Big Dipper Internal Strainer System Overview
The Thermaco, Inc. Big Dipper®Automatic Grease and Oils
Removal System removes free-oating grease & oils from
kitchen drain water ows. As most food service facility manag-
ers already know, grease buildup within a building’s plumbing
drainage system is a major cause of problems due to drain line
blockages. These problems jeopardize normal operations as
well as create health and safety hazards within the facility itself.
The proper installation of a Big Dipper System can reduce or
eliminate grease problems. Use of the Big Dipper assures
minimization and/or elimination of costly sewer surcharges and
nes through efcient separation and removal of free-oating
grease & oils. In addition, the Big Dipper also helps reduce or
eliminate pumping and disposal costs associated with conventional grease separators or intercep-
tors. The recovered grease & oils are substantially water-free and are suitable for recycling by local
rendering and/or biodiesel companies.
The Big Dipper system is an automatic, self-cleaning device. As greasy kitchen efuent drains from
kitchen xtures, the unit contains the grease & oils. These separate from the efuent and rise to the
surface of the separator tank. The unit automatically skims the contained grease & oils and transfers
the grease & oils to a collection container. A digital control maintains the self cleaning operation,
activating the skimming wheel periodically based on the setting chosen. Only the “cleaned” water
exits the unit and ows into the facility drain lines. The Big Dipper IS automatic systems operate most
efciently when servicing single xtures such as a 1 to 3-compartment sink or a pre-rinse station.
The Big Dipper system’s compact footprint allows installation directly at the source where grease
problems originate. The system design also allows easy maintenance and operation requiring only
a minimal amount of daily and weekly maintenance to maintain peak operating performance.
The Big Dipper system design allows for maximum installation exibility. Reversing the system op-
eration is a simple as rotating the cover assembly of the unit.
Hydromechanical grease interceptors (formerly referred to as grease traps), grease separators, au-
tomatic recovery units, grease removal devices and other similar plumbing devices receiving kitchen
ows from sinks, oor drains, woks and other food bearing sources may generate odors. The 51k
Series Big Dipper has been designed to seal in odors and prevent them from leaking into the kitchen
through the tank lids. It does not prevent odors related to the rest of the plumbing system including
but not limited to: open oor drains, air gaps, external solids straining devices, improper venting, and
odors generated elsewhere in the plumbing system. These odors are usually prevented by good area
ventilation, frequent uid inputs, good product maintenance practices and proper product installa-
tion. Additional pretreatment steps not performed by the Big Dipper automatic grease interceptor,
including aeration, chlorination, improved area ventilation and additional maintenance control, may
be needed at some sites.

System Maintenance
*CAUTION! DISCONNECT POWER TO UNIT BEFORE CLEANING
to prevent damage to the unit and personal injury
*NOTE: Before energizing unit after cleaning, ll tank with water
to protect wipers and heater from damage
Big Dipper®Internal Strainer (IS) System Maintenance
Daily Maintenance:
(A) Empty the clear plastic grease/oils collection container (located beside the unit) prior to its be-
coming full once each day. The Big Dipper recovers grease and oil virtually water-free so that they
can be recycled. The collector container should be washed periodically so as to maintain the easy
viewing translucent characteristic of the collector. Contents may be disposed of in rendering barrel
with permission of rendering company or as solid food waste. To dispose in this manner, empty
grease into plastic bucket lined with trash bag and allow contents to solidify at room temperature or
in cooler before throwing into garbage.
(B) The internal strainer basket should be removed and emptied into a garbage container by shaking
briskly. Wash the inside and outside surfaces of the strainer after emptying.
Weekly Maintenance:
(A) Check the collection trough and the wiper blades for any solids build-up. Wipe off any accumulated
deposits and assure that the wiper blade assembly is re-placed properly.
(B) Press the Skim Start/Stop button (on the bottom-right of the user interface) to ensure that the
motor and skimming wheel are still operating correctly. Press again to stop test. This will not affect
the normal run-time of the unit.
(C) Check the thickness of the grease layer at the top of the unit. There should be no appreciable
amount of grease or oil left in the tank immediately after the daily automatic skimming cycle. If there
is more than a 1/2” (13 mm) thick layer of grease after the skimming cycle, this indicates a need to
increase the skimming time. Increase the digital control settings accordingly until a clean unit appear-
ance is obtained after the automatic skimming cycle. A simple guide is to change to the next higher
setting and run for a period of time until enough grease is being skimmed from the tank.
Quarterly Maintenance:
(A) The internal strainer basket in the unit is designed to remove incidental solids from kitchen drain
ows. Over a period of time, sediment consisting of very ne particles may begin to accumulate on the
bottom of the unit. If this build-up is allowed to continue, it may eventually block the outlet bafe. To
prevent this from occurring, remove the lid and stir the bottom of the unit with a long handled spatula
while water is owing to ush out the sediment. Occasionally drain and clean the unit thoroughly.
Properly used, a wet-vac may be appropriate for this purpose.

Big Dipper®IS System
Digital Control Operation
Timed Skimming Default
Using the “User Interface” ve levels of skimming may be
selected in the “default” mode using the ‘Select Skim Mode’
button. By selecting one of the skim settings – 1, 2, 3, 4, or 5
- the skimming time per day (indicated to the right of the light)
is activated. The LED associated with the selected button is
illuminated continuously as an indicator of the selected skim
cycle and as a “power on” indicator. If the skimming level is
changed during an active skimming cycle, the next active skim
cycle will be at the new setting (The LED associated with the
newly selected level will change immediately). If the skimming
cycle is changed between active skimming cycles the next
skim cycle will be at the new level.
The skim cycle will occur at the same time each day. This is
determined by the time at which power is applied to the unit.
In the case of setting 5, the unit will skim for 60 minutes every
12 hours. To choose a new skim time, disengage power to the
unit and reapply power at the time when skim cycle is desired.
All skim cycles will last no more than 60 minutes at one time.
In the case of setting 5 in default mode or settings in extreme
mode, the electrical assembly will run more than one 60 minute
cycle per day.
Motor Exercising
For all selected skimming levels with system delays greater than
12 hours the skimmer motor will be energized for 5 seconds
every 12 hours. Only the motor will be energized (no heater
operation) at these exercising times.
Skim Start/Stop Button Operation
Any time the start button is depressed operation begins for
the selected skim level. Pressing this button does not effect
the normal timing of the unit. Pressing this button again will
stop the current skim.
Heater Operation
By default, the heater activates 60 minutes prior to a scheduled skim cycle. The heater will operate under thermistor
control with settings of 130°F heater off point, 120°F heater on point for the duration of the preheat and skim cycle..
Extreme Modes
Two (2) additional run-times are accessible which allow the unit to operate more frequently.
• 2+5 - When lights 2 and 5 are both illuminated, the unit will skim for 60 minutes every 6 hours
• 3+5 - When lights 3 and 5 are both illuminated, the unit will skim for 60 minutes every 4 hours
Selecting Default or Extreme skimming
To toggle between the two skimming levels remove power from the Big Dipper® either by unplugging the unit or
lifting the center module to open the interlock switch. Reapply power while holding the Select Skim Mode button
depressed. The number of LEDs illuminated will be the skim level indicator – 1 LED for the default modes and
two for the extreme modes. When toggled from extreme to default mode, level 3 will be initially selected.

Big Dipper®IS System
Troubleshooting
Big Dipper unit overows
(1) Check to see that the outlet pipe is not reduced to a
smaller size, the outlet piping is vented, has as few 90
degree outlet turns as possible, and that no “P” trap is
installed on the outlet. Re-plumb the piping, if neces-
sary. Check outlet piping for clogs. Have a plumber
clean the line, if necessary.
(2) Make sure that the solids strainer is in place and
emptied daily.
(3) Check the bottom of the grease chamber for exces-
sive solids and silt buildup which may be blocking the
outlet bafe. Disconnect the power and use a long
handled spatula or similar instrument to stir the bottom
while water ows through the unit. If necessary, drain
and clean the sediment from the unit. To prevent recur-
rence, schedule this cleaning to be done on a regular
basis (properly used, a wet vac may be appropriate for
cleaning sediment from the bottom of the unit).
(4) Make sure the ow rate to the unit does not exceed
the maximum ow rate, which is shown on the nameplate.
If necessary, have a plumber install an approved ow
control to restrict the inlet ow to the specied level or
install a properly sized Big Dipper for the application.
Excessive water observed in the grease collection
container
(1) Check Digital Control for excessive run time. Unit
will pick up incidental water after all grease is removed.
If necessary, reduce the digital control setting (i.e. 3 to
2) until no water is observed in the grease collection
container.
No grease is collected in the container
(1) Check to be sure the power is on and the correct
setting is chosen. One of the setting buttons should be
illuminated. If none of the setting buttons are illuminated,
the unit is not powered.
(2) Lift the sump cover and clean away any buildup
that may be present on the wiper blades or collection
trough. Make sure the wiper blade(s) are properly in
place on the skimmer wheels. Replace wiper blades
when worn or warped.
(3) Press the Skim Start/Stop Button on the bottom of the
user interface to ensure that the skimming wheel turns.
CAUTION: Keep your hands away from moving parts
to avoid possible injury. If the skimmer motor does not
come on, the motor assembly may need to be replaced.
(4) Check for congealed grease in the unit. If the Big
Dipper’s heating element is not warming the unit, the
heating element may need to be replaced.
(5) Some sites do not generate enough grease to be
captured by the skimming process. Set Control for mini-
mum operation - Setting 1 for Light Skimming Operation.
Objectionable odor
(1) Clean the solids strainer and grease collection
container more frequently.
(2) Make sure grease/oil is being skimmed properly
from the unit.
(3) Check Digital Control for excessive run time. Unit
will pick up incidental water after all grease is removed.
If necessary, reduce the skim setting (i.e. 3 to 2) until
no water is observed in the grease collection container.
(4) If excessive sediment has collected on the bottom
of the unit, clean the unit as described in item 3 in “Big
Dipper unit overows.”
(5) Hydromechanical grease interceptors, grease traps,
automatic recovery units, grease removal devices and
other similar plumbing devices receiving kitchen ows
from sinks, oor drains, woks and other food bearing
sources may generate odors. While the Advanced Odor
Protection features of your Big Dipper are designed to
keep odors from escaping the lid, there may be other
factors inuencing odor evolution and dissemination.
These include room ventilation, kitchen menu, ambient
temperatures, ware washing practices, grease/oil input,
daily input uid volume, sanitizers, installation plumbing
design and product maintenance/upkeep. Odors are
usually prevented by good area ventilation, frequent
uid inputs, good product maintenance practices and
proper product installation. Additional pretreatment
steps not performed by the Big Dipper automatic grease
interceptor, including aeration, chlorination, improved
area ventilation and additional maintenance control,
may be needed at some sites.

Big Dipper®IS System
Plumbing Installation
Locating the Unit
To minimize grease build-up in piping, a Big
Dipper system should be located as close as
possible to the xture it is serving. The sys-
tem should be visible and easily accessible for
maintenance and inspection. The unit must
be in a level position. Be sure to check the
Specication Sheet for your model for the
exact clearances needed for installation. If
the system is located directly on the oor, the
bottom should be sealed to the oor with an
approved silicone type sealant. Make sure
the height above the Internal Strainer access
cover is enough to remove the strainer basket.
Inlet/Outlet Piping
The inlet and outlet piping connections require
exible sleeve pipe couplings. Keep outlet pip-
ing as straight as possible. Use only “sweep”
connections. Do not reduce the pipe sizing
on the outlet piping. Do not install “P” trap on
outlet connection of system. (Note: The system
already has a internal gas trap)
Flow Controls
Big Dipper systems are equipped with an internal
ow control located inside the inlet end of the
system. Verify its location and placement prior
to connecting the inlet piping.
Fill Unit With Water Before Applying
Power
Big Dipper systems, equipped with an electric
heating element, MUST be lled with water
before energizing the power to the system.
Failure to do so may damage the electric heating
element. These elements will NOT be replaced
under Thermaco’s Warranty.
Venting the Outlet
An outlet vent or approved vacuum breaker of
at least 1/2 the diameter of the system’s outlet
connection must be present as close as pos-
sible to the Big Dipper outlet to prevent possible
siphonage problems. Failure to provide a vent
for the system voids Thermaco’s Warranty for
the system.
For High Head Height Applications
Over Six (6) Feet (1.95 m)
Big Dipper systems are equipped with an
internal ow regulator located inside the inlet
end of the system. Verify its location and
placement prior to connecting the inlet pip-
ing. If your code requires a vertical type ow
regulator, an approved control with a ow rat-
ing matching the system’s ow rate should be
used. Note: When a Big Dipper is servicing
multiple xtures, some codes require separate
ow controls for each xture. See following
page for suggested high head height ow
regulation installation.
Do Not Use With Food Grinders, Potato
Peelers or Waste Disposal Units
If the system is connected to a Waste Disposal
Unit, Garbage Grinder or Potato Peeler, Ther-
maco’s Warranty will be void.
Note: Drawing for reference only.
Equipment must be installed in
compliance with all applicable laws,
regulations and codes, including
plumbing codes. Installation should
be performed by a qualied plumber.

Big Dipper®IS System
Plumbing Installation
The following drawings show proposed venting for Big Dipper units in various situations. Check state or local
plumbing code to determine proper installation for your facility.
Sites with Upstream Facility Vents
Sites using facility vents upstream of the Big Dipper unit do not require the use of a vessel vent. In this case, the
open inlet design of the unit works in conjunction with the facility vent and upstream P-trap to facilitate air move-
ment into and out of the interior grease interceptor air space and prevents air bound conditions from occuring.
Sites without Upstream Facility Vents or Other Air Relief
Installations without Upstream Facility Vents or other Air Relief require the use of the vessel vent (also referred to
as a chamber vent) to prevent air bound conditions. Thermaco provides a 1” NPT connection by which this vent
may be connected from the unit to the facility vent.

Big Dipper®IS System
Plumbing Installation
Sometimes space restrictions require the installation of Big Dipper units in basement locations where signicant
head pressure becomes a factor. The Big Dipper®VFCA Vented Flow Control module provides an option for
use with installations where a signicant amount of head pressure is present (greater than 6 ft./1.95 m) or where
applicable regulations require vented ow controls. A Vented Flow Control helps reduce problems associated with
high head pressure and helps slow the drainwater ow down. The VFCA kit contains an appropriate tting and
ow control orice.
VFCA-20 Vented Flow Control for W-200-IS
VFCA-25 Vented Flow Control for W-250-IS
VFCA-35 Vented Flow Control for W-350-IS
VFCA-50 Vented Flow Control for W-500-IS
Installations where head
height is greater than 6 feet
(1.95 m)
NOTE: Drawing for reference only. Equipment must be installed in compliance with all applicable laws,
regulations and codes, including plumbing codes. Installation should be performed by a qualied plumber.

Drawing for reference only. Equipment must be installed in compliance
with all applicable laws, regulations and codes, including electrical codes.
Installation should be performed by a qualied electrician.
Big Dipper Internal Strainer Series Models utilize one Push Button Digital
Time Controller. The Digital Control is located under the hinged lid of the
motor enclosure on top of the lid of Big Dipper (See Digital Control Operation
Instructions). The Big Dipper should only be plugged into a properly
grounded 3-prong 115 VAC or 230 VAC outlet. If possible, the power
supply outlet for the Big Dipper should be connected to an electrical circuit
controlled by a ground fault circuit breaker.
One of the setting buttons should be illuminated to show the unit is
powered. If none of the setting buttons are illuminated, the unit is not
powered.
This Big Dipper unit is shipped from the Factory wired for Preheat Opera-
tion. This means the Heater will come on 1 hour prior to scheduled skim
and heat the water to 125ºF ±5 and maintain this temperature range for
the duration of the skim cycle. Continuous Heater Operation is where the
Heater is active at all times. To switch to alternative heating programming,
please contact a Thermaco representative for further instructions.
Note: The Big Dipper unit will not operate when the lid is removed.

Thermaco Incorporated (“Thermaco”) warrants to the original user that (i) the tank, wrap, lid ends, grease collector, and in-
ternal strainer assembly of the product manufactured by Thermaco and delivered with this warranty (the “Product”) shall be
free from material defects in workmanship and materials during the lifetime of the plumbing system in which such Product is
initially installed, subject to the terms and conditions of this warranty and (ii) the electrical assembly delivered with this war-
ranty shall be free from material defects in workmanship and materials for a period of thirty-six (36) months from the date of
original invoice to the distributor (if sold by an authorized Thermaco distributor) or the date of invoice to the purchaser (if sold
directly by Thermaco). Notwithstanding the foregoing, this warranty shall not cover, and Thermaco shall have no obligation
to repair or replace, any of the following component parts of the Product: gaskets, wiper blades, ip door gaskets, magnets,
and ow control.
Any and all warranty claims must be made in writing to Thermaco at 646 Greensboro Street, Asheboro, NC 27203, promptly
after discovery of the warrantied defect and within the applicable warranty period. Following and subject to Thermaco’s pre-
liminary approval of a warranty claim, the warrantied Product must be delivered, prepaid, to Thermaco, together with proof
of purchase (which must be dated), the Product’s serial number, and a return authorization number issued by Thermaco. If
Thermaco determines upon examination that the Product is defective and that the warranty conditions are satised, Ther-
maco’s sole obligation under this warranty, and the original user’s sole and exclusive remedy, is the repair or replacement,
at Thermaco’s sole discretion, of the defective equipment, component, or parts. Any replacements will be furnished F.O.B.
point of shipment. Thermaco reserves the right to ship the user replacement parts with installation instructions. If Thermaco
determines that the part, component, or the Product is not defective or that any condition of this warranty is not satised, then
Thermaco shall have no obligation to the original user to repair or replace any such part, component, or the Product, and any
return of such part, component, or the Product shall be at the original user’s cost.
This warranty shall not cover any defect in an otherwise covered Product resulting directly or indirectly from (and the occur-
rence of any of the following shall void any otherwise applicable warranty claim): (i) failure to install, operate or maintain the
product in accordance with Thermaco’s instructions and procedures, including, without limitation, use in excess of rated ow,
improper electrical service, use to remove emulsied fats and oils or use that fails to comply with applicable laws, regulations
or codes; (ii) damage in transit, handling or installation; (iii) modications, adjustments, repairs, or alterations made by per-
sons other than Thermaco representatives or certied plumbers or electricians (with respect to the electronic components);
(iv) any change in the original installation or change to the original use of the Product; or (v) other causes not arising out of
defects in workmanship or materials. Thermaco shall not be responsible for damage to products resulting from vault ooding,
sewer line back-up, pumping or lift station failure, ambient water ow or other sources of water damage. This warranty does
not cover equipment or parts not manufactured by Thermaco. Original user’s costs relating to any service, adjustment, re-
moval, repair, packing, or otherwise incurred with respect to the defect prior to submission for warranty are the responsibility
of the original user. No distributor, sales person or other person is authorized to make any warranty statements on behalf of
Thermaco regarding Thermaco products other than as set forth in this warranty. This statement of warranty supersedes and
replaces any quote, brochure, or other statement or document with respect to warranty of the Product.
EXCEPT AS EXPRESSLY SET FORTH ABOVE, THERMACO MAKES NO REPRESENTATIONS, WARRANTIES OR
GUARANTEES, EITHER EXPRESSED OR IMPLIED, INCLUDING, WITHOUT LIMITATION, AS TO MERCHANTABILITY
OR FITNESS FOR A PARTICULAR PURPOSE, WHETHER OR NOT THERMACO HAD KNOWLEDGE OF THE ORIGINAL
USER’S PARTICULAR REQUIREMENTS OR NEEDS, OR WITH RESPECT TO ODOR GENERATION OR OTHER INCI-
DENTALS RELATING TO USE OF THE PRODUCT.
The sole and exclusive remedy with respect to this warranty any other claim relating to defects or any other condition or use
of the Product, however caused, and whether such claim is based upon warranty, contract, tort, strict liability or any other
theory, is LIMITED to the repair or replacement of the effected Product, component, or parts, in each case excluding labor
or any other cost to remove or install the Product, at Thermaco’s sole option, refund of the original purchase price. IN NO
EVENT SHALL THERMACO BE LIABLE, WHETHER IN CONTRACT, WARRANTY, TORT (INCLUDING NEGLIGENCE),
STRICT LIABILITY, INDEMNITY OR ANY OTHER LEGAL THEORY, FOR INCIDENTAL OR CONSEQUENTIAL DAMAGES,
OR FOR ANY OTHER LOSS OR COST OF A SIMILAR TYPE. UNDER NO CIRCUMSTANCES WILL THE AGGREGATE
LIABILITY OF THERMACO FOR ANY CAUSE OF ACTION RELATED TO THE PRODUCTS COVERED HEREBY EXCEED
THE NET PURCHASE PRICE RECEIVED BY THERMACO FOR THE PRODUCTS. Any action or suit by the initial user
against Thermaco relating to the Product must be brought within three (3) years of the date of the invoices referenced above
in cases pertaining to the electrical assembly. This Warranty is made only for the benet of the original user and is void upon
any transfer of ownership.
