Maintenance
-
Turn off the Mains Power Switch
-
Unplug the equipment from the mains power supply outlet.
-
Under good light, carefully inspect the mains power lead and check for any signs of wear, over-extension or
damage. If you believe the lead to be damaged in any way, contact your supplier to arrange for service.
-
Carefully check to ensure all safety warning labels are affixed and in a good readable condition. Refer to the section
in this User Manual titled “Safety Labels & Markings” for a table of factory-fitted warning labels. If any labels are
missing, illegible or otherwise not functional, contact your supplier to obtain new replacement labels before
operating the equipment.
-
Ensure all controls and switches are fitted firmly and are in good condition. If any are found to be loose or in poor
condition, have an authorized service technician repair the unit before operating it.
CAUTION
If any controls or switches are found to be loose or in poor condition, do not operate the equipment. Loose or
damaged electrical controls and connections create a hazardous situation sufficient to cause serious injury or risk to
life. Refer the equipment to an authorized service technician for repair.
Over-Temperature Safety Cutout Test
-
The over-temperature safety cutout should be tested periodically to ensure correct operation. This test should be
conducted once every 2 years of normal operation.
CAUTION
This test must only be carried out by a qualified service technician. The test involves the heating element
becoming very hot and is sufficient to cause serious burns or scalding if contact with the element is made.
Ensure there are no vapours present that may ignite if heated.
-
Turn off the Mains Power Switch
-
Unplug the equipment from the mains power supply outlet and remove it from the water bath.
-
Empty the water bath
-
Fill the water bath with enough cold water to just cover the top coil of the heating element.
-
Re-fit the Professional Sous Vide Circulator to the water bath
Note:
The low level float bulb should drop down to the low-level position, this will prevent the unit from heating and
will cause the alarm to operate once the unit is powered on.
CAUTION
NEVER touch the heating element whilst conducting the Over-Temperature Safety Cutout Test as serious burns and
scalding could result. The test involves the heating element reaching very high temperatures.
ALWAYS wear eye protection during the Over-Temperature Safety Cutout Test.
ALWAYS maintain a safe working distance of 300mm from the Professional Sous Vide Circulator during the Over-
Temperature Safety Cutout Test.
-
Connect power to the Professional Sous Vide Circulator and set the Mains Power Switch to the position indicated
with a vertical line.
