SO-LOW FDC 4100 Ultra Low Chest Freezer Instructions

STARTING INSTRUCTIONS

Plug the freezer into the proper outlet with an adequate power supply.
Confirm the freezer has at least 6” of air space on each side, for air circulation.
The compressor will start to operate and pull down to the set point on the temperature control.
When the freezer reaches the set point, the compressor will cycle on and off to maintain the set point desired by the user on the temperature control.

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.

CLEANING PROCEDURE

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

DEFROST PROCEDURE

Remove any product in the freezer and store it in a back-up freezer or elsewhere.
Unplug the freezer, and open the freezer front door / lid.
For upright units, use a cloth to protect the control from dripping water.
Air out the freezer for at least 12 hours, allowing the unit to reach room temperature.
Take a rag and wipe up all the excess water in the unit (melted frost).
Plug the unit in and set your temperature to the desired setpoint
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.

TEMPERATURE CONTROL

The temperature control is manually adjustable to the desired temperature in 1° C increments within the limits of the control range.

WARNING
Unauthorized entry into this control will void warranty

PARTLOW NO. 1160, FDC 4100, FDC 4000 ELECTRONIC CONTRO

NOTE: USE ONLY THE “UP” AND “DOWN” KEYS WHEN MAKING CHANGES ON THIS CONTROL. WARRANTY WILL BE VOID IF USED IN ANY OTHER WAY. CONTACT FACTORY FOR ALL OTHER ADJUSTMENTS IN SETTINGS.

TEMPERATURE SET POINT: The control has two displays, the upper display is the actual chamber temperature and the lower display is the temperature set point. The temperature set point has been preset at the factory.

CHANGING TEMPERATURE SET POINT: The temperature set point can be changed by simply pressing the “up” arrow to raise or the “down” arrow to lower the temperature set point

ALARM SYSTEM

MODEL	OPERATION INSTRUCTIONS
FDC 4000	Alarm will automatically activate when the freezer reaches

set point or 8 hours after the unit has been first plugged in.
FDC 4100| Manually activate the alarm by moving the toggle switch to the on position once the freezer reaches setpoint.
PARTLOW 1160| 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.

ALARM BATTERY TESTING

If applicable, the alarm switch has a test position that can be used anytime to see if the battery is charged or if the buzzer is working properly.

OPTIONAL EQUIPMENT – DRY CONTACT ALARM RELAY Located on the back of the freezer is a terminal strip marked ALARM RELAY CONTACTS. Rating of this connection:

ALARM RELAY CONTACTS CONNECTION RATING

RED – NORMALLY CLOSED
WHITE – COMMON
BLUE – NORMALLY OPEN

CAUTION! IF IT IS NECESSARY TO REMOVE METAL COVER SCREEN ON BACK OF FREEZER TO MAKE CONNECTIONS TO ALARM RELAY, COVER MUST BE REPLACED BEFORE FREEZER IS PUT INTO OPERATION

Table A.1 Error Codes and Corrective Actions

Error Code	Display Symbol	Error Description	Corrective Action
******** 4		Illegal setup values been used: Before COOL

is used for OUT2, DIRT ( cooling action ) has alreadybeen used for OUT1,or PID mode is not used for OUT1 ( that is PB = 0, and / or TI = 0 )| Check and correct setup values of OUT2, PB, TI and OUT1. IF OUT2is required for cooling control, the control should use PID mode ( PB= 0, TI=0) and OUT1 shoulduse reverse mode (heating action), otherwise, don’t use OUT2 for cooling control.
10| | Communication error: bad function code| Correct the communication software to meet the protocol requirements.
11| | Communication error: register address out of range| Don’t issue an over- range register address to the slave.
14| | Communication error: attempt to write a read-only data or a protected data| Don’t write a read-only data or a protected data to the slave.
15| | Communication error: write a value which is out of range to a register| Don’t write an over-range data to the slave register.
26| ****| Fail to perform auto-tuning function| 1. The PID values obtained after auto-tuning procedure are out of range. Retry auto-tuning.2. Don’t change set point value during auto-tuning procedure.3. Use manual tuning instead of auto-tuning.4. Don’t set a zero value for PB.5. Don’t set a zero value for TI.6. Touch RESET key
29| | EEPROM can’t be written correctly| Return to factory for repair.
30| | Cold junction compensation for thermocouple malfunction| Return to factory for repair.
39| | Input sensor break, or input current below 1 mA if 4-20 mA is selected, or input voltage below 0.25V if1- 5V is selected| Replace input sensor.
40| | A to D converter or related component(s) malfunction| Return to factory for repair.
