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 specic 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
Daikin Rooftops use the following Copeland Scroll
Compressors.
1. Tandem compressors, basically two compressors
specically manufactured by Copeland into a single
assembly.
2. Trio compressors, basically three single compressors
factory piped in parallel with equalization lines.
All Daikin Rooftop products include a rst-year parts only
warranty. The warranty period extends 12 months from startup
or 18 months from date of shipment, whichever comes rst.
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. Copeland does offer
quick ship options though their wholesalers. However, if
a portion of a tandem or trio is being replaced, Copeland
cannot provide the piping kit, so labor will be more difcult
(See Scroll Compressor Piping on page 134.)
Both sources can be used, at the customer’s discretion, within
the rst year warranty and with the following limitations.
1. RPS 035D to 068D—Only the failed portion of the
tandem may need replacement.
2. RPS 070D to 140D—Only the failed portion of the trio
may need replacement.
Replacing a Portion of a Tandem or Trio
The decision to replace the failed portion of the tandem or trio,
as opposed to replacing the entire tandem or trio, must be
decided based on the following.
1. In warranty: Warranty only covers replacement of the
failed portion of the tandem or trio. Either source may be
used.
2. Out of warranty: The customer decides whether to
replace the entire tandem/trio or just a portion and either
source may be used.
When replacing an “in warranty” compressor through
a Copeland Wholesaler, take the failed compressor to
the wholesaler for an over-the-counter or an advanced
replacement exchange. Credit is issued by Copeland on the
returned motor compressor upon receipt and factory inspection
of the inoperative motor compressor. In this transaction, be
certain that the motor compressor is denitely defective.
If a motor compressor is received from the eld that tests
satisfactorily, a service charge plus a transportation charge will
be charged against its original credit value.
If there was a delay in the startup of the equipment and the
rst-year warranty (Copeland) has expired on the compressor,
within the 18-month-from-shipment warranty, order the
replacement compressor through the Daikin Parts Department
(Minneapolis).
1. Contact the Daikin Parts Department for compressor
availability.
2. Send a completed parts order form to the Daikin Parts
Department.
3. The Parts Department processes the order and the
compressor is shipped from our Dayton, OH warehouse
via ground transportation. If next-day air is required,
indicate this on the parts order form and a freight charge
will be billed to your account. Air freight costs are not
covered under the Daikin warranty.
4. After the failed compressor is replaced, return it to Daikin
with a Return Goods Tag attached, which you will receive
in the mail. It must be attached to the compressor. The
Return Goods Tag has instructions on where to send the
compressor. If the compressor is not returned, you will be
billed for the replacement compressor.
5. Consideration may be given at this time to a compressor
teardown analysis, depending on the history of failures.
