AERMASTER ULTIMATE SOLAR AERATOR
DW 7- DW 93/4HP COMPRESSOR

Shipment Delivery Inspection
The aerator unit was properly packaged, secured and accepted by the freight company prior to
shipment. It is the freight company’s responsibility to deliver without damage.
Apparent Damage or Loss
Upon delivery if the equipment or pallet indicates Damage in Transit, such goods should be
refused until freight company agent has been contacted.
Aeration unit pallet contents
•Solar panels
•Cabinet with instructions
•Diffusers (optional)
•Solar Racking with separate instructions
Important Safety Instructions:
•Reduce risk of bodily injury when handling bulky and/or heavy components by using a 2-
person
installation team. A second person should help to lift and handle these components.
•DANGER: RISK OF ELECTRIC SHOCK! DO NOT TOUCH ANY UNINSULATED
PARTS OF THE SOLAR PANEL, OUTPUT WIRING CONNECTED TO THE SOLAR
PANEL OR INSIDE BLACK ELECTRICAL BOX LOCATED IN THE CABINET.
•The solar panel can develop voltages greater than 42V DC, which poses a shock and/or
electrocution hazard. Outdoor Water Solutions recommends wearing electrically non-
conductive gloves when handling the Solar Panel’s output leads.
•To avoid shorting, the Solar Panel’s output does not cross a conductive object such as a
screw driver shaft.
•Install panel and wiring during DRY weather conditions. Never install system while the
weather is raining or in any way, precipitating.
Warnings:
•When preforming ANY maintenance or cleaning on solar panels or cabinet, the system
must be turned
off by the toggle switch located inside the cabinet.
•HIGH WIND AREA: Mount solar panels closer to ground to eliminate flexing of
panels and pole. Clear area from any trees/shrubs obstructing solar panels.

Installation Manual

•Monitor the panels. You don't need to do anything, but keep an eye on them. Make sure
your diffusers are producing water movement on the pond surface at clear sun peak.
•Keep the panels out of the shade. While you're at it, make sure that there are no new
shade issues that weren't there when the system was installed. We here at Outdoor
Water Solutions would never suggest you cut down a tree, but you may need to trim
them back. Shade on solar panels actually works exponentially, not proportionally, to
reduce panel output. So if 1/4 of the panel is shaded, you're not losing 1/4 of the output
for that panel, you're likely losing more than half.
How much sun is required
One common source of confusion with regards to solar powered aerators is the question of how
much sun is
required to successfully power the aerator? Does it have to be perfectly sunny? What if a cloud
blocks the sun? The answer is... it depends. The sun's energy varies throughout the day and at
some point in the day (usually around 12pm), the sun will reach its peak intensity. If it's a clear
day (i.e. no clouds), this is the point at which a solar powered aerator will reach its peak output.
As the day progresses and the sun gets lower in the sky, the power output of a solar panel will
naturally decrease until dark at which point power output will halt altogether. In the same way,
anything that obstructs the sun during the day, such as clouds, trees and buildings, will also have
an effect on the output of the panel. For example, if the sun is obstructed by some light cloud
cover, it is still possible, depending on the time of day, to achieve greater than 50% of the solar
devices direct-solar output. In terms of an aeration system, that means you could still achieve a
reasonable flow rate as long as the clouds don't get too thick, or the sun isn't too low in the sky.

Solar Panels Wired in Series-(amount of panels may vary)
When solar panels are wired in series, the positive terminal of one solar panel is wired to the
negative terminal of the next solar panel. When panels are connected in series:
•Voltage accumulates (adds) for each panel in series.
•Wattage accumulates (adds) for each panel in series.
Current (Amps) remains the same as a single panel in the series
Grounding System
System comes with grounding clamp. Attach ground clamp to solar panel pole see photo below.

Installation Instructions:
Attach your airline to each of the airlines exiting the AerMaster cabinet. Run each airline out to
the place in the pond where you want your diffuser and attach your diffuser. For diffusers with a
base, lower the diffuser down to the bottom of the pond. Using a rope can help to keep the
diffuser and base upright. You don’t have to tie the rope on, just fold the rope in half, lower the
diffuser, then pull the rope up by pulling on one half.
If your diffuser does not have a base (rubber membrane diffuser or ceramic air stone), then
inserting the diffuser into a bucket can help keep it out of the mud and muck on the bottom.
Adding 3-5 lbs. of sand or rock to the bottom of the bucket prior to inserting your diffuser helps
sink and stabilize your bucket. Note: Teflon tape is recommended, but not required for
threaded connections. If you have a rubber membrane diffuser with the airline coming off
of the side, you can drill a hole in the side of the bucket and run your airline thru the side.
We also suggest installing your diffuser into the deep part of the pond to ensure complete
circulation of your water. The exception to this would be if you’re wanting to keep the water
open for watering livestock in the winter, then you can put the diffuser closer to the shoreline (or
move it there in the fall). You can also place the diffuser in a more shallow area if you are in a
northern climate and have trout, walleye, Northern pike or Muskie in the pond and want the deep
parts of the pond to remain colder in the summer months.
The use of OWS Weighted Air Line will help keep the airline submerged and on the bottom of
the pond. In the absence of using weighted airline, tie rebar, bricks, blocks, etc. to non-weighted
airline to help keep it submerged.
Note: Air will travel to the point of least resistance or to the shallow diffusers first. Adjusting
the airflow so that it goes to the deepest diffusers is usually required.
First time start up
System comes from OWS with the system OFF.
#1 After aeration system is completely installed and panels are connected.
On the yellow box unscrew (4) flat head screws removing cover on yellow box.
#2 Once cover is removed turn toggle switch to the ON position. (Do not
change any factory settings). Lights will turn on at the front of the yellow box.
