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

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.

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.
