2. 

All dimensions are approximate. Certified dimensions are available upon request.

3.  Standard water nozzles are Schedule 40 pipe size, furnished as welding stub-outs with ANSI/AWWA C-606 grooves, allowing the option 

of welding, flanges, or use of ANSI/AWWA C-606 couplings. Factory-installed, class 150 (ANSI B16.5, round slip-on, forged carbon steel 

with 1.6 mm raised face), water flanged nozzles are optional (add 13 mm to nozzle length). Companion flanges, nuts, bolts, and gaskets 

are not furnished.

4.  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.

5.  Water must enter the waterbox through the bottom connection to achieve rated performance.
