GENERAL INSTALLATION
FABRICATING
1.Consult installation and connection data and installation diagrams on following pages for regular cone or regular
sink attachment dishtable cutout sizes.
2.For cone attachment, position cone so water swirl inlet fitting is nearest to operator .
3.Weld the total circumference of cone or sink attachment to prevent leakage.
4.Smooth grind and polish to match and blend weld seams.
NOTE: DO NOT PLACE CONTROL MOUNTING BRACKETS IN DIRECT WATER SPLASH AREAS.
PLUMBING
1.Consult installation and connection data and installation diagrams on following pages for mounting, hookups and
pipe sizes.
2.“H” Series is mounted by suspending from dishtable.
3.“A”, “B” and “C” Series use a floor leg support system with a neoprene connecting sleeve and two (2) stainless
steel clamps. Supplied sleeve (8” length) should be cut to required length for connection of disposer to dishtable.
4.Slide in, or position, disposer to connect to waste line, avoiding as many bends, elbows and tees as possible.
5.Flexible drain connection should be installed as follows:
A. Slip coupling over disposer outlet, then onto drain pipe.
B. Using a 5⁄16” nut driver, tighten to a torque of 60 in-lbs.
6.Perform power-rotor reaming of waste line whether connection is made to a new or old waste line. New lines
often contain foreign items left in the lines accidentally during construction.
7.Blow new water feed lines out before connections are made. Dirt, solder, or other foreign matter can lodge itself
in the flow controls, solenoid valve and vacuum breaker , causing malfunction.
8.Install solenoid valve. Check that inlet and outlet ports are in proper direction.
9.Check that disposer and dishtable opening are in line, level and true. This is visible when neoprene sleeve is
not kinked or partially collapsed. If level and in line adjustment is required, turn feet on bottom of legs.
10.Secure disposer to floor using the holes provided in the feet.
ELECTRICAL

TYPICAL INSTALLATION
START-UP AND RUN CHECK
1. Check that vinyl silver trap scrapping ring is fully seated.
2. Check that all connections are secure.
3. Check that disposer is secured to floor.
4. Open terminal wiring box on motor; pull out and separate motor leads to permit ampere reading on each leg.
Leave all connections and insulation in place.
5. Clamp ammeter over input feed lead.
6. Turn on disposer.
8. Check for leaks, water flow, excessive noise or vibration, and regulate water flow if required.
7. Take ampere readings on each leg and verify against factory-checked motor test results.
NOTE: Before checking rotation reversal, be sure disposer is empty. Wear safety glasses or goggles. BE SURE POWER
SWITCH IS OFF SHOULD ADJUSTMENTS ON DISPOSER BE NECESSARY. NEVER REACH INTO DISPOSER WHEN DIS-
POSER IS RUNNING.
9. If disposer is connected to a reversing control, whether automatic or manual, check reversing.
10. If disposer is connected to a manual reversing drum switch or contactor, START motor in forward position and note rotation
through top opening as motor coasts to a stop. RESTART motor in reverse position. Verify that disposer restarted in opposite
direction.
11. If disposer is connected to a control center with automatic reversing (Model RAC1/ RAC2), verify if disposer reverses.
NOTE: Motor must be stopped or 30 seconds must have elapsed before pushing START; otherwise, motor will not reverse. This
is a safety cycle feature. Should START button be pressed prior to elapsed time, motor will run in same direction. Direction Test:
A.) Press Start- Disposer Run. B.) Press Stop (note coast down direction. C.) Wait 30 sec. after motor stops. D.) Press startDisposer should run is opposite direction.
12. If disposer is wired with a (RAC1/ RAC2), There are 3 trim-pots on the Control Module inside the controller that adjust operation. (To enable or disable clean out cycles) For more information about this Eco-Mizer: Electricity and Water Saver please
see the Instructions For Adjustable Timer With Auto Shut Down spec sheet in the control box. This timer is used to control the
shut down sequence of industrial garbage disposal units. When either the Stop input is activated or the Auto Shut Down timer
times out, the two stage shut down sequence begins. The first stage is Clean Out, where both the motor and water flow continue
for up to 2 minutes. The second stage is Positive Flush, where the motor is stopped, but the water flow is continued, also for up
to 2 minutes. The disposal may be restarted at any time, but if the motor has been off for more than 30 seconds, its direction will
be reversed.
13. In all shutdown phases, be sure water is being shut off by the closing of the solenoid valve.
14. Reinsert all wiring, close all covers and shut all doors that were open during run check.
Red Goat Disposers 10/12Page 9
OPERATION
1.Check that disposer is empty and clean from previous use.
2.Check that vinyl silver trap scrapping ring is in place and properly seated over throat opening in cone or sink.
3.Turn disposer ON. Note that water is flowing into top cone or into sink via the water swirl fitting.
WARNING: Never feed waste by hand past vinyl silver trap ring or reach inside running disposer .
NOTE: Do not feed metal, wood, cloth, rubber, corn husks, plastics, plastic sheets of bags, styrofoam, or other foreign
matter. A periodic clean out of such material from the disposer is advisable.
4.Proceed with dish cleanup, feeding waste gradually. DO NOT pack waste into disposer waste chamber .
5.After each use, if disposer is wired with manual controls, allow disposer to run (motor and water) for at least 2
minutes. This clean-out cycle will empty the disposer and flush the waste line, preventing potential drain
stoppage.
6.Should motor stop during use cycle, SHUT OFF POWER IMMEDIA TELY, via ON-OFF switch. If disposer is
connected to Model RAC2 Control Center , shut OFF power at black emergency disconnect handle; on manual
switches, turn branch circuit disconnect to OFF.
A. Remove vinyl silver saver scrapping ring and check waste chamber through top opening and remove foreign
objects that may have caused stoppage.
B. Check to see if rotor turns freely.
C. If rotor turns freely, replace vinyl silver saver scrapping ring and turn disposer ON.
If disposer fails to start and run, an obstruction may still be binding the rotor .
A. Turn disposer OFF. Using a wooden bar or wooden handle, pry and push against the impact bars on the
rotor to break it free; then remove object.
B. Turn disposer ON and if motor fails to start, the thermal protector, either in the motor (“H” and “A” Series) or
in the controls, may have tripped.
C. Push reset button on thermal protector.
If disposer still fails to start, check for blown fuses or tripped circuit breakers in the branch circuit (especially on
three-phase installations) to be sure that all power legs are feeding motor .
TROUBLESHOOTING
DISPOSER DOES NOT START WHEN NEW
Manual reset button of thermal protector is tripped. On “H” and “A” Series, reset button is on motor; on “B” and “C”
Series, reset button is in control box.
Fuses or circuit breaker on branch circuit feed line have tripped.
Electrical connectionf on motor, in panel or feed lines not tight.
Headers have not been installed in starter, if starter is used in circuit.
DISPOSER DOES NOT START AFTER STANDING UNUSED FOR A PERIOD OF TIME
Clean out cycle too short. When disposer is stopped too early, the remaining water slowly drains out carrying the
shattered waste particles into the very close clearance opening between sizing ring and rotor, where it hardens and
solidifies, acting as a binding agent between the two parts. The motor at start-up is unable to overcome the dried
blockage (usually on low horsepower disposers).
DISPOSER STALLS WHEN IN OPERATION
Large quantities of foreign material (rags, wood pieces, rubber bands, strings, pieces from floor mops, cellophane
and polyethylene) which will not disintegrate, cause the motor to overheat and the thermal protector to trip.
Not enough water volume flow (GPM) causing thermal protector to trip.
Thermal protectors (heaters) sized too small, causing nuisance tripping.

MAINTENANCE
Waste disposer troubles usually involve plumbing. A preventative maintenance program is advisable to keep waste line
stoppage and disposer repair at a mininum. Any sewer problem occurring shortly after your disposer has begun
operation cannot be caused by the new machine. It will be the result of connecting to either an inadequate waste line,
or to one that has not been properly cleared before use. On the other hand, if waste line clogging occurs after the
disposer has been running trouble-free for a year or more, this indicates probable need for servicing.
The slurry leaving a new disposer contains no discernible solids, so there is nothing to clog the waste line. In regular
use, however, wearing of the working parts is to be expected. As the gradual wear occurs, the solid particles passing
through the wider gaps in the shatter mechanism will grow increasingly larger, until waste line stoppage may result.
See Figures.
MONTHLY WEAR CHECK
NOTE: The following should be performed every two weeks if waste is of a highly abrasive consistency .
1.Shut OFF branch circuit power, or emergency disconnect on control panel when disposer has completed its
clean out cycle.
2.Loosen stainless steel clamps on neoprene connector sleeve.
3.Twist neoprene sleeve loose and remove.
4.On “B” and “C” Series, loosen Quick-Release body clamps and lift of f aluminum lid.
5.Remove any foreign objects (rubber bands, metal, wood, plastics, etc.) from waste chamber .
6.Check free movement of rotor.
7.The two points of probable wear are the leading edges of the impact bars and the spacing between the outer
edges of the rotor and the inner diameter of the sizing ring teeth (Figure 1, Page 13). When one end of each
impact bar is worn rounded, as shown in Figure 2, Page 13, they need to be reversed (if disposer is wired to an
automatic reversing control).
A. Loosen four hex socket head cap Allen screws to release the bars. Should it be necessary, use liquid wrench
or a mixture of oil and kerosene to help loosen the screws.

MAINTENANCE
B. Reverse bars and reinstall Allen screws.
C.
When the edges of the reversed impact bars become rounded (Figure 3), the bars must be replaced.
See below and Page 14.
8.The second point of wear is the clearance between the outer edge of the rotor and the inner diameter of the
sizing ring teeth (Figure 3).
If the space between the rotor and sizing ring has grown to 3⁄32”, (.094) and the impact bars are worn (rounded)
as shown in Figure 3, replacement of total rotor and sizing ring is advisable. See below and Page 14.
NOTE: If 3⁄32” space between rotor sna sizing ring is left to continue to increase, waste line stoppage may result as
increasingly large whole sections of waste will pass through sizing ring without breaking up.

POINTS OF WEAR
When these impact bars are reversed,
presenting new working sides, this
disposer will function well even though
this space may have grown to 3⁄32”.
At this stage of wear, no new parts
are needed.
With uniform wear on the rotor and the
teeth, spacing between has increased,
but the new faces of the reversed bars
restore efficiency.

These bars have had their double life. FIG. 3
With both sides well worn, it is evident that this disposer was
properly cared for, getting maximum length of service from all parts.
Red Goat Disposers 10/12
At this stage of double wear on bars,
this space may be 3⁄32” (.094). Check
with feeler gauge or U.S. Std. #13 gauge
wire.
At this stage, bars only may be
renewed–provided spacing between
rotor and teeth has not grown to 3⁄32”
and if waste line appears capable of
handling the slurry output.

below machined surface on rotor.
13.Reinsert key. Series “B” and “C” use two keys. BE SURE the keys make metal to metal contact on all surfaces
in the rotor and motor shaft keyways and that the key is the full length of the keyway. Short keys will shear at
peak loads. Rotate rotor slightly to be sure there is no radial play between the rotor and motor shaft.
14.Insert cover gasket, plate and bolt to lock down rotor .
15.Torque cover bolt to 34 ft-lbs.
16.Install one new gasket on base.
17.Place sizing ring over gasket on base and thread in new centering studs.
