Water Quality
Use only ASTM Type II, or better, deionised water, which must have a conductivity of less
than or equal to 1
μ
S/cm (greater than 1 M
Ω
resistivity) @ 20°C and should be replaced
as required. Water quality should be checked prior to being used to supply the Precision
Hydrogen Generator.
Use of water in the Precision Hydrogen Generator with a purity not specified above will
result in a reduced efficiency of hydrogen production, failure of the generator and loss of
warranty.
Water should be stored in a UV protected dark container away from direct sunlight. The
bottle should have a vented lid to minimise any dust or debris contaminating the water
supply. A suitable external water bottle is available from Peak Scientific.
Note: Customers should check the water quality of the external water supply once a
week to maintain the health of the generator.
Automatic Filling
The Precision Hydrogen generator uses an automatic water filling system, whereby
sensors in the unit’s internal water tanks detect when the water level reaches a
minimum.
This then refills the tank using a rear connection to an external DI water supply. The unit
should be connected to the water supply as shown on the next page.
Using the length of Tygon tubing and the hose barb fitting from the fittings kit, attach
the barb to the tubing. Then connect one end to the water supply and the other to the
Fill port at the rear of the Precision Hydrogen.
For efficient water filling the external supply should be no more than 2 metres away
from the connection on the generator.
The DI Water Supply source MUST NOT be located higher than
the height of the surface that the Precision Hydrogen generator is
placed upon. A supply located higher than specified will result in the
generators internal water bottle over filling.
A pressurized DI Water Supply Source will also result in the internal
water bottle over filling, and therefore MUST NOT be used.
