Note:
1. All dimensions are approximate.
2. Standard water nozzles are Schedule 40 pipe size, furnished as welding stub-outs with
grooves, allowing the option of welding, flanges, or use of grooved couplings. Factory-
installed, class 150 (ANSI B16.5, round slip-on, forged carbon steel with 1/16 in. raised
face), water flanged nozzles are optional (add 1/2 in. to nozzle length). Companion
flanges, nuts, bolts, and gaskets are not furnished.
3. One-, two-, and three-pass nozzle arrangements are available only in pairs shown and
for all shell codes. Any pair of evaporator nozzles may be used in combination with any
pair of condenser nozzles. Compact waterboxes on one heat exchanger may be used
with Marine Waterboxes on the other heat exchanger.
4. Condenser water must enter the waterbox through the bottom connection for proper
operation of the sub-cooler to achieve rated performance.
5. Add dimension M as shown in Table 5 or Table 13 according to the isolator type.
