Installation

WARNING

Ground Wire!

All field-installed wiring must be completed by qualified personnel. All field-installed wiring must comply with NEC and applicable local codes. Failure to follow this instruction could result in death or serious injuries.

WARNING

Grounding Required!

Follow proper local and state electrical code on requirements for grounding. Failure to follow code could result in death or serious injury.

[ ] Install proper grounding wires to an earth ground.

[ ] Install an outside air thermostat in series with the flow switch to stop or prevent the unit from operating below the recommended ambient temperatures.
