Regnum Jaco Inline GAC Coconut Filter

By reducing chlorine early in the system, it protects the reverse osmosis membrane and downstream filters. Jaco-type fittings and elbows are screwed into the threaded ports at both ends to connect it to the unit.

Features

Granular activated carbon reduces chlorine, taste and odour
Coconut shell-based activated carbon
Protects the reverse osmosis membrane from chlorine
Threaded (Jaco) connection for a secure, leak-tight fit
Sealed housing; no housing cleaning needed at replacement
Fits standard 2.5" Jaco inline filter positions

Applications

Residential reverse osmosis (RO) units
Under-sink and countertop water purifiers
Mains-fed (bottleless) water dispensers
Feed lines of refrigerators, ice and coffee machines
Office and small commercial treatment systems

Use: Disposable, sealed

Shut off the unit's water supply and open the faucet to relieve pressure.
Disconnect the tubing and unscrew the fittings and elbows from the used filter.
Wrap the fitting threads with PTFE tape and screw them into the new filter, observing the flow direction (IN → OUT).
Reconnect the tubing, slowly reopen the water supply and check the connections for leaks.
On first use, flush for at least 5 minutes until the water runs clear to remove carbon fines.

The filter is disposable and cannot be opened or washed. Replace it after 9,462 litres or every 6 months at the latest; replacing it together with the other pre-filters in the system is recommended. Do not overtighten the fittings. Do not use with microbiologically unsafe water or water of unknown quality without disinfection.
