INSTALLATION
Retrofit Knockdown
Magnitude WME chillers are relatively easy to disassemble due to the small compressor size, simplified refrigerant piping, and the
absence of a lubrication system with its attendant components and piping. Various knockdown arrangements are available as options
and are ideal for retrofit applications with tight installation clearances.
Bolt-Together Construction - Type A
Chillers are built and shipped completely assembled with bolt-together construction on major components for field disassembly and
reassembly on the job site.
Figure 5: Bolt-Together Construction Option - Representative Schematic
Scope:
•
Site disassembly and reassembly must be supervised or
completed by Daikin Applied service personnel.
•
Unit is fully tested at the factory prior to shipment.
•
The chiller is shipped completely assembled with the
full refrigerant charge, which must be recovered before
breaking any refrigerant connection.
•
The refrigerant charge must be removed from the unit if the
vessels are to be separated. Exert the proper precautions
before attempting any disassembly, assume the condenser
isolation valves may have leaked and that any component
of the chiller may be pressurized with refrigerant.
•
Suction and discharge lines have bolt-on flanges.
•
Motor cooling line is brazed at mechanical connections.
•
Blockoff plates are required to cover any refrigerant
connection left open for extended periods of time. Contact
Daikin Applied service to obtain these parts.
•
Check that no power is being applied to the unit. Before
disconnecting any wire, it is prudent to label its function and
connection point to facilitate reconnection.
•
Unit ships with vessel and/or head insulation, if ordered
.
CAUTION
Standard torque specs must be followed when re-installing
bolts. Contact Daikin Applied service for this information.
