T.P.I. (Top Performer Immersion)
Installation Manual
Installation
Attaching TPI to Top Performer tank:
Place hole in back of TPI over immersion well. (See Diagram 1)
TPI should fit flush against the tank without immersion well protruding beyond bottom of TPI case.
Use self-tapping screw provided (Screw A) to attach TPI directly to the Top Performer.
Attaching TPI to other tanks:
Place hole in back of TPI over immersion well. (See Diagram 1)
If TPI cannot fit flush against the tank without immersion well protruding beyond bottom of TPI case, TPI can
be mounted directly onto the immersion well itself.
Place square nut in the retaining well on the TPI box.
Use proper machine screw provided (Screw B or Screw C) to tighten against the immersion well.
Inserting the Temperature Sensor:
Slide temperature sensor all the way into the immersion well
– until it contacts the end. (See Diagram 1)
The sensor will measure temperature adequately by resting against the bottom of the immersion well.
(Note: Sensor does NOT need to make intimate contact with entire well surface to work properly)
The sensor is wired to the thermistor wire connector button on the TPI. To remove or install, See Diagram 4.
Wiring the TPI
THE TPI MUST BE POWERED WITH 24VAC.
Run all 24VAC wiring thru the square notch on bottom of TPI case. (See Diagram 2)
Connect incoming wiring to 24VAC connectors on the bottom right corner of TPI. (See Diagram 2)
Connect outgoing wiring to PUMP/TT connectors on the bottom left corner of TPI. (See Diagram 2)
If output wiring is 110VAC, use knockout at bottom of TPI case, with appropriate chase nipple.
Consult attached Wiring Diagrams for appropriate wiring configurations.
TPI Cover:
Be certain to replace TPI cover using Black Screw provided.
Operation
Indicator Light operation:
The TPI has an integral indicator light at the top of the case. (See Diagram 3)
Indicator light will come on (Green) when TPI is powered.
When TPI is calling for heat, the Indicator light will blink.
When TPI is satisfied, the Indicator light will be solid.
During normal operation, Indicator light is Green.
If the thermostat detects no probe, the Indicator LED will flash Red. Ensure connections are tight.
