Filter Replacement Methods

• Replacing the quick change filters
First close the inlet water ball valve. Pull out the water pipes on the both
ends of the old filter cartridge. (see diagram 10, 11 for the usage
method of quick fittings). Throw away the old filter cartridges. Then
make the connection of the new inline filters on the both ends.
Finally put the filter cartridge into the big clip. Pay close attention to
the arrow on the filter cartridge and connect the filter cartridge with
the water pipes following the arrow direction, the left side is for outlet
water and the right side for inlet water.(see diagram 15).
IMPORTANT:
It is recommended that filter replacement is carried out by qualified
after-sales staff.
Always use gloves when replacing the filters. Replaced filters should be
disposed in a tightly closed garbage bag.
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.
Outlet water
• Storage tank capacity
The storage tank on your equipment has a stated capacity of 2.5G.
However this figure is its theoretical capacity and its actual storage
capacity is about 70%-80% of the stated value, which is app. 2G
• 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.
