SYMPTOM POSSIBLE CAUSE SOLUTION
NO HOT WATER • No Power• Safety thermal cut-off tripped• Not enough flow rate to activate unit• Plugged flow sensor
• Utility Controlling Load• Reset Thermal cut-off• Wrong size Pump• Activate thermostat• Clean flow sensor
WATER NOT HOT ENOUGH
• Water flow too high• Voltage too low• Glycol/water ratio to high• Manifold or Ball Valve Closed
• Reduce water flow rate• Supply correct voltage to unit• More than 20% less than 50%• Open Loops/Ball Valve
LEDS DO NOT LIGHT • Problem with electronic controls • Call Tech Support 763-331-3066
TROUBLE SHOOTING

FILLING THE SYSTEMOVERVIEW OF A TYPICAL SYSTEM
B
A
When filling the system you need a “Fill Entry Point” (A) and a “Fill Exit Point” (B), 10 gallon bucket, 3 wash machine hoses (F) (6 Ft), 1/2 Hp “Transfer Pump” (D) and system fluids.
When filling 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 position shown. 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 of “Fill Exit Point” (B) valve pressure will now rise. When pressure gauge shows 15-20 PSI close off “Fill Entry Point” (A). System is now purged in pressurized. For boiler operation rotate “Purge Tee” (C) to hoizontal position and rotate “Air Eliminator”(E) stem cap srew CCW 1 turn.
ITEM D: 1/2 HP Transfer Pump P/N: 4850C (763-331-3066)

Boiler Pressure Drops Table (Boilers SH3-12 thru SH3-29)
This table is used for sizing Primary (Boiler) Circulator
All boilers must use Primary/Secondary circuitry. This is used to create Hydraulic seperation between the Boiler and Emitter circulators allowing you to create different flow rates for each circuit.
