Type A Knockdown Disassembly
Removal of specic components only may be necessary for job
site installation. Steps outlined below illustrate knockdown of
compressor, all refrigerant lines and electrical items. Additional
knockdown details will be shipped with the unit in the control
panel. During disassembly, save gaskets for block os and bolts,
washers, and nuts for use later to install block o plates.
CAUTION
Standard torque specs must be followed when re-installing
bolts, unless otherwise stated for specic components. Contact
Daikin Applied service for this information.
1. Recover refrigerant charge from the unit.
2. Remove discharge line at compressor and condenser
connections.
3. Remove liquid line at evaporator and condenser
connections, leaving the liquid line clamp on the top of the
condenser.
4. Remove jet pump line at shuto valve on condenser
and evaporator. Reassemble the clamp attached to the
compressor bracket after copper jet pump line is removed.
5. Remove oil line at Rotolock connection on compressor and
condenser connection. Remove support bracket attached
to compressor mounting foot. Leave the clamp and bracket
attached to the oil line.
6. Remove power wire harness assemblies from the bottom of
the VFD to the unit control box and to compressor terminal
box but leave the bus bars, electrical barrier, ground strap,
and ttings installed.

7. Disconnect the thermister wires from the compressor
terminal box and coil them inside the VFD - do not
disconnect from the VFD terminal block. Unbolt VFD from
mounting brackets and use lifting lugs to remove the panel.
8. Disconnect the high pressure switch from the control box
end only and leave connected to the compressor.
9. Remove compressor using lifting lugs and install blockos
on the discharge and suction connections; then remove
suction line.
10. Disconnect all solenoids from the chiller but leave
connected to the control box; the jet pump solenoid
harness should include the solenoid coil.
11. Disconnect the multi-cable connectors from the back side
of the control box. Leave all transducers and ow sensors
installed on the chiller, just remove the cables. Unmount
the control box and use lifting lugs to remove. the control
panel.
12. Ensure vessel blockos are installed at suction, discharge,
and liquid connections as shown in Figure 15. Refer to
detailed knockdown instructions included in the chiller
control panel for discharge line bolt torque specications.
13. Vessels can be further separated at tubesheet braces if
needed, leaving relief valves attached. Use lifting holes in
the tubesheets to properly move vessels.
