1. Support plate 2. Tube sheet Note: The isolation package includes 4 shear flex pads. 26 Fig. 13 - Standard isolation 3.4.3 - Install spring isolation Spring isolation may be purchased as an accessory from Carrier for field installation. It may also be field supplied and installed. Spring isolators may be placed directly under machine support plates or located under machine soleplates. See Fig. 15. Obtain specific details on spring mounting and machine weight distribution from job data. Also, check job data for methods to support and isolate pipes that are attached to spring isolated machines. 1. See notes 3. Support plate 4. Tube sheet 5. Jacking screw (see note 3) 3.

The water pipes must not transmit any radial or axial force to the heat exchangers nor any vibration. The water supply must be analysed and appropriate filtering, treatment, control devices, isolation and bleed valves and circuits built in, to prevent corrosion, fouling and deterioration of the pump fittings. Consult either a water treatment specialist or appropriate literature on the subject. 3.5.1 - Install water piping to heat exchanger Install piping using job data, piping drawings, and procedures outlined below. A typical piping installation is shown in Fig. 16. CAUTION: Factory-supplied insulation is not flammable but can be damaged by welding sparks and open flame. Protect insulation with a wet canvas cover. CAUTION: Remove chilled and condenser water sensors and probes before welding connecting piping to the connections. Refer to Fig. 11. Replace sensors and probes after welding is complete. 1. Offset pipe flanges to permit removal of waterbox cover for maintenance and to provide clearance for pipe cleaning. No flanges are necessary with marine waterbox option; however, water piping should not cross in front of the waterbox or access will be blocked. 2. Provide openings in water piping for required pressure gauges and thermometers. For thorough mixing and temperature stabilization, wells in the leaving water pipe should extend inside pipe at least 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 flanges. 5. Use flexible connections to reduce the transmission of vibrations. 6. Water flow direction must be as specified in Fig. 16. NOTE: Entering water is always the lower of the 2 nozzles. Leaving water is always the upper nozzle for cooler or condenser. 7. Water flow switches must be of vapour-tight construction and must be installed on top of pipe in a horizontal run and at least 5 pipe diameters from any bend. 8. Install waterbox vent and drain piping in accordance with individual job data. All connections are 3/4 -in. FPT. 9. Install waterbox drain plugs in the unused waterbox drains and vent openings. 10. Install optional pumpout system or pumpout system and storage tank.
