DANGER
• Do not tilt any unit further than 30° off vertical during uncrating or
installation
• Refrigeration module area contains mechanical, moving parts. Keep
hands and arms clear of this area at all times. If access to this area is
required, power to unit must be disconnected rst.
The equipment must be transported and handled exclusively in upright position, in observance of the instructions
printed on the packing. This precaution is necessary to avoid contamination of the refrigerant circuit with
compressor lube oil with resulting valve and heat exchanger coil failure and problems starting the electric motor or
the risk of gas leak. The manufacturer is not responsible for any problems due to transport executed in conditions
other than those specied herewith. The equipment is secured to a wooden pallet base, wrapped in a plastic lm
and packaged into a three waves carton box. The equipment must be handled using a fork lift truck or a pallet
truck with suitable forks (fork length at least equal to 2/3 length of unit).
1. Remove packing material.
2. Remove accessories from inside the unit.
3. Carefully slide the cabinet off the skid.
4. Use gloves when handling the carton box or the wooden base to
protect the hands from splinters.
5. Position the equipment with the help of a level. Remove the
protective PVC lm from the external surfaces of the unit.
Install shelves (if equipped) and power up
Fig. 1
1. If refrigerator is equipped with shelves, remove bag containing shelf
supports and position them in desired locations on each pilaster
and insert shelves (Fig. 1).
2. Plug refrigerator into a 115 V 60 Hz 15A dedicated outlet.

reinsert probe sensor.
ATTENTION INSTALLER
It is imperative that the probe bottle be lled with
a solution that your facility uses to ensure proper
operation of unit.
2. Adhere supplied probe wire clips (x4, packaged with manual) to
inside wall leading to the probe bottle.
3. Route probe wire into clips and close the clips.

Alarm or Alert Notications
§If an alarm or event condition is detected and an alarm is engaged,
an alert notication will appear in the left center of the screen with an
explanation of the alert condition and a checkbox at the bottom
right of the alert box.
§No further action can be taken on the User Interface until the alert
condition is acknowledged and cleared by touching the checkbox .
§Mute
– Touch the icon to mute audible alarm for 15 minutes.
Door Switch/Alarm
§The equipment utilizes a normally open switch to sense when the door
is open/closed. When the door is closed the switch is in the closed
position which allows for normal cooling system operation. When
the switch is in the OPEN position, the door lights turn ON and the
evaporator fan de-energizes but the compressor continues to run. Once
the door switch returns to the closed position the evaporator fan will
be re-energized. In the event that the door switch remains open for
longer than 60 seconds, the compressor will also de-energize to avoid
an unnecessary ice up of the evaporator coil due to lack of airow. The
door alarm activation time can be changed from 0-600 seconds in the
Advanced Settings Menu under Door Open Alarm Delay.
Power Alarm
§This unit is equipped with a Power Alarm that will sound if the unit
loses power for more than ve minutes. The Power Loss Alarm box will
display every ve minutes, then the screen will sleep. An audible alarm
will sound every 30 seconds during the power failure. An alarm box will
be displayed when power is restored. The event log will record the exact
time and date of the power loss and when the power was restored.
Fig. 11
