Start-Up
58 WSHP-SVX13C-EN
Water Pressure Drop
Table 52, p. 58 and Table 53, p. 58 should be used to define
feet of head/pressure drop. Note that the feet of pressure
(ft/head) provided is at ARI/ISO standard.
To calculate feet of head, when using gauges that read in
PSIG, multiply PSI by 2.31.
Water Volume
Table 54, p. 58 and Table 55, p. 58 are provided for use in
calculating glycol requirements for the unit.
