Installation
Do not exceed the electrical and temperature ratings printed
on the dataplate of the furnace.
CAUTION!
Improper operation of the furnace
could result in dangerous conditions. To preclude
hazard and minimize risk, follow all instructions and
operate within design limits noted on the dataplate.
4.1 Location
Install the furnace in a level area free from vibration with a
minimum of three inches of space, for air flow, around the unit.
4.2 Wiring
For detailed wiring information, refer to Figure 7 on page 21.
4.2.1 120 VAC Operation
The TF55030A model operates on 120 VAC, 50/60Hz, single
phase. Each furnace includes a 120 VAC grounded plug and cord
set. The units are completely prewired and ready for operation.
Before initial start up, inspect the furnace's wiring connections:
1. Remove the corner screws on the back panel of the furnace
and detach the back panel.
2. Check that the thermocouple is securely mounted and
undamaged.
3. Check the thermocouple wiring connections. Refer to
Figure I. Red is always negative.
CAUTION!
Failure to check thermocouple
wiring connections before initial start up could
result in damage to the furnace.
4. Check that all electrical connections are secure.

5. Replace the back panel on the furnace and secure with the
corner screws.
6. Plug the line cord into a 120 VAC, 15 amp, grounded line. The
furnace draws approximately 6.7 amps at 120 VAC.
4.2.2 208 VAC Operation
The TF55030C model operates on 240 VAC, 50/60Hz, single
phase. The Lindberg/Blue M Moldatherm tube furnace heating
elements are specifically designed for operation on 120, 208,
or 240 VAC. A furnace wired for 240 VAC operation can also
operate on 208 VAC. However, heatup and recovery times will
be longer.
