Pool Waterfalls Installation Guide

DESIGN PREFACE
Waterfalls naturally narrow as they fall. Oasis presents the following waterfall height specifications for this waterfall unit:
1) Maximum waterfall height.
2) Width of sheet of water at the maximum waterfall height.
3) Length of waterfall fixture.
4) Recommended waterfall height from lip of the fixture to
the pool water surface.
5) Width of the sheet of water at the pool water surface

Installation tips:

STEP I.
Notching the Bond Beam
1. Mark the area prior to excavation with stakes and construction ribbon.
2. Prior to steel installation, mark the exact area for the waterfall.
3. Allow 1 inch on each side and 3.5” below the form for the Waterfall (Example: for a 12” waterfall, offset the steel pattern to allow for an additional 1"
space on each side of the waterfall. For a 12” waterfall: 1”+1”+12” = 14”).
4. Measure 3.5” down from the top of the frame.
5. Offset the steel rebar to allow for the cut in the bond beam.
6. Mark a channel for plumbing the waterfall. For single inlet waterfalls the channel is at the center of the notch. Longer waterfalls require more water and
thus more inlets. For a 6' to 8' waterfalls, position the waterfall over the bond beam and mark the locations of the inlets.
7. Make sure the cuts in the Bond Beam are positioned correctly before proceeding.

STEP II.
Installing the Waterfall Unit
Note: The top of the Oasis Fall is where the throat and lip are.
1. Glue and connect a length of 1.5” diameter schedule 40 PVC piping approximately 12” long (or to extend beyond the back of the bond beam) into the
back of the waterfall. This step will allow you to complete the mortar set and complete the plumbing later. (Refer to STEP III-Plumbing before proceeding)
2. Place the Oasis Fall in the pre-cut notch in the bond beam.
3. Level the top of the Oasis Water Fall to the upper edge of the bond beam with tile shims, fill the area below and in back of the unit with concrete brown
coat or similar material.
4. To insure that the waterfall stays in level position until the concrete is dry. Cover the finished setting with 1/2” or 3/4” plywood. Place bricks or a cinder
block on top of the plywood so the weight is evenly distributed over the waterfall and the bond beam. Check with a level.
Note: This procedure must be always be followed for all installations. Unleveled installation will produce an uneven water flow.
6. When the concrete is dry remove the plywood cover. Before plastering make sure the protective grout guard is in place. Cut the tile to fit under the lip
of the spillway and secure with thin set or a similar compound. Be sure the finished wall surface is flush with the waterfall lip edge.

Important! Do Not Remove the protective grout guard until the installation is complete

Trouble Shooting:

PROBLEM	CAUSE	SOLUTION
The flow is not smooth or there is a gap in the flow	Debris in the opening	Use a thin object to remove the Gap in the flow debris by sliding the object along the opening.
Uneven flow with multiple waterfall installations	Improper flow balance between the two waterfalls	Adjust the valves for each unit until the proper flow is achieved
