Location of EXTroL® Expansion Tanks do NoT LoCATE THIS ProdUCT WHErE LEAKING or FLoodING CoULd CAUSE dAMAGE To THE SUrroUNdING ProPErTY. The AMTROL® expansion tank may be placed in any convenient position within the mechanical room (or building). If multiple tanks are installed, they should all be on the same level. Point of Connection Unlike a conventional tank, the EXTROL® sealed air cushion does not require replenishment so DO NOT connect to an air separator or other air collection device. As with any expansion tank, it is recommended that the EXTROL® be connected to the suction side of the pump. This will prevent the pump head from becoming subtractive which may result in entry of air and vapor formation at high points in the system. By connecting the EXTROL® on the boiler return, displacement of coolest system water into tank is ensured reducing energy waste. Low pressure drop components such as air separators and boilers may be placed between point of connection and pump suction if desired. System design will dictate the feasibility of this. Natural convection losses and the entry of air into tanks are eliminated by connection to the side or underside of main pipe. The piping should be pitched up and away from the EXTROL® to eliminate any potential air traps. Installation THIS ProdUCT MUST BE INSTALLEd BY A QUALIFIEd ProFESSIoNAL. 1. Note location of system connection, air charge valve and drain connection on tank. 2. Remove the plug or pipe cap from the system connection. 3. Remove the 1 1/2” NPT plug covering the air charge valve. 4. Before making any connection to the tank, check the tank and air charge (use an accurate pressure gauge). The air pressure must be equal to the minimum system pressure at the tank location. 5. After making sure the air charge is correct, replace the 1 1/2” plug over the air valve. 6. The EXTROL® may now be piped to the system (use the suggested EXTROL® piping diagrams on the next page). 7. Using the table below, select appropriate pipe size. Connection to each EXTROL® must have a lock shield gate valve and union to allow isolation and removal if required. Make up and fill valves, whether manual or automatic, should be tied into the connecting line. This will ensure that pump operation will not affect valve operation. operational Limits Maximum Operating Pressure: As stamped on ...
