xerophyte Mixer Unit MUST point DOWN (to avoid air-lock
problems) and MUST be BELOW the vent pipe tee.
Failure to correctly position the draw-off will result in poor performance or other problems
with the Triton Xerophyte Mixer Unit.
Note: If the hot water source is moved or replaced at a later stage, a factory reset is required.
