Step 5: Complete plumbing connections on SGLP-RO System
NOTE: Refer to installation diagram above.
1) Install installation parts onto the SGLP-RO unit and close the inlet and sample water
valves.
2) Connect inlet water supply to the SGLP-RO system inlet using either the quick connect
fitting or the supplied hose barb (if using hose).
3) Install drain line from permeate pump brine out port to a drain.
4) Run tubing from the SGLP-RO outlet to the Duke oven.
NOTE: The SGLP-RO comes with two outlet fittings to accommodate different types
of tubing. One fitting is a ¼” barb as shown in the diagram above. This fitting should be
used with flexible tubing. A 3/8” stem x ¼” quick connect fitting is also included for rigid
