SAVE THESE INSTRUCTIONS
!
IMPORTANT: Your Sous Vide® DISCOVERY is equipped
with an automatic over-temperature safety that will disable
the heater in the event of a heater fault. 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.
WARNING: This Circulator is equipped with a grounded
power cord. Connect the appliance only to earthed
(grounded) power sockets. 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.

COOKING SOUS VIDE SAFELY
Step-by-Step Overview
The basic steps of Sous Vide cooking are very simple and
straightforward. Food can either be served right after it is
cooked or it can be chilled in the vacuum pouch and reheated
later. Just follow the following 5 easy steps.
Detailed Steps With Important Food-Safety
Recommendations
Sous Vide is a very safe cooking method. As with any other
method, Sous Vide requires standard food safety practices.
However, there are two unique issues that are very important
to understand before you start cooking Sous Vide.
• Vacuum-packaging creates an anaerobic or low-oxygen
environment that can encourage the growth of bacteria
such as salmonella and botulism when food is handled
improperly.
• Food cooked at low temperatures for extended periods
of time can cause bacteria to multiply rapidly. The longer
food is in the “danger zone” — temperatures between
40°F and 140°F (4.4°C to 60°C) — the faster bacteria can
multiply and the more dangerous they can become.

1. Set Up Sous Vide DISCOVERY & Water Bath:
• Clamp Sous Vide® DISCOVERY to a stockpot or any other
vessel. Fill with water up to maximum level, indicated on
Sous Vide® DISCOVERY.
• Do not use with more than seven gallons or thirty liters of
water.
• Set Sous Vide® DISCOVERY to the desired temperature.
• Cover bath with lid or plastic wrap for efficient heat-up
time and to avoid evaporation.
2. Trim, Cut & Prepare Ingredients:
• Use only very fresh ingredients from a reputable source.
• The thicker the ingredient, the longer it takes to come to
its cooking temperature.
• Remove or cover pointy bones or anything that could
puncture the plastic pouch.
• Use less seasoning/herbs than you normally would.
• Ensure seasonings and flavors are evenly mixed before
adding to bag. Seasoning and herbs don’t distribute well in
a vacuum-sealed pouch.
• If appropriate for recipe, pre-sear meat and fish to
eliminate surface bacteria.
• If you brine or cure protein before cooking, store food in
the refrigerator.
3. Vacuum-Seal Chilled Food:
• Make sure food is refrigerated at 38°F (3.3°C) or below
until ready to seal.
• Use food-grade plastic bags to seal food.
• To ensure precise and even cooking, arrange pieces of
food in the plastic bag in a single layer.
