Health And Sanitation Practices

BKI ovens are manufactured to comply with health regulations and are tested and certified to UL, CUL, and NSF
standards. You must operate the equipment properly using only quality products and use meat thermometers to
insure meats are thoroughly cooked.

Food Handling

• Wash hands thoroughly in warm, soapy water after handling raw poultry or meats.

• Clean and sanitize all utensils and surfaces that have been in contact with raw products.

• Never place cooked meats on the same surfaces used to prepare raw meats, unless the area has been

thoroughly cleaned and sanitized.

Storage Of Raw Meats

• Designate an area or shelf strictly for the storage of all raw meats to be used in the oven.

• Raw product must always be stored at temperatures below 38° F. (3° C.).

• Never store or mix raw foods above cooked foods, as this is a health hazard. The drippings from raw foods

contaminate cooked or processed foods.

• All chicken and chicken parts to be stored overnight must be thoroughly iced down and refrigerated.

Coding Cooked Foods

All products cooked during the day should be sold the same day.

NOTE: It is not the intent of the cooking program to have unsold merchandise at the end of the cooking day. Follow
your company’s procedures for the handling of any leftover product.

Storage Of Prepared Foods

• Cold foods should be kept at or below 38° F. (3° C.).

• Hot foods must be maintained to meet local health codes, usually a minimum 145° F. (63° C.).

CP0058 Color TOUCH Tec Controller Operation

Features

The Color TOUCHTec Controller has the following configurable features that will need to be properly set when
installing a replacement controller. These settings can be entered individually through the configuration screens on
the controller or downloaded from a USB drive.

Temperature Display Units are configurable for Fahrenheit or Celsius.

Operation Language is configurable for English or Spanish.

Audible Alarm Pattern is configurable for Short or Long patterns. This function is helpful to distinguish between

controllers when two controllers are used on the same appliance.

View Recipe is configurable ON or OFF. When ON, a button is displayed on the Cook Recipe screen that will allow

the user to view the settings of the highlighted Recipe.

Power Monitor calculates the energy consumption of the appliance over the elapsed time displayed. This function

can be reset to zero by the user. The energy consumption values for this appliance’s components must be
entered into the controller.

USB Drive can be used to upload or download controller configurations and recipes.

Intuitive Cook Factor is configurable for OFF or values 5-15 in 0.5 increments. If Intuitive Cook is enabled the

Factor determines the amount of cook time compensation.

Control Hysteresis is configurable from 1°F to 10°F by 1°F increments. Hysteresis is the differential between the

temperature the controller turns the heaters off and the temperature it turns the heaters on again.

Extra Time increment value is configurable to 1 minute or 5 minutes.

Cook Temperature Offset is configurable between -50°F and +50°F in 1°F increments. The actual oven cavity

temperature will vary from the programmed temperature by this offset amount.

Door Open Alarm is configurable ON or OFF. When ON, the controller alarms if the oven cavity temperature drops

25°F indicating the door has been left open.

Adjustable Idle Shutdown is configurable for OFF or 10, 20 or 30 minute delay. When enabled, this function will

shut the oven off if it has been preheated and cook is not initiated before the preset time interval has elapsed.

(2) RTD Temperature Probe Inputs configurable to OFF or to monitor oven Cook Temperature or internal Product

Temperature. One input must be configured to monitor oven Cook Temperature. Use of the internal Product
Temperature probe is optional.

(2) Remote Switch Inputs configurable to OFF or to End cycle or add Extra Time when a momentary switch input is

received. Both inputs can be configured OFF.
