Only NEW, moisture-free refrigerant oil should be used in the
air conditioning system. This oil is highly refined and dehydrated so
moisture content is less than 10 parts per million. The oil container
must be tightly closed at all times when not in use, or moisture from
the air will be absorbed into the refrigerant oil.
SERVICING PRECAUTIONS
DISCHARGING SYSTEM
Discharge A/C system, using approved refrigerant
recovery/recycling equipment that meets SAE J2210 requirements. Always
follow recovery/recycling equipment manufacturer's instructions. After
refrigerant recovery process is completed, replace any refrigerant oil
removed with the same amount of NEW refrigerant oil.
DISCONNECTING LINES & FITTINGS
After system is discharged, carefully clean area around all
fittings to be opened. Always use 2 wrenches when tightening or
loosening fittings. Some refrigerant lines are connected with a
coupling. Special tools may be required to disconnect lines. Cap or
plug all openings as soon as lines are removed. DO NOT remove shipping
caps from replacement components until ready to install.
CONNECTING LINES & FITTINGS
NOTE: Ensure all replacement component connections match
connections of system being worked on.
Always use a NEW gasket or "O" ring when connecting lines or
fittings. Coat "O" ring with NEW refrigerant oil and ensure it is not
twisted during installation. Always use two wrenches to prevent damage
to lines and fittings.
PLACING SYSTEM IN OPERATION
After component service or replacement has been completed and
all connections have been made, thoroughly evacuate system with a
vacuum pump. Charge system with proper amount of refrigerant and
perform leak test. See REFRIGERANT OIL & REFRIGERANT SPECIFICATIONS
table for system capacities. Ensure there are no leaks at any fitting
that has been opened. After system has been leak tested, check system
performance.
NIPPONDENSO 10-CYL.
Eclipse 2.0L Non-Turbo & Montero
Replacement compressor is shipped with NEW refrigerant oil.
Drain, measure and discard refrigerant oil from old compressor. Drain
NEW refrigerant oil from replacement compressor equal to difference
between amount drained from old compressor and amount shipped in
replacement compressor. If any other components are replaced, add NEW
refrigerant oil as specified. See COMPONENT REFRIGERANT OIL CAPACITIES
(MITSUBISHI - NIPPONDENSO 10-CYL.) table.
