against the fitting. With the collet held in this position the tube can be removed Once the outlet tubing is disconnected,
please remove inlet tubing at Point O. Remove old filter and discard.
3) The new PH filter will come with 2 End Plugs. Please remove the plugs before connecting the tubing to the filter.
4) To reconnect the tubing to Point O and Point P, push the tubing into the Quick Connect fitting, then
gently pull back on the tubing to make sure the connection was secured.
5) Please drain a full tank of water before use.
6) Check for leaks!
