INSTALLATION
Note: The MAC 10 LE-AC Fan Filter Unit is completely assembled at the factory with
the exception of the optional ¼” (0.64 cm)-20 eyebolts, which can be used
when hanging the unit from an overhead structure.
Step 1. Carefully remove the unit from the shipping carton and inspect for any damage
that may have occurred during transportation. (See Figure 1)
Step 2. Wipe down plastic bag and move unit into clean room. (Double bagging is
available upon request.)
Step 3. If using rigidly supported grid (usually 2” (50 mm) or wider), raise unit through
ceiling and lower onto the gasketed grid. If using a flexible grid (typically
supported with wires) the unit must be secured to an overhead structure with
eyebolts, s-hooks and chain or ¼-20 all thread. A roll of high-density gasket has
been provided for use with ungasketed grids. Note: special size units are
available to fit specific clean room grid systems.
Step 4. Have an electrician wire the unit to the appropriate voltage (115V, 220V, 277V
AC), according to the wiring diagram in section IX and local electric codes. If
optional power cord was purchased, plug unit into a grounded recepta cle. The
optional power cord is not acceptable for plenum installations.
