Table 2: Additional operating height clearance
Type of chiller mounting M
Neoprane pad isolators 1 in. (25 mm)
Spring isolators 1 in. deflection 1 in. (25 mm)
Direct mount 3/4 in (19 mm)
Note:
1. All dimensions are approximate. Certified dimensions are available on request.
2. For Marine Waterboxes (shown above), determine overall unit length by adding waterbox
depth to tube sheet length. For Compact Waterboxes, see Table 9.
3. Water nozzles can be located on either end of unit. Add 1/2 in. to nozzle length for flanges
connections
4. To determine overall height, add dimension "M" for the appropriate isolator type. See
Table 2.
5. Use of motors with motor hoods may increase overall unit dimensions. Add 6 in. for 5DJ
size motor.
6. The dimension B is defined by the largest motor available in the unit. Ask for specific
drawing to check the overall unit dimension.
