The HRE-504 contains LPU surge arrestors that may be replaced in the field, if needed. See the following for
instructions on replacing the LPU surge arrestors and see
for replacement part numbers.
Additionally, ADC recommends that the O-ring be closely examined whenever the housing is opened for
maintenance. If the O-ring is damaged, replace it.
To replace the stainless steel dome cover it is necessary to replace the following items: stainless steel dome cover,
metal locking clamp, and O-ring. It is recommended that the desiccant bags be replaced when the enclosure is
opened. Use Davison Chemical Corp. Proteck-Sorb-121 or equivalent desiccant.
To Replace LPU Arrestor Boards:

Remove the clamp and dome cover as described in
“Opening the Enclosure” on page 18

If an enclosure plug receives severe lightning stress, ADC recommends replacing the LPU
board for that plug.
