Appliance description

The appliance is a DHW heat pump in a hydraulic split design. It
can be connected in various ways with an external DHW cylinder
(see chapters "Water connection / Connection to the DHW cylinder"
and "Specification / Hydraulic connection diagram").
Note
The appliance is suitable for DHW cylinders up to 500 l
capacity.
f The application for 500 l DHW cylinders must be f
checked in advance by the system installer.
The heat pump has been designed to provide enough domestic hot
water for a household of 5 people. The maximum volume of DHW
cylinders that can be connected is therefore limited by the thermal
output of the appliance and the expected maximum heat-up times.
f When installing the appliance, check whether any installed f
DHW cylinders are large enough to meet the short-term DHW
demand.
The thermal output of the heat pump depends on heat source
temperature (supply air) and set DHW value.
f To calculate the appliance output at different intake tem- f
peratures and the corresponding heat-up times, please use
the output diagram in the chapter "Specification / Heating
output").
f Observe the minimum volume of the installation room and f
the heat-up time during normal domestic use when com-
bined with a 300 l cylinder (see chapter "Specification / Data
table").

f In recirculation air mode, when selecting the type and size f
of installation room, ensure that energy use is compensated
over a period of 24 hours and the lower application limit of
the appliance is not undershot.
Please also observe the following factors: Expected runtime
per day, the resulting cooling energy, existing heat sources
in the installation room (e.g. freezer, tumble dryer, central
heating), heat flux from adjoining rooms.
