b. Equivalent system freeze protection products
may be used in lieu of product referenced above.
In general, freeze protection for new or existing
systems must use specially formulated glycol,
which contains inhibitors, preventing the glycol
from attacking the metallic system components.
Insure that system fluid contains proper glycol
concentration and inhibitor level. The system should
be tested at least once a year and as recommended by
the manufacturer of the glycol solution. Allowance
should be made for expansion of the glycol solution.
Warning
Poison Hazard. Use only inhibited propylene
glycol solutions specifically formulated for
hydronic systems. Do not use ethylene glycol,
which is toxic and can attack gaskets and seals
used in hydronic systems. Use of ethylene
glycol could result in property damage, personal
injury or death.
