10.10 Conduit There are two (2) options that can replace the standard PVC conduit option: • The PVC Coated Pipe Conduit option utilizes Rob Roy PVC coated conduit and provides a cost-effective hybrid solution where a UL listed PVC coating covers rigid steel tubing. This option has the following specifications: • Rigid Conduit: PVC coated steel • Flexible Conduit and Fittings: UL listed PVC coated steel with stainless steel fittings • The Stainless Steel Conduit option provides superior corrosion resistance and protection for all electrical system routings. This option has the following specifications: • Rigid Conduit: SCH 40 stainless steel • Flexible Conduit and Fittings: UL listed PVC coated steel with stainless steel fittings 10.11 Water Addition The standard system comes with two (2) water addition ports, allowing for a customer to install connections for up to two (2) separate water connections based on the connection size and type listed in Table 2: Utility Requirements . The Dual Water Ports with one (1) or two (2) Pneumatic Valve(s) option adds a pneumatically controlled angle-seat valve to the water inlet port (quantity based on option selection). This option will provide a hygienic valving solution and will change the connection size / type listed in Table 2: Utility Requirements to 1.5" FNPT (quantity based on option selection). 10.12 Chemical Addition The standard system comes with three (3) chemical ports, allowing for a customer to install connections for up to three (3) separate chemical injections based on the connection size and type listed in Table 2: Utility Requirements . The Triple Chemical Ports with one (1), two (2), or three (3) Chemical Blocking Valve(s) option adds a check valve and a pneumatically controlled diaphragm valve to a chemical injection port (quantity based on option selection). The check valve inlet is remotely mounted on the side of the cabinet and will change the connection size / type listed in Table 2: Utility Requirements to 0.5" Tube (quantity based on option selection). This option provides both a hygienic valving solution and ensures a greater level of safety by providing zero leakage. 10.13 Chemical Flow Metering The Chemical Flow Metering Assembly option adds paddle wheel style flow meter(s) to a chemical injection port (quantity and flowrate based on option selection). This option provides feedback quantifying the amount of chemical used and adds system monitoring and alarming capabilities. This option may be required if the chemicals being used are non-conductive or are difficult to measure using conductivity sensors. To accommodate different chemical injection rates there are two (2) different types of flow meters, low and high flow. The respective flowrate ranges for each type are listed in below in Table 11: Flow Meter Data .
NOTE • The “Low Flow” flow meter should be selected when using accessory 12.2.3 Chemical Pump Assembly – Electronic Metering Pump or 12.2.5 Chemical Delivery Skid – Electronic Metering Pump. • The “High Flow” flow meter should be selected when using accessory 12.2.2 Chemical Pump Assembly – Diaphragm Pump or 12.2.4 Chemical Delivery Skid – Diaphragm Pump.
