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 remove 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.
Single Stage
After power restoration, the single stage will start to operate and begin to pull down to
setpoint temperature.
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.

VERSION 6.1.17
The nCompass display is split into two sections; the upper icon bar and bottom main display area.
The basic functions and settings for the upper Icon Bar are listed below:
The menu icon will open the main menu for navigating to the different control and
monitoring screens. Menu items will dynamically appear providing available options
based on the system area the user is in, i.e., security, data logging, setup, etc.
The information (help) icon will display text based help associated with the current
screen. Help is available in three languages, English, Spanish and French based on
the user selection in the offline setup of section of nCompass.
The home icon will return the user to the main view from anywhere in the nCompass
application. The main view is set by the OEM in the nCompass configuration and can
be the single or dual loop, trend, alarm, alarm history, event or digital IO view.
The alarm icon will appear and flash when a new system alarm occurs. Pressing the
alarm icon will take the user directly to the alarm monitor screen in order to view and
/or reset the active alarm condition.
The speaker icon will open the volume control menu, which controls the audible level
of temperature and condition alarms. The volume setting of “100”is the factory default
setting. Moving the volume dial to the “0”will disable the audible alarm.
IMPORTANT: Do not use any sharp or metal objects on the touch screen as they may damage the
surface. Also be sure that hands and fingers are free from oils or chemicals which may
mar the surface of the touch screen
Attention: Loading time between menu screens or parameter selection screens may vary.
Some menu screens may require several seconds to load before the information is displayed.
Pushing the display several times while a menu or parameter is loading may result in menus
being opened, or parameters being changed unintentionally.

FDC nCompass
VERSION 6.1.17
In the case of power failure, the nCompass temperature control switches from AC power to a backup
battery located inside the electrical panel of the freezer. This battery is the 6 volt rechargeable type, and
is designed to last approximately 24-48 hours during power failure. It is recommended to test the battery
on a regular basis and replace the battery when needed (approximately 3-5 years).
ATTENTION: The battery backup system only powers the control during power failure.
It does not power the refrigeration system, and the freezer will not run during power failure.
When unplugging the freezer to put it into storage, the power failure alarm will sound. To disable this
power failure alarm, you will need to disconnect the battery; which is located in the electrical panel.
To do this, complete the following procedure:
1. Locate the electrical panel on the side of the freezer.
2. Remove the screws with a Phillips screwdriver, and remove the panel.
3. Locate the battery (which is clearly marked) in the lower right hand corner.
4. Disconnect one lead from the battery by removing the connector on the battery.
5. When returning the unit to service, complete steps 1-4, but reconnect the unplugged battery in
step 4. Then plug the freezer into the outlet to restore power.
It is recommended to keep the freezer plugged in and running when possible. Leaving the unit
unplugged for long periods of time may shorten the life expectancy of the freezer.

The battery backup system on the freezer only powers the control during power failure. It does
not power any additional network systems which may be required for your internet to operate.
It is recommended to have your local network router, and modem, connected to a battery
backup, so the freezer’s internet connection will continue to operate during power failure.
