IMENSIONS
MLZ / MLM scroll compressors come equipped
with a threaded oil sight glass with 1"1/8 - 18 UNF
connection. It can be used for a visual check of the
oil amount and condition or it may be replaced by
an accessory oil management device. The oil level
must be visible in the sight glass during opera-
tion.
The oil fill and drain connection and gauge port
is a 1/4" male flare connector incorporating a
schrader valve.
MLZ / MLM scroll compressors are factory deliv-
ered with brazed connections only. Dedicated
rotolock adaptors and adaptor sets are available
