Carrier 19EX installation instructions Typical 17EX Installation

COMPONENT DISASSEMBLY

To 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 elbow and attach to the hoist. Remove bolting at ¯anges, (Fig. 6, Items 1 and 3). Detach the elbow.

4.Unbolt discharge ¯ange to the condenser at ¯ange (Fig. 8, Item 3). Cut copper lines (Fig. 6, Items 7, 8, and 9).

5.Disconnect and detach the economizer vent line (Fig. 8, Item 4). Unbolt the line at ¯ange (Fig. 8, Item 2).

6.On 19EX machines, disconnect the motor cooling drain line at ¯ange (Fig. 8, Item 5).

7.Disconnect wiring to the control center and power panel.

8.Connect rigging to the compressor.

9.Unbolt compressor from the utility vessel (Fig. 7, Items 2, 4, and 5).

10.Hoist the compressor off of the unit.

11.If the compressor is to be transported or set down, the base should be bolted to sections of 4 in. x 6 in. lumber.

To Separate Condenser from the Machine

1.Unbolt ¯ange (Fig. 6, Item 3).

2.Unbolt ¯ange (Fig. 6, Item 4).

3.Cut copper pipe (Fig. 6, Item 7).

4.Unbolt hot ¯ange (Fig. 7, Item 1).

5.Connect rigging to all corners of the condenser.

6.Unbolt condenser feet (Fig. 8, Items 1 and 6).
