Pour the purifier down the hose before connecting to rv. . Then adjust your knobs to tank fill and turn on the hose water.
If you can verify your water uses a house filter PRIOR to entering fw tank you can also pour purifier in filter canister after removing cartridge.
If you use the hose to add the "purifier" remove the water filter element FIRST reinstall the housing and then proceed to fill the tank.
