Normal maintenance

NOTICE: THE DHE UNITS DO NOT CONTAIN ANY
!
PARTS SERVICEABLE BY THE LAY PERSON. IN CASE
OF MALFUNCTION PLEASE CONTACT A LICENSED
PLUMBER OR ELECTRICIAN.
Aqua Power DHE tankless water heaters are designed for a very
long service life. Actual life expectancy will vary with water
quality and use. The unit itself does not require any regular
maintenance. However, to ensure consistent water flow, it is
recommended to periodically remove scale and dirt that may
build up at the aerator of the faucet(s), the filter screen in the
unit, or in the shower head.
