Basic device

The basic device consists of a heat pump for indoor installation
wired ready for use with metal casing, switch box and inte-
grated heat pump manager. The refrigeration circuit is "hermet-
ically sealed" and contains the fluorinated refrigerant R410A in-
cluded in the Kyoto protocol. Information on the GWP value
and CO equivalent of the refrigerant can be found in the chap-
2
ter Device information. The refrigerant is CFC-free, non-ozone
depleting and non-combustible.
All components required for the operation of the heat pump are
located in the switch box. An outside temperature sensor in-
cluding fixing accessories and a dirt trap are supplied with the
heat pump. The supply for the supply voltage and the control
voltage must be installed by the customer.
The circulating pumps included in the scope of supply must be
installed in accordance with the hydraulic diagrams (see Cap. 4
on page XXII) or the development documents. The electrical
connection of the circulating pumps must be established in ac-
cordance with Cap. 7.5.3 on page 10.
The control wire of the primary pump (to be provided by the
customer) is to be connected to the control box. When so do-
ing, a motor protecting device is to be installed, if required. The
customer must provide hydraulic components for the well
water circuit.
