Section 6, Wiring the Electrical System
6-4 POLAR™ HD Heating Module
6.6 Distribution Module Zone Control
Board (optional)
• The Distribution Module is controlled by a separate Zone Control
Board. See Section 9, Installing the Distribution Module.
6.7 What NOT to Do
Never shut off the POLAR™ HD Heating Module power via an inline
battery or master switch while the system is running. Never
disconnect the battery when the POLAR™ HD Heating Module is
running, and never disconnect the battery while the inverter is
charging. Do not wire the POLAR™ HD Heating Module through a
disconnect that is used as a normal shut-down of the DC system.
Doing either will severely damage the POLAR™ HD Heating Module
because it fails to automatically purge the combustion chamber.
Such damage is detectable upon inspection and will not be covered
under warranty. Always shut the system off using the normal
system controls, after it has completed its purge and cooled down
the combustion chamber.
