I. INSTALLATION
Note : The MAC 10 e3Filter 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.
Step 3. If using rigidly supported grid (usually 2” 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. A roll of high density gasket has been provided for use with ungasketed grids.
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. To install permanent power, remove the two screws that hold
the 2x4 j-box cover in place. Secure the electrical cable to the j- box. Connect L1 (black conductor) to the
black lead located in the j-box. Connect L2 (white conductor) to the common. Connect the ground (green
conductor) to the ground screw provided in the j-box, use an uninsulated lug for the connection. When the
permanent connection has been made, replace the j-box cover and reinstall the two screws. If optional power
cord was purchased, plug unit into a grounded receptacle.

recommended every six months.
Step 1. To gain access to the prefilter, remove the ceiling panel next to the unit, if applicable.
Step 2. Lift and remove the prefilter off the prefilter frame.(see Figure 2)
Step 3. Reassemble by reversing the above steps.

III. SERVICE : Removal and Replacement of the HEPA/ULPA Filter (Standard Unit)
WARNING !
Disconnect the unit from the electrical power source before attempting any service.
Step 1. Remove unit from ceiling.
Step 2. Remove the screws holding the HEPA/ULPA filter to the lid assembly.
Step 3. Lift the lid assembly off the HEPA/ULPA filter (see Figure 3). Discard the used filter as per requirements of the
applicable regulations.
Note : Before replacing with a new HEPA/ULPA filter, carefully inspect the new filter for any visible damage. Also
inspect the gasket in the “tee” bar to insure a tight seal. Replace as necessary.
Step 4. Replace with the new HEPA/ULPA filter and assemble by reversing the above steps.

V. SERVICE : Removal and Installation of the Motor
WARNING !
Disconnect the unit from the electrical power source before attempting any service.
WARNING !
Electrical service should be performed by licensed electricians or authorized ENVIRCO service technicians.
Step 1. To gain access to the motor/blower, remove the ceiling panel next to the unit, if applicable.
Step 2. Remove the prefilter off the prefilter frame.(see Figure 5)
Step 3. Remove the four screws from the electrical cover and tilt the electrical cover open..

Step 4. Make note of all wire locations for reinstallation later.
Step 5. Disconnect the brown, black and white wires from the capacitor.
Step 6. Disconnect the motor wiring from the speed control and the green/ yellow ground wire from the ground screw.
Step 7. Remove the six screws to free the motor/blower assembly from the lid assembly.(see Figure 6)
Step 8. Using a 10mm socket remove the four M6 bolts which hold the bottom motor plate from the standoffs. Again
using a 10mm socket remove the four M6 bolts from the motor.
Step 9. Replace with the new motor/blower and reassemble by reversing the above steps. Set the spacing between the
venturi ring and the blower wheel at 0.06”(0.15 cm) clearance. When reinstalling the M6 bolts through the
grommets into the bottom of the motor tighten the bolts using the lowest torque setting. Visually inspect the
blower wheel to assure the wheel is parallel to the bottom motor plate. Adjust the motor bolts to even the
wheel if necessary.

VI. SERVICE : Removal and Installation of the Optional Fluorescent Lamps
WARNING !
Disconnect the unit from the electrical power source before attempting any service.
Note : Accessibility to the fluorescent tubes is gained from the room side.
Step 1. To remove the fluorescent tubes, pull down on the two clips and swing down the light diffuser.

VII. ON/OFF Switch - Speed Control/Airflow Adjustment
All MAC 10 e3units are equipped with a two-position rocker switch and a speed control switch, which are located on the
side of the electrical box on top of the unit.
Electrical power to the fan may be disconnected by moving the toggle switch to the “O” position.
WARNING !
Disconnect the unit from the electrical power source before attempting any service.
Units are furnished speed controls which enable adjustment of airflow at any setting within the
recommended performance range. The speed control knob is located on side of the electrical box.
For 115v and 220v Units
Airflow/speed is adjusted by rotating the knob (see Figure 8):
Clockwise àLowers the speed
Counter-Clockwise àIncreases the speed
Fully rotating the speed control knob to the left or counter-clockwise will turn the unit off.
Note : When turning the unit “ON” from the “OFF” position of the speed control, the fan is at the highest speed.
Turning the speed control knob clockwise will lower the airflow.
For 277v Units
Airflow/speed is adjusted by rotating the knob:
Clockwise àIncreases the speed
Counter-Clockwise àLowers the speed
Fully rotating the speed control knob to the left or counter-clockwise will turn the unit off.
Note : When turning the unit “ON” from the “OFF” position of the speed control, the fan is at the lowest speed. Turning
the speed control knob clockwise will increase airflow.

VIII. Trouble Shooting :
Low Air Velocity
Step 1. Verify proper rotation, motor/blower rotates clockwise (CW). If unit is rotating counter clockwise (CCW),
verify that the capacitor has the black and wire wires on the same connector and the brown is on it’s own
connector. If the unit continues to rotate contact the factory.
Step 2. Check prefilter media; replace as necessary.
Step 3. Adjust variable speed control for higher blower output.
Step 4. Check power supply for proper voltage, amperage and distribution frequency.
Step 5. Replace HEPA/ULPA filter if the air velocity remains low.
High Air Velocity
Step 1. Adjust variable speed control for lower blower output.
Non-Laminar Flow and/or Excessive Contamination
Step 1. Insure that no large obstructions are upstream of airflow pattern.
Step 2. Determine that no other air-moving devices are operating in or around clean room which disrupt room’s airflow
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/ULPA filter. Seal or replace HEPA/ULPA filter as necessary.

XII. TESTING
Each MAC 10 e3filter 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.
Some of the testing procedures performed on the MAC 10 e3include aerosol challenge
of HEPA filters to assure specified performance, along with air velocity measurement and
adjustment tests.
