Step 3: Prepare the Venting Blower

Your microwave oven is shipped with the blower assembled for room venting. You need to adjust the blower if you want wall-venting or roof-venting installation.

Warning
  • Electric shock hazard! Unplug unit before working on it.

  • Do not pull or stretch the blower wiring. Pulling and stretching the blower wiring could result in electric shock.

  • To avoid risk of property damage, unplug the microwave oven or disconnect the power at the source by removing the fuse or throwing the circuit breaker.

  • To avoid risk of personal injury, wear protective gloves when handling the mounting plate.

Installation

  • Remove any shipping materials and parts from inside the microwave oven. Set them aside for later use.

  • Cover the countertop or cooktop with a thick, protective covering to protect it from damage and dirt.

    1. Blanket, cardboard or other covering

    Note
    • If you have a free-standing range, disconnect it, move it onto a piece of cardboard or hardboard and pull it away from the wall, so that you can get closer to the upper cabinet and back wall for easier measuring and drilling.

  • Locate the exhaust adapter, grease filters and hardware packet.

  • At this point, remove any adhesive tape (if there is any), on the exhaust adapter, the grease filters and the power supply cord.

Room-Venting (Recirculating) Installation

This oven is shipped assembled for room-venting.

Wall-Venting Installation

  • Remove one or several blower plate mounting screw(s) a and one or two blower unit mounting screw(s) f. Remove the blower plate d from the cabinet.

    b Blower unit

    c Knockouts

    e Back plate

  • Carefully lift the blower unit out of the microwave oven.

  • Use side cutters or tin snips to cut out and remove the knockouts b from the back plate a. Be careful not to distort the back plate. Discard the knockouts.

  • To avoid pinching the blower wire, make sure that it is channeled underneath and between the two exhaust ports when they are rotated.

  • Rotate and reinstall the blower unit a so that the exhaust ports b face the rear of the cabinet and are aligned with the rear knockouts. When you insert the blower unit, the blower wire c must be routed as shown.

  • Attach the blower plate d to the microwave oven so the blower unit exhaust ports c and blower plate opening are aligned. Attach one or two blower unit mounting screw(s) f and then one or several blower plate mounting screw(s) a.

    b Blower unit

    e Back plate

  • Insert the tabs on each side of the damper into the holes at the inside rear of the adapter. Attach the exhaust adapter a to the back plate wall side. Push in securely until it is past the top locking tabs c and in the lower locking tabs c. Make sure that the damper hinge is at the top and that the damper swings freely.

    b Damper (hinge side up)

    d Guides on back plate

    e Slide exhaust adapter into guides on back plate.

Roof-Venting Installation

  • Follow steps 1 and 2 under Wall-Venting Installation.

  • Rotate and reinstall the blower unit a so that the exhaust ports b face the top of the cabinet. When you insert the blower unit, the blower wire c must be routed as shown.

  • Attach blower plate d to microwave oven. Attach the one or two blower unit mounting screw(s) f and then the one or several blower plate mounting screw(s) a.

    b Blower unit

    c Knockouts

    e Back plate

  • Insert the tabs on each side of the damper into the holes at the inside rear of the adapter. Attach the exhaust adapter a to the blower plate b with the two tapping screws provided. Make sure that the damper c swings freely.

Warning
  • Fire hazard! Correctly install the vent fan before use.

When changing the vent fan position for wall venting or roof venting:

  • Properly align the ventilation fan openings and blower plate knockouts.

  • Ventilation fan openings should be completely exposed to the outside.

  • After installation, check the air ventilation path. Refer to step 2 for proper vent selection.

Improper installation can cause problems such as:

  • Inability to assemble the blower plate or ventilation motor correctly

  • Abnormal noise during product operation

  • Weak ventilation

  • Product overheating and the possibility of product breakdown or fire
