MAINTENANCE
5.1
GENERAL
Consistent and correctly performed maintenance will
ensure the compressor’s performance and extend its
operational life. See
on page 63 for a detailed
description of specific compressor components.
Before performing maintenance actions, read the
CIMA Safety Manual, if applicable. For engine
maintenance requirements and procedures, refer to
the
Engine Operator’s Manual
.
5.2
ENGINE COOLANT
REQUIREMENTS
This machine is factory filled with Mobil Delvac
Extended Life Coolant. It is an ethylene glycol based,
OAT inhibited coolant. This coolant is able to protect
the cooling system from freezing, extend the boiling
point, provide corrosion protection for all metals
within the cooling system; especially for systems with
aluminum radiators, provide liner cavitation
protection for heavy duty diesel engines, and be safe
to use with all seals/gasket materials.
This coolant 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.
The Engine Coolant type should follow these
recommended specifications:
• Organic acid technology (OAT)
• Premixed coolant pH range of 8.0 to 9.5.
• Contains no silicates, phosphates, borates,
nitrates and amines
• Solution states that it is formulated for use
in heavy duty diesel applications
• Protects all standard metals within the cool-
ing system (i.e. brass, copper, steel, solder,
cast iron, and aluminum.)
• Meets specification requirements of current
industry standards which include: ASTM D
3306, Cat EC-1
WARNING
DO NOT remove caps. Plugs and/or other
components when the compressor is run-
ning or pressurized. Shutdown the com-
pressor before removing any components.
WARNING
Follow lockout/tagout procedures of Sec-
tion 1 SAFETY.
WARNING
Please note: not following the recommen-
dations of the coolant requirements may
induce cooling system inefficiencies which
may result in engine overheating. Nonrec-
ommended coolant can drastically reduce
the life expectancy of the cooling circuit
and engine.
