This document describes the VESTA TT-300/TT-300A Electric Conveyor Toaster, an appliance designed for commercial use in hotels, supermarkets, restaurants, and fast-food establishments.
Function Description
The VESTA Electric Conveyor Toaster is designed for baking bread and buns. It features a conveyor system that moves bread through a heating zone, allowing for continuous toasting. The device offers adjustable heating modes and conveyor speeds to achieve desired toast color and accommodate different bread types and moisture content. Cooked bread can be collected from either the front or back of the appliance, providing operational flexibility.
Important Technical Specifications
The manual provides specifications for three models: TT-300, TT-300A, and TT-300A (stack version).
All models operate on 120V voltage and a 50/60Hz frequency.
- TT-300: Power of 1750W, dimensions (L x B x H) of 418mm x 368mm x 387mm, and a speed of 300 pieces per hour.
- TT-300A: Power of 1750W, dimensions (L x B x H) of 418mm x 368mm x 387mm, and a speed of 300 pieces per hour.
- TT-300A (stack version): Power of 1750W x 2, dimensions (L x B x H) of 418mm x 368mm x 775mm, and a speed of 300 pieces per hour x 2. This indicates two units stacked, effectively doubling the capacity.
The device requires a mounting space of at least 1500mm x 850mm x 530mm (L x W x H).
Usage Features
- Adjustable Conveyor Speed (Colour Control): The bread color is controlled by regulating the conveyor speed. A knob allows users to select the desired speed; a faster speed results in lighter toast, while a slower speed yields darker toast.
- Multiple Heating Modes (Level Governor): The level governor offers several heating options:
- Top heating
- Top & bottom heating (strong)
- Bottom heating
- Top & bottom heating (weak)
There are also specific settings for "BREAD" (top and bottom heating elements active) and "BUNS" (only top heating element active). A "STBY" position is available for warming.
- Lead-in Rack: Equipped with a lead-in rack for smooth loading of bread onto the conveyor.
- Crumb Tray: A crumb tray is located below the rack to collect bread crumbs, facilitating easy cleaning.
- Dual Bread Lead-out Options: Users can choose to collect cooked bread from either the front (bottom food tray) or the back (back food tray) of the appliance, providing flexibility in kitchen layout and workflow. The back slide board can be pressed down to direct bread to the back tray and pulled up to reset for front collection.
- Preheating: The appliance requires preheating for approximately 10-12 minutes before baking to reach the optimal chamber temperature of around 284°C.
- Stackable Design (TT-300A stack version): The TT-300A model can be stacked using a stacking kit, allowing for increased capacity in a smaller footprint.
Maintenance Features
- Easy Crumb Removal: The crumb tray can be easily pulled out for cleaning after the appliance has cooled down.
- Cleaning Precautions: Before cleaning, the appliance must be unplugged and the power supply cut off. Water jets should not be aimed directly at the appliance, especially the electrical box, to prevent electric shock. The device should not be immersed in water.
- Professional Installation and Maintenance: Installation and maintenance should only be performed by professional technicians. Any adjustments or repairs require contacting the manufacturer or qualified personnel.
- Grounding: The device must be reliably grounded according to local regulations, with a copper wire no less than 1.5mm² connected to the equipotential terminals at the lower back of the box.
- Disconnecting Switch: The fixed wiring arrangement should include an all-pole disconnecting switch with a contact opening of at least 3mm on its poles. Installation of a grounding leakage protection switch or relay (with a leakage peak of 10mA) is advisable.
- Power Cord Replacement: If the power cord is damaged, it must be replaced by the manufacturer, its maintenance department, or similar professional personnel using dedicated or specialized components.
- Routine Inspection: Regular checks include verifying power supply, control panel functionality, absence of strange odors or sounds, and vibration.
- Troubleshooting Guide: The manual includes a common fault section with symptoms, causes (e.g., defective thermostat, burnt-out heating elements, damaged indicator, abnormal power supply, burnt fuse), and corresponding solutions (e.g., replace thermostat, replace element, replace indicator, check power supply, replace fuse). Users are advised to stop using the device and inform professional technicians for repair if any failure occurs.
