Installing optional accessories

4.5.1

Installation of the electric backup heater

(EKBUxx)
INFORMATION
If the ceiling height is low, the storage tank must be tilted to
install the backup heater when empty. This must be done
before any further installation steps.
The Daikin Altherma EHS(X/H) provides the option of installing an
electrical auxiliary heater (backup heater EKBUxx). For example, re-
newable energy can be used as an additional heat source.
INFORMATION
A separate manual containing instructions about installa-
tion and operation is included with this component.
4.5.2 Installation of the external heat generator
connection set
The connection set for external heat generators must be installed to
control an electrical backup heater or another external heat gener-
ator.
1 Open the housing by removing the screw.
2 Remove additional components from the housing (strain relief
clip, cable tie, grommet).
