PREFACE SECTION 1
IN-SINK-ERATOR manufactures commercial food waste disposers from
1/2 horsepower through 10 horsepower.
The basic assembling or disassembling of all SS Series models is
identical. However, electrical connections do vary depending on the
disposer specifications, power supply and electrical controls. You will
find disposers with single-voltage, dual-voltage and tri-voltage motors
and for either a single or three phase power supply. Electrical
connections for various electrical controls that may be used with the
disposer are shown in this manual. Standard electrical connections are
also included.
The method of mounting the disposer is uniform throughout models as
is the mounting bolt circle diameter.
Basic models covered in this manual:
Above serial number 70,000:
SS-50
SS-75
SS-100
SS-125
SS-150
SS-200
Above serial number 130,000:
SS-300
SS-500
SS-750
SS-1000
This manual may be used for general referral for disassembly on SS
series models prior to models shown above.
Models shown here are Basic Model Numbers, (i.e. SS-150) which
includes several motor variances. The specification decal on the motor
trim cover will reveal the Complete Model Number, (i.e. SS-150-24
denoting the motor is 115/208/230 Volt, Single Phase).
Whenever new replacement parts are used/ordered, you must know the
Complete Model Number, serial number, motor voltage and phase
found on the specifications decal. You Must use correct parts sheet for
specific model you are servicing.

SECTION 2 PRIOR TO REPAIRS
Prior to diagnosing a problem, one must give consideration to the
following items so that proper service adjustments are accomplished
intelligently and without delay or "call-backs".
• Obtaining complete information on the phone will help the service
technician before he arrives at the job site.
• Apparent electrical problems may actually be caused by a
mechanical problem (I.E. worn bearings can cause a unit to hum
and not run).
• Commercial disposers may be controlled by various types of starting
controls and electrical accessories.
• Has someone else been on the job "attempting" repairs?
• A "cheater" test cord can be used to by-pass all electrical starting
and/or electrical controls to run the disposer "direct".
• Do the electrical specifications of the disposer match the electrical
power supply? Are the motor lead connections proper for the power
supply as well as the starting controls?
• What is the age of the disposer? Any previous problems? Is it sized
properly?
• Always make certain you have and use the correct wiring diagram(s)
for the job and use the correct parts sheets.
• The only place (repeat-only place) to obtain the correct model
number is from the disposer specifications plate.
• You may have to adjust the water supply to the correct recommended G.P.M.
• If the problem is electrical, are there electrical problems with other
kitchen equipment?
• If you contact the factory for help, all of the above must have been
considered.

INSTALLATION-REMOVAL-OPERATION SECTION 5
IMPORTANT
These installation instructions are for the benefit of the installing
contractor. The IN-SINK-ERATOR Company or any of its
Authorized Service Centers do not make original installations. For
technical information not covered In the following instructions,
contact the Factory.
These electrical and plumbing instructions were written under the assumption
that the installer is competent and experienced in these areas. If the installer is
not experienced in these areas, we recommend that competent Professional
assistance be sought. Improper installa tions resulting in damage to the disposer
or accessories are not covered by the warranty.
All installations are to be in accordance with local plumbing and electrical
codes.
GENERAL PLUMBING INSTRUCTIONS
1. Before installing the new IN-SINK-ERATOR Disposer, properly clean
out the waste lines to the connecting main sewer.
2. Recessed thread fittings (sanitary fittings) should be used throughout,
and all pipe ends should be carefully reamed and free of burrs.
3. Use as few elbows and tees as possible. Be sure that the fittings used
are of the long sweep type.
4. All horizontal drain lines should have a minimum of 1/4" fall per foot.
A 2" pipe (minimum) is recommended for models with the following
horsepower: 1/2, 3/4, 1, 1-1/4, 1- 1/2 and 2. A 3" pipe (minimum) is
recommended for models of these horsepowers: 3, 5, 7-1/2 and 10.
5. Keep horizontal runs as short as possible to reduce the possibility of
plumbing stoppages.
6. Do not connect into a grease trap, drum trap or interceptor.
7. IN-SINK-ERATOR Disposers from 1/2 through 1-1/4 H.P. are equipped
with a drain outlet designed for a slip joint connection to a standard 11/2" "P" trap (not furnished). Connect the trap with a branch waste line
running directly into a 4" stack. IN-SINK-ERATOR Disposers from 11/2 to 2 H.P. have an outlet flange with 2" internal pipe threads (N.PT.)
assembled to the disposer. IN-SINK-ERATOR Disposers from 3
through 10 H.P. have an outlet flange with 3" internal pipe threads
(N.P.T.) assembled to the disposer. Connect "P" traps as close as
possible to the outlet flange.

SECTION 5
OPERATING INSTRUCTIONS
1. PUSH THE START BUTTON on the switch to put the disposer in
operation (see Figure 5-16). Before you start feeding food waste into
the disposer, make sure that a steady stream of water is flowing into
the disposer.
2.
Don't feed garbage into disposer until unit is started and water
running.
3. FEED THE GARBAGE into the disposer in a steady, continuous flow.
4. Don't overload disposer with excess amounts of garbage and water.
The unit will consume food waste faster when you feed it steadily.
