Freeze Protection
Where freeze protection is required use antifreeze made especially for hydrolic systems such
as inhibited Propylene Glycol. DO NOT use automotive type antifreeze. Follow antifreeze
manufacturer’s directions for quantity. A 50% solution provides protection to –30 degree F. For
boiler water content see page 11.
