1INSTALLATION
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 receptacle. The
optional power cord is not acceptable for plenum installations.

Filter (Standard Unit) WARNING!
Disconnect the unit from the electrical power source before attempting any
service.
WARNING!
The Standard Filter is protected with an expanded metal face screen. This is
never to be used to handle the filter. It is only for protection against an accidental
touch of the filter. Only handle the filter by the frame.
Tools Required: Phillips Head Driver, Battery Operated Drill with a 5/32 Drill
Bit, Rivet Hand Tool, Ø5/32 aluminum rivet grip range .126-
.187
Step 1. Remove unit from ceiling.
Step 2. Remove the 10 screws holding the HEPA/ULPA filter to the lid assembly.

5 SERVICE: Removal and Installation of the Room Side
Replaceable Gel Seal Filter (RSR/RSRE)
WARNING!
Disconnect the unit from the electrical power source before attempting any
service.
WARNING!
The RSR Filter is protected with an expanded metal face screen. This is never to
be used to handle the filter. It is only for protection against an accidental touch of
the filter. Only handle the filter by the frame.
Tools Required: Phillips Head Driver
3/16” hex head wrench
Manpower Required: 2
Step 1. Remove the diffuser screen by removing the 6 each 10-32x1/2 screws.
Step 2. Loosen the six 1/4x20 socket head screws far enough to rotate the filter clip
90°. The filter will not drop during this operation. Slowly pull the filter away
from the knife-edge seal, taking care not to touch the filter face during this
operation. It is important to pull the filter slowly away from the seal, so that the
gel remains in the filter gel track.
Step 3. Inspect filter for visible damage, if damaged set aside for replacement or repair.
Step 4. Inspect the gel seal, if reinstalling the removed filter. Determine if the gel has
lost its ability to seal, if so repair the gel.
Step 5. Place the filter against the filter-sealing surface of the RSR unit. Install filter
clips and screws. The clips can be rotated and angled into place. Using the
clips as a lever the filter can be seated. It is recommended to work either
clockwise or counter clock wise around the filter, raise the filter into the gel.
Step 6. Reinstall screen.
