RIG MACHINE COMPONENTS — Refer to instructions on page 5, Fig. 6-8, and Carrier certified drawings for ma- chine component disassembly . IMPOR T ANT : Only a qualified service technician should disassemble and reassemble the machine. After reas- sembly , the machine must be dehydrated and leak tested. When rigging components separately, the ope[...]

COMPONENT DISASSEMBL Y T o Separate Compressor from the Machine 1. Make sure to check that the machine is at atmospheric pressure before disassembly . 2. Since the center of gravity is high on 17EX machines, the motor MUST be removed before rigging the machine. 3. Suction elbow should be rigged separately (Fig. 6, Item 2). Place slings around the e[...]

NOTES: 1. Each chain must be capable of supporting the maximum weight of the machine. 2. = the approximate center of gravity . 3. Maximum possible weight is 88,500 lb (40 166 kg) which includes a maxi- mum of 6,000 lb (2 721 kg) of HFC-134a refrigerant in the storage tank. 17EX FRONT VIEW COOLER SIZE VESSEL LENGTH MAXIMUM WEIGHT LIFTING ANGLE CHAIN[...]
