1.1 Floor load
1.2 Working clearance
1.3 Packaging
1.4 Disposal
Allow for the indirect water heaters weight and the maximum floor load; refer to the table
(1.5 "General specifications").
For access to the indirect water heater, it is recommended that the following clearances
are observed:
•around the anode connection: 100 cm.
•around the vessel: 50 cm.
•top of the vessel: 50 cm
Note
When installing the indirect water heater, be aware that any leakage from the tank and/or
connections can cause damage to the immediate environment or floors below the level
of the boiler room. If this is the case, the indirect water heater should be installed above
a waste water drain or in a suitable metal leak tray.
The leak tray must have an appropriate waste water drain and must be at least 5 cm
deep with a length and width at least 5 cm greater than the diameter of the indirect water
heater.
The packaging prevents damage to the appliance during transport. The
packaging material chosen is environmentally friendly, recyclable and
relatively easy to dispose of in an environmentally aware way.
Old end-of-life appliances contain materials that need to be recycled. When disposing of
old devices that have reached the end of their service life, you should
take account of local legislation relating to waste disposal.
You must therefore never dispose of your old appliance together with
regular waste, but should and it into a municipal waste collection depot for
electrical and electronic equipment. Ask your dealer/installation engineer
for advice if necessary. The old appliance must be stored out of reach of
children.
