Install Vent Piping to Relief Devices
The 19FA chiller is factory equipped with relief devices on the cooler and storage vessels.
Refer to Figure 2 and Table 2 for size and location of relief devices. Vent relief devices to the
outdoors in accordance with ASHRAE 15, latest edition, and all other applicable codes. To
ensure relief valve serviceability of the storage vessel and as required in ASHRAE 15, latest
edition, 3-way valves and redundant relief valves are installed. See Figure 14. Only one half of
the total number of relief valves listed in Table 2 are in service at any time.
