Super Insulated Cabinet
Construction
In all models, the cabinet walls have a vacuum insulation core
encapsulated by a sealed film laminate.
Door Operation
Upright freezer models are equipped with an advanced
assembly specifically designed for ultra-low temperature
freezers.
Features include:
• One-hand operation
• A front-accessible lock.
• Hasps for a standard padlock to provide additional
security. Length of the shackle must be between 3/4 inch
(1.9 cm) and 11/2 inch (3.8 cm).
• Durable construction for reliable operation and safe
product storage.
• Door ramp alignment feature.
• Optional controlled access to the freezer with Proximity
Access cards.
Opening the Door
For freezers with the Proximity Access Card option:
1. Remove the padlock if installed.
2. To unlock the door, pass the card in front of the freezer
below the LCD display.
3. Grasp the latch handle and pull it toward yourself until the
latch disengages from the cabinet strike.
4. Keep pulling by the latch handle to open the main door.
For freezers without the Access Card option:
1. Remove the padlock if installed.
2. Grasp the latch handle and pull it toward yourself until the
latch disengages from the cabinet strike.
3. Keep pulling by the latch handle to open the main door.
Opening the Door During a Power
Outage
In case of power outage and a unit that has the Proximity
Access Card option, you may use a 9 V battery to activate the
system. To access the 9 V terminal, remove the USB cover
and locate the battery terminals.
Once the terminals are exposed, open the door by holding the
9 V battery against the terminals and pass a valid proximity
card below the display area. Once the door is open, remove
the 9 V battery.
Note: The terminals are polarized therefore orient the 9 V
battery properly.
Closing the Door
Note: The latch does not self-engage automatically when you
close the door. You must rotate the latch into the open
position first.
1. Grasp the latch handle (preferably with your left hand)
and pull it toward yourself, rotating the latch into the open
position.
2. Move the freezer door into the closed position and gently
push the handle away from you, ensuring that the latch
engages fully with the cabinet strike.
3. Keep applying gentle pressure to the latch handle until
the latch is securely in closed position.
4. Insert the key and rotate counterclockwise to lock.
5. Replace the padlock as required.
CAUTION: Never drill holes in or near the
cabinet walls. Drilling could damage the
insulation and make the unit inoperable.
CAUTION: When moving the freezer, always
grasp cabinet surfaces; never pull the freezer
by the latch handle.
