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 RSR/E 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.

■Unit Control Box
ON/OFF Switch - Speed/Airow Adjustment
All MAC 10 units are equipped with a three-position rotary switch, which is located on the side of the electrical box. (See Figure 8.)
Recommended fan speed during initial start-up and operation is the “LOW” speed. As airow eventually decreases due to lter
loading, fan speed may be increased by moving the rocker switch to the top or “MEDIUM” position, and nally to the “HIGH”
position. Periodic airow velocity readings (Per I.E.S. T. Specications) should be conducted to determine the lter condition and
appropriate fan speed setting.

■Troubleshooting
UNIT IS NOT ADJUSTABLE
Verify that rotation of the knob on the visual speed control does not change the RPM or Flow Index display on the unit. If
rotating does nothing, remove the electrical box cover and remove the 4-pin connector from the Visual Speed control and
install in 180 degrees rotated. Again adjust the knob. The 4 pin connector is on the 18” (31.8 mm) white conductor.
LOW AIR VELOCITY
Step 1. Check prelter media; replace or clean as necessary.
Step 2. Adjust visual speed control for higher blower output.
Step 3. Check power supply for proper voltage, amperage and distribution frequency.
Step 4. Replace HEPA lter if the air velocity remains low.
HIGH AIR VELOCITY
Adjust visual speed control for lower blower output.
NON-LAMINAR FLOW AND/OR EXCESSIVE CONTAMINATION
Step 1. Ensure that no large obstructions are upstream of airow pattern.
Step 2. Determine that no other air-moving devices are operating in or around cleanroom which disrupt room’s airow pattern.
Step 3. Check air velocity and, if low, conduct the “Low Air Velocity” procedure outlined above.
Step 4. Conduct smoke and photometer test on HEPA lter. Seal or replace HEPA lter as necessary.

after installation. Additional, for large installations it
is recommended to bench test 5% of the units prior to
installation.
ENVIRCO recommends that the customer contact an
independent organization, with technicians trained and
experienced in performance evaluation and maintenance
of clean air equipment.
Some of the testing procedures performed on the MAC
10 LEAC include PSL challenge of HEPA/ULPA lters
to assure specied performance, along with air velocity
measurement and adjustment tests. No DOP is used on
MAC 10 Filters, unless requested.
