SO-LOW FDC 4000 Ultra Low Cascade Freezer Instructions

FDC 4000 Ultra Low Cascade Freezer

Product Information: Cascade Freezer

The Cascade Freezer is designed to operate within a specific
range of environmental conditions. It is equipped with an input
circuit protective device that should only be maintained and
serviced by qualified personnel. The protective device uses fuses
or breakers with a rating of 15A or 20A and 250V time delay. The
refrigeration switch is located at the back of the unit, and the
high-pressure control is factory set to cut-out at 298 p.s.i. The
freezer comes with an automatic starting system that activates
whenever there is a power failure.

Product Usage Instructions

Starting Instructions

1. Plug the freezer into a proper outlet with an adequate power
   supply.

2. Ensure that the freezer has at least 6 inches of air space on
   each side for air circulation.

3. Turn the refrigeration switch (located in back of unit) to the
   ON position (if applicable).

4. The compressor(s) will start to operate and pull down to the
   set point on the temperature control.

5. When the freezer reaches the set point, the compressor(s) will
   cycle on and off to maintain the set point desired by the user on
   the temperature control.

Cleaning Procedure

1. Wipe down the exterior of the freezer with a soft cloth and
   spray-type polish.

2. If frost builds up in the chamber, use a bucket and ice-scraper
   to remove it. If excessive ice builds up, defrost the unit (see
   below).

Defrost Procedure

1. Remove any product in the freezer and store it in a backup
   freezer or elsewhere.

2. Unplug the freezer and open the freezer front door/lid.

Automatic Starting System

The refrigeration switch should always be in the ON position to
activate the automatic starting system, which starts up the unit
whenever there is a power failure. A timer will engage after power
is restored to the unit, and the low stage will start to operate.
The automatic starting timer will not operate again until power is
disconnected from the unit or the low stage system cycles off on
high pressure control.

High Pressure Control

The high-pressure control is factory set to shut off the low
stage system in case of high pressure. The low stage system will
automatically restart after a preset time delay.

Warning Symbols

The Cascade Freezer comes with two warning symbols: black with
yellow background and a lightning bolt with an exclamation point.
The first symbol warns of the risk of electrical shock, while the
second symbol advises users to refer to accompanying documents.

Temperature Control

The temperature control is an electronic control with the model
number Partlow No. 1160, FDC 4100, FDC 4000. Unauthorized entry
into this control will void the warranty. To make changes on this
control, use only the up and down keys. Contact the factory for all
other adjustments in settings.

INSTRUCTIONS: CASCADE FREEZER
1.1 RANGE OF ENVIRONMENTAL CONDITIONS FOR WHICH THIS EQUIPMENT IS DESIGNED
1. Indoor use. 2. Altitude up to 2000m. 3. Temperatures 15°C to 32°C ( 60°F TO 85°F ) 4. Recommended humidity range of 30% to 90%. 5. Mains supply fluctuations up to -5% to +10% of the nominal voltage. 6. Transient overvoltages typically present on the mains supply (overvoltage category II). Pollution
degree 1.
CAUTION! THIS FREEZER IS PROVIDED WITH AN INPUT CIRCUIT PROTECTIVE DEVICE WHICH SHALL BE MAINTAINED AND SERVICED BY QUALIFIED PERSONNEL ONLY. FUSES OR BREAKERS USED INSIDE PROTECTIVE DEVICE 15A OR 20A 250V TIME DELAY
WARNING! UPLUG FREEZER BEFORE ANY TECHNICAL SERVICE IS PREFORMED ON THE UNIT!
CAUTION! DO NOT POSITION EQUIPMENT SO IT IS DIFFICULT TO DISCONNECT FROM THE POWER SUPPLY.
1.2 STARTING INSTRUCTIONS
1. Plug the freezer into the proper outlet with an adequate power supply. 2. Confirm the freezer has at least 6″ of air space on each side, for air circulation. 3. Turn the refrigeration switch (located in back of unit) to the ON position (if applicable). 4. The compressor(s) will start to operate and pull down to the set point on the
temperature control. 5. When the freezer reaches the set point, the compressor(s) will cycle on and off to
maintain the set point desired by the user on the temperature control.

1.3 CLEANING PROCEDURE
1. Wipe down the exterior of the freezer with a soft cloth and spray type polish. 2. If frost builds up in the chamber, a bucket and ice-scraper can be used to the ice.
If excessive ice builds up, the unit can be defrosted (see below).
1.4 DEFROST PROCEDURE
1. Remove any product in the freezer and store it in a back-up freezer or elsewhere. 2. Unplug the freezer, and open the freezer front door / lid.
For upright units, use a cloth to protect the control from dripping water. 3. Air out the freezer for at least 12 hours, allowing the unit to reach room temperature. 4. Take a rag and wipe up all the excess water in the unit (melted frost). 5. Plug the unit in and set your temperature to the desired setpoint 6. Once the desired temperature is reached, add product back into the unit. NOTE: It is recommended to slowly re-add your product into the freezer to prevent an extreme load on the compressors, which could shorten freezer life expectancy.
1.5 AUTOMATIC STARTING SYSTEM
The automatic starting system is provided on all freezer systems in case of power failure. If there is an electrical power interruption to the unit and power is not restored immediately, the unit will automatically start up whenever power is returned.
ATTENTION: Always leave the refrigeration switch in ON position, as this will automatically activate the automatic starting system.
Cascade A timer will engage after power is restored to the unit, the low stage will start to operate and the automatic starting timer will not operate again until power is disconnected from the unit or the low stage system cycles off on high pressure control.
CAUTION! COVER SCREEN ON BACK OF FREEZER TO BE REMOVED BY AUTHORIZED PERSONNEL ONLY. FOR CONNECTIONS TO THE EXTERNAL ALARM COVER SCREEN MUST BE REPLACED BEFORE PUTTING FREEZER INTO SERVICE. FAILURE TO REINSTALL COVER COULD RESULT IN HAZARD.

1.6 HIGH PRESSURE CONTROL
The high-pressure control is factory set to shut off the low stage system in case of high pressure. The control is set to cut-out at 298 p.s.i.. The low stage system will automatically restart after a preset time delay.

Manually activate the alarm by moving the toggle switch to the on position once the freezer reaches setpoint.

The alarm will not sound again until the temperature varies 12°C (20°F) from the temperature control set point. Please note that the alarm will sound if there is a power outage to the freezer.
Alarm system should be tested every 30 days.
Non-rechargeable batteries should be changed approximately every two years. Rechargeable batteries should be changed approximately every three years with
lead acid rechargeable 1.2 Ah min, model PS-640F1 or equivalent.
