Reassembly
This section provides technical specifics for the chiller, including weights, dimensions, and torque
requirements.
Note:
The YVAM chiller is completely factory assembled and does not require any field
assembly. For occasions where field disassembly or reassembly may need to be conducted
for any reason, the following sections are intended to provide technical details for a qualified
Johnson Controls Service representative to safely complete these tasks.
