Case Not Lining Up

Water Is On The Floor

See Installation Section for instructions on properly aligning case (alongside other cases) and adjusting levelers.

Caution! Water on flooring can cause much damage! Until cause is

determined (and repaired), following these procedures:

• Use wet-dry vacuum (or mop & bucket) to remove standing water.

• Use ‘catch pans’ for water to drain into. Swap out regularly until

case has completely drained.

Note: See Drain, Hose and Bracket Placement Illustrations sheet in this

manual for views of different evaporator systems used in display cases.

Check that the drain trap is free of debris.

Check that the drain hose is correctly positioned over evaporator pan (or

CPC® CONTROLLER - OVERVIEW / ESC3 CONTROLLER OPERATION

Controller Overview: The CPC® ESC3 series is an

electronic refrigeration controller that provides control of compressor, fan and defrost management. The ESC3 provides control of a compressor (or solenoid) valve in response to temperature variations.

Temperature Control: Temperature control in the ESC3 is

accomplished by comparing the temperature reading of case temperature probe against temperature set point. Compressor output is used to control temperature. If temperature is above temperature set point (LI) + the hysteresis set point (rd), compressor output is turned on. If the temperature is below temperature set point (L1) - the hysteresis set point (rd), compressor output is turned off.

Compressor Control: Several setpoints are available to allow operation of compressor output to be

tailored to match individual needs.

Min ON/Off Times and Minimum Cycle Time: Minimum ON/OFF compressor times can be

specified, as well as a minimum time delay between compressor cycles. These parameters help prevent short cycling.

Compressor Power On Delay: Compressor power on delay setpoint (c0) allows user to specify a

delay after power-up of the controller. The compressor output will not come on regardless of the temperature reading until this amount of time has expired.

Compressor Safety Cycle: The Compressor Safety Cycle setpoint (c4) specifies a cycle time that

the compressor is to be cycled if the temperature sensor used for control fails. If this setpoint is 0, the compressor will be off. If this setpoint is 100, the compressor will be on. Any value between 1 and 99 will result in the compressor being on for that period of time. At the end of this time, the compressor will be shut off for approximately 15 minutes.

Interface: The ESC3 features a 3 digit LED displaying supply air temperature. Supply air tempera-

ture will always be cooler than actual case temperature. For actual case temperature, see internal case thermometer. The temperature can be displayed in either

C or 0F.

Alarm Key - The Alarm key illuminates when the controller has detected an alarm condition.

This key is also used to reset an alarm condition and to enter the setup mode (allowing the set points to be changed).

Compressor Key - The Compressor key illuminates when compressor output is on. When

ESC3 is in setup mode, this key is used to select a set point to be modified and to change set point value.

Defrost Key - The Defrost key illuminates when the ESC3 is in defrost mode. Press the de-

frost key for 5 seconds to go into manual defrost mode. The key is also used in setup mode to select a setpoint to be modified and to change the value of the set point.

Alarm Operation - The ESC3 has several alarm functions. In addition to alarms based on air tem-

peratures, it will alarm if a probe failure is detected.

Indications on the Display: If the “defrost” or “compressor” key blinks, the corresponding function is

delayed by a timing routine or is inhibited.

Code Chart: See next page.
