Service and Warranty Procedures
Service and Warranty Procedures
Replacement Parts
MicroTech III controllers are factory tested and documented
prior to shipping. This is to assure the functionality of the
controller and the unit and prevent dead on arrival controllers.
Any miswiring of the MicroTech III controller that damages it
in any way, such as blown internal fuse, will not be covered
under warranty.
When contacting 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, 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
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.
All Compressors
Replacement compressors for Daikin Rooftop Units can be
obtained from the Daikin Service Parts department.
The decision to replace the failed portion of the compressor
tandem, as opposed to replacing the entire tandem, must be
decided based on the following.
1 .
In warranty:
Warranty only covers replacement of the
failed portion of the tandem.
2 .
Out of warranty:
The customer decides whether to
replace the entire tandem or just a portion.
3 .
Some equipment may include the extended 2nd - 5th
year compressor warranty option.
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 compressors are 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
Parts Department 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.
In-Warranty Return Material Procedure
Material other than compressors may not be returned except
by permission of authorized personnel of McQuay International
at Minneapolis, Minnesota.
A “return goods” tag will be sent to be included with the
returned material. Enter the information as called for on the tag
in order to expedite handling at out factories and issuance of
credits. All parts shall be returned to the factory designated on
the return goods tag, transportation charges prepaid.
The return of the part does not constitute an order for
replacement. A purchase order for the replacement part
must be entered through your nearest Daikin representative.
The order should include the component’s part number and
description and the model and serial numbers of the unit
involved.
If it is determined that the failure of the returned part is due to
faulty material or workmanship within the standard warranty
period, credit will be issued on the customer’s purchase order.
NOTE:
1. Unit does not require high pressure switch testing
2. Refrigerant pressures can be checked from the
MT III controller. Refrigerant gages are not needed.
3. Ensure proper unit phasing
4. Compressor 3 might not operate during startup
due to ambient conditions and compressor
operating envelope.
