Replacement of the cartridge
Follow standards in force regarding waste disposal of used cartridges.

damage. Tighten the housing bowl to housing’s head using a proper wrench. Do not over-tighten.
9. Turn-on the water mains, paying attention to completely remove the air left inside the housing using the
vent valves.
10. Slowly turn-on a water supply (tap) downstream of the
BIG F PRO

Warning
at re-start after every maintenance operation and/or refill change, when the filter’s bowl is unscrewed from
head, change the o-ring with a new one and carefully lubricate before tightening the bowl to the head.
Make sure that there are no water leaks from the product and especially control the tightening between the
housing head and the housing bowl. Continue checking that the tightening is good and there is no water
leakage for 48 hours following the installation and start-up. In case of leakage, open the housing, remove
the o-ring from the bowl, place a new o-ring and apply lubricant, then re-tighten the bowl to head and repeat
the leakage check as above.
Ask your vendor for original o-rings, lubricant and other spare parts.
Use the following step for a full disinfection of the Home and Facility lines before a new installation,
after service or shut down of the unit.
- Plug In the Unit and remove any “dead ends” in the lines to avoid bacteria harbour.
- Unscrew the sumps and remove the cartridges. Fill the first sump with 1 cup of Bleach ( 5.25%
Chlorine) and replace the sump.
- Slowly turn on the water supply and run the water for each faucet, toilet, shower heads etc, until
bleach can be smelled and close it. Wait 30 minutes to let the Chlorine disinfects the utilities.
- Turn off the water inlet and replace the cartridges in the unit. Turn on again and flush every faucet,
shower heads etc until chlorine smell can no longer been detected.
