Step 1 Determine box location and conduit layout. Remove knockouts and attach proper
conduit adapters (not included) to steel base.
Step 2 Select internal compartments of box which are to be used for power. Service
isolation may be acquired by plastic housing. Power compartments must be
arranged adjacent to one another to utilize the “pass-around” tunneling system (see
Figure 1).
Step 3 Slip housing over base. Insert retaining bracket inside housing and secure to base
using four #10-24 x 3/16" [4.8mm] screws provided (see Figure 2).
Step 4 Adjust box so that top of housing is 1/16" [1.6mm] below screed line using the
leveling screws provided. Secure box to subfloor using wire or nails through the
slots adjacent to the adjusting screws. Once positioned, connect conduit to fittings.
Step 5 Leave receptacle brackets in plastic bags until concrete is set and receptacles are
ready to be installed. Place brackets in box and insert mudcap.
NOTE: Make sure proper compartments are isolated before concrete
placement as barriers must be broken out rendering the barrier
useless and possibly breaking the plastic housing.
RFB4-SS Shallow Steel Recessed Floor Box – Before Concrete Pour:
Step 6 Locate box and chip away concrete located in mudcap. Remove mudcap and
device plates from the box. Clean out any debris.
Step 7 Wire devices (not included) in accordance with the National Electrical Code or any
local code that applies. Make sure that any ground leads are connected to ground
screws. Connect receptacles to receptacle brackets using #6-32 x 3/8" [9.5mm]
screws (see Figure 2).Attach the receptacle to the receptacle mounting bracket with
two additional screws and nuts (not provided). Secure receptacle brackets to base
using remaining #10-24 x 3/16" [4.8mm] screws.
Step 8 Complete procedure by installing a FloorPort Series Activation (sold separately)
using the installation instructions provided with the unit.
This box and activation are UL Listed for use with tile, terrazzo, and carpet
floors.
WARNING: If concrete does not break clearly around preset, the
activation might not be properly supported. If edges of
FloorPort Activations are not supported by concrete on all
sides, repair of excessive concrete spalling is required.
