IMPORTANT SAFETY INSTRUCTIONS
Do not use this heater in a hazard-
ous environment. Hazards include
flammable liquids, gases, or other
materials. Using this heater in a
hazardous environment can result
in a fire or explosion.
Failure to observe this warning will
result in severe injury or death.
Electric Shock Hazard. Do not
expose heater to rain or moisture.
Failure to observe this warning can
cause severe injury or death.
Heater temperature will exceed
538°C (1000°F).
• Wear insulated gloves when using
this heater and when bending
PVC.
• Do not leave heater unattended.
• Unplug when not in use.
Failure to observe these warnings
can result in severe burns.
Use in a well-ventilated area. Hot
PVC will give off fumes. Failure to
observe this warning or precaution
can result in serious injury or death.
• Inspect tool before operating. Replace any worn,
damaged or missing components with Greenlee
replacement parts.
• Use this heater for manufacturer’s intended
purpose only. Do not use as a space heater. Use
other than that which is described in this manual
can result in injury or property damage.
If using an extension cord, use one with the
following characteristics:
• 14 AWG minimum
• 45 meters (150') maximum
Using a lighter gauge or longer cord will cause a
loss of heating power.

• Do not modify the plug provided
with the tool.
• Connect this tool to a grounded
receptacle.
Failure to observe these warnings
can result in severe injury or death.
This tool must be grounded. In the event of a malfunc-
tion or breakdown, an electrical ground provides a path
of least resistance for the electric current. This path of
least resistance is intended to reduce the risk of electric
shock.
This tool’s electric cord has a grounding conductor and
a grounding plug as shown. Do not modify the plug.
Connect the plug to a corresponding receptacle that is
properly installed and grounded in accordance with all
national and local codes and ordinances. Do not use an
adapter.

Operation
See the Exploded View. Remove the handles from the
inside of the PVC heater and attach them to the covers.
When bending 2" or larger conduit, Greenlee recom-
mends using 859-series PVC plugs. Install one plug in
each end of the conduit and tighten the wing nut until
the conduit is sealed. Remove the plugs after the PVC
has cooled.
1. Place the heater on a firm, flat surface.
2. Plug the cord in. Turn the heater ON. The pilot light
will illuminate. Preheat the unit by setting the timer
for eight minutes.
Notes:
•On the 848, the rollers will begin to rotate.
•The timer will not turn the heater OFF.
3. After preheating the PVC heater, refer to the chart
on the rear of the heater for the approximate conduit
heating time. Set the timer.
4. Place the conduit on the rollers and close the cover
over the section of conduit to be bent. Leave the
cover open over any section that is to remain
straight. This will prevent heating and deforming the
straight section.
Note: If using model 847, rotate the conduit by
hand.
5. After the timer rings, check the PVC by lifting it at
one end. When the PVC is flexible, open the covers
and remove the conduit.
6. Place the PVC on a flat surface. Form the bend by
hand. Allow the PVC to cool or set the bend by
applying cool water with a sponge or rag.

Troubleshooting
PROBABLE CAUSE
PROBLEM PROBABLE REMEDY
Heater does not heat up. No power at supply circuit. Check power supply with a voltmeter.
Verify that the circuit has the
appropriate voltage and current
rating. See the Specifications section
of this manual.
Switch is faulty. Disconnect power. Turn the power
switch to the ON position. Check
continuity between:
•terminals 1 and 2
•terminals 3 and 4
Replace the switch if either terminal
pair does not have continuity.
Heating element is faulty. Disconnect power. Disconnect
terminals A and B. Check continuity
between terminals A and B. Replace
the heating element if this terminal
pair does not have continuity.
Pilot light does not light up. Pilot light is faulty. Disconnect power. Check continuity
between terminals 5 and 6. Replace
pilot light if this terminal pair does not
have continuity.
Motor does not operate. Motor is faulty. Disconnect power. Check continuity
between terminals 7 and 8. Replace
motor if this terminal pair does not
have continuity.
