NIH Ð Nozzle-in-Head

*The 150 psig (1034 kPa) 2-pass waterbox cover weights are included in the dry weight shown in Table 1.

²Two different waterbox covers are present on 2-pass machines. The weight shown in this table represents the weight of the waterbox cover that contains the nozzles. A blank waterbox cover is also present on 2-pass units. The weight of the blank waterbox cover is identical to the weight of the same size marine waterbox cover. Refer to Table 11.

Install Machine Supports

INSTALL STANDARD ISOLATION Ð Figures 10 and 11 show the position of support plates and shear ¯ex pads, which together form the standard machine support system.

INSTALL OPTIONAL ISOLATION (if required) Ð Un- even ¯oors or other considerations may dictate the use of soleplates and leveling pads. Refer to Fig. 10 and 11.

Level machine by using jacking screws in isolation sole- plates. Use a level at least 24 in. (600 mm) long.

For adequate and long lasting machine support, proper grout selection and placement is essential. Carrier recommends that only pre-mixed, epoxy-type, non-shrinking grout be used for machine installation. Follow manufacturer's instructions in applying grout.

1.Check machine location prints for required grout thickness.

2.Carefully wax jacking screws for easy removal from grout.

3.Grout must extend above the base of the soleplate and there must be no voids in grout beneath the plates.

4.Allow grout to set and harden, per manufacturer's in- structions, before starting machine.

5.Remove jacking screws from leveling pads after grout has hardened.

INSTALL SPRING ISOLATION Ð Field-supplied spring isolators may be placed directly under machine support plates or be located under machine soleplates. Consult job data for speci®c arrangement. Low pro®le spring isolation assem- blies are recommended so that the machine is kept at a con- venient working height inside of the tube sheet.

Obtain speci®c details on spring mounting and machine weight distribution from job data. Also, check job data for methods for supporting and isolating pipes that are attached to the spring-isolated machines.
