WARNING
Ethylene Glycol antifreeze is con-
sidered toxic. Dispose of it according to local
regulations for hazardous substances.
Use the best quality ethylene glycol antifreeze solu-
tion available. It should be fully formulated with rust
inhibitors and coolant stabilizers. A 50/50 mixture of
water and ethylene glycol is recommended to pro-
vide protection from freezing down to -34
°
F
(-37
°
C).
Use fresh water that is low in minerals and corrosive
chemicals for the coolant mixture. Distilled water is
best.
See Specifications (Section 12) regarding coolant
capacity.
