4 SERVICE: Removal and Installation of the Room Side
Replaceable Gel Seal Filter – Extrusion Housing (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:
5/32” hex head wrench
Manpower Required: 2
Step 1. Remove the diffuser screen by removing the four M5x35 socket head screws
securing the screen to the filter. (Figure 4)
Step 2. Loosen the six M5x16 socket head screws far enough to rotate the filter clip
180 °. The filter will not drop during this operation. Using the clips as handles,
slowly pull the filter away from the knife-edge seal. 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.
