How INCINOLET Works
When you push the start button, heater and blower both come on. Heater alternates off and on for an hour. Blower stays
on for an additional 30 to 55 minutes. YOU CAN USE INCINOLET ANY TIME DURING THE INCINERATION
CYCLE. Push start button after each use.
YOU SHOULD INCINERATE WASTE AFTER EACH USE. ACCUMULATED WASTE, PARTICULARLY SOLIDS,
RESULTS IN ODOR AND CAN REDUCE LIFE OF THE HEATER.
If INCINOLET is used primarily in the morning, with little or no use during the day, then reset the timer to 1 1/2 or 2
hours to insure complete incineration. (See page 8.)
Ash is not suitable to use as fertilizer or compost. It should be disposed of in household
trash – just as you would with any other ash waste.
Party Stress For times when you are having a party or house guests, when the INCINOLET may have to serve more
than the stated capacity for a short time, follow these tips:
1. Empty the ashpan before guests arrive.
2. Be sure guests are instructed as to proper use and that a bowl liner is required for each and every use.
3. Push button after each use and check occasionally to be sure itʼs not over filled.
4. You may need to run an extra cycle or two to insure complete burn.
Tips for Success
Use a bowl liner for
each and every use.
Push button to start
after each use.

HOW TO INSTALL INCINOLET
1. Remove all packing materials – including cardboard inside
ashpan panel.
2. Set unit on level floor in desired position:
Allow clearance at rear for wiring and vent-line
connection. Allow at least 2” on left side and plenty of
room on the right side to operate foot pedal.
3. Prepare electrical supply within 4 feet of toilet location.
4. Install mounting plate to floor (RV and WB only).
5. Connect vent-line.
6. Plug INCINOLET into the proper receptacle on a
20-amp circuit. Dedicated circuit recommended.
Preparing Vent-Line
Vent pipe can run horizontally or vertically. Venting materials can be placed within a wall and INCINOLET can be
placed close to a wall at the back. Allow 6 to 8 inches on the right side (facing the toilet) to operate the foot pedal.
Vertical vent-line should terminate with a rain cap. For horizontal venting use a dryer flap or add a PVC elbow turned
downward to prevent back-drafting.

Electrical Preparation
This appliance has a 20-amp plug and is meant to fit only into a 20-amp
receptacle. (Fig. 4) If the outlet you intend to use for the INCINOLET is
not the proper type, then change the receptacle. You must have a circuit
suitable for 20 amps, headed by a 20-amp circuit breaker. Do not
attempt to defeat this safety feature by modifying the plug in any way.
Power cord is 4 feet long.
Extension cords should not be used with this appliance.
START-UP PROCEDURE - Once Incinolet is connected to vent line and
plugged into a 20 amp receptacle on a 20 amp circuit of the appropriate
voltage, itʼs a good idea to run a test cycle using a cup of water poured
into a bowl liner.

For proper operation, vent-line must be as straight as possible with a minimum of elbows. Maximum
length of pipe at the 4” diameter is 20 feet plus 2 elbows. Use larger diameter pipe for longer runs.
Contact Humco if you have questions about special installations.
For best performance, use the shortest possible run and a minimum number of elbows. Do not vent into
an attic or crawl space. Assemble vent pipe pieces securely, gluing or taping all connections. Connect
coupling and pipe to vent collar at the rear of the unit. Put a dryer flap or rain cap at outside of building
to prevent back drafting.

Incinolet Electrical Operation
HUMCO
SANITATION
UNDERSTANDING ELECTRICAL OPERATION
1. Pushing the Start Button closes the Start Switch which engages a timer. Timer begins a new cycle each time
start switch is closed. Timer doesnʼt accumulate time, merely starts over again.
2. Timer is set to 60 minutes at factory. Timer activates temperature controller. Controller output is connected
to the coil of a Relay, which controls the electric current to the heater.
3. Temperature Controller responds to the output from a Thermocouple, which measures Heater temperature.
When the temperature of the lower coil of the heater reaches approximately 1200 degrees F., controller shuts
down the relay, which cuts off the heater. When heater temperature falls to about 1000 degrees F., controller
again activates relay and heater comes on. Heater is off, then on, about twice a minute.
4. Timer also controls exhaust blower. Blower and heater come on and both stay on for 60 minutes together.
After heater cuts off, blower continues on until incinerator area has cooled to about 130 degrees F.
5. Blower Thermostat (ITS) closes when it senses a temperature of 130 degrees F., and stays closed after the
heating cycle is over, until incinerator temperature falls below 130 degrees F., about 30 to 50 minutes later.
Power Consumption
One complete cycle uses about 1 1/2 to 2 kilowatt hours of electricity. Because you can use INCINOLET any time
during the cycle, your “per use” cost is lower.
During a Power Failure
If waste is burning in the INCINOLET when the electric service is interrupted, you may get smoke and odor in the
room. Open a window to ventilate as best you can. When power comes back on, the fan should start automatically,
if needed, and run until unit is cool enough. Heater does not come on until you push the button. You can push foot
pedal to check contents of ashpan then start a cycle if needed.
To Interrupt an Incineration Cycle
In normal use, it is never necessary to stop a cycle to add waste. (See “How to Use”, page 3.) However, on rare
occasions (doing repairs, etc.), you may want to stop a cycle in progress. Turn the circuit breaker off momentarily (or
unplug INCINOLET) to cancel the cycle. Then turn the circuit breaker back on (or plug in INCINOLET) so that the
toilet is ready for use. If unit is hot enough to need it, the blower should come back on automatically to cool it. NOTE:
If blower does not come on, smoke and odor may come directly into room. In this case, you may want to start the cycle
again for a few minutes to finish burning off the waste remaining in the ashpan.
Thermostats
Your INCINOLET is equipped with three thermostats.
1. SAFETY THERMOSTATS (STS) shuts heater off if air temperature inside toilet reaches about 145°F. It is located
on the front surface of the control box at the upper right rear of the unit. To replace, disconnect voltage, remove
top of unit, disconnect lead wires to old thermostat, and replace. (Fig. 9)
2. BLOWER THERMOSTAT (ITS) turns fan off when outside skin of chamber cools to 130°F and will turn fan
on again if temperature increases. It is accessible through access panel opening, just to the left of the heater
terminals. To replace, follow same procedure as for STS above. (Fig. 12)
3 LIMIT THERMOSTAT (TS) turns heater off if skin of chamber reaches a temperature of 325°F. It is located
below the ITS blower thermostat and heater terminals, outside ashpan compartment. To replace, follow same
instructions as for other thermostats. (Fig. 12)
However, on rare

Incinolet Care and Cleaning
HUMCO
SANITATION
CARE AND CLEANING
Keep your INCINOLET clean to prevent odors.
• Empty ashpan when ash is about 1/2 inch deep. EXCESSIVE ASH BUILD-UP CAUSES ODOR,
SHORTENS HEATER LIFE, AND DECREASES EFFICIENCY. If ash is caked and hard to remove,
just soak insert pan for a few minutes in warm water.
• Wipe up urine spills as they happen.
• Every 6 months – clean blower wheel and inside of INCINOLET.
1. Unplug unit and remove top. (See instructions below.)
2. Clean inside with a detergent or a spray cleaner such as Formula 409.
(Do not use pine oil cleaners.)
3. Remove blower wheel and clean. (See page 10.)
4. DO NOT STEAM CLEAN.
5. Stainless steel polish can be used on outside surfaces to keep INCINOLETʼs finish lustrous.
Bowl Liners
BE SURE that the top edges of the liner are below the lid when it closes. Otherwise, paper will burn outside the
chamber and cause momentary smoke and odor. CAUTION: Failure to use bowl liner for each and every use will
always cause odor and urine on the floor.
Bowl liners are made of a special paper coated with polyethylene film. This liner is necessary to catch and contain the
waste, then convey it into the incineration chamber. USE A BOWL LINER FOR EACH AND EVERY USE. Liner
protects the bowl and prevents urine from draining to the floor.
How to Remove Ashpan
Remove ashpan only when pan is cool and toilet is not operating.
Removing the Top (Seat, Lid, Bowl Halves)
Top is held in place with four screws, two per side and a rubber boot which protects the start button. Remove them, and
then lift top up.
To replace top: With incinerator lid closed, hold bowl halves together and lower top into position. Replace four screws
and rubber boot over start button. Tip: If you have trouble holding bowl halves in closed position while placing it back
on toilet, just use a small piece of masking tape to hold them together, then slice through it from the top later.
TIP: If blower becomes
noisy or vibrates, clean
or replace blower wheel.
(See page 10.)
TO REPLACE ASHPAN
Push ashpan firmly into place.
Lift up on ashpan handle and
engage hook of camloc under
ashpan handle.
TO REMOVE ASHPAN
Remove ashpan panel.
Raise camloc handle and
unhook it from ashpan
handle. Pull ashpan out.
Empty ash in garbage.
CAUTION: ASHPAN MUST BE SECURELY
IN PLACE FOR PROPER OPERATION. Push down on camloc handle.
Replace ashpan panel.

Incinolet Troubleshooting
HUMCO
SANITATION
INCOMPLETE INCINERATION
Can be any one of several causes:
1. Start button not pushed after each use.
2. Ashpan too full. Empty more often.
(Empty when ash is 1/2 inch deep.)
3. Too many people using toilet.
4. Burn cycle too short. Add more time
to the timer.
ODOR WITHIN ROOM
Can be any one of several causes:
1. Failure to use bowl liner each and every
time or careless use of liner.
2. Solids not completely incinerated. May
need more time on timer or additional
incineration cycles.
3. Ashpan too full. Empty more often.
(Empty when ash is 1/2 inch deep.)
4. Back-drafting. Use back-draft preventer
on horizontal vent-line or run the vent
vertically with a rain cap at the top.
ODOR OUTSIDE
Causes same as above, plus:
1. Catalyst port perforations are clogged.
Clean chamber wall behind heater coil with
small brush.
2. Catalyst has “set”. Stir with small rod to
loosen. (See catalyst p. 11.)
3. Incinerator lid hanging open, allowing odor
to escape.
RESIDUE BLACK, LIKE CHARCOAL
Ash should be white to gray. Black lumps
means insufficient air is being drawn into
chamber. There may also be soot around ash-
pan lip at front and on inside of ashpan panel.
Remove ashpan and use small brush to clean
perforations in inner incinerator wall back of
heating coils.
BLOWER, HEATER WONʼTSTAY ON
If timer, blower and heater come on when
start button is pushed but turn off as soon as
start button is released, REPLACE TIMER.
BLOWER STOPS AT END
OF HEATING CYCLE
Blower should be on from 30 to 55 minutes
after heater cuts off. Unplug toilet, remove
access panel, inspect for and tighten any
loose wiring. REPLACE BLOWER
THERMOSTAT.
BLOWER DOES NOT OPERATE
Blower must come on immediately when start
button is pushed and should not stop while
heater is on. If not, check blower wheel to be
sure itʼs not binding. Listen to blower motor
for a humming sound (like motor is trying
to start). This would indicate bad motor
bearings. REPLACE BLOWER MOTOR
BLOWER OFF & ON AT CYCLE END
It is normal for blower to stop for 4 or 5
minutes, then start again for a few minutes, a
couple of times at end of cycle. If, however,
blower stops and starts rapidly, blower
(ITS) thermostat is faulty. REPLACE ITS
THERMOSTAT
BOWL HANGS OPEN:
PEDAL WONʼT RETURN
1. Closing mechanism may be out of
adjustment.
2. Foot pedal goes too far down and
locks up. Place block under foot pedal
to prevent excess travel.
EXCESSIVE NOISE, VIBRATION
CLEAN OR REPLACE BLOWER WHEEL.
TIMER & TEMPERATURE CONTROLLER
THE KEY TO TROUBLESHOOTING
Timer limits heating cycle, Controller limits
heater temperature. Timer and temperature
controller are within control box in upper
right corner of housing, accessible with top
removed. Timer has two lights: green and red.
Temperature controller has one red light. A
steady green light on timer indicates unit has
power and is ready for operation. When start
button is pushed, green light begins blinking and
the red light comes on and stays on for a timed
interval, during which time temperature controller
is activated and its red light is on. Controller
red light means that the relay is activated and
supplying power to heater. Controller red light
stays on until timer cuts off after the timed
interval, or heater reaches maximum allowed
temperature and thermocouple signals controller
to open relay. In actual operation, when timer
reaches end of timed
interval, its red light goes off, and blinking
green light turns steady again. During the
timed interval, controller red light will be on
constantly until heater reaches about 1200
degrees F, at which point controller red light goes
off and the relay opens. Controller red light
comes on again after 30 seconds or so, stays on
for about 40 seconds, then goes off again, and so
on until the end of timed interval.
TIMER ADJUSTMENT: (See Fig. 8.)
Timer dial reads 0 to 3 hrs. Timer pointer is
set to 1.0 hrs. If INCINOLET is used primarily
for solids deposits in rapid succession and
incineration is incomplete, move pointer to 2.0
hrs. If used throughout the day, both for urine
and solids, timer would be best set at 1.0 hr. To
adjust timer, remove top of toilet and turn dial
so timer reads new setting. (See p. 7.) Replace
top. DONʼT MAKE ANY ADJUSTMENT
REQUIRING SCREWDRIVER.
TROUBLESHOOTING
BLOWER COMES ON BUT
HEATER DOESNʼTHEAT
Remove top, examine timer and controller as
above. If both timer and controller lights are
on, then heater has failed. To verify, remove
access panel, measure voltage directly across
heater terminals, not from terminal to ground.
If voltage appears, REPLACE HEATER. If
no voltage appears, check circuit further.
TIMER LIGHTS WORK BUT
CONTROLLER RED LIGHT IS NOT ON
Test thermocouple. Unplug toilet, remove
side access panel. Remove wire nuts from
thermocouple leads (#6 & #7). Twist the gray
and purple wires together, then plug unit in
and push start button. If controller red light
comes on, REPLACE THERMOCOUPLE.
CIRCUIT BREAKER OPENS WHEN
START BUTTON IS PUSHED
This indicates heater may be shorted to
ground. Unplug toilet, remove access panel.
Remove orange lead wires to heater terminals.
Again push start button. If blower comes on
and circuit breaker does not open, heater is
shorted. REPLACE HEATER.
Unplug toilet, examine all wiring which might
be grounded by touching housing. REPLACE
OR TAPE ANY BARE WIRES.
NOTHING COMES ON, BUT TIMER
GREEN LIGHT IS ON
Inspect timer lights as you push start button.
Red lights should come on, green light should
begin blinking. If not, CHECK START
SWITCH OR REPLACE TIMER.

MAINTENANCE AND REPAIRS
Clean Blower Wheel
Blower draws fresh air into toilet to provide oxygen for the burn, carries smoke and odor into
the catalyst, then exhausts moist air outside. Clean blower wheel and housing every 90 days,
or any time excessive noise and vibration occur.
1. Remove top of INCINOLET.
2. Disconnect two wires on side of control box to free motor.
3. Loosen (no need to remove) 3 screws holding blower motor plate. (Fig. 10). Twist
and lift motor over screw slots to remove it.
4. Use 1/8” Allen wrench to remove set screw in wheel hub.
5. Clean grease and dirt from wheel with hot soapy water or a degreasing cleaner.
6. Replace wheel if corroded or if vibration indicates it is out of balance.
7. Clean inside of blower housing occasionally.
Replace Heater
Note: For maximum heater life incinerate after each use, and keep
ash level down to no more than 1/2 inch.
To Remove Old Heater:
• Turn off voltage to INCINOLET.
Remove ashpan. Remove access
panel. Remove top. Hold
incinerator open either by wedging
down the foot pedal or blocking
flushing mechanism in open
position.
• Remove thermocouple but do not
disconnect. (Fig. 12)
• Disconnect wiring to heater
terminals. Remove cover plate and
insulation around heater terminals.
(Fig. 11-1)
To Install New Heater:
• Reverse above procedure. Locate
heater in brackets, making sure
brackets are seated in slots in the
incinerator wall. (Fig. 11-2)
IMPORTANT: Locate heater at
lowest position in heater bracket.
Coils must not touch each other.
• Replace insulation and cover over
heater terminals. (Fig. 11-1)
• On new heater coil, remove nut and
only1ofthe2newwashers. Slip
heater wireʼs connector over the
terminal, then the 2nd new washer
and a nut. It is best to reuse the
original lock nut, but the new nut
can be used if needed. Always
use the new washers, one on either
side of the heater wire connector.
•CAREFULLY tighten nut, using
two (2) end wrenches to prevent
twisting the heater stud terminals,
which would break the moisture
seal at end of heater (Fig. 11-1).
• Replace thermocouple. Push knurled
cylinder to compress spring. Turn to
engage stud, then release. Spring must
be compressed to insure that tip of
thermocouple contacts outer surface of
heater.(Seep.11.)
• Replace access panel, ashpan, top.
Close circuit breaker.
• Start cycle to test heater and total
operation.
• Push up on heater coils to clear
heater brackets. (Fig. 11-2)
• Remove heater through ashpan
opening. (Fig. 11-3)
Note: Brackets may be wedged
tightly in slots in wall. It is okay
to remove brackets, but not
absolutely necessary.
