Cleaning Procedure
1. Mix four spoonfuls (40 g) of the cleaning agent with one gallon (approximate 4 liters) of clean
freshwater, in a clean pail. The water should be warm but not hot – maximum of 122° F
(50° C). Mix until the cleaner is completely dissolved.
2. Grasp the membrane housing with both hands and turn counterclockwise until it can be
removed. In its place, install the special membrane-cleaning housing provided with the kit.
Screw the housing all the way on by hand, but don’t overtighten. Place the suction strainer into
the pail of warm water.
3. Pump the handle. Discard the water coming from the discharge hose (on the end of the clean-
ing housing) for about 30 seconds, then place the return hose into the cleaning solution con-
tainer. Continue pumping the unit while recirculating, for about 15 minutes.
4. Stop pumping, and allow the membrane to soak for at least an hour. For severe fouling, an
extended soak period of 10 to 15 hours may be desirable.
5. After soaking, pump the handle again. Dump the first few pulses of solution that come immedi-
ately from the discharge hose. When the stream becomes cleaner, place the hose back into the
pail of cleaning solution and recirculate for another 30 to 60 minutes.
6. After cleaning, flush by pumping warm freshwater through the system (insert the alternate intake
hose into a pail of fresh water, and run the discharge water from the cleaning housing to a
drain). If fresh water is not available, you may use seawater if it is above 68° F (20° C).
7. Remove the cleaning housing and reinstall the normal membrane housing.
If the unit won’t be used for at least 7 days after cleaning, follow the inhibiting instructions under “Storage”.
Replacing the membrane element
If the membrane element is damaged, or can not be cleaned anymore, please replace the element
using the Katadyn Membrane Replacement Kit, article number 8012793, and follow the instruc-
tions below:
1. Grasp the membrane housing with both hands and turn counterclockwise until it can be
removed.
2. Remove the membrane element with a pulling-and twisting motion.
3. Clean the membrane housing with a warm mild detergent, rinse with clean water, wipe dry with
a lint-free cloth.
4. Lubricate the seals on the new element with a small amount of silicone lubricant.
5. Insert the element into the pump front, then push the reject tube assembly all the way into the element.
6. Slide the housing over the element. Screw it all the way into the pump collar by hand, but do
not overtighten.
Be sure there is no gap between the pump collar and the thread stop on the membrane housing.
