Retrofit Knockdown
It is estimated that fifty percent of retrofit applications
require partial or complete disassembly of the chiller. WWV
chillers are relatively easy to disassemble due to the small
compressor size and simplified refrigerant piping. Two
knockdown arrangements, Type A and Type B, are available
as options. All major components (evaporator, condenser,
compressor, unit control panel and compressor) are designed
with lifting holes or eyebolts that should be utilized in moving
these pieces individually.
Type A Knockdown, “Bolt-Together
Construction”
Chillers are built and shipped completely assembled with
bolt-together construction on major components for field
disassembly and reassembly on the job site.
Type A Scope
:
• Chiller components are manufactured with bolt-together
construction designed for field disassembly and
reassembly on-site.
•
Suction and discharge lines have bolt-on flanges.
• Unit ships with vessel and/or head insulation.
• Unit ships with full factory refrigerant charge in the chiller.
• Unit ships with replacement refrigerant gaskets and
O-rings, stick-on wire ties, and touch-up paint.Unit is fully
tested at the factory prior to shipment.
• Site disassembly and reassembly must be supervised or
completed by Daikin Applied service personnel.
• Blockoff plates are required to cover any refrigerant
connection left open for extended periods of time. Contact
Daikin Applied service to obtain these parts.
•
Ideal for retrofit applications where site diassembly is
needed due to installation clearances.

Type B Knockdown, “Bolted
Construction, Shipped as Parts”
Compressor(s), power boxes and control box are removed at
the factory and shipped on separate skids; combined vessel
stack is shipped together as a sub-assembly.
Type B Scope
:
• All associated piping and wiring remain attached, if
possible.
• All free piping ends are capped.
• Unit ships with vessel and/or head insulation, if ordered.
• Refrigerant will not be shipped with the chiller and must
be procured by others.
• Compressor(s) and vessels receive an inert gas holding
charge.
• Unit ships with replacement refrigerant gaskets and
O-rings, stick-on wire ties, and touch-up paint.
• Unit is fully tested at the factory prior to shipment.
• Site reassembly must be supervised or completed
by Daikin Applied service personnel. Cost for unit
resassembly and supervision by Daikin Applied service
is not included in the purchase price of the equipment.
Contact Daikin Applied service for pricing.
•
Ideal for retrofit applications where it is desired that the
compressor(s), power box, and control box be removed
at the factory, prior to shipment, and where refrigerant
may be secured by others.
