Operation

4.1 Operating Instructions
Upon setting up your equipment, the following steps must be followed to set up the timer and temperature: When this unit is initially switched on, the display will show pre-set factory settings.
4.1.1 Control Panel

Belt Speed “Time”:

• The time is controlled via the top two buttons. The display shows the set time as (MMSS)

• To change the time settings, press and hold the time buttons for a minimum of 2 seconds to adjust in 30-second increments. For
  more precise adjustment press and release to adjust in 5-second increments

• The time in the chamber is from when the product enters the chamber to when it exits the chamber

Elements “Top / Bottom”:

• The top and bottom elements are controlled via the top and bottom buttons. The display will show numbers between 0-99 which indicates a percentage (%) value of the effective power sent to each element. For example: If the top element is set at 99% and the bottom element is set at 50%, there will be approximately double the energy coming from the top element as there is coming from the bottom element
• To change the element settings, press the top or bottom buttons. Each press will move the number by 1

Temperature “Temp”:

• The temp is controlled via the temp buttons. The display will show numbers between 50-350 this is °C
• To change the temp settings, press the temp buttons. The temperature can be set between 50°C-350°C and adjusted in 5°C increments. The display will read the new adjusted temperature in the oven after approximately 10 seconds

Notes :

• If the temp set-point is higher than the element percentages can reach, then the elements will pulse at the top and bottom element % setting and the unit will become a radiant cooker. For most cooking, this will produce less consistent results
• For example, Temp set to 350°C, top element is set to 80%, and the bottom element is set to 50%. There would not be enough energy running to the elements to reach 350°C. This would cause the top element to pulse at exactly 80% and the bottom to pulse at exactly 50%
• It is not recommended to run the unit at 350°C

4.1.2 Operation Adjustments

1. Turn the unit on at the “Power Switch”
2. Adjust the belt speed “Time” to the required setting
3. Set the “Top” element to 90%
4. Set the “Bottom” element to 99%
5. Set the “Temp” to 250°C
6. Place food on the conveyor
7. Adjust as required: increase/decrease the conveyor “Time”, “Top” element and “Bottom” element, and/or “Temp”. Repeat this process until the desired results have been achieved
8. Once satisfied with the results, record the settings for future reference (Refer to our recipe guide for ideas and base settings)
9. Repeat this process for different foods

Notes:

• After 60 seconds the settings will save to the control memory. The unit will now show these settings at startup
• It is recommended to time the belt speed from when the food item starts to enter the oven to when it starts to come out. This is the time the belt takes to pass through the oven

4.1.3 Cross Flow Air/Ventilation

• For best results, there should be no cross-flow air/ventilation (no external fans pointed at the unit). This affects the air curtain at the entrance and exit of the oven chamber, causing temperature instability in the unit.
• Adjust the height of the oven chamber entrance and exit guard to a minimum height above the food product to minimize external airflow entering the unit
• Do not place anything under the unit that may block airflow. E.g.; Gn Pans, Trays, pizza pans, cardboard, etc.

4.1.4 Switching Unit Off

• Do not unplug the unit for at least 30 minutes after the unit is switched off. The fan runs on an internal thermostat which keeps the internals cool and helps to remove excess heat from elements and the oven chamber

Cleaning and Maintenance

5.1 Cleaning
5.1.1 Cleaning Schedule

• Daily cleaning is required for the oven conveyor, crumb tray, and external surfaces. This will help to maintain and prolong the efficiency of your oven
• The unit should be cleaned at the end of each workday

5.1.2 Materials Required

• Stainless Cleaner
• Non-Abrasive Cleaning pad
• Clean Sanitised Cloth
• Paper Towel
• Container of warm water
• Nylon Brush
• Appropriate PPE (Personal Protective Equipment)

5.1.3 General Information

• Cleaning is recommended for health and safety purposes and to prolong the life of the unit
• DO NOT use abrasive pads or cleaners on the stainless steel or any other metal parts of the unit
• DO NOT use industrial chemical cleaners, flammable cleaners, caustic based cleaners or bleaches, and bleaching agents, as many will damage the metals and plastics used on this unit
• DO NOT remove any screws and/or panels for cleaning (unless directed)
• This unit is NOT waterproof, DO NOT hose, DO NOT pour water directly onto the unit, DO NOT immerse in water

5.1.4 Corrosion Protection

• Stainless steel exhibits good resistance to corrosion however, if not properly maintained stainless steel can rust and/or corrode
• Any sign of mild rust and/or corrosion should be thoroughly cleaned with warm soapy water and dried as soon as possible
• NEVER use abrasive pads or cleaners for cleaning
• All metal surfaces should be checked while cleaning for damage, scuffs or scrapes as these can lead to rust and further damage to the product
• Mild rust and/or corrosion can be treated with a commercial cleaning agent that contains citric/oxalic/nitric/phosphoric acid. DO NOT use cleaning agents with chlorides or other harsh chemicals as this can cause corrosion. After treatment, wash with warm (not hot) soapy water and dry thoroughly
• Thoroughly wipe the surfaces dry after cleaning. DO NOT let water pool on the unit. Check crevices and folds for pooling
• When using, ensure all liquids and moisture is cleaned up straight away. Food liquids such as juices from vegetables and fruits should not be left on preparation surfaces
• DO NOT leave items on the stainless steel such as cutting boards, rubber mats, and bottles

5.1.5 Surface Finish

• To protect the polished surface of the stainless steel, it should be dried using a clean dry soft cloth. Light oil can be applied to enhance the stainless steel surface, using a clean cloth apply the oil in the same direction as the grained polished finish
• Some commercial stainless steel cleaners can leave residue or film on the metal; this may trap fine particles of food on the surface, thus deeming the surfaces not food safe

IMPORTANT
Threaded fasteners can loosen in service. Regular inspection and adjustment should be carried out as required
WARNING
This unit is NOT waterproof, do NOT hose. DO NOT pour water directly onto the unit. DO NOT immerse in water
IMPORTANT
Some commercial stainless steel cleaners leave residue or film on the metal that may entrap fine particles of food, deeming the surface not FOOD SAFE
WARNING
Wait until the unit has cooled to a safe temperature before undertaking any cleaning or maintenance. Contact with hot surfaces can cause burns and serious injury
5.1.6 Cleaning Procedure – Conveyor and Crumb Tray

1. Isolate from the power supply
2. Using a good quality nylon brush remove crumbs and small food items from the conveyor. (Switch the unit on to move the conveyor forward, then switch off)
3. Wipe clean using a cloth dampened (not wet) with clean warm water until all soil has been removed. (Switch the unit on to move the conveyor forward, then switch off)
4. Empty and clean the crumb tray. This should be done on a regular basis

5.1.7 Cleaning Procedure – External Surfaces

1. Isolate from the power supply
2. Wearing Personal Protective Equipment (PPE), apply Stainless Cleaner with the Cleaner pad to the external surfaces
3. Scrub any baked-on soil with the cleaner pad in the same direction as grained polish
4. Wipe clean using a cloth dampened with clean warm water until all Stainless Cleaner and soil have been removed
5. Using a clean sanitized cloth, thoroughly wipe the stainless steel and metal parts dry. Do NOT let water pool on the unit. Check crevices and folds

Note: In some areas, particularly seaside environments, stainless steel can be subject to surface discoloration or “tea staining”. This can be removed with an appropriate cleaning agent which contains 10% sodium citrate. Ask your supplier of cleaning chemicals for a suitable brand.
