Demolition, Step-by-Step Guide
Recommended Supplies: drop cloths, plastic sheet
coverings, utility knife/hole saw, shears/nibbler/
reciprocating saw, small rotary pipecutter, brazing torch,
pipe wrenches, straight edge-level, hammer, screw gun,
chisel/pry bar and a pencil.
NOTE: Jobsites will vary greatly. The general
demolition procedures listed here are
intended as a recommendation only. A
thorough evaluation of the jobsite should be
done prior to ordering the fan coil units to
determine any unique or additional steps that
may be required in order to properly demolish
an old unit and install a MIY.
WARNINGS: Page 2 (inside front cover) of this catalog
MUST be carefully reviewed before any
demolition and/or installation.
1. Adequately protect existing wall coverings
(paintings, wallpaper, etc.), furniture, carpeting,
and other surfaces when performing demolition
and installation work.
2. Remove supply-air grille and return-air/front panel
from existing unit.
3. Use a straight edge to outline drywall section for
removal, which will expose the entire front-face of
existing unit, apply painter’s tape to achieve clean
cut and prevent drywall damage.
Note: Typical area of drywall clearance for
replacement will be 81.5” x 15.5” on most
original units, although every application
may vary.
4. Carefully cut drywall at outer edges of unit, along
penciled outline, removing drywall from the floor
to the top of existing fan coil unit to expose the
entire front-face.
5. Cut and remove the upper-front, steel cabinet
panel flush with the sidewall of the existing unit.
6. Cut copper supply and return pipes with rotary
hand tool, leaving the ball valves and 1-2 inches
of copper tubing to connect to new coil.
Riser supply-return configurations and
temperature should be labeled prior to demolition,
and must be verified prior to installation, as they
may differ from the IEC standard convention.
7. Remove the upper coil support, coil, valve
package and any other components easily with a
screw gun.
8. Remove motor/blower assembly.
9. A hammer and chisel may be required to remove
blower deck.
10. Remove all other components remaining in
cabinet interior, so only a hollow, insulated, metal
shell of original unit remains.
11. Use sheet metal nibbler to trim existing cabinet
front-face flanges. Leave no more than 1/4” to
1/8” flange around perimeter of cabinet-front.
Figure 2. Use nibbler or reciprocating saw to remove flange
material
NOTE – It is important to remove as much flange material as possible to minimize
any interference with the new

to prevent hang-up when sliding in the
replacement unit
13. Clean inside of existing unit cabinet with vacuum,
after removal of all components.
