Step 2 — Rig and Place Unit

RIGGING - The 09DK units are designed for overhead rigging and this method should be used Lifting holes are provided in the frame base rails, which are marked for rig ging (see rigging label on the unit). It is recommended that field supplied pipes of sufficient length that extend beyond the frame are passed through the holes. Attach cables, chains, or straps to both ends of the pipes. Use spreader bars or a frame to keep the cables, chains, or straps clear of the unit sides. All cables should run to a central suspension point so that the angle from the horizontal is not less than 45 degrees. See Fig. 2-4 and Tables lA and IB for weight distribution information. Standard coil protection packag ing provides some protection to the unit. Raise and set the unit down carefully.
Domestic Units With No Overhead Rigging— Standard con denser packaging consists of coil protection only. Skids are not provided as part of the standard packaging. If overhead rigging is not available at the jobsite, place the unit on a skid or pad by using jacks at the rigging points before drag ging or rolling. When rolling, use a minimum of 3 rollers. When dragging, pull the pad or skid.
Do not apply pressure
to the unit. Raise from above to lift off the pad or skid
when in final position. See rigging section above for more information.
Export and Domestic Units With Skids— All export units are mounted on skids with vertical coil protection. Leave the unit on the skid until it is in the final 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 final position. See preceding rigging proce dure for more information.
A CAUTION
To avoid damage to units, do not forklift them unless they are attached to skids designed for forklifting. Fork lift trucks used to lift units on skids must have forks a minimum of 60 in. (1524 mm) long.

Step 3 — Complete Refrigerant Piping

GENERAL — All field leak and pressure testing should be in accordance with local code requirements. If a local code does not exist, use ASHRAE (American Society of Heat ing, Refrigeration and Air Conditioning Engineers) Stand ard 15, Safety Code for Mechanical Refrigeration.
For leak testing procedures, refer to the Carrier
“Refrigerant Service Techniques” book. Form SM-IA
For any parts that need to be removed, use a mini tubing cutter. Perform phos-copper brazing on all field-made con nections while protecting adjacent joints from heat.
Install or replace filter-drier(s). COIL REFRIGERANT PIPING INSTALLATION - Hot
gas and liquid connections are located on the same end and
have a heat-shrunk cap, which ensures a clean joint for field piping. The coil circuiting is designed to provide several selections of coil splits to satisfy various applications (See Table 2), with piping connections made in the field. In all cases where circuits are field connected, the piping connec tions should be made within the unit cabinet The hot gas lines should enter and the liquid lines should leave the con denser at the header end of the unit.
A tubing package for headering, including two fan cycle
pressure switches (FCPSs) and hardware, is provided for the 100, 50/50, and nominal 67/33% (054-084 only) con denser coil circuiting options. The tubing also provides ports for easy FCPS installations. The ports come with a
1/4-in. male flare fitting and check valve for each FCPS
replacement. Tubing and FCPSs are field installed regard less of circuiting. Tubing packages are not offered for the 33/33/33% and 33/33/17/17% coil circuiting options; tub ing for these coil circuit options must be field fabricated and installed. See Fig. 5-7 for tubing package contents
NOTE. 67/33, 33/33/33 and 33/33/17/17% represent aver age coil split combinations. Refer to sections below for ac tual values for your particular coil split combination. Note that 09DK094 units can only have 100% or 50/50% splits.
PLACING THE UNIT — Locate the condenser where an adequate supply of outdoor air is available for the unit in let. Do not locate where the possibility of air recirculation exists, such as under a roof overhang. Also, locate the con denser in an area free from airborne dirt or other foreign material which could clog the condenser coils. Refer to Fig. 2-4 for airflow clearances For multiple units, allow 8 ft (2440 mm) separation between units for airflow and service. Placement area must be level and strong enough to support operating weight of the unit (Fig. 2-4 and Tables lA and IB). It is recommended to bolt unit securely to pad when unit is positioned and leveled. Fasteners for mounting unit are field supplied. If vibration isolators are required for a particular installation, refer to the unit weight distribution data tables in Fig. 2-4 to help select the proper isolators.
Table 2 — Coil Circuiting Options
09DK
054 064 074 084 094
100% 50/50% 66/34 100% 50/50% 66/34 100% 50/50% 100% 50/50% 67/33 100% 50/50%
IMPORTANT: With the 67/33, 33/33/33, and 33/33/
17/17% capacity split options, 3 or 4 FCPSs are used For these applications, an accessory fan control kit is required. See accessory installation instmctions for more information.
Figure 8 shows a typical piping application for a condenser with a multiple-split system. Figure 9 shows the typical field piping arrangements for the 09DK units. See Fig. 10 and
11 for coil connection details. Figures 12 and 13 show typ-
*,ical factory supplied coil circuiting and typical field in
stalled 67/33% coil split circuiting, respectively.
