SINGULAIR
®
CONTROL CENTER
Every Singulair aerator is supplied with a prewired
electrical control center to permit fully automatic operation.
The control center is contained in a sealed corrosion
resistant enclosure for your safety and the protection of
components and wiring. The control center should be
located so the red warning light can be seen and the
audible alarm heard. It should be mounted to minimize
exposure to direct sunlight, freezing rain or conditions
that might prevent routine inspection or access. If an
electrical overload occurs for any reason, the red warning
light will glow and the audible alarm will sound. To shut
off the alarms and restart the aerator, push the reset
button on the control center cover. This should reset the
circuit breaker and allow the aerator to resume normal
operation. If the alarms do not shut off after depressing
the reset button or if the breaker continues to trip, call the
local Singulair distributor.
TIME CLOCK
Each control center is supplied with an adjustable time
clock that determines the operating cycle of the aerator.
The time clock will not permit the aerator to run less than
30 minutes out of each hour and is adjustable in 5 minute
increments up to 55 minutes per hour. Full time
operation is achieved by moving the selector switch to the
“continuous” position. The performance of the Singulair
system has been certified to meet NSF/ANSI Standard 40
effluent quality requirements and USEPA secondary
treatment guidelines at the minimum time clock setting.
The time clock is factory preset and should not be adjusted
by the owner. Your factory-trained Norweco distributor
will make necessary adjustments under the specific
direction and authorization of the local regulatory agency.
If you feel an adjustment is necessary, contact your
local distributor.
BIO-STATIC
®
SLUDGE RETURN
Each Bio-Static sludge return is securely installed in the
aeration/clarification chamber wall to provide return of settled
solids. Aeration chamber hydraulic currents enter the sludge
return(s) and are directed through the Bio-Static device into
the clarification chamber. The hydraulic currents containing
resuspended sludge are directed through the clarification
chamber inlet zone and back to the aeration chamber
for additional treatment. The Bio-Static sludge return
accomplishes resuspension and return of settled solids
without disturbing the contents of the clarification chamber.
It has no moving parts and does not require service but its
operation will be checked by your local distributor during
each semi-annual service inspection.
BIO-KINETIC
®
SYSTEM
Bio-Kinetic systems provide non-mechanical flow
equalization through all plant processes. The Bio-Kinetic
system contains 3 separate filtration zones, 8 independent
settling zones, optional chlorination and dechlorination tablet
feed systems and serves as its own chlorine contact
chamber. When used with Blue Crystal residential
disinfecting tablets, the performance of the Bio-Kinetic
system as a chlorination device is certified to NSF/ANSI
Standard 46, Section 11. All components are manufactured
from plastic, stainless steel or rubber. Do not remove a
Bio-Kinetic system from the clarification chamber without
disengaging the locking lugs and pumping out the internal
chambers. Your local distributor has the necessary training,
tools and equipment for removal and cleaning. If your
Bio-Kinetic system is in need of service contact your local
distributor. During each semi-annual service inspection your
local distributor will remove and clean the Bio-Kinetic system
or replace it with a unit from their service stock.
