Danfoss MLZ/MLM116 scroll compressors come
equipped with a sight glass (1"1/8 - 18 UNF)
which may be used to determine the amount and
condition of the oil contained within the sump.
MLM/MLZ116: 2"1/4 Rotolock connector allowing
the use of 2"1/4 - 1"3/8. This connection must be
used to mount an oil equalization line when two
compressors are mounted in parallel.
The oil drain connection allows oil to be
removed from the sump for changing, testing,
etc. The fitting contains an extension tube into
the oil sump to more effectively remove the
oil. The connection is a female 1/4" flare fitting
incorporating a Schrader valve and is mounted
on MLM/MLZ116 models.
The oil fill connection and gauge port is a 1/4"
male flare connector incorporating a Schrader
valve.
Dedicated Rotolock adaptors and adaptor sets
are available as accessories.
