Specific Precautions
Equipotential Ground Plane
When a high current flows through a conductor, differences in potential appear
between the conductor and nearby metallic surfaces near the appliance. As a
result, sparks may be produced between the appliance and surrounding metal
surfaces. These sparks could cause serious injury, damage, or fire.
BKI provides an Equipotential ground terminal for the connection of a bonding
conductor after the installation of the appliance per lEC60417-1. This terminal is
located on the inside of the Power Entry Supply box near the Earth connection
and is marked with this symbol.

Preheating
You should allow the equipment to preheat at the programmed temperature settings for a minimum of 30
minutes before loading it with product. For initial start up, program the controller for each well heater to a
setting of 7 and each upper heater to a setting of 5.
If equipped with the optional humidity water pan, fill the pan with 6 quarts (5 1/2 liters) of water before
preheating the equipment.
Check Federal and State Health and Sanitation Regulations for internal temperature required for holding
cooked foods for sale. Maintaining these temperatures often tend to allow continued cooking of certain
products. Therefore, smaller amounts of bulk foods should be displayed at non-peak periods and the
warmer refilled as needed.
All meats and vegetables should be preheated to 160°F (70°C). before being placed in the case.
A screen liner can be used in the bottom of the display pans that are used for holding meats. This will
keep meats from sticking to the bottom of the pans.
Temperature Adjustment
After placing the product into the equipment, it may be necessary to adjust the programmed settings in
order to maintain the proper internal temperature for the product on display. The optional built-in product
temperature probe or a portable meat thermometer should be used to read the internal temperature of
each product. The programmed settings should be set to the lowest possible number that will maintain
the proper product temperature.
Operational Guidelines
Keep the optional built-in product temperature probe or a portable meat thermometer on hand. Check the
food temperatures hourly.
Rotate the food products. Foods loaded in first should be served first as much as is practical.
Foods held for long periods of time are more difficult to maintain at proper temperature. Also, freshness
and product quality diminish if foods are held too long. Most areas of the country have sanitation
regulations governing how long foods can be held. Make certain to check with your local authorities.
If equipped with the optional humidity water pan, add 4 quarts (4 liters) of water to the water pan when the
“Add Water” indicator lamp illuminates. If equipment has the remote water fill tube on the back of the
counter top add water through this tube. Otherwise, it will be necessary to remove a food pan above the
water pan to add water.
Unit Shutdown
Remove all food pans holding the food product from the equipment. Depress the OFF pushbutton switch
to turn the power to the heaters and lights off. After the temperature has cooled below 120°F (50°C),
remove any residue from the wells and clean the equipment thoroughly.

Installation
Serious injury, equipment damage or death could result if attempting to install
this unit yourself. Ensure that an authorized BKI service agent installs the unit.
Unpacking and Handling
The company taking delivery of this equipment is responsible for filling all freight claims with the delivering
truck line. Inspect all cartons and crates for damage as soon as they arrive. If damage to cartons or
crates is found, or if a shortage is found, note this on the bill of lading (all copies) prior to signing.
If damage is found when the equipment is opened, immediately call the delivering truck line and follow up
the call with a written report indicating concealed damage to your shipment. Ask for an immediate
inspection of your concealed damage item. Packaging material MUST be retained to show the inspector
from the truck line.
Do not walk on top of deli cases or damage to the cases and serious personal
injury could occur. The cases are not structurally designed to support excessive
external loading such as the weight of a person. Do not place heavy objects on
the deli cases.
Move the deli case as close as possible to its permanent location before moving the case off of the
shipping pallet. Shipping braces are installed on each end of the deli case. Leave these braces in place
while moving and leveling the deli case.
Make certain there are no separately packed accessories before discarding packaging.
During shipment, the lubricant in the gas springs may have settled. This can cause the glass not to
remain open in the raised position. To avoid this, fully raise and lower the glass manually 4 or 5 times.
This unit is designed to be sealed to the floor after it is installed – to conform to
NSF Standard 4. Use Dow Corning RTV # 732 Multi-purpose Sealant.
Floor Model
Leveling
Deli cases must be installed level to insure proper operation and alignment to adjoining equipment. Use a
carpenter’s level as shown in Figure 1. Begin lineup leveling from the highest point of the store floor.
1. Level the case using the leg levelers at the corners of the case (Figure 1).
2. Raise the low end of the case, do not lower the high end.
3. Check for level side-to-side and front-to-back.
4. If you are installing adjoining cases, position the next case in line beside the level case and
proceed to the next step.
5. Level this case in the same manner.
6. When level, bolt the two cases together at the locations shown in Figure 1.
NOTE: None of the end components shown in Figure 2 should be attached to adjoining case
ends
If the cases have been properly leveled, the front panels and counter tops should align with a
small, uniform gap between the front panels of the two cases.
7. Proceed in the same manner until all the cases in the line are level and bolted together.

Figure 1. Floor Models - Leveling
Kick Plate Mounting
A black vinyl-covered kick plate is provided for the front, back and ends of each case.
1. In order to install the Kick Plates it will be necessary to remove the End Trim Panels (see
Figure 2). Remove the retaining nuts located inside the base with a 3/8” wrench. From
outside of the case pull the End Trim Panels away from the case.
2. Slide the front kick plate (the wider of the two) behind the lower finished front panel of the case
(see Figure 2).
3. Make certain that the ends of the kick plate are flush with the ends of the lower finished front
panel and that the kick plate is flush to the floor.
4. Drill 5/32” diameter holes in the case base to match the pre-drilled holes in the kick plate.
5. Attach the kick plate to the case base with the black sheet metal screws provided.
6. Mount the back kick plate to the case in the same manner.
7. Set the End Kick Plates into position on the ends of the case flush with the floor (see Figure 2).
NOTE: There are left and right hand End Kick Plates. The longer end flange faces toward the front of
the case with the black side out. The End Kick Plates fit over the ends of the front and back kick
plates and flush to the floor.
8. Carefully slide the End Trim Panels back into position on the case and push and reinstall the
retaining nuts.
9. This unit is designed to be sealed to the floor after it is installed – to conform to NSF Standard 4.
Use Dow Corning RTV # 732 Multi-purpose Sealant or equivalent silicone sealant to seal the Kick
Plates to the floor around the full perimeter of the case.
