Walkerduct Pro Series Presets:

Use a Walker insert finder (Cat. No. 480) or other electronic locator to find
center of preset. Cut and remove carpeting or tile over preset. (Carpet may
be saved for later abandoning.) Chip out concrete exposing mudcap.

NOTE: If presets are more than 1/2" [12.1mm] below concrete, use of a hammer drill

with 1/2" chisel is recommended. BE CAREFUL NOT TO DAMAGE PRESET!

Remove Mudcap: (See Figure 1).

A. Strike blade of screwdriver or 1/4" [6.4mm] cold chisel along side of

mudcap as shown. Top edge of mudcap will deflect inward.

B. Pry out cap with screwdriver by positioning blade between preset wall

and deflected edge of mudcap or, use pliers to grab edge of cap and lift
out. Remove all debris from preset.

C. Grout around opening if concrete does not break away cleanly.

Remove Knockout: (See Figure 2).

A. Insert a wire hook into arched opening at center of preset. This will

prevent knockout from falling into the raceway.

B. Insert screwdriver blade into opening in base of preset. Push

screwdriver toward center of preset, breaking tabs. Position screwdriver
into opening on other side of knockout and break tabs to release
knockout. Remove all debris from raceway.

CAUTION: Some sharp edges may occur along knockout tabs.

These must be deburred.

IMPORTANT! Tighten bonding screw in base of preset with

No. 3 Phillips screwdriver.
