INSPECT SHIPMENT — Inspect for shipping damage while unit

is still on shipping pallet. If unit appears to be damaged or is torn

loose from its anchorage, have it examined by transportation

inspectors before removal. Forward claim papers directly to

transportation company. Manufacturer is not responsible for any

damage incurred in transit. Check all items against shipping list.

Immediately notify the nearest Carrier Air Conditioning office if

any item is missing. To prevent loss or damage, leave all parts in

original packages until installation.

Step 2—Provide Unit Support

ROOF CURB — Install accessory roof curb in accordance with

instructions shipped with curb (See Fig. 4). Install insulation, cant

strips, roofing, and flashing. Ductwork must be attached to curb.

IMPORTANT: The gasketing of the unit to the roof curb is critical

for a watertight seal. Install gasketing material supplied with the

roof curb. Improperly applied gasketing also can result in air leaks

and poor unit performance.

Curb should be level to within 1/4 in. (See Fig. 5). This is

necessary for unit drain to function properly. Refer to accessory

roof curb installation instructions for additional information as

required.

SLAB MOUNT — Place the unit on a solid, level concrete pad

that is a minimum of 4 in. thick with 2 in. above grade (See Fig.

6). The slab should extend approximately 2 in. beyond the casing

on all 4 sides of the unit. Do not secure the unit to the slab except

when required by local codes.

GROUND MOUNT — The unit may be installed either on a slab

or placed directly on the ground if local codes permit. Place the

unit on level ground prepared with gravel for condensate dis-

charge.

Step 3—Provide Clearances

The required minimum service clearances are shown in Figs. 2 and

3. Adequate ventilation and outdoor air must be provided. The

outdoor fan draws air through the outdoor coil and discharges it

through the top fan grill. Be sure that the fan discharge does not

recirculate to the outdoor coil. Do not locate the unit in either a

corner or under an overhead obstruction. The minimum clearance

under a partial overhang (such as a normal house overhang) is 36

in. above the unit top. The maximum horizontal extension of a

partial over-hang must not exceed 36 in. For extended overhangs,

provide a minimum clearance of 36 in.

IMPORTANT: Do not restrict outdoor airflow. An air restriction

at either the outdoor-air inlet or the fan discharge may be

detrimental to compressor life.

Do not place the unit where water, ice, or snow from an overhang

or roof will damage or flood the unit. Do not install the unit on

carpeting, tile, or other combustible materials. Slab-mounted units

should be at least 4 in. above the highest expected water and runoff

levels. Do not use unit if it has been under water.

Step 4—Rig and Place Unit

Rigging and handling of this equipment can be hazardous for many

reasons due to the installation location (roofs, elevated structures,

etc.)

Only trained, qualified crane operators and ground support staff

should handle and install this equipment.

When working with this equipment, observe precautions in the

literature, on tags, stickers and labels attached to the equipment,

and any other safety precautions that might apply.

Follow all applicable safety codes. Wear safety shoes and work

gloves.

INSPECTION — Prior to initial use, and at monthly intervals, all

rigging brackets and straps should be visually inspected for any

damage, evidence of wear, structural deformation, or cracks.

Particular attention should be paid to excessive wear at hoist

hooking points and load support areas. Brackets or straps showing

any kind of wear in these areas must not be used and should be

discarded.

INSTALLATION

1. Remove unit from shipping carton. Leave top shipping skid on

the unit as a spreader bar to prevent the rigging straps from

damaging the unit. If the wood skid is not available, use a

spreader bar of sufficient length to protect unit from damage.

2. Position the lifting bracket assembly around the base of the

unit. Be sure the strap does not twist.

3. Place each of the 4 metal lifting brackets into the handholds in

the composite pan.

4. Thread lifting bracket strapping around bottom perimeter of

unit as follows:

a. Open lever of tension buckle (ratchet type).

b. Feed strapping through tension buckle as shown in Fig. 7.

c. Pull strapping through tension buckle unit taut.

d. Snap lever down to lock strap in tension buckle. To release

strapping, squeeze safety latch, lift lever, and pull webbing

outward.
