risk of burning yourself if not properly operated. Please read this manual before operating the oven,
avoiding this step could cause you serious damages.
The machine is operated at high current; therefore, the machine should be inspected, maintenance or
repaired only by trained technicians. Always disconnect the unit from main power before removing the
machine side panels.
Performing the any of the following steps will invalidate the manufacturer’s warranty and product
liability.
✓ Installations and repairs that are not carried out by authorized specialist.
✓ Performing any technical changes to the unit that are not approved by the manufacturer.

4 EcoFry - General Information
The EcoFry system is an accessory to the LightFry oven that permits the oven to be operated in
compliance with UL’s specification for ventless cooking. The UL certification allows the oven to be
operated with no external vent hood over it, or a hood that is sized solely for heat extraction. A hood that is
equipped for greasy vapors is not required.
The EcoFry is a catalytic system that converts the greasy vapors coming from cooking food into carbon
dioxide and water vapor. It has an integral heater element to provide the energy for the conversion reaction
that maintains the catalyst at the proper temperature independently of the oven’s set cooking temperature.
EcoFry - Specifications
Metric Imperial
Width 696 mm 27.4 inch
Height 160 mm 6.3 inch
Depth 292 mm 11.5 inch
Weight 17.2 kg 38 pounds
Operating Temp 427 oC 800 oF
The EcoFry unit is delivered in a carton box. Please read the Installation/Operation manual before
attempting to install the unit on the oven or operate it during cooking.

5 Recommended Installation Clearances
Be sure to comply with the clearances recommended in the Lightfry installation manual for areas not
covered in this manual.
Keep a minimum clearance of 12 inches [305 mm] on the left side from any heat source. If possible do not
place any heat sources on the left side of the oven.
Keep a minimum clearance of 2 inches [50 mm] for both the back and right side of the unit.
IMPORTANT! The back side clearance should never be less than 2 inches [50 mm]. Narrower clearances
will restrict natural airflow around the unit and could compromise the electrical cabinet components.
It is recommended to increase the left/right clearance for an easy serviceability when possible. Please note
that should the EcoFry require service it will require a minimum clearance of 12 inches to open the control
panel access door.
Do not install or place any object on top of the unit.
Do not connect a ventilation system directly to the exhaust pipe, allow a minimum distance of 4 inches [100
mm] between the ventilation system and the unit.
IMPORTANT! Be aware of the hot air and steam vapors leaving the exhaust pipe during the cooking
process.

7 EcoFry –Connections to Lightfry Oven
The following steps will guide you through the installation of the EcoFry onto your LightFry oven.
7.1 Mechanical Connections
Before setting the unit on top of the Lightfry oven place the gasketing material around the oven’s exhaust
chimney as seen below:
Remove the indicated screws from the Lighfry oven and retain them for re-installation
Set the EcoFry on top of the Lightfry making sure that the inlet tube of the EcoFry slides over the exhaust
chimney of the oven.
Align the EcoFry so that the holes for the removed screws are visible and then re-install the removed
screws to secure the EcoFry to the oven.
If a gap exists between the top of the oven and the flanged foot on the front of the EcoFry, loosen the
screws on the flange foot and press downward on the flange to close the gap. Re-tighten the screws.

7.2 Power Connections
Power configuration
120-volt, single phase, 3-wire
Total kW
1.5 kW
Maximum Current
12 A
Recommended external fuse
20 A
The model LG1036166-1 is provided with a power cable. Please connect to an appropriate receptacle that
can support the rated amperage. Do not use an extension cord with the LightFry unit to make the power
connection.
7.3 Machine Interlock
The EcoFry has an electrical interlock with the Lightfry unit that signals the oven that the EcoFry is up to
operating temperature and that cooking can begin. There is a cable with the mating connector located on
the bottom of the Lightfry oven that this plugs into. Please see the image below for reference on the location
and how to plug in this interlock.
7.4 EcoFry Exhaust Chimney
The EcoFry unit exhausts are mainly hot air, a very small amount of greasy vapors, and water, as steam,
coming from the moisture in the frozen product. Please be aware of water condensation in the any ventilation
system under which the oven is operated.
If the EcoFry unit is positioned under an existing external air extraction hood there is no need for any other
connection.
The external ventilation extraction system should never be connected
directly to the oven chimney, doing so will alter the cooking process and
IMPORTANT the cooking quality will be compromised.

8 Operation of the EcoFry
The EcoFry unit comes factory programmed for its normal operation with the Lighfry oven. When the
Lightfry oven is powered up the heater in the EcoFry that supplies the energy for the catalytic reaction is
also energized. The oven will not signal its readiness for cooking to begin until it receives a signal from the
EcoFry that the catalyst is at its operating setpoint. Once the unit is ready the oven can be used in any
manner consistent with the Lightfry’s capabilities and operating instructions.
The operating temperature setpoint for the controller is 800oF as seen in the lower number on the display.
The upper number is the current temperature and it will fluctuation between 750oF and ~ 825oF during
normal operation when there is no food in the oven. During cooking the current temperature can read
much higher as the catalyst converts the greasy vapors coming from the food. It is not uncommon to see
temperatures approaching 1,000oF with especially greasy foods. Temperatures this high will not damage
the catalyst as it has a maximum temperature rating of 1,350oF.
The EcoFry has been engineered to work in conjunction with the cleaning process for the oven. No special
precautions are needed provided that those instructions are followed, and only LightFry approved
degreasing cleaners are used in the oven.
The exterior of the EcoFry can be wiped down as needed with any approved cleaner used on the exterior of
the Lighfry oven.
