MAINTENANCE
Moving parts are totally automatic and highly reliable and ordinary maintenance is reduced to a minimum. This
maintenance, however, must be performed at the prescribed intervals.
Failure to perform maintenance compromises heat exchanger operation and durability and invalidates guarantee
coverage.
PREVENTATIVE MAINTENANCE SCHEDULE
TWICE A YEAR
Check that the heat exchange bank and fan protection grilles are clean and that dirt does not
prevent the passage of air.
Verify there are no abnormal noises during operation.
ANNUALLY
Check that fan motors and other components do not show abnormal vibrations or show signs of
overheating.
Check that water passage through the pipelines is not clogged by dirt.
REPLACEMENT OF COMPONENTS
We recommend replacing fans every 40,000 operating hours (with mean temperature of 40 C / 104
F).
HOW TO CLEAN THE UNIT
Open the unit by removing the panel fastening screws and clean it using compressed air.
To clean the heat exchange bank, blow compressed air in the direction opposite the flow of air that
normally passes through it (blow with compressed air at pressures not exceeding 60 psi / 4 bar).
Clean the pipelines inside the heat exchange coil by circulating clean water with detergent
designed to eliminate scale.
The detergent must not contain substances that can corrode copper.
Use of an unsuitable detergent could cause damage to the heat
exchanger. Do not use acid or caustic substances to clean any
part of the exchanger
WARNING
INACTIVITY
There is no problem as long as the liquid is expelled from the heat exchanger circuits and the
pipelines are sealed.
