VACUUM PUMP MAINTENANCE
Oil must be periodically changed in the vacuum pump
to ensure continued performance. The RHS980 will
display a reminder after every ten hours of vacuum
pump use.
A drain port and fill port for the vacuum pump protrude
through the rear wall of the RHS980 to the left of the
handle. A sight glass for viewing the oil level in the
vacuum pump is located on the end of the fill port.
Remove Fill Port Cap to optimize fluid draining. Drain
oil from the drain port and refill with new oil through the
fill port. Use oil which is specially formulated for a
vacuum pump.

The oil level should be visible approximately one-half
the way up in the sight glass. DO NOT OVERFILL!
Please be advised, vacuum pump overfilling or
running the machine without service hoses being
connected can cause vacuum pump oil to be
discharged out through the vacuum pump vent
tube at the bottom of the machine. Overfilling can
be corrected. Refer to MAINTENANCE OPTIONS
section for instructions regarding machine reset.
COMBO FILTER MAINTENANCE
The RHS980 combo filter must be replaced after every
150 LB (68 KG). of refrigerant has been recovered
from A/C systems. An alert will display when the filter
life is at 100 LB (45.35 KG). The RHS980 will shut
down when the filter life is at 150 LB (68 KG). A new
filter must be installed and a serial number entered to
re-start the RHS980.
A special routine for changing the combo filter is
explained in MAINTENANCE OPTIONS section of this
manual.
Remove the document pocket on the left side of the
RHS980 to gain access to the combo filter. The combo
filter is on the right side of the manifold as shown in
the photo. A hex on top of the filter is provided to make
filter removal and installation easy. Use an open end
wrench on this hex. New o-rings are provided with the
replacement filter. Apply a light coating of mineral oil
to the o-rings prior to reassembly.
A serial number is printed on a label attached to the
new filter. Make a note of this number as it may not be
visible when the filter is installed. This serial number
must be entered to reset the 150 LB (68 kg) filter life
routine. Refer to MAINTENANCE OPTIONS section
for instructions regarding machine reset.
