Compressor Dimensions
NOTE:
Drawings, dimensional values, and other information
may change depending on options or configurations
selected. Refer to the as-built submittal drawings
provided by a Daikin Applied sales representative for
configuration-specific details.
The compressor dimensions vary by model. All dimensions and
weights per compressor are listed in

Compressor Removal and Re-
Attachment Instructions
Follow the steps listed to remove and re-attach each
compressor.
Compressor Removal Preparation
1. Prior to detaching or unsweating any connections, verify
there is no pressure or charge in the lines.
2.
Close shut-off valve at condenser liquid line outlet.
3.
Close all other related shut-off valves.
4.
Remove the oil eductor line, providing a blockoff cap at
compressor and evaporator connection points.
5.
Remove the liquid injection line, providing a blockoff
cap at the compressor gear housing and condenser
connection points; see
Figure 25
.
6.
Remove the motor drain lines, providing block off
caps at the compressor motor housing and evaporator
connections. The 1/4” vent line will need to be braced in
a minimum of 2 places to prevent damage.
7.
Remove oiler cooler lines, providing block off caps at the
the compressor gear housing connections; see
Figure
25
. Blockoffs will also be needed at the evaporator and
condenser connections.
8.
Remove hot gas bypass line, providing blockoff caps at
the discharge nozzle and evaporator connection points.
Care must be taken when brazing or removing lines to
not apply excessive heat to valve seats; use cooling
wraps at all times on valve components.
9. Disconnect power leads from starter.
10. Loosen and remove bolts on the top side of the
compressor discharge nozzle (see
Figure 26
, flag #5).
11.
Loosen and remove bolts at flange on condenser and
remove discharge piping.
12.
Cover openings with blockoffs to prevent foreign objects
entering.

NOTE:
Graphic is representative. Line locations may vary by
unit configuration.
Compressor Removal
1. Loosen and remove bolts/screws on either side of the
suction elbow (see
Figure 26
).
2. Loosen the (8) bolts from the compressor’s bottom
mounting feet (see
Figure 26
).
3. Use lifting straps on the compressor assembly
Figure 23
to
rig compressor for removal. Compressor dimensions
and weights are given in
Table 8.
