2. Ensure These Steps are Completed to Reduce
Chances of a Frozen Hydronic Coil
•
Ensure the air handler motor and control board are receiving
•
proper power input per the wiring diagram.
•
Ensure the hydronic coil has access to a constant water supply
as loss of water movement can lead to a frozen coil.
•
Prime the water circulator pump using the purge valve per the
•
"Start-Up" section of this installation guide.
•
Run the pump for five minutes after priming to ensure no air is
in the system.
•
If any interruption to the water supply occurs, prime the water
circulator pump again.
•
Insulate the water piping in unconditioned spaces or within
structures that may be unoccupied during freezing conditions.
•
If the air handler does not have an internal pump and/or relies
on an external boiler system for hot water, the installer may
need torewire the system to ensure that it maintains access to a
constant water supply.
