4. Slowly rotate conduit by hand until pliable.To test, lift one end of the
PVC conduit. Conduit is ready when it has a glossy appearance and
bends when lifted.

each 1/2” of PVC conduit diameter. ( Example: 2” PVC conduit will
heat in approximately 2 minutes.)
5. Open the heater door(s) using the handle and remove conduit from heater
and place on a clean, flat surface. Hand bend to desired angle.The bend
can be set by allowing to air cool or decrease this time by rubbing the
bend with a sponge soaked in cool water. NOTE: Be sure to keep all
liquids away from the PVC heater and turn unit off when not in use.
