Owner’s Manual with the owner. If lint, grease, scouring
pads, diapers, sanitary napkins, cotton balls, cotton
swabs,cleaning rags, dental floss, strings, cigarette filters,
rubber or plastic products, paints, thinning agents or other
harsh chemicals are discovered in the system, the owner
shouldbe cautioned regarding proper use of the system.
WHAT TO PUMP
When pumping is required, normally it is necessary to
pumponlythe pretreatmentchamberifthesystem hasbeen
serviced at regular 6-month intervals. If service has been
interruptedfor anextendedperiod of time,or if mudor toxic
material is present, it may be necessary to pump out the
entire system. When pumping, it is not necessary to wash
down the compartments unless significant quantities of
grease, hair, fibers, mud, toxic substances or biologically
untreatable materials are present. The capacity of the
pretreatment chamber is 450 gallons. When pumping the
pretreatment chamber, an additional 400 gallons will be
removedfrom the aeration and clarification chambers until
theliquid leveldropsbelow thetransferport invert. Atotalof
850gallonswillberemovedwhenthepretreatment chamber

CAUTION: Afterpumpinganyportion oftheSingulairGreen
tank, it is essential to immediately refill each chamber with
clear water to the design flow line. The water must be free
of leaves, mud, grit or other materials that might interfere
withsystem operation. Dewatering andleavingthe system
empty will affect tank integrity and void the warranty.
HOW TO PUMP THE SYSTEM
A complete Singulair Green system pumping procedure is
listedbelow. Priortopumping, contactthe Singulair Green
dealertoobtaincompleteinformationonequipmentremoval
and reinstallation. Failure to properly remove and reinstall
equipment and access covers during tank pumping may
resultin damage to the system and will void the warranty.
1. If any portion of the Singulair Green system requires
pumping, contact a tank pumping service licensed by
the local regulatory agency. The septage or biosolids

3. For pumping the pretreatment chamber only, remove
all three access covers and insert a suction hose into
the pretreatment chamber. Lower the hose until it
contacts the bottom of the tank. Withdraw the hose
approximately 2" and connect the opposite end to the
pumpbeingusedtoevacuatethechamber. Donot allow
the hose to rest on the bottom of the tank.
4. Break up the scum mat to facilitate pumping. Activate

It is not necessary to wash down the
sidewalls or tank bottom.

6. If special circumstances require the total system to be
pumped, contact the local Singulair Green
dealer. The aerator and Bio-Kinetic system must be
removed for full access to all chambers and to
preventdamageto components. Onlythefactorytrained
Singulair Green dealer should attempt to remove and
reinstallthe equipment.
NOTE: Access to the contents of the aeration and
clarificationchambersofSingulairGreensystemsshould
bemade only through an aerator mounting riser. Never
insert the hose through the Bio-Kinetic system
mountingriser.
7. A Singulair Green system that has been inactive for an
extended period of time or that has accumulated mud
or dirt during installation may have to be washed down
with fresh water and pumped out. This process may
haveto be repeatedforproper system operation.
8. After pumping, fill all chambers to capacity with water.
Return the aerator, Bio-Kinetic system and all access
covers to their proper locations, as outlined in the
Singulair Green Service Manual. Be sure each control
center selector switch is in the “on” position, and each
enclosureissecuredwith a tamper evident seal.
Following tank pumping, no other system adjustments are
necessary for proper biological treatment to continue.
Semi-annual service inspections by a factory-trained
Norwecoservice technician should be conducted to insure
longterm system performance.
