The control lines for the drywall track and studs should be
laid out in the floor and ceiling (A) (see Figure 14).
Tracking may be installed now or after the unit is set.
Position the Ditto or Siamese Ditto fan coil assembly
between two rooms with the unit drywall separation spotted
over the wall control lines.
If not already installed, install the floor and ceiling tracks up
to and over the Ditto or Siamese Ditto Fan Coil unit.

The studs may be mechanically fastened to the Ditto or
Siamese Ditto Fan Coil. Care should be taken, however, not to
penetrate the supply or return water risers or internal piping.
Given the levelness of the floor and/or the fan coil assembly,
some shimming may be necessary.
Assemble the specified wall construction up to and over the
top of the fan coil unit (C) (see Figure 15).
With the fire-wall separation being complete, the drywall
skin on the surface of the individual fan coils can be applied.
Drywall can be applied directly to the surface, or, if necessary,
studding may be installed on the corners for vertical control
(D) (see Figure 15).
For ease of installation of the access panel, apply drywall on
the return air side directly to the surface of the unit (E) (see
Figure 15). When applying the wall board directly to the unit
cabinet, it may be necessary to shim the wall board in some
areas to achieve the desired finished wall surface.
After all drywalling and painting is complete, install
thermostats, supply air grilles and return air panels.
