6. Push & Tap 5 – 10 times until the back-wash device is in down position: the outlet is now acting now as the

Back-Wash unit. The flow is now reversed, and the filtered water combined with compressed air will flush

the dirt from the membranes.

Open the tap with the arrow again in open position and lift the outlet / Back-Wash unit slowly in 'up'

position and close the tap with the arrow. Push & Tap a few times on the outlet / Back-Wash unit till the unit is in 'down'

position. Repeat this action 5 times to ensure the filter module is flushed and cleaned by Back-Wash.

8. After Back-Wash cleaning, push the outlet / Back-Wash unit in 'down' position and turn in clockwise direction to lock

unit back in normal position.

9. Repeat step 1 – 8 if the filter is still clogged/blocked. Fil the Jerrycan once again with (visible clean) tap water and start

with normal filter action. Wait until the filtered water comes out of the output unit and release the pressure for an extra

Back-Wash action (repeat step 1 – 8). If the system is still blocked, this means the maintenance & service instructions are

not carefully followed: minimum every 6 months a

disinfection solution: prepare 10 liters of clean water to make a 0.5% (500 ppm) disinfection or sterilizing

solution with hydrogen peroxide (H2O2) and filtered water in case of bio-film. Practical: Add 200 ml of 5% to 2

liters of water and put the disinfection solution into the LFJC Jerrycan, shake well and perform a Back-Wash.

b. anti-scaling solution (citric acid: common household biological vinegar) in case of chemical blockage or scaling:

prepare 2 liters of water solution using a 200 ml kitchen biological household vinegar (max. 5% concentration)

or any other citric acid that is used for household applications. Practical: Add 2 liters of water and put 200 ml

of vinegar into the LFJC, shake well and perform a special Back-Wash.

'disinfection and cleaning', always rinse the water filter system with tap water before performing step b 'anti-

scaling'.

In extreme situations and / or in case of no results with Back-Wash & special Back-Wash, the module might need to be replaced.

c. FILTER MODULE STORAGE, STERILIZATION AND DISINFECTION

The membrane in the filter module of the LFJC will need to be disinfected before and after storage for a long time,

or when the LFJC is used intensively, or when the LFJC shows reduced flow ... this procedure is called

Wash'. To perform this

special Back-Wash,

follow carefully the instructions below:

Unscrew and remove the pump of the LFJC container – Jerry can and empty & rinse out any debris with clean water.

2. Fill up half of the LFJC

fluid to make a disinfection solution of 0.5 % to sterilize the complete system of the Jerry can.

3. Screw the pump back in the vessel and start pumping with the outlet unit arrow in open position and agitate the

disinfection fluid by shaking the Jerry can several times from side to side and up & down to make a proper sterilizing

fluid.

4. Start pumping with open tap outlet till approx. 1 liter of water flows out of the tap and close the tap outlet while

maintaining the sterilizing fluid in the complete system for 60 minutes.

5. After 60 minutes, perform a normal Back-Wash.

cycles

Unscrew the pump and remove it from the LFJC container and discard all remaining sterilizing fluid.

7. Perform a complete Back-Wash cycle as described before and discard the fluid to dry store the LFJC system. The LFJC is

now ready to be stored.

8. When the LFJC is to be used again, first fill up the Jerry can with clean water and flush the system by pumping approx. 1

liter through the outlet unit. The Jerry can is now ready to be used again.

d. MAINTENANCE OF LFJC PUMP

Unlock & unscrew and remove the pump from the LFJC.

Lift up the round section (screw of the pump) by carefully sliding the screw of the grey plastic part.

Note that the sealant rubber under the screw can obstruct the sliding on the pump rod.

Rotate the grey plastic section in open direction to release the rod of the pump

Pull out the rod of the pump out of the pump tube by lifting the handle.

Inspect the rubber piston and apply a small amount of silicone-based grease around the rubber piston cup.

Replace the rubber piston O-rings if needed (by damage or worn down) and re-assemble the pump

8. Re-assemble the pump tube and pump handle: ensure that the grey plastic section locks into the pump screw of the

pump tube and screw the pump back into the LFJC.

repeat the process described in FILTER MODULE BACK-WASHING and
