Katadyn Expedition Filter

Compliments of
Black Mountain Stores, Inc.

1. Carefully remove Katadyn Filter from canvas carrying bag.
2. Loosen holding screw 120179 and then fix the Filter with its pump incorporated by means of this screw at the correct operating level on the support 120165.
3. Loosen wing screw 20672; turn locking device down on both sides; raise lid 120170 with the Filter element 1040 screwed in, and remove the protecting covering applied for transport. Make sure that the Filter element is properly screwed in; gasket 20674 (6) must seal tight. Be careful not to tighten the screw excessively, as this may make the rubber gasket squeeze away.
4. Immerse sucking hose 22315 and sieve 22306 into the raw water.
5. Turn outlet tube 120172 to front; this tube should be absolutely clean; fasten cap nut 120171.
6. Start pumping by moving the pump handle 22316 up and down. After about 20 pumping strokes the clean, disinfected water will flow through outlet tube 120172.
2. Cleaning

The Filter element must be cleaned when, after having been in operation for some time, a certain resistance to the filtration process is noticed, while the water flow diminishes, or the overpressure relief valve 22307 is discharging (at 112lbs p.s.i.). The higher the contents of suspended matter present in the water the more frequently the Filter Element requires cleaning.

1. Loosen wing screw 20672 and turn locking device down on both sides.
2. Take the ceramic element 1040 with lid and outlet tube out of the filter housing and clean with the brush 20521 (contained in the inner pocket of the canvas bag). Any coating deposit must be brushed off until the natural light colour of the ceramic is restored. Use no other abrasive or scouring agents. Do not treat with any cleaning agents or disinfectants. Do not boil the filter element, nor sterilise it with steam. Do not dry the filter element by placing it on hot surfaces, in ovens or with microwave units.
3. Clean the filter housing 20677 periodically.
4. Should the Filter not be used for some time, remove the Filter element and clean it as described under #2. Allow it to dry for at least 5-10 hours in a ventilated room. This will prevent the Filter element from musty smell.
5. Make sure that the Filter element is screwed in tightly (See under Operation #3). Reassemble the Filter.
6. To ensure proper functioning of the pressure relief valve 22307, regularly remove and clean this valve.
7. Protect clean water outlet of the Filter element and outlet tube against pollution.
