1.3 SUBMITTALS
A Submittals shall include the following:
1 Dimensioned plan and elevation view, including required
clearances, and location of all field piping and electrical
connections.
2 Summaries of all auxiliary utility requirements such as:
electricity, water, air, etc. Summary shall indicate quality
and quantity of each required utility.
3 Diagram of control system indicating points for field
interface and field connection. Diagram shall fully depict
field and factory wiring.
4 Manufacturer's certified performance data at full load
plus IPLV or NPLV.
5 Installation and Operating Manuals.
1.4 QUALITY ASSURANCE
A Regulatory Requirements: Comply with the codes and
standards in Section 1.2.
B Chiller manufacturer plant shall be ISO Certified.
C The chiller shall be tested to job conditions on an AHRI
qualified test stand at the manufacturer's plant.
1.5 DELIVERY AND HANDLING
A Chillers shall be delivered to the job site completely
assembled and charged with refrigerant R-134a and be
shipped on skids with a weather resistant cover.
-- OR --
A (Type I Knockdown, WME only) The compressor, suction
and discharge piping, VFD power panel and touchscreen
shall be removed and shipped separately. All wiring and
piping shall remain attached where possible. The remaining
loose parts shall be packaged in a separate crate. The unit is
to be run-tested at the factory and shipped with a helium
holding charge, evaporator insulated and a kit for
compressor insulation. Contractor shall leak test, evacuate
and charge with refrigerant after reassembly.
--OR--
A (Type II Knockdown, WME only) The compressor, VFD
power panel, wiring and interconnecting piping shall be
removed and shipped separately. The unit shall be run-
tested at the factory. The compressor and vessels shall ship
with a helium holding charge, the evaporator insulated and
a kit for compressor insulation included. Contractor shall
leak test, evacuate and charge with refrigerant after
reassembly.
--OR--
A (Type III Knockdown, WME only) The units shall be
shipped fully assembled, factory charged, run-tested,
insulated and painted; ready for disassembly at the job site.
The unit shall have vessel bolt-on connection brackets,
discharge line bolt-on flanges at the condenser, touch-up
paint and stick-on wire ties. Site disassembly and
reassembly must be factory supervised. Contractor shall
leak test, evacuate and charge with refrigerant after
reassembly.
--OR--
A (Type IV Knockdown WMC only) The compressor and
VFD power panel shall be removed at the factory and
shipped on skids. The stripped vessel stack shall be shipped
as a single piece. Discharge piping, liquid line and the
compressor cooling lines shall be removed and crated. All
associated wiring and piping possible will remain on the
vessel stack. The unit shall be shipped with a holding
charge of helium. Contractor shall leak test, evacuate and
charge with refrigerant after reassembly
-- OR --
A (Type V Knockdown, WMC only) The unit shall be
delivered to the job site completely assembled and charged
with refrigerant (pumped down into condenser) and ready
for field knockdown, as determined by the installing
contractor. Contractor shall leak test, evacuate and charge
with refrigerant after reassembly
B Comply with the manufacturer's instructions for rigging
and transporting units. Leave protective covers in place
until installation.
1.6 WARRANTY
A The chiller manufacturer's warranty shall cover parts and
labor costs for the repair or replacement of defects in
material or workmanship for a period of one year from
equipment startup or 18 months from shipment, whichever
occurs first.
