Step 6

Electrical

The Bosch dryer comes with 4-wire power supply cord pre-installed. This cord fits a 4-wire receptacle as shown in the upper section of Figure 11.

If your receptacle is a 3-wire receptacle, as shown in the lower section of Figure 1, a 3-wire ``Dryer Cord'' must be purchased locally. The 4-wire cord must then be removed and the 3-wire cord installed in its place.

Electrical Connection, 4-Wire

For a 4-wire system, all that is necessary is to plug the 4-wire power supply cord into the 4-wire receptacle of the proper rating.

Note: The receptacle should be located so that the plug and receptacle will be accessible when the dryer is in its final installed position.

Electrical Connection, 3-Wire

If your receptacle is a 3-wire receptacle as shown below, Figure 19, you must obtain a 3-wire dryer cord. Dryer cord can usually be found at your local hardware supply, electrical supply or home center. Cord should have closed loop or upturned end wire terminating connectors.

Note: If the dryer is installed in a mobile home or in areas where local codes do not permit grounding, only a 4-wire power supply cord shall be used.

To Change Cord:

1.Make sure that the dryer is not plugged into any power outlet.

￿WARNING

DO NOT plug end of dryer power cord into a live receptacle before connecting dryer power cord to dryer terminals and closing junction/splitter box as described below.

DO NOT reuse old power supply cord.

Power cord must be changed only by a qualified person.

2.Remove the screw from the cover of the junction/splitter box located at the top rear of the dryer.

3.Remove the green ground wire from the ground terminal.

4.Remove the red, white and black wire from the terminal block.

5.Loosen the 2 screws in the U.L. strain relief clamp, holding the 4-wire cable.

6.Thread the 4-wire cable out through the U.L. strain relief clamp and throw away.

7.Thread the new 3-wire dryer cord through the U.L. strain relief clamp.

8.Attach the power cord Ground conductor (the center wire) to the Ground terminal. Tighten the terminal so that it securely holds the Ground conductor.

9.Attach the two remaining power cord outer conductors to the 2 terminals labeled L. Tighten both screws so that the power conductors are securely held in place. See Figure 20.

10.Tighten the screws on the U.L. strain relief so that the power cord cannot be moved.
