This equipment is a relatively complicated apparatus.
During rigging, installation, operation, maintenance,
or service, individuals may be exposed to certain com-
ponents or conditions including, but not limited to:
heavy objects, refrigerants, materials under pressure,
rotating components, and both high and low voltage.
Each of these items has the potential, if misused or
handled improperly, to cause bodily injury or death. It
is the obligation and responsibility of rigging, instal-
lation, and operating/service personnel to identify and
recognize these inherent hazards, protect themselves,
and proceed safely in completing their tasks. Failure
to comply with any of these requirements could result
in serious damage to the equipment and the property in

tions and are not followed.
Highlights additional information useful
to the technician in completing the work
being performed properly.
External wiring, unless specied as an optional connection in the manufacturer’s product line, is not
to be connected inside the control cabinet. Devices such as relays, switches, transducers and controls
and any external wiring must not be installed inside the micro panel. All wiring must be in accor-
dance with the manufacturer's published specications and must be performed only by a qualied
electrician. The manufacturer will NOT be responsible for damage/problems resulting from improper
connections to the controls or application of improper control signals. Failure to follow this warn-
ing will void the manufacturer’s warranty and cause serious damage to property or personal injury.
WARNING: This product can expose you to chemicals including formaldehyde, which is known
to the state of California to cause cancer. For more information, go to www.P65Warnings.ca.gov.

After installing the unit, show the user
how to turn off the electricity to the unit.
Point out control and switch locations for
turning off the electricity.
Ensure the user understands the impor-
tance of following all safety precautions.
NOTICE AND DISCLAIMER
This unit contains refrigerant installed by the factory
that is approved for use in the unit’s intended country
of installation or market. Distributors are only autho-
rized to provide refrigerants that have been approved
for use in the countries or markets they serve.
The refrigerant used in this unit is identified on the
unit's nameplate and in this manual. Any additions of
refrigerant into this unit must comply with the coun-
try’s requirements with regard to refrigerant use and
should be obtained from manufacturer approved dis-
tributors. Use of unapproved refrigerant substitutes
will void all warranties and can cause injury or death.
Disclaimer
Customer modifications to certified products are pro-
hibited. If performed without the express written ap-
proval of the manufacturer, modifications will void
all warranties (expressed or implied) and may result
in hazardous situations resulting in equipment damage,
serious physical injury or property damage, or death.
The manufacturer has certified the product as being
compliant with applicable government and/or industry
standards. Product certification is designated either on
the product itself or in the product literature. The cer-
tification mark identifies the applicable standards as
well as the Nationally Recognized Test Lab (NRTL) or
other testing facility that conducted the testing, where
applicable.
If changes are made to the product, an engineering re-
view is required to assess the impact to the product cer-
tification. In some instances, the changes may require
that the NRTL or testing facility review and re-approve
the product by means of a field or site inspection and
certification.
Modifications may invalidate product certifications or
violate country standards. Any person or entity making
changes to the product is responsible for obtaining the
required engineering review and approval, as well as
covering certification and other related costs.
Unauthorized customer modifications to certified
products are prohibited for the following reasons:
A. Modications may create hazards that could result
in death, serious injury, or equipment damage.
B. Modications will void product warranties.
C. Modications may invalidate product certica-
tions and may violate country standards. Country
standards may require that only certied products
be used in certain applications, and modications
that result in the loss of product certication may
violate those standards.
PRE-INSTALLATION
Literature
Review this Installation, Operation, and Maintenance
(IOM) manual prior to installation. After installing the
unit, give this IOM to the end user. If help is needed
with any of the installation instructions or matters re-
lating to the unit, contact the sales office where you
bought the unit. You may also refer to the unit rating
plate for a contact name.
Shipping
Cabinets and risers ship in one of the following con-
figurations:
• Cabinets are stacked on their side with risers at-
tached. Chassis ship on separate skids.
• Risers ship loose, packaged in boxes and sorted
by oor. Cabinets ship upright up to four per skid.
Chassis ship on separate skids.
• Risers ship loose, packaged in boxes, and sorted
by oor. Cabinets ship upright on skids with chas-
sis inside the cabinet. Chassis electrical and water
connections are not installed. The chassis is se-
cured to the service panel. Remove the screws be-
fore removing the service panel and chassis.
The cabinet must remain standing upright. Do not
place cabinets on their side with the chassis inside.

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 specic 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.
