(D) OPERATION
1. The containers hold about 8.5 litres of water (2.2 U.S. Gallons). The flow rate of the unit is up to 3 L/hr with
a full top bucket but this rate will decline as it empties. You should allow about 3-4 hours for the top
bucket to fully empty into the bottom bucket.
(E) CARTRIDGE CLEANING
Note: Do not use soap or detergents when
cleaning. Use only water.
When the water is taking much longer to flow
from top to bottom, the cartridges require
cleaning. Use cleaning pad provided for best
results. Cartridge may be cleaned many times
until cartridge gauge 703-4 can be passed
over width of the ceramic. When 703-4 can be passed over the width of the ceramic it is time to replace the
cartridge.
The use of rubber gloves (i.e. dishwashing gloves) or other sensible hygiene
precautions is recommended during handling, cleaning or disposal of the
dirty cartridge.
1. To remove the cartridges for cleaning, disassemble by unscrewing the
wing nut and removing both wing nut and gasket. Take cartridge into
the palm of your hand and scrub the surface evenly under running
water using the cleaning pad supplied, until all discolouration is
removed and the original ceramic colour returns. Take care not to
contaminate the threaded nozzle area.
2. Replace cartridges into holes (gasket on the inside of bucket) and hand tighten wing nut under the lid.
Caution:
1. Only open the lower bucket when necessary as this could allow airborne bacteria to re-infect the water.
2. Do not store filtered water in uncovered containers.
3. Do not install a broken filter cartridge. Broken filter cartridges should be discarded and replaced with a
new cartridge. If a new cartridge is not immediately available, the hole in the top bucket should be
plugged with the hole-plug (859) included with the unit.
(F) CARTRIDGE LIFE
(Approximate): 6 months to 12 Months. Cartridge life is directly related to your water conditions, volume of water
filtered and frequency of cleaning. Frequent cleaning ensures best efficiency.
The SM4 can be kept in a cooler/refrigerator etc. while in operation.
