REPLACING THE COOLANT
Drain
•
Completely drain the entire cooling system.
•
Used coolant must be disposed of or recycled in
accordance with legislation and local regulations.
Flush
•
Flush twice with clean water. Used coolant must
be disposed of or recycled in accordance with
legislation and local regulations.
•
Using the Atlas Copco Instruction book,
determine the amount of PARCOOL EG required
and pour into the radiator top tank.
•
It should be clearly understood that proper
cleaning reduces contamination risks.
•
In case of "other" coolant residues inside the
system, the coolant with the lowest properties
influences the quality of the ‘mixed’ coolant.
Fill
•
To assure proper operation and the release of
trapped air, run the engine until normal engine
operation temperature is reached. Turn off the
engine and allow to cool.
•
Recheck coolant level and add coolant mixture if
necessary.
CLEANING COOLERS
Keep the coolers clean to maintain the cooling
efficiency.
Then clean by air jet in reverse direction of normal
flow.
Steam cleaning in combination with a cleansing agent
may be applied.
Close the service door(s).
In case of a mix of different coolant
products this type of measuring might
provide incorrect values.
Remove any dirt from the coolers with a
fibre brush. Never use a wire brush or
metal objects.
To avoid damaging the coolers, angle
between jet and coolers should be
approx. 90° (do not use jet at max.
power).
