Installation:
There are many ways to install you new SCWD. The following instructions reflect the preferred method of installation. In addition, even though your new SCWD is not overly sensitive to the normal particulate and debris found in aquarium systems, to ensure long life, water must be filtered prior to entering the SCWD.
- Measure and cut two pieces of 3/4" or 1" (ID) hose for the two outlets. For best results, it is strongly recommended that both outlet hoses are cut equal in length, leaving the SCWD centered between the two outlets.
- Measure and cut one piece of 3/4" or 1" (ID) hose that will be connected to the water pump, canister filter, or powerhead outlet at one end and the SCWD inlet on the other. It is recommended that an inline valve be installed between the water pump and the SCWD to allow for flow adjustment, and for ease of removal and cleaning of the outlet hoses if required.
- Install each hose on each outlet of the SCWD by applying firm, but even pressure, until each hose is fully seated. It is recommended at this point that you install worm clamps for added protection against leaks and the possibility of the hose coming loose. Do not over-tighten the worm clamps.
- Install the inlet hose using the same operations noted in Step 3, paying close attention not to exert too much force on the nipple.
- Once all hoses are mounted and clamped, you are now ready to install the outlet elbows and nozzles on each end of the outlet hoses. By combining rigid elbows to form an angle over the aquarium side you can adjust the position of the outlet nozzles to give you the desired current affect. The configuration of the elbow is such that it will hang over the back of the tank on both sides like an upside down "U." At this time, you should support the SCWD by mounting or hanging the SCWD from the back of your tank using bendable wire.
- Connect the inlet hose with the inline valve to your pump, canister filter, or powerhead outlet. Be sure to use a worm clamp to avoid any potential leakage.
Operation:
- Make certain the SCWD is securely installed before operation. Open the in-line valve between the water pump and your SCWD so that it is approximately half open. This is as precautionary step to prevent a full force surge to the SCWD when using some of higher volume and pressure pumps.
- Apply power to the water pump. Verify water outlets are expelling water and that there are no leaks at any of the connections. Verify that the device is switching water flow between the two outlets. Now, open the in-line valve to your desired flow.
Remember that switching speed and current duration are dependent on the volume of water flowing through the SCWD. Higher volume pumps will naturally cause a quicker switching response than lower volume pumps. By adjusting your inline valve you will be able to regulate both the amount of flow and the switching speed.
Troubleshooting
Symptom: Switching speed too slow.
Remedy: Check pump for proper flow/pressure rating.
Symptom: Switching speed inconsistent.
Remedy: Check hoses for algae and slime obstructions.
Symptom: SCWD is noisy or stops abruptly, stops and starts sporadically.
Remedy: Foreign debris is lodged in switching mechanism. Flush out unit to dislodge debris. Verify pre-filter is installed and is not clogged or restricting flow.

Instructions
Special Note: Although there are many different ways to install your new SCWD, the following instructions reflect the most common method of installation. In addition, even though your new SCWD is not overly sensitive to the normal particulate and debris found in aquarium systems, to ensure long life, it is strongly recommended that water be filtered prior to entering the SCWD.
Installation
Your new SCWD can accommodate many installation options to support various pump outputs and aquarium configurations. The SCWD can be mounted in-line using PVC pipe and fittings, or can be installed using vinyl tubing and barbed fittings. Please follow the steps provided below to install your new SCWD.
- Planning is Key. Identify the location the SCWD will be mounted. Consider mounting the SCWD in a location that will allow for ease of access to the SCWD. Mounting the SCWD behind or under the aquarium in the stand or cabinet will provide for ease of adjustments and cleaning.
- Decide whether you are going to "hard" plumb using PVC piping or "soft" plumb using vinyl tubing.
- Caution: As in any external pump or filter, when mounting the SCWD where it is lower than the aquarium water line, performing maintenance without closing off the water to the SCWD will result in water backflow/siphoning, resulting in water leakage or flooding, which can cause extensive damage and present a safety hazard. Please take necessary precautions by installing adequate valves to prevent potential flooding.
- Caution: Although your new SCWD is built to the highest quality standards, it is recommended that care be exercised when installing fittings so as not to damage the inlets and outlet ports. Use Teflon® tape. Do not use pipe dope.
PVC Installation (1" Model)
Using 1" PVC pipe and fittings, plumb in-line as you would normally, using the appropriate materials and tools. To assure a watertight seal, please be sure to use Teflon® tape for all threaded fittings and the proper PVC cement for all slip fit connections. It is also recommended that in-line ball valves and union fittings be installed between the SCWD and water pump and between the SCWD and each outlet to allow for removal and cleaning (if required) and to prevent chance of flooding during maintenance.
- Install 1 inch threaded fittings into the SCWD inlet and outlet ports using Teflon® tape to assure proper seal. Wrap the threaded end of the fitting clockwise three times. Be careful not to over tighten.
- Measure and cut two pieces of 1 inch PVC pipe for the two outlets. For best results, it is recommended that both outlet pipes are cut equal in length, leaving the SCWD centered between the two outlet ports. Keeping the two pipes equidistant provides consistent switching duration between the two outlet ports.
- Install one pipe on each outlet of the SCWD by attaching 1 inch PVC pipe to each of the fittings using appropriate PVC cement, paying close attention to prevent any cement from entering the SCWD through the outlet ports.
- Measure and cut one piece of 1 inch PVC pipe that will be connected to the water pump, canister filter, or power head outlet at one end and the SCWD inlet at the other end. It is recommended that an in-line ball valve be installed between the SCWD and water pump to allow for flow adjustments and for ease of removal and cleaning.
- Install the inlet pipe by attaching 1 inch PVC pipe to the fitting using appropriate PVC cement, paying close attention to prevent any cement from entering the SCWD through the inlet port.
- Once all pipes and valves are in place, you are now ready to install the outlets elbows and nozzles on each end of the outlet pipes. By combining 1 inch PVC 90 degree elbows to form an angle over the aquarium side, you can adjust the position of the outlet nozzles to give you the desired current effect. The configuration of the elbow is such that it will hang over the back of the aquarium on both sides like an upside down "U". Please note: There are other ways to plumb this, including the use of preformed U-tubes and other such fittings.
Vinyl Tubing Installation (1" Model)
Using 1 inch (ID) vinyl tubing and fitting, plumb in-line as you would normally, using the appropriate materials and tools. To assure a watertight seal, please be sure to use Teflon® tape for all threaded fittings and the proper PVC cement for all slip fit connections. It is also recommended that in-line ball valves and union fittings be installed between the SCWD and water pump and between the SCWD and each outlet to allow for removal and cleaning (if required) and to prevent chance of flooding during maintenance.
- Install 1 inch threaded hose barbed fitting into the SCWD inlet and each of the outlet ports using Teflon® tape to assure a proper seal. Wrap the threaded end of each of the barb fitting clockwise three times. Be careful not to over tighten.
- Measure and cut two pieces of 1 inch vinyl tubing for the two outlets. For best results, it is recommended that both outlet pipes are cut equal in length, leaving the SCWD centered between the two outlet ports. Keeping the two pipes equidistant provides consistent switching duration between the two outlet ports.
- Measure and cut one piece of 1 inch vinyl tubing that will be connected to the water pump, canister filter, or power head outlet at one end and the SCWD inlet at the other end. It is recommended that an in-line ball valve be installed between the SCWD and water pump to allow for flow adjustment and for ease of removal and cleaning. NOTE: To avoid potential leakage, for all connections, please be sure to use a metal worm clamp for external mounting and a plastic click type clamp for installations that are submerged. Helpful Tip: To facilitate easy installation, moisten the end of each hose with hot water.
- Install one hose on each outlet of the SCWD by applying firm but even pressure until each hose is fully seated on the barbed fitting. It is recommended at this point that you install the appropriate hose clamps for added protection against leaks and the possibility of the hose coming loose. Do not over tighten the clamps.
- Once all hoses and valves are in place, you are now ready to install the outlet elbows and nozzles on each end of the outlet hoses. By combining rigid elbows to form an angle over the aquarium side, you can adjust the position of the outlet nozzles to give you the desired current effect. The configuration of the elbow is such that it will hang over the back of the aquarium on both sides like an upside down "U". Please note: There are other ways to plumb this, including the use of preformed U-tubes and other such fittings.
Operation
Congratulations! You are ready to begin operation of the #1 wave maker and bring your aquarium to life.
- Open the valve between the water pump and your SCWD so that it is approximately half open. This is a precautionary step to prevent a full force surge to the SCWD when using some of the higher volume and pressure pumps.
- Apply power to the water pump. Verify water outlets are expelling water and there are no leaks at any of the connections. Verify that the device is switching water flow between the two outlets.
- Adjust the valve to desired flow. Watch your fish and corals come alive.
Helpful Tip: Switching speed and current duration is dependent on the volume of water flowing through the SCWD. Higher volume pumps will naturally cause a quicker switching response than lower volume pumps. By adjusting your inline valve, you will be able to regulate both the amount of flow and the switching speed.
Maintenance (1" Model)
Removal of Carrier and Drive Assembly
Provided all instructions and tips are followed, your SCWD was designed to be virtually trouble free. It is recommended, however, that you inspect your SCWD for general serviceability whenever maintaining your aquarium. Inspect your SCWD and all pipes, hoses, valves, and their connections for leaks. Also, to assure proper water flow, inspect inlet and outlet hoses for algae and slime buildup and clean is required.
Cleaning the inside of the 1" SCWD is possible but should not be required provided a pre-filter is used. To clean, please follow the simple steps below. Helpful Tip: To prevent harm to fish and invertebrates, never use soap or detergents when cleaning your aquarium and supporting equipment. Do not subject your SCWD to intense heat such as boiling water or a dishwasher, as it will cause parts to warp.
- Remove SCWD Cap by turning counterclockwise.
- Remove O-Ring from Cap and inspect O-Ring for wear or cracking.
- Unlock the Swing Locks at both sides of the Carrier shoulders. To remove the carrier assembly without removing the gate, you will need access to the Swing Locks. Depending on the orientation of the Gate, you may need to turn the Gate counterclockwise enough to gain access to the Swing Locks. With your finger and using the small raised tab on the Swing Lock, slide the Swing Lock to either side making sure the Swing Locks are clear and out of the way.
- Gently pull out the Carrier and Drive Assembly.
- Inspect inside of Housing, including Housing Channel Rails for debris. Flush out Housing with fresh water as required.
Installing Carrier and Drive Assembly (1" Model)
To re-install the Carrier and Drive Assembly, please follow the simple steps below.
- Making sure that Swing Locks are off to the side and completely clear, slide the Carrier and Drive Assembly into both Channel Rails in Housing. Please Note: Because the Drive Assembly is secured to the Carrier through a slight friction fit, please make sure you seat the Carrier in the Housing by pressing down on the Carrier and not the Drive Assembly or Gate. Otherwise you may force the Drive Assembly out of the Carrier from below. Please make sure the Carrier is installed in both Channels and is fully seated, verifying the top Carrier surface is flush with the top of the Channel Rail surface.
- Once the Carrier and Drive Assembly are in place, move the Swing Locks into the locking position, making sure they are flush with the top of the Carrier and the small hole on the Swing Lock is over the Locking Bumps on the Carrier. To allow access to the Swing Locks, depending on the orientation of the Gates, you may need to turn the gate counter clockwise enough to gain access to the Swing Locks. Once you have access, with your finger and using the small raised tab on the Swing Lock, slide the Swing Lock to the locking position. Remember to re-tighten the Gate if you had to move it to gain access to the Swing Locks. Do not over tighten.
- Using food grade lubricant, apply a thin coating to entire surface of the O-Ring.
- Place lubricated O-Ring in Channel of Housing Cap, making sure the O-Ring is properly seated.
- Place Cap on the SCWD Housing and hand tighten Cap to Housing, turning clockwise, making sure not to over tighten. Tighten the Cap until the O-Ring makes contact with the Housing and causes a slight compression of O-Ring.
Removal of Drive Assembly from Carrier (1" Model)
To remove the Drive Assembly from the Carrier, please follow the simple steps below.
- Once the Carrier and Drive Assembly have been removed from the Housing, remove the Gate from the Drive Assembly's threaded shaft by turning counterclockwise.
- Gently slide the Drive Assembly out from the bottom of the Carrier. Slight resistance from the Carrier to Drive Assembly interface is normal. Depending on the amount of debris lodged between the Drive Assembly and Carrier, additional force or flushing with fresh water may be required to free the Drive Assembly from the Carrier.
- Inspect inside of Carrier for debris. Flush out Carrier with fresh water as required. Helpful Tip: To prevent harm to fish and invertebrates, never use soap or detergents when cleaning your aquarium and supporting equipment. Do not subject your SCWD to intense heat such as boiling water or a dishwasher, as it will cause parts to warp.
Assembly of Gate, Carrier, and Drive Assembly (1" Model)
To re-assemble the Gate, Carrier, and Drive Assembly please follow the simple steps below.
- Slide the Drive Assembly into the Carrier from the bottom side up, until fully seated, making sure Carrier Notches are aligned with Drive Snap Locks at bottom of Drive Assembly. Please Note: There may be slight resistance due to the design of the circular Carrier. This is to hold the Drive Assembly in place during operation and is normal.
- Install the Gate onto the Drive Assembly's threaded shaft. By turning clockwise, screw the Gate onto the Drive Assembly's threaded shaft, making sure not to cross-thread the Gate. Keep tightening until the Gate is fully seated and has covered the hex shaped section of the threaded shaft. Caution: Do not over tighten. You will feel increased resistance when the Gate is seated correctly.
Trouble Shooting
Most problems related to the proper functioning of the SCWD are attributed to poor, or lack of filtered water entering the SCWD. Water should always be filtered prior to entering the SCWD. There are very few things that can go wrong with the SCWD. If you should experience difficulties, please use the recommendations for the specific conditions listed below.
Symptoms
- Switching speed too slow.
- Switching speed inconsistent or stops and starts sporadically.
- SCWD is noisy or stops abruptly.
Remedies
- Check pump for proper flow/pressure rating.
- Check hoses and fittings for algae, slim, and other obstructions.
- Verify pre-filter is installed and not clogged or restricting flow.
- Foreign debris lodged in switching mechanism. Flush out or clean SCWD to dislodge debris.
- For 1" Models, verify Carrier, Gate, and Drive Assembly are seated properly in Housing and Swing Locks are in the locked position.
General Information
The 1" SCWD from 3iQ Ventures was designed and built to the highest standards of quality and reliability. Designed with large aquarium and pond applications in mind, this device will provide increased water movement at higher volume rates. With its 1" standard thread inlet and outlets, the device can be hard plumbed with PVC fittings, or soft plumbed using barbed fittings. The cap is removable, allowing for easy maintenance. With the new drive design, the 1" SCWD will run with pump applications from 500gph to 3,500 gph. Besides the obvious physical differences, the design of the 1" SCWD is targeted toward high water volume output with a substantially increased switching duration. A longer interval between switching cycles means better water movement penetration to the extreme areas of large aquariums, providing your corals, invertebrates, and plants with longer periods of time between shifting currents.
The 1" SCWD comes preassembled with the standard drive assembly installed. With its efficient new design, the 1" SCWD allows hobbyists to switch out drive assemblies and diverters to customize the output flow and switching duration to meet their specific needs.
