PLACEMENT OF THE DEVICE:
6.2.1.
The Quattro-DB
®
unit will typically best operate near the center of the
pond or from a point in the pond where all the cove banks can be seen in
a line of sight. The ultrasonic sound waves leave the device in a near
radial pattern that would form a circle around it.
6.2.2.
The range capability for the device for green algae and diatom type algae
is 150 meters (490 ft) in all directions. In this range the typical action on
these algae types is to cause a tear between the fluid pressure control
and the inner bladder wall called a plasmalemma. This disables the
algae
’s ability
to maintain internal fluid pressure which causes it to begin
to die.
6.2.3.
The range capability for blue-green algae with gas vesicles (easily broken
gas tubes in the algae cells) is approximately 400 meters (1310 ft) in all
directions. In this range the cells lose buoyancy and sink to the bottom.
The high frequency bandwidth of the device helps to break up the
colonial forms of these blue-green algae which will speed up their
control. Out of light, these algae will begin to lose the ability to create
sufficient nitrogen supply and causes them to fail.
6.2.4.
The sound will not penetrate natural barriers such as islands or weed
beds which will limit its capability behind such objects. The logical
placement point for most ponds is in the center, so that the sound can
travel to all banks with equal intensity. Oddly shaped ponds require a
strategy to determine the placement point. Some examples showing best
placement of the device are shown below.
6.2.5.
Connect the cable ends to the power supply module and to the Quattro-
DB
®
as indicated in the previous instructions. Place the unit at the
optimum point for your application. If unsure, please contact or email
customer support. Contact details are found in the Warranty Section.
Anchor the device by leaving some slack in the anchor to account for any
level changes that are typical for your water system. If this is a water
treatment plant application, please contact us for recommendations for
placement in your type of equipment.
