During the first use, Carbon Cartridges will leave a carbon dust into the
water. To prevent carbon dust flowing into RO Membrane cartridge,
Carbon Filters should be flushed before the activation of the unit. If this
flushing will not be done, Carbon Dust will shorten RO membrane,
While changing the pre-filter, Second Stage Carbon Block and Fourth Stage
PAC filters should also be flushed.
Follow the spets on page 18 to flush the pre-filters.
General Information
• RO membrane water production volume
The water output volume of the RO membrane component is influenced
by inlet water pressure and water temperature. Your equipment’s
declared volume of 75GPD is tested under a net pressure of 0.5MPa
and inlet water temperature of 25C . If net pressure is less than 0.5MPa
or if the inlet water temperature is less than 25C, water output volume
of the RO membrane component will be less than 75GPD.
• Storage tank capacity
The storage tank on your equipment has a stated capacity of 3.2G.
However this figure is its theoretical capacity and its actual storage
capacity is about 70%-80% of the stated value, which is app. 2.0-2.5G
• Disposal of old filters
After replacing old filters, they cannot be cleaned and reused; it is
recommended that you dispose of them with solid waste garbage.
