Fan Does Not Start
If the fan does not have power:
•
Check that the correct power supply is connected to the Maxcoil.
•
Check the condition of the power connection cable.
If the fan has power, but is not running (all switches in the appropriate position and connections
are made):
•
The fan motor is equipped with a thermal overload fuse that may tripped in cases of extreme
temperature. The fuse is located inside the fan motor and must be reset if tripped.
Fan is Running but No Heat
If the fluid inlet is cold:
•
Check that all valves are open and fluid is circulating. If the valves are open and there is
circulation but the fluid is cold, the problem lies with the water heater.
If the fluid inlet is hot but the outlet is cold and still no heat:
•
Check the heat exchanger coil for flow obstructions. If flow is obstructed, disconnect the unit
from the circulation system and flush.
HTF is Leaking
•
Check all connections, fittings, and hoses. Tighten as required.
•
Shut down the fan and check the coil for leaks. Replace coil if leaks are found.
