Page 8: The Use Of Casters
CASES MOVE ON CASTERS FOR EASIER INSTALLATION ORIGIN 2 cases are manufactured and shipped to stores with casters installed on the base frame to make the job of moving cases easier for everyone involved with the manufacturing, shipping and instal- lation process. -
Page 9: Installation
The O5DMA is shipped with most of the exterior panels and trim already installed. The only exterior parts that need to be installed when the case arrives are the kick- plate and the end kickplates. If the cases are equipped with contour front panels the upper kickplate retainer is also shipped loose with the case. -
Page 10: Refrigeration Piping
REFRIGERATION PIPING The expansion valve and other controls are located on the left-hand side of the case and are accessible without lifting the fan plenum. The controls cluster may be reached by lifting only the left hand deck pan minimiz- ing the need to unload product. -
Page 11: Component Definitions
COMPONENT DEFINITIONS Access Valve - Access port on the evaporator that allows service personnel to check system pres- sure. Accumulator - A device installed on the suction line that is used to boil off small amounts of liquid refrigerant so liquid does not reach the compressor. Compressor - An electrically driven piston pump that pumps vapor refrigerant from a low pressure level to a higher pressure level. -
Page 12: Plumbing
PLUMBING All of the plumbing components are attached to the case at the factory so there is no assembly required. The case drain is located front and center of the cases for convenient access and is specially molded out of ABS material. The “P” trap, furnished with the case, is molded of PVC. -

- Page 17 CONTROL SETTINGS ESC3 Controls Operation Temperature Control Temperature control in the ESC3 is accomplished by com- paring the temperature reading of the case temperature probe against the temperature setpoint. The compressor out- put is used to control the temperature. If the temperature is above the temperature setpoint (L1) + the hysteresis setpoint (rd), the compressor output is turned on (subject to the con- ditions described in the compressor operation sec-tion).
- Page 18 CONTROL SETTINGS ESC3 Controls Alarm Operation Indications on the Display If the defrost, or compressor key blinks, it means that the corresponding function is delayed by a timing routine or inhibited. Other two-character messages may appear on the screen to indicate changes of state or alarm condi- tions.

Page 24: Case Cleaning
CASE CLEANING Case is designed to facilitate cleaning. There is a wide radius formed on the front and back of the inside bottom that helps accelerate liquid flow and eliminates difficult-to- clean sharp corners. All surfaces pitch to a deep-drawn drain trough that angles toward the front and center of case where the waste outlet is located for easy access. - Page 25 FANS The evaporator fans are equipped with either 9 watt fan motors, 1550 RPM’s, or 12 watt fan motors, 1650 RPM’s. Both motors have a counter clockwise rotation when viewed from the shaft end. The fan blades are 8” in diameter and the blades are pitched to 37 degrees on each model as shown on the chart below.
