VENT VALVE

Do not run 120-v wiring into the control center. The control center should only be used for additional extra low-voltage wiring (50 v maximum).

Wiring diagrams in this publication (Fig. 27-31) are for reference only and are not intended for use during actual installation; follow job speci®c wiring diagrams.

INSTALL VENT PIPING TO RELIEF DEVICES Ð The 23XL chiller is factory equipped with relief devices on the cooler and condenser shells. Refer to Fig. 26 and Table 7. Vent relief devices to the outdoors in accordance with ANSI/ ASHRAE-15 (latest addition) Safety Code for Mechanical Refrigeration and all other applicable codes.

To ensure relief valve serviceability and to ful®ll ASHRAE 15, latest edition, 3-way valves and redundant re- lief valves are installed. See Fig. 26. Only one half of the total number of relief valves listed in Table 7 are in service at any time.

Refrigerant discharged into con®ned spaces can dis- place oxygen and cause asphyxiation.

1.If relief devices are manifolded, the cross-sectional area of the relief pipe must at least equal the sum of the areas required for individual relief pipes.

2.Provide a pipe plug near outlet side of each relief device for leak testing. Provide pipe ®ttings that allow vent pip- ing to be disconnected periodically for inspection of valve mechanism.

3.Piping to relief devices must not apply stress to the device. Adequately support piping. A length of ¯exible tubing or piping near the device is essential on spring- isolated machines.

4.Cover the outdoor vent with a rain cap and place a condensation drain at the low point in the vent piping to prevent water build-up on the atmospheric side of the relief device.

Make Electrical Connections Ð Field wiring must be installed in accordance with job wiring diagrams and all applicable electrical codes.

NOTE: The relief valve tree is available on all condens- ers. It is also applicable to Frame 4 machines with accessory isolation packages.

*Relief valve is only available when an optional (factory installed) or accessory (®eld installed) refrigerant isolation package is used.

Do not attempt to start compressor or apply test voltage of any kind while machine is under dehydration vacuum. Motor insulation breakdown and serious damage may result.
