Carrier 38AH044-084 specifications Rigging Center of Gravity Ð in. mm, Unit, Module

The placement area must be level and strong enough to support the operating weight of the unit (see Table 3A or 3B). When unit is in proper location, use of mounting holes in base rails is recommended for securing unit to supporting structure. For mounting unit on vibration isolators, a perim- eter support channel between the unit and the isolators is recommended. Fasteners for mounting unit are ®eld sup- plied. Be sure to mount unit level to ensure proper oil return to compressors.

Units 38AH094-134 Ð Refer to Fig. 3-6 for air¯ow clearances. Recommended minimum clearances are 6 ft (1829 mm) for unrestricted air¯ow and service on sides of unit, 5 ft (1524 mm) on ends, and unrestricted clear air space above unit. Provide ample space to connect liquid and suc- tion lines to indoor unit. For multiple units, allow 8 ft (2440 mm) separation between units for air¯ow and service.

Do not forklift these units unless the unit is attached to a skid designed for forklifting.

The placement area must be level and strong enough to support the operating weight of the unit. See Table 4A or 4B. Refer to the following paragraphs for the proper place- ment of the unit.

Units 38AH094,104 Ð For mounting units on vibration iso- lators, a perimeter support channel is required between the unit and the support isolators. The perimeter support chan- nel must be sized to support the fully assembled unit. Do not

support units on individual isolation supports. Support chan- nel, hardware, and fasteners are ®eld supplied. When unit is in proper location, level unit and bolt into position with ®eld- supplied bolts.

Units 38AH124,134 Ð For ease of shipment and handling, unit 38AH124 is shipped as 2 modules (124A and 124B) and unit 38AH134 is shipped as 2 modules (134A and 134B). The modules must be connected at the ®nal installation site with the factory-shipped piping and sheet metal trim kit mounted on Module 124A or 134A. See Fig. 7.

Do not move assembled 38AH124 or 134 units as a single assembly. Always move modules individually during in- stallation or at any other time.

Mark installation site for placement of Modules 124A and 124B or Modules 134A and 134B. See Table 4A or 4B for ®nal assembled dimensions. A service space of 24 in. (610 mm) is required between the 2 modules for piping and sheet metal trim installation.

Place Module 124A or 134A in position, ensuring that the control box is at the end opposite the service space. See Fig. 8.

Remove sheet metal and tubing from Module 124A or 134A sheet metal trim kit (Fig. 7). Remove sheet metal cover pan- els from return-bend end of unit facing the service space. See Fig. 8. These panels may be discarded or saved for reinstallation if module is moved from site. See Fig. 9.
