LEGEND NPSHr Net Positive Suction Head Pressure Required NOTE Refer to Fig 1 for option identification Refer to Table 4 for more information Fig 36 Pump Curve II for Hydronic Package Dual Pump Fresh Water 60 PUMP MODIFICATION TRIMMING Since the pumps are constant speed the only way to obtain greater flow with a given pump impeller is to decrease system head This will allow the pump to ride its curve to the right resulting in increased flow If greater flow is necessary consider opening the combination valve Also verify that the strainer is clean and that no unnecessary system resistance is present such as partially closed isolation valves Once the combination valve is set note the stem position If later service work requires the valve to be closed it will be easier to re balance the system if the original balance point is known Increasing system resistance by closing the balancing valve will force the pump to ride its curve to the left resulting in less flow Although this does reduce power consumption slightly it may not be the desirable method of reducing the flow especially if a large reduction is needed The other method for reducing flow on a constant speed pump is impeller trimming The impellers in the pumps provid ed in the 30XA hydronic kit can be easily removed for this purpose Refer to the vendor literature packet supplied with the hydronic package information on Sea

85. 2 Be sure to use a cleaning agent that is compatible with all system materials Be especially careful if the system contains any galvanized or aluminum components Both detergent dispersant and alkaline dispersant cleaning agents are available 3 It is recommended to fill the system through a water me ter This provides a reference point for the future for loop volume readings and it also establishes the correct quan tity of cleaner needed in order to reach the required concentration 4 Usea feeder transfer pump to mix the solution and fill the system Circulate the cleaning system for the length of time recommended by the cleaning agent manufacturer a After cleaning drain the cleaning fluid and flush the system with fresh water b Aslight amount of cleaning residue in the system can help keep the desired slightly alkaline water pH of 8 to 9 Avoid a pH greater than 10 since this will adversely affect pump seal components c Aside stream filter is recommended see Fig 32 dur ing the cleaning process Filter side flow rate should be enough to filter the entire water volume every 3 to 4 hours Change filters as often as necessary during the cleaning process d Remove temporary bypass when cleaning is complete A suction guide with an internal strainer is standard on all 30XA units with factory installed hydronic packages This strainer allows removal of particulates from the chilled water loop Using the combination valve
