MAC 10®LEAC2
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 lters. (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 lters may be shipped separately to be installed into units after the fan box has
been installed.
Figure 1: Unboxing
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 exible 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: Conrm fan dimensions to match T-grid dimensions. Special size units are available to t specic cleanroom grid systems.
Figure 2: Hanger Supports
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 lters are shipped loose) that may be adhered to the inside of the unit before installing
the lters. Do not run fan at full speed, as this may cause overload condition.
Note: Your fan lter controls may have been shipped separately.

■Unit Control Box
ON/OFF Switch - Speed/Airow Adjustment
MAC 10 LEAC2 units are equipped with a two-position rocker switch (ON/OFF) and Solid State Speed Control (SSSC), which
are located on the front side of the electrical box. (See Figure 3.)
Recommended fan speed during initial start-up and operation is at a low speed. As airow eventually decreases due to lter
loading, fan speed may be increased by moving the SSSC rst to a medium speed and eventually to a high speed. Periodic
airow readings (per IEST specications) should be conducted to determine the lter condition and appropriate fan setting.
Figure 3: Speed/Airow Adjustment
■ENAC Control Card (Optional)
MAC 10 LEAC2 units will have the capability to include a unique ENAC control card in lieu of the SSSC for networking
purposes. Contact the factory for part number.

■Service: Removal and Replacement of RSRE Gel Seal Filters
Note: All lters should be visually inspected for freight damage before installation. It is necessary to use two workers when
removing the lter and for installation to avoid twisting or separation of the media seals. Handle the lter only by the frame
and never place anything on the upstream lter side of the lter. Additionally, it is important to keep the lter level to prevent
any shearing force on the media itself.
For RSRE Filters:
Tools Required: Phillips head screwdriver, 3/16” ball driver hex head wrench
Step 1. Remove the diffuser screen by removing the six 10-32x1/2 screws.
Step 2. Loosen the six 1/4x20 socket cap head screws far enough to rotate the lter clip 90°. The lter will not drop during this
operation. Slowly pull the lter away from the knife-edge seal, taking care not to touch the lter face during this operation. It
is important to pull the lter slowly and evenly away from the seal so that the gel remains in the lter gel track.
Step 3. Inspect lter for visual damage. If damaged, set aside for replacement or repair.
Step 4. Inspect the gel seal if reinstalling the removed lter. Determine if the gel has lost its ability to seal. If so, have a certied
professional replace the missing, dried out, and/or severely damaged gel.
Step 5. Place the lter evenly against the lter plenum housing of the RSRE unit. Install lter clips and screws. The clips
can be rotated and angled into place. Using the clips as a lever, the lter can be seated. It is recommended to work either
clockwise or counter-clockwise around the lter and raise the lter into the gel.
Step 6. Reinstall screen. Reinstall and hand-tighten diffuser screen screws. Avoid overtightening the screen hardware.

■Limited Warranty
LIMITED WARRANTY: Unless otherwise expressly
stated in ENVIRCO’s published specifications for the
Goods, ENVIRCO warrants that Goods are free from
defects in material and workmanship, except for services
which are warranted to be performed in a competent and
diligent manner in accordance with any mutually agreed
specifications. The foregoing warranty shall apply for
eighteen (18) months from the date of shipment from
ENVIRCO’s facility, except for services for which the
warranty shall apply for ninety (90) days from the date
of performance (the “Warranty Period”). Provided Buyer
informs ENVIRCO in writing of any breach of warranty
prior to the expiration of the applicable Warranty Period,
ENVIRCO shall, as its sole obligation and Buyer’s sole
and exclusive remedy for any breach of this warranty,
repair or replace/re-perform the Goods which gave rise
to the breach or, at ENVIRCO’ option, refund the amounts
paid by Buyer for the Goods which gave rise to the breach.
Any repair, replacement or re-performance by ENVIRCO
hereunder shall not extend the applicable Warranty Period.
The parties shall mutually agree on the specifications of
any test to determine the presence of a defect. Unless
otherwise agreed upon by ENVIRCO in writing, Buyer shall
bear the costs of access, de-installation, re-installation
and transportation of Goods to ENVIRCO and back to
Buyer. These warranties and remedies are conditioned
upon (a) the proper storage, installation, operation,
and maintenance of the Goods and conformance with
the proper operation instruction manuals provided by
ENVIRCO or its suppliers or subcontractors, (b) Buyer
keeping proper records of operation and maintenance
during the applicable Warranty Period and providing
ENVIRCO access to those records, and (c) modification
or repair of the Goods only as authorized by ENVIRCO.
ENVIRCO does not warrant the Goods or any repaired
or replacement parts against normal wear and tear or
damage caused by misuse, accident, or use against the
instructions of ENVIRCO. Any modification or repair of any
of the Goods not authorized by ENVIRCO shall render
the warranty null and void. EXCEPT AS EXPRESSLY
SET FORTH HEREIN, ENVIRCO MAKES NO OTHER
WARRANTIES, EXPRESS OR IMPLIED, INCLUDING,
BUT NOT LIMITED TO, ANY IMPLIED WARRANTIES
OF MERCHANTABILITY, NON-INFRINGEMENT OR
FITNESS FOR A PARTICULAR PURPOSE WHICH ARE
HEREBY DISCLAIMED TO THE EXTENT PERMITTED
BY APPLICABLE LAW.
■Testing
Each MAC 10 LEAC2 filter unit is thoroughly tested at
the factory before shipment. However, because of the
“rigors” of shipping, ENVIRCO encourages its re-test after
installation.
ENVIRCO recommends that the customer contact an
independent organization, with technicians trained and
experienced in performance evaluation and maintenance
of clean air equipment.
HEPA filters (Type J) are tested to IEST-RP-00034.
ULPA filters are tested to (Type F) IEST-RP-00034.
All filters are UL 900 recognized. Your filters may have
special requirements; please see original engineering
specifications for your specific project.
All units that are airflow tested at ENVIRCO are tested
using a Shortridge Airdata Multimeter 870 with a Velgrid
head. The recommended method of reading is to place
one corner of the Velgrid head 1-1/4” from the corner of
the filter face, take four readings evenly spaced along the
four foot side, then repeat these reads three additional
times. This gives a total of eight readings to test the unit.
All advertised data is based on using the Velgrid with eight
readings (128 velocity points). ENVIRCO recognizes that
using eight readings during a cleanroom start-up may be
time-consuming and recommends that using four Velgrid
readings taken on each 2x2 filter section will approximate
the same as eight readings.
