GENERAL INFORMATION

www.elastec.com

CAUTION: Operators must wear gloves and safety glasses while operating unit.

CAPACITY
One MediBurn30 is capable of disposing of 10.5 cubic feet (.030 cubic meters)
of medical waste per load. Since there is a broad range of densities in waste
materials, the actual amount may vary. The waste is reduced to approximately
5% of its original volume. Ash is removed by means of a special rake (supplied
with the unit) and can be emptied directly into appropriate containers.

HOOK-UP
Electrical: In some cases, plugs may have to be installed on the end of the wires
extending from the unit to be compatible with local electrical fittings.
Fuel: There are two options for the supply of diesel to the unit:

Gravity-fed system: A large fuel tank supplies the unit. The bottom of the
tank should be higher than the top of the burner on the secondary chamber.
Mounted tank: Fuel supply is mounted under the unit with a fuel pump and
return line.

CONTROL PANEL OPERATION
The burn times are adjusted using the UP and DOWN arrows on the controller
located on the control panel (see Page 7). When the cycle time is chosen, push
the START button and the MediBurn30 will begin its operating cycle. To change
the cycle time, push the STOP button and change the cycle time. Then restart
the unit.

COMPLETE CYCLE

Unit is switched on, burn chamber door will lock and the 30-second purge
begins (fans only).
7-minute pre-heat (secondary chamber burner fires and begins the pre-heat
process).
Burn cycle begins.
After the firing cycle is complete, blowers in both primary and secondary
chambers blow cool air until the temperature of the unit is 300 degrees
Celsius. If the temperature rises again, blowers will be activated cyclically
until the temperature remains below 300 degrees Celsius.

OPERATING TEMPERATURES
Temperature readouts are visible on the control panel. The unit is designed to
preheat the secondary chamber for 7 minutes before incineration begins in the
primary chamber. Exhaust temperatures are automatically controlled to range
from 1000 degrees Celsius to 1025 degrees Celsius during the burn cycle.
Lower temperatures noted during operation indicate that the materials in the
batch load have been incinerated.

HOW IT WORKS

www.elastec.com

The operating functions of the burners on the MediBurn30 differ from those of
the original MediBurn in that the 30 has two-stage pumps which oscillate based
on temperature, rising and falling during normal burn operation. As the unit
starts its burn cycle and the temperature climbs, the pumps decrease fuel
usage at specified temperatures. This lowers the heat output of the burners.
However, the temperature continues to rise as the under-fired air in the
primary chamber raises the load temperature by increasing the flame of the
burning material. This process increases temperature to a preset point where
the lower burner can shut off, further reducing fuel usage. The upper burner
also oscillates fuel usage as it works to keep the stack temperature at or above
1000 degrees Celsius.

The MediBurn30 incorporates two 24-volt continuous stall motors. One of
these motors is used to operate and maintain the automatic door lock, which is
activated when the START button is pushed. The other 24-volt motor is used to
open and close the under-fired air bypass.

All of these components are controlled by temperature through the system
controller. Should you as the owner or system user have problems with these
components, please refer to the Troubleshooting Guide found on Pages 19-22
or call Elastec at [phone].

BUTTERFLY ASSEMBLY

www.elastec.com

The butterfly assembly, located just above the lower burner, is used to open
and close an air bypass. This motor function should be checked on a regular
basis to ensure that it is working properly. In the top of the motor bracket,
there is a small hole that will allow you to view the shaft coupler set screw.
This set screw will turn and disappear out of sight when the motor is activated.
This process can be easily viewed when the lower chamber temperature is
between 600° Celsius and 1000°
Celsius (1112° Fahrenheit and 1832°
Fahrenheit).

The picture to the right shows the set screw
(arrow) as it appears when the MediBurn30 is in
idle. This set screw will rotate out of view when the
temperature climbs above 600° Celsius (1112°
Fahrenheit), indicating the butterfly valve has
opened, allowing air to bypass into the under-air
system. When the lower chamber temperature
reaches 1000° Celsius (1832° Fahrenheit), the
butterfly valve will close and the set screw will
again be visible. It can also be felt by using your
finger. This bracket rarely gets very hot, due to the
cold air that passes through the tubing and
butterfly valve, making it possible to check this by
hand as well as sight. Should you have to replace
this motor, be sure to orient the set screw so that it
can be viewed through the view hole.

NOTE: It is important to maintain this motor in good working condition, as it is
instrumental in the process of fuel savings.

DOOR LOCK MOTOR ASSEMBLY

www.elastec.com

The door lock motor assembly is located on the right side of the burner
compartment. It is designed to lock the burn chamber door as soon as the
START button is pushed. The door-locking system is designed as a safety
feature and is built in such a way that, if tampered with, the MediBurn30 will not

start. When the burn chamber door is open, the controller scrolls “door open,”

and if the burn chamber door is opened during the burn cycle, the unit will
automatically cycle into cool mode and the unit will have to cool to 300C before
restart can begin.

NOTE: The MediBurn30 must always be cooler than 300° Celsius (572°
Fahrenheit) before trying to load unit.
