Electrical
Check the nameplate on the unit for required voltage and amperage before making any electrical
connections.
!! DANGER!!
IMPROPER ELECTRICAL POWER CONNECTIONS
CAN DAMAGE THE UNIT AND CAUSE
SERIOUS OPERATOR INJURY OR DEATH!
Make all electrical power connections in the front of the unit. You can run
power to the supply terminals from either side of the unit. Make sure that all
three phases are wired correctly. If not wired properly, the pump may run
backwards, possibly damaging the unit.
Caution I
Again, check the nameplate on the unit for
correct voltage and amperage.

Unit Startup
A highly engineered controller and controls make this unit almost self-operating. Before you
begin heating, you must perform the following startup procedures. By doing so, you ensure that
all air is vented from the system to prevent fluid degradation and damage to the heater.
Note: AEC, Inc. recommends that you flush your TDH unit before you perform these
procedures. See flushing instructions included with AEC TrueFlush™ flushing fluid for
more information.
Caution I
Ensure that the reservoir tank vent port is not plugged.
The reservoir tank must never be pressurized.
1. Add fluid to the reservoir tank until the level is near the top of the sight glass.
