Emergency Measures/Warranty Repair
DO NOT clean OIL LINE with detergent used for copper
pipes. After fully understanding the usage instructions of the
detergent, keep the product completely sunk in a container
filled with the detergent for a period time.
6.3.3 COOLER DRAINING
When the system is stopped and water is not supplied to the
heat exchanger anymore, ALL water drain plugs located on the
floating cover should be opened and water completely drained
out of the cooler.
Stagnant water leads to high corrosion level and reduce
drastically lifetime of the cooler.
Drain the cooler during winter season to avoid water freezing
and tubes bursting.
7. Emergency Measures
7.1 Measures for leakage by casting breakage
• Block pressure into the working system
immediately when the casting cover of equipment is
broken due to external shock.
• Discontinue the supply of cooling water to the
cooling line. Drain the tube side (refer to draining).
•
Unscrew the bolts screwed on the cover.
•
Remove O-ring and check whether or not it may be
reused, and if not, replaced.
•
Assemble a new casting cover with bolts as what it used
to be.
7.2 Replacement measures for copper pipe breakage
•
Immediately discontinue operation and supplying cooling
water to the cooling line when the copper pipe is broken
as a result of a freeze burst during colder seasons.
•
If cooling water continues being supplied continuously
when the copper tube is broken, water and oil may mix
inside the heat exchanger, which may result in damage
to your system. Please pay extra attention to this issue.
•
Broken copper pipe may not be repaired or replaced by
the customers.
Ensure that you consult and repair or replacement, via
appropriate services through after Sales Team or Local
Customer Service Center of Parker OLAER.

1.
Discontinue operating the supplying line of cooling
water and the system when cooling water leaks due to
gasket breakage.
2.
Unscrew the bolts screwed on the casting cover.
3.
Remove gasket and insert a replacement.
4.
Reassemble the casting cover.
7.4 Measures for Water & Oil leagage in in-out let
1.
First, discontinue operating the system and the cooling
water line when oil or water leakes in IN-OUTLET.
2.
Check if nipple in IN-OUTLET is assembled properly. If it
is not fastened securely, water and oil may leak.
3.
For PT screws, water and oil leakage may be prevented
effectively by winding Teflon tape on it or by using it with
sealing materials.
