Note: C-, D-, and E-frame compressors have two
plugs; B-frame compressors have one plug.
12. De-energize the oil solenoid valve.
13. Change the oil filter (number 38; not insulated).
Change the cold oil filter (number 48; insulation will
need to be removed).
14. Perform pressure test.
15. Evacuate the unit to a minimum of 500 microns and
perform a rise test.
16. Add the total oil charge according to
AFD to the RTHD chiller requires more oil than the
original factory configuration.
a. Add enough Solest 120 (OIL00315/317) to the oil
filter (number 7) to fill the filter.
b. Add remaining total Solest 120 (OIL00315/317)
charge at the oil sump (number 7).

Important:
Be sure to either run the evaporator and
condenser pumps when adding refrigerant
to prevent freezing or verify that the water
has been drained to prevent freezing tubes.
17. Compare amount of refrigerant removed in previous
step to the nameplate charge. Charge appropriately at
evaporator (number 25) according to the table for units
with an AFD. Add refrigerant as needed to ensure the
unit is fully charged.
Important:
Oil charges shown in
RTHD chillers with AFD; when retrofitting
existing RTHD chillers with AFD, increase oil
charge shown in
based on how much oil was extracted
during oil removal process.
18. At the oil sump, apply provided oil label sticker listing
the new oil, OIL00315.
