grounding terminal or lead of the final appliance.

INSTALLATION
ELECTRICAL CONNECTION
WARNING!!!! DO NOT USE EXTENSION CORDS (VOIDS WARRANTY)
Ground:
The electrical outlet must be provided with an efficient ground, and the voltage and the
frequency of the electrical line matches those indicated on the data plate.
If unsure about the efficiency of the ground, have your electrical circuit
checked by a qualified electrician
• Carefully remove unit from carton or crate. Remove all loose packing materials,
making sure that no small parts or accessories are lost. Inspect the unit for concealed
damage before discarding packing materials.
• It is the responsibility of the installer to comply with all local codes.
• Check unit nameplate for electrical requirements. Make sure that the control knob is
set to the “OFF” position. Connect the electrical power cord and plug to a properly
sized power source of the correct voltage. See wiring diagram on page 12.
• Turn the control knob to the number 5 setting; pilot light will glow and the bottom of
the well will start to warm. As soon as you notice heat turn the thermostat “OFF”.
CAUTION: Bottom of
well will heat rapidly and
may cause severe burns
if touched. Well will turn
a blue-black color due to the high
heat produced when operated dry.
This is normal and will not harm the
well.

START-UP AND OPERATION
DRY OPERATION
• Make sure that the well is empty and clean. Place cover over well. Turn control knob
to the number 10 setting and allow to pre-heat for approximately 30 minutes. After
30 minutes turn knob back to the number 6 or 7 setting until food is placed into well.
NOTICE: Well will turn a blue-black color due to the high heat produced when operated
dry. This is normal and will not harm the well.
• Uncover food well and place pan of prepared food into the well. NEVER place food
directly into food well. Temperature of food being placed into food well must be 160°
Fahrenheit minimum. Turn control knob to desired operating setting. This setting will
vary according to room conditions and type of food being served.
CAUTION: Never add water to a HOT food well that has boiled dry or has
been operated dry. This will cause damage to the well. Allow pan to cool
before adding water.
• Always keep food pans covered when not serving. Change pans of food often to
insure that proper serving temperature is maintained.
THEORY OF OPERATION
Hot food wells are designed to maintain prepared foods at a serving temperature of 140°
to 160° Fahrenheit for one to two hours. They may be operated wet or dry depending on
the type of food being served. NOTICE: When operated dry the stainless steel well will
discolor due to the high heat.
Each individual well is controlled by a positive off adjustable thermostat or infinite control
switch. The knob is marked with an off position and numbered from 1 through 10 with
1 being the lowest setting and 10 being the highest. These numbers do not relate to
a set temperature as this will vary due to the ambient conditions and different types of
operation.

WET OPERATION
• IMPORTANT: Make sure that food wells are at room temperature and that each well
is empty and clean. If the well is equipped with optional drain be sure that drain valve
is closed.
• Fill well with HOT tap water to the water fill mark located at the end of the well.
Approximately 3/4” of water. Cover the well using a tight fitting cover or food pan.
• Turn control knob to the number 10 setting and allow well to pre-heat for approximately
45 minutes.
• Uncover food well and place pan of prepared food into the well. NEVER place food
directly into wells. Temperature of food being placed into the well must be 160°
Fahrenheit minimum. Turn control knob to desired operating setting. This setting will
vary according to room conditions and type of food being served.
• Periodically check the water level in the well. It is very important that food wells not
be allowed to boil dry. When approximately one half of the water has boiled off, hot
tap water should be added to bring water level up to the fill mark.
CAUTION: Never add water to a HOT food well that has boiled dry or has
been operated dry. This will cause damage to the well. Allow pan to cool
before adding water.
• Always keep food pans covered when not serving. Change pans of food often to
insure that proper serving temperature is maintained.
• After the serving period turn control to “OFF” position and allow well to cool before
cleaning.
• Always drain or remove water from well after each meal. If unit is equipped with drain,
place a bucket under the drain pipe and open drain valve. When bucket is full, close
drain valve and empty bucket.
• Clean with a soft cloth or sponge and a mild detergent. Rinse completely with warm
water and then dry.
• A plastic scouring pad and a mild detergent may be used to remove any hardened
food or scale deposits.
NOTICE: Do not use steel wool to clean wells.
• Use a soft cloth or sponge with a mild detergent to clean all exposed surfaces of the
well. Rinse completely with warm water and dry.
