When lling the system you will use a “Fill Entry Point” (A) and a “Fill Exit Point” (B), 5-10 gallon bucket, 3 washing machine hoses (F) (6 Ft), 1/2 Hp

“Transfer Pump” (D) and system uids.

When lling, purge 1-loop at a time with the rest of the remaining loops closed. Use propylene glycol (not ethylene glycol - car antifreeze). Make sure

“Purge Tee” (C) is in vertical position. Close “Air Eliminator” (E) when purging and pressurizing. When purging one loop (2-3 minutes) at a time observe

bubbles in bucket dissipating for removal of air. When all loops are purged free of air it is time to pressurize. With Transfer Pump (D) running, close off

“Fill Exit Point” (B) valve, pressure will now rise. When pressure gauge shows 18-24 PSI close off “Fill Entry Point” (A). System is now purged and

pressurized. For boiler operation rotate “Purge Tee” (C) to horizontal position and rotate “Air Eliminator”(E) stem cap srew CCW 1 turn.
