The rock trap is always recommended. It captures debris in the pipes and prevents debris from building up in the pool.

However, we do not recommend using the screen. Hair and other small debris can build up over time and impede water flow.

NOTE: During installation, do not “drag” the pipes along the ground or in the dirt. This fills the pipes with dirt and the waterfall will not work correctly after installation. (Yes, this really happens!)

Confirm that you can feel a small catch as the tool opens the latch.

Gently and slightly rotate the tool side to side to help catch the sliding door before pulling out.

The supply of water is not balanced correctly. To get equal flow from each waterfall unit, adjust the valves at each waterfall until the desired flow is achieved.

The door unlatching tool can be used to relieve binding inside the waterfall. Push the tool to the back of the side conduit and use it to reposition the LED strip inside the housing.

If the cable breaks or is pulled through while untied, try the following:

1. A shop vac can be used to guide it back through the channel.
   • Push the new pull-cable into the side channel making sure to keep it along the inside wall (the door opening tool can be used to help guide the pull-cable into the channel).
   • Place a shop vac hose over the opposite side channel opening and turn on the shop vac. The shop vac will “suck” the pull-cable through the waterfall. Re-attach to the LED strip.

If the pull-cable actually tears through the end of the LED strip, try the following:

1. The cable can be reattached by tying around the back of the black over-molded end. The door unlatching tool can be used to help guide the LED strip into the channel if it gets stuck.

You may have the incorrect power supply. A DC transformer/power supply purchased from CMP is required to activate the controller.

Wires may be crossed between the controller and waterfall. Sequence top to bottom should be as follows: White, Black, Green, Red. See detailed wiring diagram on the controller instructions or quick reference card.

‘Breaks’ in the sheeting could be due to the following:

• Debris may be caught in the lip.
  • Use the cleanout tool or a thin flat tool to clear the lip. DO NOT CUT ANY SUPPORTS.
  • Make sure the rock trap is installed properly and is not clogged.
• Check for burrs on supports in LED waterfalls.
  • A thin hacksaw blade may be used to carefully smooth edges as needed. REMEMBER NOT TO CUT THE SUPPORTS.
• GPM may be inaccurate. Too little flow or too much flow through the waterfall prevents proper water flow.
  • Reference the chart in the installation guide for proper GPM.
  • Also verify there are no air/leaks in the equipment or plumbing.
• Filter
  • The water line running to the waterfall must be filtered. We recommend the CMP Water Feature Filter or other cartridge filter.

Waterfalls 12″ and 18″ should be no more than 12″ above the waterline.

The ETL certified 100W power supply can control up to 12 ft of combined waterfalls. (Example: One power supply can support three 4ft waterfalls or six 2ft waterfalls.)

Yes! You can custom cut Natural Wonders® waterfalls for convex or concave curved installations.

To request a factory custom cut waterfall, please fill out a request form online, or download the custom cut waterfall form and fax/email the form back to CMP. Customer support will follow up to process your request.

Natural Wonders Waterfalls* can also be custom cut in the field. Never cut to within less than 1.5″ of the body.

*Natural Wonders Arch and Rainfall style waterfalls may not be cut.
