Serial Number Identification
The serial number tag is located on the top flange of the unit frame just left of the
control panel and in the upper right corner of the electrical control panel.
Ordering Replacement Parts
Prompt service can be rendered on replacement part orders if the following information
is given:
1. The serial number must be given when ordering replacement parts. Part
numbers should be verified per the bill of materials associated with the serial
number to ensure that correct replacement parts are ordered.
2. State the exact part number needed. Do not order by index numbers, as
index numbers are repeated throughout this manual and if used for ordering
parts will necessitate time consuming correspondence.
3. State the exact quantity needed.
4. State the preferred type of transportation.
All replacement parts are to be ordered through an authorized distributor. Insist on
Genuine Quincy Parts only! Failure to do so may void your warranty.
