When a screwed-on silencer is used,
mount the volume booster with the silenc-
er facing downward.
Î
Mount the silencer properly using suit-
able tools and sealant to prevent thread
galling (seizure).
Î
If the silencer can become covered in
snow, iced up or dirt can collect, it must
be protected by a suitable fi xture/cover.
The IP 54 degree of protection is achieved
when the above mentioned requirements are
met.
