Opening the Door
1. Remove the padlock if installed.
2. Grasp the latch handle and pull it toward yourself until the
latch disengages.
3. Keep pulling by the latch handle to open the main door.
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 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, making sure 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.
Pressure Equalization Port
When an upright ultra-low temperature freezer door is
opened, room temperature air rushes into the storage
compartment. When the door is closed, the fixed volume of
air is cooled rapidly. Pressure drops below atmospheric
pressure, resulting in a substantial vacuum. Re-entry into the
cabinet is impossible until internal pressures are returned to
atmospheric pressure. Without a pressure equalization
mechanism, it can take, in extreme cases, several hours
before the door can easily be reopened.
All upright models feature a port that provides vacuum relief
after door openings. The pressure equalization port is located
in the door behind the eye-level panel on the front of the
freezer. Although the port is heated and designed to self-
defrost, excessive frost accumulation on the inner door could
eventually restrict air flow. Therefore, you should periodically
inspect the inner door and brush away any loose frost using a
stiff nylon brush.
Installing the Remote
Alarm Connector
The remote alarm contacts are located on the back of the
freezer above and to the left of the power switch. After
installing the wiring from the remote alarm to the connector,
install the connector to the freezer micro-board.
The pin configuration is shown in Figure 2 below.
Figure 2. Remote Alarm Pin Configuration
For systems that alarm in closed state, connect to pins 5 & 6.
For systems that alarm in open state, connect to pins 6 & 7.
The contacts will trip in the event of a power outage, high
temperature alarm, low temperature alarm or door ajar alarm.
