Fan Filter Unit

Installation
Note:
The MAC 10 LEAC2 Fan Filter Unit is completely assembled at the factory with the exception of the optional ¼” (0.64
cm)-20 eyebolts that are used when hanging the unit from an engineered support system and with installation of the HEPA/
ULPA filters. (Eyebolts are not included and need to be ordered separately, p/n 222449-001.)
Step 1.
Carefully remove the unit from the shipping carton and inspect for any damage that may have occurred during
transportation. (See Figure 1.)
Note:
When ordering RSRE units, the HEPA filters may be shipped separately to be installed into units after the fan box has
been installed.

Step 2.
Wipe down plastic bag and move unit into cleanroom. (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 engineered support system with
eyebolts, s-hooks, and chain. Screw the four eyebolts into the nutserts on the lid assembly before lifting into an overhead
position. (See Figure 2.)
Note:
Confirm fan dimensions to match T-grid dimensions. Special size units are available to fit specific cleanroom grid systems.

Step 3.1.
If using a support grid, continue...
Step 4.
Raise the unit and secure it into place using the chosen support system method suspended from a structural support
bracing.
Step 5.
Have an electrician wire the unit to the appropriate voltage, according to the wiring diagram (page 13), and all national
and local electrical codes. If optional power cord was purchased, plug unit into a grounded receptacle. The optional power
cord is not acceptable for plenum installations.
Step 6.
Turn on the power using the rocker switch (ON/OFF) located on the electrical box. For RSRE units, let the unit run for
a few hours to purge off particulate (if filters are shipped loose) that may be adhered to the inside of the unit before installing
the filters. Do not run fan at full speed, as this may cause overload condition.
Note:
Your fan filter controls may have been shipped separately.
