In order to guarantee a perfect operation of the heat
exchanger, regularly clean the tube bundle. If the surfaces of
the heat exchanger come into contact with salted water, they
may be subjected to biological fouling and to hydrocarbon
deposit which may be present in harbors’ waters.
❏
Remove the tube bundle (3) from the exchanger body
and immerse it for a few minutes in a solution prepared
with water and a degreasing scale-remover detergent,
observing the detergent manufacturer’s directions for
use. The cleansing solution should not damage copper,
brass, aluminum and tin.
❏
Complete tube cleaning by rinsing thoroughly with fresh
water, until detergent residuals are entirely removed.
❏
Reassemble the tube bundle (3) by correctly positioning
spacer (2), sealing rings (4) and covers (1).
❏
Check the zinc anode corrosion level (5); replace the
anode if corrosion exceeds 50% of the volume.
