Note:
1. All dimensions are approximate.
2. For compact waterboxes, see Figure 18, determine overall unit length by adding
waterbox depth to tube sheet length.
3. Water nozzles can be located on either end of unit. Add 13 mm (1/2 in.) to nozzle length
for flanges connections.
4. To determine overall height, add 22 mm (7/8 in.) for isolators.
5. Use of motors with motor hoods may increase overall unit dimensions.
