WARNING Scalding
The water in the DHW tank can be heated to tempera-
tures in excess of 149 °F / 65 °C. There is a risk of scalding
at outlet temperatures in excess of 110 °F / 43 °C.
 Ensure you do not come into contact with the water 

Touching hot components can lead to burns.
When working on hot components, always wear protec-

The pipework connected to the DHW outlet of the appli-
ance can reach temperatures in excess of 149 °F / 65 °C.
WARNING Scalding
The appliance is fi lled with refrigerant at the factory.
In case of leaking refrigerant, avoid coming into contact
with the refrigerant or inhaling the released vapors. Ven-

CAUTION Injury
!
Never place any objects on top of the appliance. If objects
are left on the appliance, noise emissions may increase
due to resulting vibrations, and the objects could fall
and cause injury.
CAUTION
!
To reduce the risk of excessive pressures and tempera-
tures in this water heater, install temperature and pres-
sure protective equipment required by local codes and
no less than a combination temperature and pressure
relief valve certifi ed by a nationally recognized testing
laboratory that maintains periodic inspection of produc-
tion of listed equipment or materials, as meeting the re-
quirements for Relief Valves and Automatic Gas Shutoff
Devices for Hot Water Supply Systems, ANSI Z21.22. This
valve must be marked with a maximum set pressure not
to exceed the marked maximum working pressure of the
water heater. Install the valve into an opening provided
and marked for this purpose in the water heater, and
orient it or provide tubing so that any discharge from
the valve exits only within 6 inches above, or at any
distance below, the structural fl oor, and does not contact
any live electrical part. The discharge opening must not
be blocked or reduced in size under any circumstances.
