IV. OPERATION | V. CARE AND MAINTENANCE: |
IV. c - DEFROST CONTROL (CONT'D): compressor restarts. The next defrost cycle will start in about 5 hours 40 minutes. On models ULT27, ULT48 and ULT60, the defrost time control is located on the right side of the evaporator housing, behind the temperature control adjustment screw. On earlier models ULT48 and ULT60, the defrost time control was accessed through a small round opening on the outside rear of the unit.
IV. d - REFRIGERATING PRODUCT:
A Thermometer (figure 13) is provided inside all UHT, ULT & UPT models. Allow the cabinet to reach normal operating temperature before loading.

UHT, ULT & UPT Series will satisfactorily refrigerate an assorted load of food items. Allow space between articles to permit free air circulation. Do not overload at any one time with warm food products and expect immediate results. A certain amount of time is required to remove heat from items before operating temperatures can be attained. The system is designed for storage of refrigerated or frozen product.
Opening the door will increase the temperature in the cabinet and will require a certain amount of time to recover. Also, after peak service periods or after warm product is loaded, the refrigerator will require a certain amount of time for the temperature to return to the normal operating range.
IV. e - PANS & DIVIDER BARS:
Sandwich Prep models are provided with 1/6 size plastic pans and metal divider bars. When 18 one- sixth size pans are ordered, four standard and one wide pan divider / supports are provided to achieve appropriate pan separation. When 24
V. a - CLEANING THE EXTERIOR:
Exterior stainless steel should be cleaned with warm water, mild soap and a soft cloth. Apply with a damp- ened cloth and wipe in the direction of the metal grain.
Avoid the use of strong detergents and gritty, abra- sive cleaners as they may tend to mar and scratch the surface. Do NOT use cleansers containing chlorine, this may promote corrosion of the stainless steel.
Care should also be taken to avoid splashing the unit with water, containing chlorinated cleansers, when mopping the floor around the unit.
For stubborn odor spills, use baking soda and water (mixed to a 1 TBSP baking soda to 1 pint water ratio).
V. b - CLEANING THE INTERIOR:
For cleaning the interior, the use of baking soda as described in section “V. a” is recommended. Use on breaker strips as well as door gaskets. All interior fit- tings are removable without tools to facilitate clean- ing.
V. c - CLEANING THE CONDENSER COIL:
Check the condenser coil periodically. The operating environment will affect the required frequency of cleaning. Air must be able to freely circulate through the condenser. This surface must be kept free of dirt and grease for proper system operation. Remove the lower rear panel on the rear of the equipment cabinet. Carefully clean dirt and lint from the condenser coil using a vacuum cleaner or soft brush; do not use a wire brush. Replace the lower rear panel. Reconnect electrical power supply.
V. d - CONDENSATE REMOVAL SYSTEM CARE:
The evaporator coil, condensate loop and condensate pan, when needed, can all be flushed with fresh water by a qualified service technician. This should be part of any routine maintenance program and can prolong the life of the equipment.
Condensate removal is provided by evaporation at the lower rear portion of the equipment cabinet and does not need a drain. Periodic cleaning of the condensate removal box may be needed. To access the condensate removal box, remove the lower panel at the rear of the equipment cabinet. Clean the condensate removal box by wiping it out with a clean damp cloth, using care with the condensate loop inside. Replace the lower rear panel. Reconnect electrical power supply.
WARNING: DISCONNECT ELECTRICAL POWER SUPPLY BEFORE CLEANING ANY PARTS OF THE UNIT.
