Parts, Tools, and Materials
The following is a list of various parts, materials and tools
required for the installation and startup of the equipment.
As each installation is unique, this is not an exhaustive but
a recommended list.
•PVC Glue
•PVC saw
•PVC pipe primer and PVC pipe cement
•PVC Pipe or hose and fittings to connect to the
tank.
•Wrench
•Pliers
•Level
•Smoke pen for checking leaks on the suction line
•Spray bottle of soapy water for detecting air tube
leaks
•Miscellaneous items including tape measure,
marking pencil, shop towels for cleaning, etc.
Pipe Assembly
Completely bury or submerge all PVC pipes 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 conditions
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 are 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 the 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 before wet testing suction and discharge pipes.
Piping
Pipe lengths and unit elevation can play an important role
in the performance of the unit. Standard Installation should
be no higher than 6’ above the water surface, and the total
length of pipe above the water surface should be less than
10’, but in no case longer than 30’. In this Standard
Installation, priming of the pump is expected to require no
more than 5 minutes if there are 10’ of pipe above the water
surface, and will be considerably longer if the length of pipe
above the water surface is between 10' and 30’ in length.
Locate and install the discharge pipe following the
recommendations detailed in Figures 4 and 5.
The intake and discharge ports on the Kingfisher are both
1.5” (63 mm) union fittings.
Locate and install the intake structure and suction pipe
following the recommendations detailed in Figures 4 and 5.
Use available fittings as necessary to route the suction
piping from the unit 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.
Install the included intake screen at the suction end of the
pipe to stop large debris from entering the system. Ensure
that the intake screen is fully submerged but elevated from
the lake bottom to avoid sediment buildup. Ensure that the
suction line is continuously rising from the water body to the
inlet of the unit. High spots in the suction line may trap air
and prevent the pump from self-priming properly.
It is recommended to install a swing-style check valve to
facilitate faster priming of the pump during start-up. If a
check valve (not included) is installed on the suction line,
ensure that it is installed with the flow arrow in the direction
of suction flow so as not to restrict the flow of water to the
pump.
Locate and install the discharge pipe following the
recommendations detailed in Figures 1 and 2. Use
available fittings as necessary to route the discharge piping
from the unit to the waterbody. Discharge should be firmly
fixed and pointed towards the center of the water body to
avoid causing erosion. Do not remove the bell end of the
PVC pipe. The bell end can be used as a coupling for
connecting straight pipe segments.
Do not bury either suction or discharge pipe until the system
has been wet tested and is free of leaks.
Power Input
Extension cord use is hazardous and should be
avoided. In certain jurisdictions, permanent
installation using an extension cord is not
permitted. Check with your local electrical code.
Step 1. The Kingfisher requires a dedicated, weather-
resistant power receptacle. After starting the Kingfisher,
perform a voltage drop test to verify voltage is within normal
limits.
