Main Power Switch
Turns power On or Off to the entire unit. When placed in the On position, the
shelf heaters are powered and the lights illuminate. When placed in the Off
position, power is removed from the entire unit.
2
Lights Circuit Breaker
Provides circuit protection for the Lights. When placed in the On position
(with the Power Switch in the On position) the illuminate. When placed in
the Off position (with the Power Switch in the On position) power is removed
from lights. If an overload occurs in the light circuit, the Circuit Breaker will
trip causing the actuator to move to the Off position.

SS-OM-002.03 Revised 10/16/18
6
Shelf Temperature
The temperature of the shelves is controlled by thermostats on each shelf and on the base of the unit (see Figure 1). Set
each shelf thermostat on “7” for the initial start up of the unit.
Power Up and Preheating
1. Ensure that the power supply cord is connected to an appropriate power receptacle.
2. Place the POWER ON/OFF switch in the ON position.
3. Place the LIGHTS ON/OFF circuit breaker in the ON position.
4. Allow the unit to preheat for a minimum of 30 minutes before loading it with product.
Check Federal and State Health and Sanitation Regulations for internal temperature required for holding cooked foods for
sale. Maintaining these temperatures often tends to allow continued cooking of certain products. Therefore, smaller
amounts of bulk foods should be displayed at non-peak periods and the unit refilled as needed.
This equipment is not designed to heat-up or cook food. All meat and vegetable products should be preheated to
a minimum of 160F (70C) before being placed in the unit.
Temperature Adjustment
After placing the product onto the shelves, it may be necessary to adjust the individual thermostats in order to maintain
the proper internal temperature for the product on display. A thermometer should be used to read the internal temperature
of each product. The thermostats should be adjusted to the lowest possible setting that will maintain the proper product
temperature.
Operational Guidelines
Only use product packaging suitable for the application.
Keep portable meat thermometers 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.
Unit Shutdown
1. Remove product from the unit.
2. Place the POWER ON/OFF circuit breaker in the OFF position.
3. Place the LIGHTS ON/OFF circuit breaker in the OFF position.
4. After the unit has cooled down, remove any residue from the shelves and clean the unit thoroughly.

Installation
Unpacking and Handling
YOU are 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 place heavy objects on top of the unit or damage could occur. The units
are not structurally designed to support excessive external loading.
Move the unit as close as possible to its permanent location before moving it off of the shipping pallet. Make certain there
are no separately packed accessories before discarding packaging.
Floor Model
Follow the procedure below to level the unit and mount the kick plates. See Error! Reference source not found..
1. Slide kick plates, ends first, between the base frame and outer panels. Secure in raised position with tape. Make
sure that the end kick plates fit behind the front and rear kick plates.
2. Using a carpenter’s level on the lowest shelf, level the unit by adjusting the leg levelers at the corners of the unit.
3. Raise the low end of the unit to level it, do not lower the high end.
4. Check for level side-to-side and front-to-back.
5. Remove the tape holding the kick plates in raised position.
6. Make certain that the kick plates are flush to the floor.
7. Drill 9/64” diameter holes in the base frame to match the pre-drilled holes in the kick plates.
8. Attach the kick plates to the base frame with the #8x1/2” black sheet metal screws provided (SCR355).
9. Seal kick plates to floor using a silicone-type sealant (Dow Corning RTV #732 or equivalent).
