B. Balancing Diffusers
1.
ALL VALVES MUST BE IN OPEN (VERTICAL) POSITION BEFORE STARTING
. (See below)
2. Turn the Main Switch up to
ON.
3. The Air Pressure Gauge reading is at the minimum at this point.
4. Beginning with the Diffuser Manifold Bases in the
shallowest
depths, start turning clockwise (closing) the valves until
air begins to rise from the deeper bases. Continue slowly adjusting the valves from the shallowest bases to the deepest
until the diffused air pattern rising from each base appears to be equal. This will take some trial and error.
The valve supplying the Diffuser Manifold Base deepest in the water will remain fully open.
5.
IMPORTANT:
While balancing the diffused air patterns in the water attempt to maintain the
lowest possible
reading
on the air pressure gauge. Keeping the air pressure reading low as possible translates to the highest possible volume
(CFM) of air being distributed to the Diffuser Manifold Bases.
MANIFOLD VALVES SHOWN FULLY OPEN IN THE VERTICAL POSITION
IMPORTANT START-UP WARNING: RISK OF FISH KILL
When the oxygen level is less than 1PPM at the depth of the Diffuser Base, avoid the rapid release of noxious gas having
the potential to kill fish by adhering to the Otterbine recommended operation guideline below.
