APPLICATIONS

1. Fan coil unit must be secured to the structure using field-supplied

hardware.

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. Typically both sides of the fan 

coil. 

b. If fan coil is against wall, secure fan coil to wall stud using 1/8” 

(3mm) wide right-angle brackets. Attach brackets to fan coil 

using No. 10 self tapping screws and to wall stud using 5/16” lag 

screws (refer to Fig. 8).
