•When installed in areas where freezing tempera- tures can be encountered, drain the water circuit to prevent possible freeze-up damage. See the Freeze Protection Section.

Refer to the unit rating plate below the control panel for precise power requirements for your unit, and for ampacity and over-current protection requirements.

•Locate the equipment disconnect means within 3 feet (90cm) of the heater’s electrical enclosure, or as close to the heater as possible. Always satisfy applicable codes and standards.

•In sizing power wiring, be especially aware of up- sizing requirements necessary due to wiring distances. Always satisfy applicable codes and standards.

•Electrical installation should be done by a licensed electrician only.

This unit is pre-wired to work with external control sys- tems, heat-on-demand options and other external time clock overrides. Refer to the external control system’s instructions, and page 19 of this manual, for installa- tion information.
