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.
Compressor Arrangements
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 018C to 020C (with single compressors, no
limitations).
2.
RPS 025C 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.
4.
RPS 040C to 060C—Each of the tandem’s compressors
have a rotalock and only the failed portion of the tandem
may need replacement.
5.
RPS 070C to 105C—Each of the trio compressors have
a rotalock and only the failed portion of the trio may need
replacement.
6.
Only a “tandem or trio ready” compressor, with oil
equalizer lines, can be used to replace a portion of the
tandem or trio.
