1) Your TC110 Series system operates with hot water under pressure. To reduce the risk of
scalding:
Always wear work gloves and safety glasses when operating the unit.
Never operate the unit with panels or shields removed.
Pipe the relief valve to an open drain.
Never install a fitting or hose that is rated less than 150 psig and 250
F (1034 kPa/10.3
bar and 121°C).
2) To reduce the risk of electrical shock:
All electrical installation and repairs should be done by a qualified electrician.
Ground the unit in accordance with electrical codes.
Never attempt any repairs without first opening and locking out the main disconnect.
Never deactivate or neutralize any safety device.

Sequence of Operation
The simplicity of design and the highly engineered controller make this unit almost self-
operating. The ON/OFF and VENT switches and the temperature controller buttons are all
that is required to operate this unit.
After you complete all connections, turn the water supply ON, then turn control power ON.
The unit automatically vents for a preset time of one (1) minute. If you need additional vent
time, press the VENT button on the control panel.
As the water comes in the water supply line, the water must enter the pump, up through
the tank and out through the TO PROCESS line, through the process, back through the
FROM PROCESS line, and through the solenoid line and out the drain line.
At this time, watching the drain for bubbles or erratic flow will indicate whether or not the
system has been properly vented. If a steady stream flows from the drain line, it is certain
that all the air is out of the system.
TCU systems provide temperature control on processes by directly heating
the process water and injecting cooling water into the process water.
When the unit is energized, the pump starts and a one-minute vent
sequence opens the cooling/vent valve to remove any air trapped in the
process piping.
