OPERATING INSTRUCTIONS —453 PVC Heater
1. Place PVC conduit heater on a flat, dry surface. Plug heater into a grounded
power source.Turn switch to ON position. Rollers will begin to rotate.
2. Put on insulated gloves.
3. After warm-up period, ( approximately 7 min. ) place conduit on rollers
inside the heater. Using the handle, close the door(s) over the section
of PVC to be heated.
4. To test, lift one end of the PVC conduit. Conduit is ready when it has
a glossy appearance and bends when lifted.
NOTE: PVC conduit MUST be rotated to provide even heating and
to prevent scorching.
NOTE: PVC conduit will take approximately 30 seconds to heat for
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.
PVC CONDUIT HEATER ACCESSORIES
•To prevent flattening and crimping during the bending process, CurrentTools
plug sets are recommended for 2”and larger PVC conduit.
•CurrentTools Model #454 PVC support stand is recommended to prevent
sagging of the conduit during the heating process.
