2. Allow a minimum of 24 inches (610mm) clearance from access
panels.
3. Recommended method of securing for typical applications:
a. If fan coil is away from wall, attach pipe strap to top of fan coil
using No. 10 self-tapping screws. Angle strap down and away
from back of fan coil, remove all slack, and fasten to wall stud of
structure using 5/16" lag screws. Typical both sides of fan coil.
b. If fan coil is against wall, secure fan coil to wall stud using 1/8"
wide right-angle brackets. Attach brackets to fan coil using No.
10 self tapping screws and to wall stud using 5/16" lag screws
(Fig. 7).
NOTE: Modular units can be disassembled and components moved
separately to installation area for reassembly. This process
accommodates small scuttle holes and limiting entrances to installation
sites (Fig. 8).
