USE AND MAINTENANCE
The unit is ready for use once it has been connected to water and electricity. Correct
installation and use assures faultless performance of the heating pump with little or
no servicing or maintenance.
If there is danger of freezing, discharge the water from the hot water tank. Open
the hot water tap, connected to hot water tank. Let the water pour our through the
discharge valve on the inlet hose.
The exterior of the water heater may be cleaned with a mild detergent solution.
Do not use solvents and abrasive cleaning agents. If dust deposits on the unit,
use a vacuum cleaner and remove the dust, otherwise the operation of the unit is
impaired.
