SS Gravity
Drinking Water Filter
Assembly, Operating and Maintenance Instruction
The SS Drinking Water Filter:
• is designed to be free standing on a stable surface
• can be fitted with 2, 3 or 4 ceramic filter elements
Note: the number of elements supplied will depend on the type of filter purchased
• should only be used for the treatment of cold water
• is designed to filter out harmful bacteria from water
Extreme cleanliness is important. Wear rubber gloves or wash hands
thoroughly before and after handling the product and take care to
ensure that no contamination of the components occurs during
assembly and cleaning.
Tap Assembly:
Remove the plastic nut. Moisten both rubber washers with clean water
Place one washer over the threaded part of the tap and then insert the threaded part
through the hole in the side of the bottom chamber as illustrated
Replace the second rubber washer onto the thread protruding through to the inside of
the bottom chamber and secure the tap in place with the nut. To achieve a tighter seal,
hold the outlet tap until the nut is hand tight. Then hold the nut and tighten the assembly
by rotating the tap body through at least a quarter turn to reach the upright position
Ceramic Filter Assembly:
Fit the knob onto the lid by inserting the screw up through the hole in the lid and
screwing on the knob, hand tighten only
Remove all protective packaging from the filter elements
Place a sealing washer over each filter element mount stem
Place the filter element mount stem through the holes in the base of the top chamber
Secure each filter element in place by screwing a wing nut onto the threaded stem
protruding through the holes
Put the top chamber onto the bottom chamber and place the lid in position
Filter Operation:
Ensure the outlet tap is in the “off” position
Fill the top chamber with water and replace the lid
Leave to allow the water to filter through the ceramic filter elements and collect in
the bottom chamber, from where it can be accessed via the tap. The maximum flow
rate will be achieved once the ceramic filter elements have become fully saturated -
usually after filtering of 2-3 full chambers of water
It is recommended that this first supply of filtered water is thrown away, as it may
contain loose material washed from the filter elements
The filter is now ready for use
The top chamber can be replenished with more water as required
Ceramic Filter Cleaning:
Due to filtration of particulate contaminants from the water during use, the flow of
the water from the filter may reduce over a period of time, depending on the quality
of the water. To restore the water flow to its normal level, simply clean the filter
elements as follows:
Remove the elements from the top chamber by unscrewing the wing nuts
Hold the filter elements in a bowl of water or under running water. To avoid
contamination of the open ended plastic threaded mount, take care to ensure that the
mount is always clear of the water NEVER use soap or detergents
Take a soft bristle brush or lightly abrasive pad and cup it around the circumference
of the filter element
Apply a gentle pressure with the brush or pad and slowly work down the length of each
filter element once, ensuring the cleaning is even over the whole filter element surface
Replace the filter elements as per assembly instructions above
Refill the top chamber and replace the lid
The filter is now ready for use
