4.1 Connecting Flanges

The use of flat-sealing connecting flanges allows the unit, as an
option, to be connected by means of flanges.
4.2 External four-way reversing
valve, Water circuit side
The external four-way reversing valve (Y12) enables optimised
heating and cooling operation of the reversible water-to-water
heat pump. The reversal of the flow direction ensures an opti-
mum flow through the heat exchanger on the secondary side,
both in heating operation and in the opposite direction in cooling
operation. The electrical actuator required for automatic switch-
ing is controlled by the heat pump manager. (Max. permissible
switching current 2A).
If the external four-way reversing valve is not used, the heat out-
puts and the COPs are reduced as specified in the device infor-
mation. With heating-only operation without an external four-way
valve, the hydraulic connection should be carried out such that
the heat exchanger is loaded in the opposite direction (observe
note in section 7.2 „Connection on heating and hot water side").

The external four-way reversing valve with a set time of max. 60
seconds, which is available as special accessory, ensures
switching of the water flow over the complete range of operating
temperatures without any mixing losses.
The hydraulic and electrical circuit diagrams in the appendix
show the basic design. Detailed installation instructions are pro-
vided with the four-way reversing valve.

For the transport by means of a hand truck or boiler trolley, posi-
tion the latter under the front end of the unit below the transport
security device.
For transport on a level surface, the unit can be lifted from the
rear or from the front by means of a lift truck or forklift. In this
case, the transport securing device is not imperative.
The heat pump must not be tilted more than max. 45° (in either direction).
After the transport, the transport securing device is to be re-
moved on either side at the bottom of the unit.
The transport securing device is to be removed prior to commissioning.
To remove the panelling, open the individual covers by unscrew-
ing the respective turn-lock fasteners and then gently tilting the
covers away from the device. Then lift them up out of the mount-
ings.
