Shelves
All the units come standard with wire shelves. Each unit has
different number of shelves. Refer to Ta ble 3 for more
information.
Maximum shelf capacity is 45 kg (100 lbs) for full shelves.
For safety in shipping, the shelves are packaged and secured
inside the cabinet. Insert the shelf support hangers (included
with the manual inside the unit) into the built-in shelf supports
(located on the inside walls of the cabinet interior) at the
desired locations.
Figure 3. Shelf Arrangement
Figure 4. Shelf Clip
Installation Instructions
1. Determine proper location for shelves clips, the reference
number on the pilaster can serve as a guide to ensure all
clips are properly located.
2. Insert top of the clip into the desired hole of the pilaster
the retaining tab should be facing upwards.
3. Rotate the clip downwards and insert the bottom tab into
the appropriate hole, the clip may be squeezes slightly

4. Install shelves onto clips with the product retention bar
facing upwards, be careful not to is lodge clips during
shelve installation.
5. Prior to loading the shelf, ensure that the shelf is resting
on each of 4 clips and the clips are installed.
Door Operation
The swinging door units are designed to stay open if opened
90 degrees or more. The door spring tension cannot be
adjusted.
The Sliding doors can be opened completely towards left or
right. If the self-closing door does not work properly, make
sure the unit is leveled properly.
Door Seal
Note: Door seal integrity is critical for unit performance. A
loose fitting gasket allows moist air to be drawn into the
cabinet, resulting in quicker frost buildup on the cabinet walls,
longer running time, poor temperature maintenance and
increased operation cost.
Remote Alarm
All units have factory-installed remote alarm contacts that can
be used for remote alarm systems. The maximum distance
between a unit and a remote alarm depends on the wire
gauge used. Refer to Ta b l e 5 below:
The Remote alarm contacts are located on the right side of
the header panel. The three terminals are: COMMON, OPEN
ON FAIL (Normally Closed) and CLOSE ON FAIL (Normally
Open).
WARNING: Do not move this unit while loaded
CAUTION: Improper shelf clip installation may
cause shelf and/or product damage to the unit.
CAUTION: Do not overload the shelves, the unit
is designed to utilize all shelves that are supplied
in an equally spaced manner.
CAUTION: Keep hands and body parts clear of
closing doors.The moving parts create a potential
pinch point.

General Purpose Freezers Installation | 11
To install the remote alarm, make the following connections:
1. Connect the COMMON terminal on the cabinet switch to
the COMMON wire on the alarm.
2. To get an alarm when the switch contacts open, connect
the OPEN ON FAIL terminal on the cabinet to the OPEN
ON FAIL wire on the alarm.

Product Loading and
Unloading Guidelines
When loading your unit, take care to observe the following
guidelines:
• Distribute the load as evenly as possible. Temperature
uniformity depends on air circulation, which could be
impeded if the internal storage components are overfilled,
particularly at the top of the cabinet.
• For critical applications, be sure that the alarm systems
are working and active before you load any product.
• Ensure clearance between the top of the cargo and the
bottom of the internal storage components. Lack of
clearance may affect unit performance or impede
operation of the storage component.
