Warranty Return Material Procedure
Defective material may not be returned without permission of 
authorized factory service personnel of McQuay International 
in Minneapolis, Minnesota, (763) 553-5330. A “Return 
Goods” tag must be included with the returned material. Enter 
the required information to expedite handling and prompt 
issuance of credits. All parts must be returned to the 
appropriate McQuay facility, designated on the “Return 
Goods” tag. Transportation charges must be prepaid.
The return of the part does not constitute an order for 
replacement. Therefore, a purchase order must be entered 
through the nearest McQuay representative. The order should 
include part number, model number, and serial number of the 
unit involved.
Credit will be issued on customer's purchase order following 
an inspection of the return part and upon determination that the 
failure is due to faulty material or workmanship during the 
warranty period.
Replacement Parts
When writing to McQuay for service or replacement parts, 
refer to the model number and serial number of the unit 
stamped on the serial plate attached to the unit. If replacement 
parts are required, mention the date of installation of the unit 
and date of failure, along with an explanation of the 
malfunctions and a description of the replacement parts 
required.
