Carrier 09BY006-024 dimensions Rig and Place Unit, Threaded Rod Installed in Bracket

Step 2 Ð Rig and Place Unit

RIGGING Ð The 09BY units are mounted on skids. Leave the unit on the skid until it is in the ®nal position. While on the skid, the unit can be rolled, dragged or forklifted; do not apply force to the unit. Use a minimum of 3 rollers when rolling, and raise from above to remove the skid when unit is in the ®nal position. See Fig. 4 for rigging details.

PLACING THE UNIT Ð Locate the condenser where an adequate supply of outdoor air is available for the unit inlet.

NOTE: Unit inlet and discharge may both be ducted to the outside.

Either provide inlet ®lters to protect the condenser coils, or locate the condenser in an area free from airborne dirt or other foreign material which could clog the coils. For mul- tiple units, allow service clearance (Fig. 3) between units, and locate unit discharges and inlets so that recirculation of condenser air is prevented. Placement area must be level and strong enough to support operating weight of the unit (Table 2). Bolt unit securely in place when unit is positioned and leveled. Fasteners for mounting unit are ®eld supplied.

NOTE: It will be necessary to drill holes in the unit base or side wall where bolts are to be mounted.

IMPORTANT: Use care if rain will enter the unit (if unit is located fully or partially outdoors). DO NOT drill through the unit drain pan or leaks will result.

POSITIONING THE 09BY UNIT Ð Refer to notes in Fig. 3 for typical service clearances.

To suspend the unit, use 4, ®eld-supplied, 1¤2-in. diameter (or larger) threaded rods. Mount 2 heavy channels under the entire width of the unit, allowing them to protrude beyond the width of the unit so that supporting rods can be installed on the channel ends. Attach minimum 1¤2-in. threaded sup- porting rods (®eld-supplied) to channels through a rubber or spring isolator. See. Fig. 5.

DO NOT use rods smaller than 1¤2-in. diameter. Smaller rods may not be strong enough to support the unit. Rods must be securely anchored in ceiling joists.

Use a double hex nut when attaching hanger rods to brack- ets. A single nut could loosen from vibration of the unit. Pitch unit approximately 1¤4-in. toward drain in both directions (length- wise and widthwise) to aid in condensate and/or rain removal.

Before sliding unit into ®nal position, check for clearance to access panels and service area to install piping.

VERTICAL DISCHARGE Ð The 09BY units can be mounted on a ®eld-supplied stand as shown in Fig. 6 for vertical dis- charge. Also, provide a rain drain on the back of the unit.

VIBRATION ISOLATION Ð Units mounted in or above occupied spaces should employ some type of vibration iso- lation. For units that are ¯oor mounted, rubber pads may be located under each unit corner or unit may be mounted on rubber shear isolators or on spring isolators. Unit may be supported by its 4 corners, or a ®eld-supplied support rail may be used for each side. Size isolators with the corner weights shown in Fig. 3. Units may also be suspended from above. See Positioning the 09BY Unit section below and Fig. 5 for recommended support and isolator mounting.

Ductwork attached to the condenser should be isolated from the unit with a ¯exible collar on the inlet and outlet ducts.
