REMOVAL AND REPLACEMENT OF THE HEPA FILTER WITH GEL SEAL
WARNING!
The HEPA filter may be protected by an expanded metal screen. This is to prevent accidental touching of the filter
media. It is not meant to allow handling of the filter in these areas. Handle the filter ONLY by the frame.
Tools required: Flat screw driver.
NOTE:
Nailor recommends two people to remove and install the HEPA filter in the unit.
Step 1
Shut off airflow to the diffuser.
Step 2
Using a flat screwdriver, release the face frame by rotating the four (4) fasteners a quarter-turn counter clock-wise.
Unhook the safety cables from the filter spacers. Set the frame aside.
Step 3
USE TWO PEOPLE TO SUPPORT THE FILTER and rotate the filter clips until clip is clear of the filter.
Step 4
Allow gravity to pull the filter away from the unit. If installing a new filter; discard the filter in an appropriate manner.
Step 5
If the unit is equipped with the HEPA-lert battery powered LED system, replace the battery at this time.
Step 6
Unpack the new filter and inspect for shipping damage. If damage is found, do not install in unit; call Nailor for
replacement arrangements.
Step 7
Using two people, raise the filter into place assuring the seal edge is approximately in the center of the gel
channel. The spacers beneath the filter clips will help align the filter.
Step 8
While supporting the filter by its frame, rotate the filter clips so that the clips are supporting the filter frame.
Wait at least 30 minutes before performing any challenge testing to allow the gel to fully adhere to the unit.
Step 9
Raise the face frame back into place, re-attach the safety chains and secure quarter-turn fasteners.
Step 10
Inspect all gaskets and seals for integrity.
