ntt:: Only OAT extended life coolants (Chevron Delo® XLC or
equivalent) should be added to Thermo King systems.
Conventional coolants should not be used (Typically identified
by green or blue-green color). If a conventional coolant is
combined with the Thermo King factory fill up to 25% by volume,
the coolant must be changed at the next service opportunity.
Above 25%, the coolant must be changed immediately.
Conventional coolants dilute/interact with the additive packages
of extended life coolant which significantly reduces the service
life of the coolant.

e:: The use of 55/45% pre-mixed ELC is recommended to ensure that
deionized water is being used. If 100% full strength concentrate is
used, deionized or distilled water is recommended instead of tap
water to ensure the integrity of the cooling system is maintained.
