Several Oil Level Controls have a 3/8” SAE oil equalization fit‑
ting. The equalization fitting allows the Oil Level Controls to
be interconnected, permitting oil transfer between a series of
compressors. This transfer is sometimes necessary due to a sud‑
den increase in oil level resulting from oil returning down the suc‑
tion line. If an equalizer is not required, a cap must be installed.
CAUTION: If a sudden load increase, or system defrost, causes
a large amount of oil to return through the suction line, the Oil
Level Control will not prevent the oil level from rising above the
control point.
The Sporlan Oil Level Control may be bolted either directly to the
compressor crankcase or, depending on the compressor model,
may be adapted to the crankcase by means of one of the adap‑
tors available, see table on page 8. Care must be taken when
installing an Oil Level Control to make sure the compres-
sor is leveled, and the Oil Level Control compressor fitting
and sightglass fitting are on the same elevation.
A slight amount of tolerance is provided in the bolt holes to allow
for rotating the Oil Level Control to make sure that the sightglass
is on the same level as the compressor connection. If the com‑
pressor and Oil Level Control are not level, a false reading may be
given in the sightglass.
