Oasis MW8EBF Installation Guide

The Oasis MW8EBF is an in-wall refrigerated bottle filler with a contactless sensor, delivering 8.0 GPH of chilled water.

Before You Begin

• Plumbing: Provide a 3/8" O.D. water supply and a 1-1/2" or 1-1/4" IPS waste stub-out. Maximum supply pressure is 100 PSI. The stop valve, short radius P-trap, and waste pipe connector are not included.
• Electrical: A 115V grounded duplex receptacle on a 20A minimum GFCI device is required. A 2x4 junction box is provided, and flexible conduit is recommended.
• Wall opening: Prepare the opening and rough-in per the manual's roughing-in drawing, and allow extra depth for the water and waste lines.
• Codes and reference: Some states require a licensed plumber. See the user guide for rough-in dimensions and electronics setup.

Step-by-Step Installation Guide

1. Install the frame: Insert the frame into the wall opening and secure it to the studs. The front flange must sit flush with the finished wall. Set the drip tray in the frame without fastening it, and install the snap bushings.
2. Mount the chiller: Attach the cradle mounting angles to the frame flange without tightening, slide the cradle between them, then fasten it with the supplied screws and tighten all. Place the chiller in the cradle.
3. Connect the water: Run the supplied ball valve and 3/8" copper tube to the building supply. Fit 1/4" unions on the chiller inlet and outlet. Connect the solenoid valve outlet to the chiller inlet, and the chiller outlet to the bottle filler delivery fitting.
4. Connect the drain: Install a short radius P-trap between the frame's waste tailpiece and the waste stub-out.
5. Wire and mount the upper panel: Route the push button wire and tubing through the frame opening. As you set the panel in place, feed the long green ground wire and power cord terminals through the bushings. Attach the green wire to the junction box ground, plug in the cord, and fasten the panel with the supplied screws. The unit won't work without the ground wire.
6. Test and finish: Turn on the water and check all connections for leaks. Fasten the lower panel with the supplied locks or screws, then secure the drip tray grille with its 3 flathead screws.
