GENERAL INFORMATION
Read instructions thoroughly prior to assembly and installation. All Clear products are factory
adjusted for optimal nanobubble production. Do not adjust factory setpoints.
LOCATION REQUIREMENTS
Carefully select the Clear installation location based on the requirements specified in this section.
Locate the Clear as close to the waterbody as possible in a 5 ft x 5 ft (1.5 m x 1.5 m) open area
of level ground. Use the guidelines shown in Figures 1 and 2 to locate the intake structure.
Ensure that the intake structure location is free of weeds and debris. Do not locate the intake
structure in an area where leaves or other floatable debris tend to accumulate. Where possible,
locate the intake structure several feet (a couple of meters) from shore.

For Clear power input, suction and discharge pipe, and installation elevation requirements refer
to Tables 1, 2, and 3, respectively. Tables are divided by pump type, if applicable.
Failure to install the Clear within the limits specified in Tables 1, 2 and 3 may void the
system warranty and result in poor nanobubble production and pump cavitation.

Pipe lengths and unit elevations can play an important role in the performance of the pump and
the unit as a whole. Refer to the Appendix for additional detail regarding the recommended
operating envelope for these units.
While minimizing the elevation of the unit from the water surface is the key to optimized
performance, special measures must be taken to reduce the chances of water ingress
into the unit (flooding). For example, if the water level changes throughout the year, the
installation elevation must be above the max water level. If the water ingress is
unpredictable, use barriers around the unit to reduce the chance of flooding.

All parts necessary to assemble up to 40 linear feet (12 linear meters), each, of suction and
discharge piping are provided with purchase of a Clear Installation Kit. The actual length of pipe
required will vary by installation. Additional pipe lengths may be purchased with the Clear in
10-foot (3-meter) increments.
The Clear Installation Kit can only be shipped within the United States and Canada. Refer to
Table 5 for the Clear Installation Kit parts list. Clear Installation Kit parts and additional suction
and discharge pipe can be purchased at most hardware stores. For pipe assembly, use only
Schedule 40 polyvinyl chloride (PVC) pipe and fittings and Oatey Rain-R-Shine Medium
Blue PVC Cement or equivalent PVC cement formulated for wet conditions and fast
installation.
Prior to installation, verify all parts listed in Tables 4 and 5 are present. Not all pipe and fittings
provided in the Clear Installation Kit will be required for all installations.

INSTALLATION GUIDELINES
The unique site conditions for each waterbody should be carefully considered when identifying
the Clear installation location. Refer to the Location Requirements section of this guide for
addition details.
The guidelines herein are recommended for calm waterbodies with intake structure depths less
than 10 ft (3 m). For deeper water intakes or high current waterbodies, contact a Moleaer
sales representative or call [phone] prior to purchasing a Clear.
Upon delivery, unscrew the shipping screws to remove the Clear from the shipping crate. Inspect
the Clear for any damage or loose parts that may have occurred during transport. Hand tighten
any loose parts.
Installation Parts and Materials
The parts and materials required to install the Clear include:
•A shovel
•25 cubic feet (0.7 cubic meters) of all-purpose gravel
•PVC saw
•PVC pipe primer and PVC pipe cement
•Clear Installation Kit or installation kit parts listed in Table 5
Pipe Assembly
Completely bury or submerge all PVC pipe and fittings to avoid ultraviolet (UV)
degradation. All PVC pipe connections must be solvent welded using PVC cement. Use
only Schedule 40 polyvinyl chloride (PVC) pipe and fittings. Use only PVC cement formulated for
wet condition and fast installation to connect PVC pipe to PVC fittings. Do not use black,
acrylonitrile butadiene styrene (ABS) piping or mix ABS pipe or fittings with PVC pipe or fittings.
All PVC pipe connections must be airtight and leakproof. Failure to provide airtight suction
pipe connections may negatively impact nanobubble generator performance. Large
bubbles visible at the pump strainer basket is an indication of suction pipe leaks. Difficulty with
pump priming may also be an indication of suction pipe leaks. Check and correct for all suction
and discharge pipe leaks prior to burying or submerging pipe.
Proper technique must be used when gluing PVC pipe and fittings to ensure an airtight, leakproof
connection. For proper technique, refer to the Appendix. Allow for proper cure time to lapse
before wet testing suction and discharge pipes. Refer to Appendix, Item 8 for cure times.
Clear Installation
The installation diagrams for the Clear are shown in Figures 3 and 4. Using a shovel, dig a hole
approximately 5 ft (1.5 m) Long (L) x 5 ft (1.5 m) Wide (W) x 1 ft (0.3 m) Deep (D). The Clear will
be installed with the pressure gauges facing away from the waterbody. Near the edge of the hole

that is closest to the waterbody, dig out a portion of the pipe trench that is long and deep enough
to hold the first segment of suction and discharge pipe.
Refer to the pipe connections extending from the base of the Clear that are shown in Figure 3.
Using PVC primer and cement, glue elbows to the first straight, horizontal pipe segments of
suction and discharge piping and lay these pipe segments in the pipe trench with the elbows
facing up. Refer to Figure 5 for Clear enclosure dimensions and pipe penetration locations to
properly position the elbows.
Using PVC pipe primer and cement, glue a segment of straight pipe long enough to vertically
connect the pipe connections at the base of the Clear to the elbows positioned in the hole. Glue
one end of the vertical pipe to the suction elbow in the trench and the other end to a coupling.
Repeat these steps for the vertical segment of discharge pipe. Do not bury horizontal pipes until
the Clear is installed and has passed leak inspection and wet testing.
Once the vertical suction and discharge pipes and first segments of horizontal suction and
discharge pipes are glued in position, fill the hole with gravel until the reducing couplers are
partially buried. Level the gravel. Verify the reducing couplers are positioned correctly to line up
with the pipe connections extending from the base of the Clear.
The pipe connections at the base of the Clear are grooved for factory testing. The grooves will
not interfere with the gluing of PVC connections. Using PVC primer and cement, coat the pipe
connections at the base of the Clear and the reducing couplers with cement and then place the
Clear on the gravel bed, making sure that the pipe connections are aligned with and firmly glued
into the coupling.

Suction Piping and Intake Structure Installation
Locate and install the intake structure and suction pipe following the recommendations detailed
in Figures 1, 2, and 6, and in the Appendix. Use available fittings as necessary to route the
suction piping from the Clear to the waterbody. Do not remove the bell end of the PVC pipe. The
bell end can be used as a coupling for connecting straight pipe segments.
