SECTION 1 - INSTALLATION
Inspection and Storage
Store cabinets, chassis, and risers the same way they
were shipped. Ensure the storage area is dry and pro-
tected from the environment. Keep the units in their
upright position. If the risers are stored at the job site,
ensure the pipe ends are capped to prevent foreign ob-
ject debris and contamination.
In areas where construction is not complete (including
dry wall, plaster, paint, and where any emission of dust
particulates or fumes from outgassing are present), all
precautions must be taken to protect the cabinet, open-
ings, and chassis from contamination or physical damage.
Upon delivery, perform the following inspections:
1. Inspect the unit for shipment damage. Notify the
Transportation Company of any damage and note
the damage on the shipping receipt.
Rough handling may dislocate and dam-
age internal components.
2. Inspect the riser projections at each end of the
cabinet for misalignment or end damage that
would prevent making an acceptable connection.
3. Inspect the thermostats and other accessories that
have been shipped separately for quantity and
transit damage.
Store the refrigeration chassis in the normal upright
orientation to maintain oil in the compressor sump.
Preparations for Installing the Unit
Before installing the unit, perform the following prep-
arations:
• Verify the model number on the unit nameplate
with the ordering and shipping information to en-
sure the correct unit has been shipped.
• Carefully inspect each unit before delivery to the
installation site. All cabinets may not be equipped
with the same size riser or the same air supply
grille arrangement. In most cases, each cabinet is
individually tagged for a specific location in the
building.
• Keep the cabinet sealed with the shipping materi-
als until all plastering, painting, and construction
work is complete.
• Remove the inner service panel and manually
check the blower wheel for free rotation.
• Match the refrigeration chassis to the proper cabi-
nets by referring to the cabinet and chassis name-
plate and label information.
• Remove the chassis refrigeration access panel
(top cover) and inspect the unit. Ensure that the
refrigerant tubing is free from obvious physical
damage and kinks, and check that piping does not
touch other unit components.
• Ensure the compressor is mounted on neoprene
isolators with metal spacing sleeves inside. Se-
cured it with nuts that are snug against the metal
spacer sleeves.
• Inspect all electrical connections. Connections
must be clean and tight at the terminals.
Do NOT use the risers to lift the cabinet
assembly.
Do NOT install this unit outdoors.
A compressor/unit comprises a pressur-
ized system. Never loosen threaded joints
while the system is under pressure, and
never open pressurized system parts.
Before servicing, open and tag all discon-
nect switches.
Do NOT install units in a flammable
environment due to the danger of an
explosion.
