Page 4: Introduction
Introduction 1. General This manual provides installation, operation and maintenance instructions for Freze-Cel Models 5549 (steel plates) and 6049 (aluminum plates). These freezers use hydraulics to raise and lower double-contact freezer plates to permit loading and unloading of product. Refrigerant is fed to the freezer plates though a Phillips injector nozzle, which provides a 2 to 1 liquid re-circulation rate. -
Page 5: Description
Description 1. Purpose of the Equipment The Freze-Cel is ideal in situations where freezing time is critical in preserving a product’s quality. In addition, since the product is held firmly between plates during freezing, package flatness and uniformity are assured. 2. -

D. Refrigeration Cycle Refrigerants offered in the Freze -Cel are R -502, R-404A and R - 507. The refrigeration cycle is as follows: (Refer to Dole Drawing 7511-B100). The high-pressure liquid stored in the condenser flows through the filter/dryer, through the sub-cooling shell and tube heat exchanger, to the bottom of the injector distributor. -
Page 8: Electrical System
F. Electrical System The freezer is factory wired. The installer must provide the proper power source to the system’s electrical control panel. In some areas voltage can vary to such an extent that damage to a compressor can result if built in compressor protection devices fail to react fast enough. -

Page 15: Operating Instructions
Operating Instructions 1. General Once water and electrical power have been connected, certain procedures should be followed to assure safe and efficient performance of the freezer. 2. Check of Electrical Power DO NOT OPERATE THE COMPRESSOR UNTIL POWER HAS BEEN ON FOR AT LEAST FOUR HOURS. -
Page 16: Product Loading
the “COMPRESSOR” switch has been in the “OFF” position for more than a day, observe the following: CAUTION: Do not operate the compressor until electrical power has been supplied to the freezer for a period of at least FOUR hours. The crankcase heater requires power for at least four hours to evaporate any liquid refrigerant that may have migrated since the unit had been shut down. -
Page 17: Crankcase Oil Level
DO NOT add refrigerant unless sight glass indicates in undercharge condition after running the compressor for at least two hours. 8. Crankcase Oil Level After the compressor has been in operation f o r at least two hours check the compressor crankcase oil level. The oil level in the crankcase oil sight glass should stabilize at the center of the sight glass, with compressor operating. -
Page 18: Maintenance
Maintenance General This section provides instructions on preventive maintenance, refrigerant charging, liquid pumpdown and compressor oil charging procedures. 1. General Maintenance Once a day during the normal operating cycle, with the COMPRESSOR RUNNING, the refrigerant level in the surge drum sight glass should be checked. -
Page 19: Crankcase Oil Charging Procedure
a. If the freezer has just completed a freezing cycle, turn off the compressor by positioning the “COMPRESSOR” switch to “OFF”. Let the unit sit overnight with the doors open and the MAIN POWER SWITCH on. This will insure that the crankcase heater remains energized to prevent refrigerant migration to the crankcase. -
