The operating charge for each unit isshown in section 2d.1 Physical Data Table.3d: Water System3d.1: Water PipingLocal authorities can advise the installer on the current building and safety codes required forproper installation.Install piping with a minimum of bends and changes in elevation to minimize pressure drop.Consider the following when installing water plumbing to the unit:1. Vibration eliminators to reduce vibration and noise transmission to the building.2. Shut off valves to isolate the unit from the plumbing system during unit servicing.3. Manual or automatic air vents at the high points of the system.4. Install drains at the lowest points in the system.5. Maintaining adequate system water pressure to the water pump.6. Temperature and pressure indicators located close to the unit to aid in unit servicing.7. A strainer or other means of removing foreign matter from the water before it enters the pump.Place the strainer far enough upstream to prevent cavitations at the pump inlet.8. A 40-mesh strainer is required just before the inlet of the condenser. This is important toprevent foreign material from entering and decreasing the performance of the condenser.9. Flush the plumbing system thoroughly before the unit is connected. Perform regular wateranalysis and water treatment, as necessary, on the cold water line to the condenser.10. Perform a preliminary leak check before insulating the plumbing pipe work and filling thesystem.Figure 4: Typical in Field Condenser Water PipingAir ventCondenserInletOutletIsolationvalveStrainer Service and DrainServiceNOTES:1.
