Service and Warranty Procedure
Service and Warranty Procedure
Replacement Parts
When writing to
Daikin
for service or replacement parts,
provide the model number, serial number, and unit part
number of the unit as stamped on the serial plate attached to
the unit. For questions regarding wiring diagrams, it will be
necessary to provide the number on the specific diagram. If
replacement parts are required, include the date of unit
installation, the date of failure, an explanation of the
malfunction, and a description of the replacement parts
required.
Scroll Compressor (sizes 15 to 105C)
Daikin
Rooftops use the following Copeland Scroll
Compressors.
1
Single compressors, one per refrigerant circuit
2
Tandem compressors, basically two compressors
specifically manufactured by Copeland into a single
assembly.
3
Trio compressors, basically three single compressors
factory piped in parallel with equalization lines.
All
Daikin
Rooftop products include a first-year parts only
warranty. The warranty period extends 12 months from
startup or 18 months from date of shipment, whichever comes
first. Labor to install these parts is not included with this
warranty. Compressors are considered a part and are included
in this standard warranty.
Scroll service replacement compressors for
Daikin
Rooftop
Units can be obtained from the following two sources:
•
Daikin
Service Parts maintains a stock of replacement
compressors.
•
Copeland Refrigeration has stocking wholesalers throughout
the U.S. who maintain a limited stock of replacement scroll
compressors. The stock of single compressors is much better
than the stock of tandems “tandem/trio ready”, single
compressors. Trios are almost never in wholesaler stock and
are not recommended for use on
Daikin
Rooftops due to
piping interference. Copeland does offer quick ship options
though their wholesalers.
Both sources can be used, at the customer’s discretion, within
the first year warranty and with the following limitations.
1
RPS 018 to 020C (with single compressors. No
limitations).
2
RPS 025 to 030C (with single and tandem compressors).
a
If any part of the tandem fails then the entire tandem
must be replaced. Both sources are acceptable.
b
Single compressor. No limitations.
3
RPS 036C (with tandem compressors).
a
Circuit #1 tandem - If any part of the tandem fails then
the entire tandem must be replaced. Both sources are
acceptable.
b
Circuit #2 tandem–Each of the tandem’s compressors
have a rotalock and only the failed portion of the tandem
may need replacement.
3
RPS 040 to 060C—Each of the tandem’s compressors have
a rotalock and only the failed portion of the tandem may
need replacement.
4
RPS 070 to 105C—Each of the trio compressors have a
rotalock and only the failed portion of the trio may need
replacement.
5
Only a “tandem or trio ready” compressor, with oil
equalizer lines, can be used to replace a portion of the
tandem or trio.
Reciprocating Compressors (sizes 115 to
135C)
Daikin
Rooftops use Copeland Discus™ compressors
mounted in “tandem.”
Tandem compressors are basically two single compressors
factory piped in parallel with equalization lines.
All
Daikin
Rooftop products include a first year parts only
warranty. The warranty period extends 12 months from start-
up or 18 months from date of shipment, whichever comes first.
Labor to install these parts is not included with this warranty.
Compressors are considered a part and are included in this
standard warranty.
If the equipment experiences a compressor failure within the
first year parts warranty period or is a “dead” on arrival (DOA)
compressor at start-up, the failed compressor is covered under
the first year parts warranty. To receive a replacement
compressor:
1
Notify the local (Copeland) wholesaler of the failure and
provide the compressor model and serial number.
2
The customer/contractor picks up the replacement
compressor from the wholesaler.
3
After removing the failed compressor from the equipment,
return it to the local wholesaler for credit on the
replacement compressor.
4
Consideration may be given at this time to a compressor
teardown analysis, depending on the history of failures.
