NOTES:
1. The replacement Liquid Crystal Display supplied by YORK might not be by the same manufacturer as the original Display. Each Display requires a specific
Display Interface Board (Item 31), Inverter Circuit Board (Item 32), and Display Ribbon Cable (Item 36). Therefore, the Color Display is not available
separately. Service replacement Displays or supporting components must not be arbitrarily selected! Non-compatibility of components will result
in incorrect operation! To assure compatible supporting components, the Display is supplied as a kit (331-01771-000), which contains a replacement
Display and all compatible supporting components on a mounting plate. For future reference, a label attached to the side of the mounting plate (Fig. 4) lists
the YORK part numbers of these compatible components and the required configuration of the Microboard Program Jumpers. These Program Jumpers
must be configured for this Display by a qualified Service Technician following instructions in YORK Service manual 160.69-M1. The contents of the kit
are as follows:

a. Color Display f. Mounting Plate

b. Appropriate Display Interface Board (Item 48) g. Appropriate Display Cable Ribbon
c. Inverter Circuit Board h. All mounting hardware
d. Inverter Cable Assembly j. Installation instructions
e. Adapter Plate

2. Supercedes 031-02418-000.

3. Spare Supressors and Fuses are shipped in cloth bag. They are applied at solenoids and relays located on chiller.

4. Refer to label (FIG. 4) on Display mounting plate for YORK part number of applicable replacement part. Service replacement Display supporting components
must not be arbitrarily selected! Non-compatibility of components will result in incorrect operation!

8. Early vintage chillers were shipped with Stall Transducer 025-39464-000. Later chillers are shipped with Stall Transducer 025-40088-000. These trans-
ducers require different wiring connections. Check the part number of the replacement transducer and make connections at the transducer as follows:

Transducer 025-39464-000
pin 1 - signal out- WHT
pin 2 - ground-BLK
pin 3 - +5vdc supply voltage - RED

Transducer 025-40088-000
pin 1 - +5vdc supply voltage - RED
pin 2 - ground - BLK
pin 3 - signal out - WHT
