Service: Removal and Replacement of Standard HEPA/ULPA Filters

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.

Note: All filters should be visually inspected for freight damage before installation. It is necessary to use two workers when removing the filter and for installation to avoid twisting or separation of the media seals. Handle the filter only by the frame and never place anything on the upstream filter side of the filter. Additionally, it is important to keep the filter level to prevent any shearing force on the media itself.

For Standard Filters:
Tools Required: Phillips head screwdriver, 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.
Step 3. Lift the lid assembly off the HEPA/ULPA filter. (See Figure 4.)
Figure 4: Standard Filter Replacement

Discard the used filter as per requirements of the applicable regulations. Carefully install the filter deflectors into the new filter using the 5/32 rivets. Do not touch or place the filter deflectors on the HEPA/ULPA media pack. This could cause tears in the filter pack.
Note: Before replacing with a new HEPA/ULPA filter, carefully inspect the new filter for any visual damage. Also, inspect the gasket in the “tee” bar to ensure a tight seal. Replace as necessary.
Step 4. Replace with the new HEPA/ULPA filter and complete by reversing the above steps

Service: Removal and Replacement of RSR/E Gel Seal Filters

Note: All filters should be visually inspected for freight damage before installation. It is necessary to use two workers when removing the filter and for installation to avoid twisting or separation of the media seals. Handle the filter only by the frame and never place anything on the upstream filter side of the filter. Additionally, it is important to keep the filter 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 diffuse screen by removing the six 10-32×1/2 screws.
Step 2. Loosen the six 1/4×20 socket cap 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 and evenly away from the seal so that the gel remains in the filter gel track.
Step 3. Inspect filter for visual 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, have a certified professional replace the missing, dried out, and/or severely damaged gel.
Step 5. Place the filter evenly against the filter plenum housing of the RSR/E 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-clockwise around the filter and raise the filter into the gel.
Step 6. Reinstall screen. Reinstall and hand-tighten diffuse screen screws. Avoid over tightening the screen hardware.

Step 6. Disconnect 5-pin and 16-pin wire harnesses from the electrical box housing.
Step 7. Remove the eight screws to free the motor/blower assembly from the lid assembly. If using power drivers, set the unit to a low torque setting to avoid stripping the sheet metal screws (See Figure 6.)
Step 8. Using an adjustable wrench, loosen the two set screws that attach the blower wheel to the motor shaft.
Step 9. Mark the location of the motor support bracket (belly band), then loosen the bolt just enough to allow the motor support bracket to slide off the motor.
Step 10. Using the removed motor, mark the new motor with the location of the motor support bracket.
Step 11. Replace with the new motor and reassemble by reversing the above steps 1-8. Set the spacing at 0.25” (6.35 mm) clearance between the blower and the upper motor plate/filterer frame. This will give a 0.11” overlap between the venture ring and the blower.

Service: RSRE Motor Removal and Installation

Tools Required: 3/16 hex head wrench, Phillips head screwdriver

Note : It is highly recommended to also change the motor capacitor when changing the motor.

Step 1. To gain access to the motor, remove the gel seal HEPA/ULPA filter.
Step 2. Prior to removing motor/blower assembly, remove blower wheel to expose motor connectors on motor. Using an adjustable wrench loosen the two set screws that attach the blower wheel to the motor shaft. Disconnect the five and sixteen pin connectors from the motor.
Step 3. While supporting the motor blower assembly from below, remove the six screws on the underside of the venturi ring and lower the assembly. (See Figure 7). Note the baffle does not have to be removed to remove the motor/blower assembly.
Step 4. Before removal of the motor mount bracket, measure the precise location of the bracket on the motor. Remove the bracket.
Step 5. Replace with the new motor and reassemble by reversing the above steps. Set the location of the motor mount bracket as measured (see above
Step 6 ). Set the spacing at 0.25” (6.35 mm) clearance between the blower and the upper motor plate/ prefilter frame creating a 0.11” (2.80 mm) overlap between the wheel and the venturi ring. When reinstalling the assembly,  align the plate to insure that the leads will reach the electrical box.

Unit Control Box

ON/OFF Switch – Speed/Airflow 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.)
Figure 8: 3 Speed Switch Adjustment

Recommended fan speed during initial start-up and operation is the “LOW” speed. As airflow eventually decreases due to filter loading, fan speed may be increased by moving the rocker switch to the top or “MEDIUM” position, and finally to the “HIGH” position. Periodic airflow velocity readings (PerI.E.S. T. Specifications) should be conducted to determine the filter 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 prefilter 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 filter 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 airflow pattern.
Step 2. Determine that no other air-moving devices are operating in or around cleanroom 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 filter. Seal or replace HEPA filter as necessary.

Testing

Each MAC 10 LEAC filter unit is thoroughly tested at the factory before shipment. However, because of the “rigors” of shipping, ENVIRCO encourages its re-test 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 filters to assure specified performance, along with air velocity measurement and adjustment tests. No DOP is used on MAC 10 Filters, unless requested.
