6. The installation of the unit must conform to the NATIONAL ELECTRIC CODE, ALL LOCAL ELECTRIC CODES AND ORDINANCES, AND ALL THE LOCAL ELECTRICAL COMPANY RULES AND REGULATIONS. Additionally, we recommend a 4" spacing surrounding the unit in order to provide adequate ventilation.

Proper Grounding

USE A GROUNDED OUTLET

DO NOT ADD AN ADAPTOR TO THE PLUG

This machine is provided with a three-pronged grounding plug. The outlet to which this plug is connected must be properly grounded. If the receptacle is not the proper grounding type, contact an electrician. DO NOT, under any circumstances, cut or remove the third ground prong from the power cord or use any adapter plug.

Operation

Preparing the thermal circulator

Food should be prepared first in vacuum-seal bags to ensure no liquid or air can get inside. Please also ensure that the vacuum seal bags are suitable for temperatures up to 203°F (95°C).

  • Press/hold "SET", again until "Time Display Screen" starts flashing, press "Adjustment Buttons" (⬆️ & ⬇️) to adjust to desired time.
  • Press "START/STOP", to exit. The circulator will start and begin to pre-heat water. When the preset temperature is reached, the circulator will signal with three (3) beeps. Press "START/ STOP" to start countdown. After countdown ends, the unit will hold the temperature and signal with a beep every 20 seconds.
• In working mode:
  • The "Temperature Display Screen" will display current water bath temperature. To view the temperature setting, press/hold "SET" to display the last temperature setting.
  • The "Time Display Screen" will display remaining countdown time. To view the time setting, press/hold "SET" again to display the last time setting.
  • Press "START/STOP" to exit and return to working mode.

Start/Stop Button – Working Mode

• Press "START/STOP" continuously two (2) times to stop the circulator working when the unit is heating without countdown.
• Press "START/STOP" one (1) time to stop the circulator working when heating under countdown or in the temperature holding status; the unit will return to ready mode.

Start/Stop Button – Standby/Ready Mode

• After 10 minutes in standby or ready mode with no operation, the circulator will shut down and display "OFF". Press "START/STOP" to return the unit to ready mode.

Operation (continued)

Operating the thermal circulator

1. Open the lid and fill the basin with water. The water level (after the food is put in) should be higher than the "MIN" but lower than the "MAX" markings.
2. Connect the power and turn the power switch to ON (near the plug). The Temperature Display Screen will display as "OFF." Press the "START/STOP" to enter standby mode; the Temperature Display Screen (A) will show the current temperature and the Time Display Screen (B) will show the previous set time.
3. While still in standby mode, press the "SET" button and set the desired temperature and time by using the adjustment buttons.

   NOTE: The flashing screen indicates the one being adjusted.

   NOTE: Default setting is °C. After choosing °C or °F, this will remain in the memory for future use.

4. Place the food into the thermal circulator and close the lid. Press the "START/STOP" to start the unit.

   NOTE: Before cooking, the food must be vacuum packed first. The water level (after the vacuum-packed food is put in) should be higher than the "MIN" but lower than the "MAX" marking on the unit.

? WARNING: Burn Hazard. When in operation, the surface of the Thermal Circulator will be hot. Please take extreme caution. USE CAUTION WHEN TOUCHING THE UNIT.

5. After cooking, the unit will beep. Press "START/STOP" to stop the unit.

   NOTE: The unit will continue to beep after 20 seconds and repeat if there is no action. The water temperature will be kept at the preset temperature for about 30 minutes.

6. CAUTION: HOT STEAM. Slowly lift up the lid, keeping clear of the escaping steam, then lift up the tray and take the food out.
7. After using the Thermal Circulator, turn OFF the power supply. Drain all water after use and clean the unit after each use.

Cooking Chart Guide

This table is only meant to serve as a guideline. Temperatures should be adjusted to your preference of doneness. Cooking time should be adjusted to initial temperature, heat transfer characteristics, and thickness of food being cooked.

NOTE: Times shown in this table are to achieve the absolute specified core temperature. Cook times can be reduced significantly by adding 1° to the water bath temperature. The closer the bath temperature is to the core temperature, the longer the cooking time will be.

Raw or unpasteurized food must be never served to individuals with a weakened immune system, children, older adults and those that may be pregnant, as there is higher risk for serious illness.

NOTE: For most accurate temperature control, be sure to place lid or Sous Vide Insulation Balls (ESV-IB, sold separately) on the vessel when in use.

Care & Maintenance

To maintain the appearance and increase the service life, clean your unit. Tap-water contains minerals. When the water is heated to a certain temperature, there will be scale on the heater or surface of the unit. The SPECTRUM™ Thermal Circulator should be cleaned after every 20 uses or after 100 hours of work time; however, the unit may require more frequent cleaning, depending on the volume of production or due to water in your area.

We suggest draining the water after each use and filling with new water before each use. Reusing old water will cause the mineral in the water to scale on unit components, thus affecting the performance of the unit.

Allow unit to cool to room temperature between water changes and uses. Fill with cool tepid water only.

WARNING: Adding cold water to a hot unit or hot water to a cold unit may cause damage and affect the performance of the unit.

? WARNING: Burn Hazard. When in operation, the surface of the Thermal Circulator will be hot. Please take extreme caution. USE CAUTION WHEN TOUCHING THE UNIT.

⚡ WARNING: Electrical Shock Hazard. Keep water and other liquids from entering the inside of the unit. Liquid inside the unit could cause an electrical shock. Do not spray water or cleaning products. Liquid could contact the electrical components and cause a short circuit or an electrical shock. Do not use unit if power cord is damaged or has been modified.

Cleaning

1. Switch power off, disconnect from the outlet, and let the unit cool down to room temperature before cleaning.
2. The Thermal Circulator should be cleaned regularly. Recommend after 20 uses or after 100 hours, or more per volume of use.
3. Remove the tray and clean separately.
4. Combine a 50/50 mixture of white vinegar and water, and fill container to the "MAX" line.
5. Turn on the unit, set the working temperature to 176°F (80°C), the working time to 3 hours (03:00), and press "START/STOP" to start the unit. After 3 hours, the unit will beep, press "START/STOP" to stop the unit.
6. Check if the unit is clean. Make sure that the filters are cleaned. The filters can be unscrewed to remove for cleaning. If not clean, add vinegar to the unit and run the Thermal Circulator again as stated in the previous step.
7. If the unit is clean, drain the water and vinegar.
8. Rinse the Thermal Circulator with fresh water and dry. Do not submerge unit in water.
9. After drying the unit and accessories, put the accessories back into the Thermal Circulator for storage.
10. Place the Thermal Circulator standing upright after cleaning, do not place it upside down.
