Connect Piping

NOTE: A ®eld supplied and installed low pro®le isolation is suggested to keep operation height low.

(Field Supplied and Installed)

For adequate and long-lasting machine support, proper grout selection and placement is essential. Carrier recommends that only epoxy-type grout be used for machine installation. Fol- low 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.Back jacking screws off leveling pads after grout has hardened.

INSTALL SPRING ISOLATION Ð Field-supplied spring isolators may be placed directly under machine support plates or located under machine soleplates. See Fig. 17. Consult job data for speci®c arrangement. Low pro®le spring isola- tion assemblies are recommended so that the machine is kept at a convenient 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.

INSTALL WATER PIPING TO HEAT EXCHANGERS Ð Install piping using job data, piping drawings, and proce- dure outlined below. A typical piping installation is shown in Fig. 19.

Factory-supplied insulation is not ¯ammable but can be damaged by welding sparks and open ¯ame. Protect in- sulation with a wet canvas cover.

Remove chilled and condenser water sensors before weld- ing connecting piping to water nozzles. Refer to Fig. 2 and 3. Replace sensors after welding is complete.

1.If the machine is a nozzle-in-head arrangement, offset pipe ¯anges to permit removal of waterbox cover for main- tenance and to provide clearance for pipe cleaning. No ¯anges are necessary with marine waterboxes; however, water piping should not cross in front of the waterbox or access will be blocked off.

2.Provide openings in water piping for required pressure gages and thermometers. Openings should be at least 6 to 10 pipe diameters from the waterbox nozzle. For thor- ough mixing and temperature stabilization, wells in the leaving water pipe should extend inside pipe at least 2 in. (50 mm).

3.Install air vents at all high points in piping to remove air and prevent water hammer.

4.Install pipe hangers where needed. Make sure no weight or stress is placed on waterbox nozzles or ¯anges.

5.Water ¯ow direction information is shown in Fig. 20 and 21.

NOTE: Entering water is always the lower of the two nozzles. Leaving water is always the upper nozzle for cooler or condenser.

6.Water ¯ow switches must be of vapor-tight construction and must be installed on top of the pipe in a horizontal run and at least 5 pipe diameters from any bend.

Differential pressure type ¯ow switches may be con- nected at the nozzle of the waterbox.

7.Install waterbox vent and drain piping in accordance with individual job data. All connections are 3¤4-in. FPT.

8.Install waterbox drain plugs in the unused waterbox drains and vent openings.

9.Install water piping to the optional pumpout system con- denser storage tank as shown in Fig. 20-25.
