3.2 Switch box

The switch box is located in the heat pump. It can be swung out
after removing the lower front cover and loosening the fastening
screw located in the upper left-hand corner.
The switch box contains the supply connection terminals as well
the power contactors and the soft starter unit.
The plug connectors for the control line are located on the switch
box panel near the pivotal point.

3.3 Heat pump manager

Use the heat pump manager for reversible heat pumps included
in the scope of supply to operate the reversible air-to-water heat
pump.
The heat pump manager is a convenient electronic regulation
and control device. It controls and monitors the entire heating
and cooling system on the basis of the external temperature,
including domestic hot water preparation and safety systems.
The customer must install the external temperature sensor,
which is included with the unit heat pump and manager together
with the necessary fixing accessories.
The enclosed operating instructions describe the function and
use of the heat pump manager.

Accessories

4.1 Electrical connection line

The electrical connection line is an accessory required for the
functioning of the system. It connects the heat pump to the heat
pump manager and it is available in various lengths.
4.2 External four-way reversing
valve
The external four-way reversing valve (Y12) enables optimised
heating and cooling operation of the reversible air-to-water heat
pump. The reversal of the flow direction ensures an optimum flow
through the heat exchanger in the heat pump in heating
operation as well as in the opposite direction in cooling operation.
The electrical actuator required for the automatic switching is
controlled by the heat pump manager. (Max. permissible
switching current 2A).
If the external four-way reversing valve is not used, the heat
outputs and the COPs are reduced as specified in the device
information. 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 side").
The external four-way reversing valve with a set time of max. 30
seconds, which is available as special accessory, ensures
switching of the water flow over the complete range of operating
temperatures without any mixing losses. Provision of a dirt trap
with a mesh size of 0.6 mm is recommended at a suitable
location.
The hydraulic and electrical circuit diagrams in the appendix
show the basic design. Detailed installation instructions are
provided with the four-way reversing valve.

When transporting the heat pump, ensure that it is not tilted more than
45° (in any direction).
A wooden pallet should be used to transport the heat pump to its
final installation location. The basic device can be transported
either with a lift truck or a crane. The transport eyebolts must be
removed after crane transport and the sheet metal openings
closed with the closing plugs supplied.
After transportation, the transport fastening in the device is to be
removed from both sides of the base.
Before start-up, the transport fastening must be removed.

6.1 General

The device should always be installed on a permanently smooth,
even and horizontal surface. The entire frame should lie directly
on the ground to ensure a good soundproof seal and to prevent
the water-bearing components from becoming too cold. If this is
not the case, additional insulation measures may be necessary.
Furthermore, the heat pump should be set up so that the air
outlet direction of the ventilator is perpendicular to the main wind
direction to allow unrestricted defrosting of the evaporator. It
must be possible to carry out maintenance work without
hindrance. This is ensured when observing the distances to solid
walls as shown in the figure.
The specified dimensions are valid for stand-alone installation
only.
