ROUTINE MAINTENANCE
Remove accumulated dust and dirt from the internal
componentsofthecoolerbyblowingitoutwithalow-
pressureairhoseorremovingitwithavacuumhose.
PERIODIC MAINTENANCE
In dirty or dusty environments or if biological growth
occursinthecoolant,itmaybenecessarytoflushthe
coolant reservoir. Drain the old coolant, rinse the
inside of the reservoir and circulate rinsing solution
through the coolant system. Add new coolant when
cleaningisfinished.
It is recommended to flush the
coolant at least once a year. A cooling system free
from debris offers increased cooling efficiency and
longer pump and torch life. See the Coolant
TreatmentRecommendationinthis“SectionD-2”.
NOTE: Pure solutions and mixtures of, or materials
(i.e. towels wetted) with ethylene glycol are toxic to
humans and animals. They must not be haphazardly
discarded, especially by pouring liquids down the
drain.ContactthelocalEPAofficeforresponsibledis-

HEAT EXCHANGER
To maintain maximum cooler efficiency, the heat
exchanger should be kept free of dust and dirt build-
up.Cleantheheatexchangerperiodicallyusingavac-
