CAUTION: The vacuum pump is shipped
without oil in the reservoir . Failure to add oil
will damage the vacuum pump .
2. Remove the plug from the vacuum pump oil fill
port.
3. Attach the flexible tube/cap to the oil bottle (from
the accessory kit); pour only five (5) ounces
of vacuum pump oil into the fill port. Note: You
will top off the oil in the next step as the vacuum
pump is running.

The unit pulls a 3-minute vacuum to clear all
internal air before proceeding.
Note: The “burping” noise heard during this
process indicates air is being purged from the
system—this is normal.
CAUTION: The unit is programmed
to run the setup procedure as outlined
here . To prevent personal injury, do
NOT operate the unit at any other
time without the oil fill port plug
installed, because the vacuum pump is
pressurized during normal operation .
