The unit should come with two connectors for each end of the unit.

1. Pull out the caps which blank the threaded holes at each end of the pod, wrap a few layers of PTFE plumbers tape around the threads of the connectors and screw them into the pod for a water tight seal.
2. Clip the included mounting brackets onto the pod and then onto the RO membrane housing.
3. Take your product water line (good RO water pipe) and cut it cleanly so there is enough pipe to push into the Di pod connector from the RO unit.
4. Push the left over pipe into the connector on the other end of the Di pod to go to your collection vessel.

Water can pass through the Di pod in either direction, it is most commonly installed with the water going in to the cap end but this will make no difference to its operation.

When replacing the RO membrane is is important to disconnect the Di pod. If this is not done the Di resin will be exausted very quickly as the new membrane flushes.
