Removing a window :
1. Remove a reveal molding, if applicable. Some windows have encapsulated moldings that cannot be removed. Encap-
sulated windows can also be removed without damage since the GYSDUCTION AUTO only heats metal. Some windows
have metal moldings, which need to be removed prior to applying heat with the device. The GYSDUCTION AUTO will
heat the metal nearest to the Glass inductor or other heating heads. If the metal trim cannot be removed, it will be
necessary to heat the pinch weld from inside the vehicle.
2. Although not always necessary, it is recommended that the interior trim to be removed from the vehicle to minimize
the possibility of burning the trim. Removal of the interior trim also exposes any additional hardware such as clips and
studs that may be holding the window in place. Such hardware will need to be released prior to the removal process.
Locating the position of the urethane bead is also easier with the interior trim removed.
3. Disconnect antennas and defroster grids.
4. To prevent scratches to the painted surface that could be caused by wooden or plastic wedges, place a layer of mas-
king tape around the painted surface as close as possible to the glass or molding.
5. Place a clean layer of masking tape over the pole pieces of the Glass inductor to prevent scratching the glass as the
Glass inductor is moved back and forward over the glass. Replace the masking tape for every new glass to be removed.
6. Clean the glass thoroughly before starting the removal process.
7. Always start the removal process near the area of the vehicle where the repair is to be made. The greatest risk of
paint damage by the wedges is at the starting point of the glass removal due to the difficulty of getting the first wedge
in place. It's better to start from a corner if possible and progress around the window towards the undamaged area of
the vehicle.
8. Ideally the Glass inductor should be placed directly on top of the urethane for better window removal. However, some
vehicles have narrow pinch welds that cause the Glass inductor to be too close to the painted surface, putting unneces-
sary heat into the area possibly burning the paint. In some case a damp towel or heat sink compound may need to be
applied to absorb the heat being put into the painted surface (see illustrations). If possible, keep the heating attachment
at least 1 inch away from the edge of the painted surface.
9. Generally the urethane is located at the inner edged of the pinch weld. To locate the pinch weld, place the Glass
inductor on inner side of window about 4" away, parallel to the edge or flange of window opening.
10. As previously stated it is better to start from a corner on the same side of the vehicle where the repair will be carried
out. Start by moving the heating attachment back and forward for about 12 inches on each side of the corner at a rate
of about ½ inch per second. Heating too much an area is ineffective because it reduces the amount of heat produced
in the pinch weld. Make about 4 passes over the corner. A light trail of vapor/smoke should be visible by this time.
Heavy smoke is not good, stop the process and inspect the vehicle to determine the cause of smoke. Do not breathe
the vapors. An external air supply respirator is recommended. Hydrogen Cyanide gas is emitted from the hot urethane,
which can be poisonous.
11. Once the vapor is visible, you are at the optimal temperature for the urethane to release. Gentle outward pressure
is required to break the bond. It is possible for it to take several minutes to break the initial bond of the urethane. Once
the bond is broken, the urethane will not re-bond with the metal. A suction cup can be used in the corner for pulling
the glass as the pinch weld is heated. Once the corner is lifted, a plastic wedge, such as the GYSDUCTION AUTO glass
wedges can be inserted behind the glass. The wedges provide outward force while heating, allowing glass removal to
be performed by one person. Do not put too much pressure on the glass, or it will break. Front glass is laminated and
is easily cracked. Side and rear glasses are tempered and much more durable. Start with rear or side glass first then
progress to windshields as you gain experience. It's better to practice on salvage vehicles first to get familiar with the
techniques.
12. Add wedges or reposition other wedges as you move around the glass. Tempered glass can withstand pressure
without breaking. If pressure, it is better to do it away from the car to prevent unnecessary paint damage that could
occur if pressure is applied to the paint with the wedge. Constant outward pressure is necessary to enable the window
to release at the lowest possible temperature. See illustrations and notes on the next pages for additional information.
13. Typical removal time for small quarter glass is around 10 to 15 minutes. Typical removal time for rear glass and SUV
side glass is around 10 to 20 minutes. Front Glass can be removed in as little at 15 minutes, but some larger vehicles
require up to an hour to remove front glass.
Inductor consumables :
The bolt and glass inductors are covered with a fiber glass cloth protection, in order to apply them directly against the
parts to be heated. This cloth protection is a consumable which will wear and damage with use. These can be replaced,
and GYS sells kits to allow users to perform this replacement.
