refrigerants.
Caution
The water heater may only be moved in an upright position. After unpacking, make sure
that the water heater is not damaged.
Caution
Fill the water heater completely before use. Dry firing will damage the water heater.
Caution
The anode protection remains active when the water heater is in OFF mode.
Caution
Water may drip from the discharge pipe of the pressure-relief device. This pipe must be
left open to the atmosphere.
