CERTIFICATE OF INSTALLATION-USER INSTRUCTIONS CF2R-PLB-03-E Pool And Spa Heating Systems (Page 1 of 2) MR-PLB-03-E User Instructions A.POOL AN D SPA SYSTEM TYPE Pick from Pool only,Spa only,or Pool and Spa B.SYSTEMS AND EQUIPMENT(SECTION 114.0(A)) Before any pool or spa heating system or equipment may be installed,the manufacturer must certify to the Energy Commission that the system or equipment complies with§110.4 and§110.5.The requirements include minimum heating efficiency according to Appliance Efficiency Regulations,an on-off switch outside the heater,permanent and weatherproof operating instructions, no continuous pilot light,and no electric resistance heating C.INSTALLATION(SECTION 114.0(8)) A time switch or similar control mechanism must be installed as part of the pool water circulation control system thatwill allow all pumps to be set or programmed to run only during the off-peak electric demand period and for the minimum time necessary to maintain the water in the condition required by applicable public health standards D.PUMP SIZING AND FLOW RATE SPECIFICATION(SECTION 150.0(P)) The pool filtration flow rate may not be greater than the rate needed to turn over the pool water volume in 6 hours or 36 gpm, whichever is greater.Calculate Max Flow Rate using the following equation: Max Flow Rate(gpm)=Pool Volume(gallons) 360min. Pool piping must be sized according to the maximum flow rate needed for all auxiliary loads.Show work to calculate return and suction line flow rate,minimum filter area,and the maximum pump flow rate correspond to the pool volume in accordance to section 1S0.0(p),or refer to Table C below for the prescriptive values.The maximum velocity allowed is 8 fps in the return line and 6 fps in the suction line,and the maximum pump flow rate is less than 6 hour filtration turnover. 03 Select whether the alternative calculation is used. 06 Enter the Pool volume 07 Enter the Return Pipe Diameter(inches). 09 Enter Suction Pipe Diameter(inches). 10 Enter Filter Type(Cartridge,Sand,DE). 11 Enter Filter Surface Area(ft ). 12 Enter the Max Pump Flow Rate(gpm). 13 Enter the measure flow rate of the return line in feet per second.This is only used if the alternative calculation is used. 14 Enter the measure flow rate of the return line in feet per second.This is only used if the alternative calculation is used. 15 Verify that an alternative compliance calculation or flow test result is provided for this pool or spa use(D.03=Yes),and verify whether D. 13 is less than or equal to D.08,and D. 14 is less than or equal to D.06. Indicate Yes or No. If no, project fails prescriptive compliance. E.SYSTEM PIPING There must be a length of straight pipe that is greater than or equal to at least 4 inches pipe diameters installed before the pump. Refer to Table D below for the required pipe length.Traditional hard 90°elbows are not allowed.All elbows must be sweep elbows or a type of elbow that has a pressure drop less than the pressure drop of straight pipe with a length of 30 pipe diameters. F.FILTRATION EQUIPMENT Backwash valves must be sized to the diameter of the return pipe or two inches,whichever is greater. Multiport backwash valves have a high pressure drop and are discouraged.
