OPERATING INSTRUCTIONS — 452 PVC Heater
1. Place PVC conduit heater on a flat, dry surface. Plug heater into a grounded
power source. Turn switch to ON position.
2. Put on insulated gloves.
3. After warm-up period, ( approximately 7 min. ) place conduit on rollers
inside the heater. Using handle, close door(s) over the section of PVC
conduit to be heated.
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.
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.
