HOW IT WORKS

Option 1. Use as a drinking straw.

Attach the open soft tube with the clamp attached, to the entry end of the filter and the short clear tube to the exit end, indicated by the arrows.
Suck the water up through the filter and in the direction of the arrows, directly into the mouth.

Option 2. Use with a folding water bottle or empty pop bottle

Fill the blue folding bottle or a pop bottle with dirty water and attach the filter using the screw thread.

The filtered water may be squirted directly into the mouth or into a clean container. Set aside part of the filtered water and use this with the syringe for the backwash filter cleaning process. 

Option 3. For use with buckets, drums, tanks.

Use with a single bucket in an emergency.
Using the 13/16” spade drill bit provided and a hand drill or electric drill, make a clean hole 1½” from the bottom of the bucket. Be careful to do this slowly, as harder plastic buckets may form burrs on the inside surface, which can affect the seal. If this happens a good silicone or plumber’s grease on the O ring with help it to seal.
When fitting the elbow hose barbs to the bucket, the O ring is to be on the inside of the bucket under the hex nut, which is then tightened. 

B. Using 2 buckets for a water system.

Using the 13/16” drill bit, drill a hole close to the top of the outside of the 2nd bucket and another hole 1 ½” from the inside base.
To install the spigot fitting, push the threaded end of the spigot through the hole with a seal on each side of the bucket wall, then screw the hex nut firmly onto the spigot shaft.
When fitting the two elbow hose barbs to the upper and lower buckets, the O ring is to be fitted on the inside of the bucket under the hex nut, which is then tightened.
The elbow hose barbs are oriented either vertically or horizontally to avoid the tube kinking and cutting off the water flow. Using 2 buckets as shown, the flow rate will be 100 - 120 gallons of clean water per day.
To improve the flow rate to over 400 gallons per day, make a 4ft. separation between the upper and lower containers as shown on the left. A larger separation between containers will increase the flow rate even more.
The filter will withstand a pressure of 50 psi (0.33 MPa) and may be attached to a piped water supply, up to that pressure. However, the fittings as supplied are for low pressure use and higher pressure fittings may need to be used with piped in water.

Back Washing the Filter

To back-wash the filter, close the clamp and disconnect the soft tube from the filter. Fill the syringe with clean water, then push the tip of the syringe firmly into the exit end of the filter, indicated by the arrow head and squirt the water back through the filter, opposite to the usual flow direction, allowing it to discharge onto the ground. 

Repeat this backwash process 6 - 8 times or until the discharge water is clear. Re-attach the soft tube and the filter is ready for continued use. Back-wash when the flow rate through the filter slows down, though daily back-washing is recommended, or when the filter is no longer needed and is being stored.
