3. Remove the hex head screws from the flanges 

connecting the evaporator tube sheet and condenser 
shell support (see 

Figure 17

). Then remove the screws 

from the flanges connecting the shells.

4. Reassemble the evaporator and condenser shells in 

the reverse order.

Note:

Install the top screws first as these have limited 
clearance and act as dowel pins.

5. Torque all screws to specifications listed in 

Table 2, 

p. 21

.

Optional Hinged Waterboxes

If the chiller includes optional hinged waterboxes, the 
waterboxes and hinge may be removed for installation or 
service.
