When using electrical appliances, basic safety precautions should
always be followed, including the following:
1. Do not operate this Circulator with a damaged power cord or plug,
or if it has been dropped, damaged, or malfunctions. Return the
Circulator to PolyScience for examination and/or repair.
2. Do not let power cord touch hot surfaces or hang over the edge of
table or counter.
3. Unplug from electrical outlet when not in use.
4. To avoid the possibility of personal injury, always unplug the
Circulator from the electrical outlet before cleaning the unit.
5. To protect against the risk of electrical shock, submerse only the
heater/pump portion of this Circulator in liquid. The maximum
submersion depth is indicated on the housing of the unit. If the
Circulator or power cord falls into liquid, unplug the power cord from
the electrical outlet immediately. DO NOT REACH INTO THE LIQUID.
6. Do not use an extension cord with this Circulator.

Notice.
This Circulator is equipped with a grounded power cord which must be
plugged into a properly grounded power outlet. Do not use the appliance
if the grounding prong on the plug is missing or damaged or with a
grounding adapter. Contact a qualified electrician if the plug does not fit
into the electrical outlet you intend on using.

IMPORTANT: Your Sous Vide Professional is equipped
with an automatic over-temperature safety that will
disable the heater in the event of a heater fault or if it is run
with insufficient cooking liquid for too long a time period.
If this safety cannot be reset, the unit must be sent back
to PolyScience.
!
IMPORTANT: COUNTERTOP PROTECTION
Some countertop materials may not be able to withstand
the prolonged exposure to heat required for sous vide
cooking. To safeguard against damage to your countertop,
PolyScience recommends that you always place your
cooking vessel on a trivet or other insulating material before
you begin heating the cooking liquid.

Food Safety Warning.
The food safety issues in cooking sous vide are different from more
conventional forms of cooking. Do not start to cook before you fully
understand the specified food handling practices to prevent, eliminate,
or reduce the food biological, chemical, and physical hazards to a safe
level.
Familiarize yourself with and follow the instructions provided at www.

Set-Up.
Your Sous Vide Professional Thermal Circulator is easy to set up:
1. Place the flow adjustment slides on the Circulator to the
desired positions. These slide controls allow you to easily adjust
the force with which the cooking fluid circulates. For maximum
circulation (recommended), open the front slide control and close
the rear slide control.
2. Attach the Circulator to the cooking vessel (user-supplied). The
mounting clamp on the back of the unit will mount it securely to
both flat and rounded vessel walls. Allow a minimum of 0.5 inch /
1.3 cm clearance between the bottom of the Circulator housing and
the bottom of the cooking vessel.
3. Add the tap water to the cooking vessel. The depth of the liquid
in the cooking vessel should be kept somewhere between the
“Maximum” and “Minimum” liquid level lines embossed on the
heater/pump housing.
WARNING: To avoid the potential for burns and/or electrical
shock, do not change the position of the flow adjusters
while your Circulator is immersed in liquid. For safety, turn
power to the unit OFF, unplug from the electrical outlet,
remove Circulator from reservoir, and allow the housing to
cool to room temperature before making adjustments.
IMPORTANT: The water level in
the cooking vessel will rise as
food is added. Be sure to allow
for this displacement when
placing liquid in the vessel.

Use a soft brush to remove any lodged particles. If necessary, soak in
clean water to soften before brushing. DO NOT use hard utensils or
abrasive pads to remove trapped food debris.
