OPERATION

1. Set Up - Connect unit to power source (120 Volts, AC,
60 cycle). Turn switch to on position (built-in pilot light
indicates when unit is operating). After a warm-up
period of 10 to 15 minutes, the heating and bending of
PVC conduit can begin.
2. Heating PVC - For best results, test for the best heating
time using a few pieces of scrap PVC. With all materials
at hand lower the door of the unit until it is fully open. Lay
first section of PVC between the pairs of guide rollers on
either end of the unit as shown in Fig. 3. The section of
PVC you wish to bend must be centered within the unit.
Keep door of unit closed during the heating process.
To obtain even heating of the PVC, conduit must be
constantly rotated by hand, as shown in Fig. 4. The
PVC should become pliable enough for bending after
about one minute. Heating time may vary due to differ-
ences in size and thickness of the PVC. An automatic
thermostat regulates temperature and prevents over-
heating of the unit.
3. Bending PVC - When PVC becomes pliable, lift open

door and remove from unit, laying the conduit on a flat,
clean surface. Bend can now be shaped by hand. To
set the bend, cool the PVC by using a rag or sponge
soaked with cool water, as shown in Fig. 5.
