WARNING
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 to
rewire the system to ensure that it maintains access to a constant
water supply.
