| | 1) MISSING CORRECT TDH.SUBMIT TOTAL DYNAMIC HEAD |
| | CALCULATIONS FOR THE MAXIMUM SYSTEM FLOW. THE MAXIMUM |
| | FLOW OF THE PUMP FROM ITS PUMP CURVE AND THE SIMPLIFIED |
| | TOTAL DYNAMIC HEAD CALCULATION IS NO LONGER ALLOWED TO |
| | BE USED IN DETERMINING MAXIMUM SYSTEM FLOW RATE PER |
| | ANSI/APSP/ICC 7 - 2013 SECS. 4.4.9, 4.4.9.1. THE 2013 |
| | EDITION ADDRESSES FLOW RATE IN GALLONS PER MINUTE |
| | (GPM). IT REQUIRES THAT MAXIMUM SYSTEM FLOW RATE DOES |
| | NOT EXCEED THE LISTED MAXIMUM FLOW RATE OF THE SUCTION |
| | OUTLET FITTING ASSEMBLY (DRAIN COVER).THE TDH |
| | CALCULATIONS MUST INCLUDE ALL OF THE SYSTEM COMPONENTS |
| | INCLUDING SUCTION AND RETURN PIPING, FITTINGS, VALVES, |
| | HEATER, FILTER, AND CHLORINATOR. ALL SYSTEM COMPONENTS |
| | EXCEPT THE PUMP. |
| | |
| | SUBMIT TWO LEGIBLE COPIES OF THE POOL PUMP CURVE. |
| | IDENTIFY ON THE PUMP CURVE WHICH CURVE KEY IS SPECIFIC |
| | TO THE PUMP BEING INSTALLED ON THIS POOL. THIS IS |
| | NEEDED TO CONFIRM THE MAXIMUM SYSTEM FLOW FROM THE TDH |
| | CALCULATIONS. ANSI/APSP/ICC 7 - 2013 SECS. 4.4.9, |
| | 4.4.9.1 |
| | |
| | THE SUBMITTED TDH CALCULATIONS DO NOT APPEAR TO SHOW |
| | THE FRICTION LOSS THROUGH ALL THE SYSTEM COMPONENTS. |
| | THE CALCULATOR SHOWS THE PIPE, FITTINGS, VALVES, |
| | HEATER, FILTER, ETC. BUT THERE IS NO FRICTION LOSS |
| | ASSOCIATED WITH THESE ITEMS. CLARIFY. |
| | |
| | INDICATE ON THE PUMP CURVE WHICH CURVE KEY IS FOR THE |
| | PUMP BEING INSTALLED ON THIS SYSTEM. WPB AMEND. TO FBC |
| | SEC. 107.2.1. |
