Section 6: Maintenance; General; Engine Coolant Requirement For Radiators; Daily Maintenance - Sullair 185CFM User Manual

Do not remove caps, plugs and/or other compo-
nents when the compressor is running or pres-
surized. Shutdown the compressor before
removing any components.

6.1 General

Consistent and correctly performed maintenance will
ensure the compressor's performance and extend its
operational life. See Section 6.9: Part replacement and
adjustment procedures on page 46 for a detailed descrip-
tion of specific compressor components. Before perform-
ing maintenance actions, read the CIMA Safety Manual,
if applicable. For engine maintenance requirements and
procedures, refer to the Engine Operator's Manual.
6.2 Engine coolant requirement for
radiators
The coolant provided with Sullair portable air compres-
sors is ethylene glycol based, 50/50 mixture, and should
never be mixed with a different coolant type, color or
brand. If radiator coolant is to be added, for any reason,
be sure that the coolant added is the same as what is in
the cooling system, as well as what is recommended.
Refer to the Maintenance section of the Engine Opera-
tor's Manual for proper engine coolant specifications and
instructions. Ensure that the proper coolant is used when
adding engine coolant to the machine. If you are not sure
of the coolant that is installed originally or want to change
to a different type, the cooling system must be cleaned
with a commercial cleaning agent and completely flushed
and filled with distilled water several times to remove all
traces of old coolant. Then, fill the system with the rec-
ommended coolant using only one brand/type. Cross
contamination which is caused by adding different types
of engine coolants may result in the coolant additives to
deplete (dropout); thus leaving radiator surfaces unpro-
tected. Corrosion to radiator surfaces may occur, thus
reducing radiator life expectancy. It is extremely import-

ant to evacuate/purge all air within the cooling system
before replacing the radiator cap.

6.3 Daily maintenance

See Section 4.3: Starting the compressor on page 37 for
general operation.
The radiator and engine cooling system must be
drained and flushed periodically. Refer to the
OEM Engine Manual for more information.
Replace the coolant with a solution of 50% eth-
ylene glycol and 50% water or as required for
your geographic location. Do not use a leak
sealing type of antifreeze. Should a 100% water
solution be used, a non-chromate rust inhibitor
must be added. Do not mix coolant types.
Dispose of fluids in accordance with applicable
federal, state and local regulations.
6.4 Maintenance after initial
50 hours of operation
After the initial 50 hours of operation, the following main-
tenance actions are required to eliminate contaminants
from the system:
• Clean the scavenge return line orifice and
change the strainer.
• Change the compressor fluid filter.
• Check the Engine Operator's Manual for ser-
vice requirements.
• Check the fuel filter for water.
• Confirm that the receiver tank cover bolts are
tightened to 60 ft-lbs (81 N•m).
