compressed air system by closing the isolation valve
and venting pressure from the drip leg.
Ensure the main power disconnect switch is locked
open and tagged. (See Figure 5.14-1).
Tools Required
Screwdriver

local codes.
Inspection
Visually check the outside of the cooler cores to be
certain that a complete outside cleaning of the cooler is
required. Frequently dirt, dust or other foreign material,
may only need to be removed to remedy the problem.
When the cooler is covered with a combination of oil,
grease or other heavy substances that may affect the
unit’s cooling, then it is recommended that the cooler
cores be thoroughly cleaned on the outside.
Strong cleaners can harm
aluminum cooler parts. Follow cleaner
