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 right-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 included in the scope of supply to
operate the air-to-water heat pump.
The heat pump manager is a convenient electronic regulation
and control device. It controls and monitors the entire heating
system based on the external temperature, as well as domestic
hot water preparation and safety systems.
The customer must install the external temperature sensor,
which is included in the scope of supply of 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.

Transport
ATTENTION!
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 heat pump is fixed to the transport
pallet by four transit bolts. These must be removed (only in the
case of LA 17TU and LA 25TU). The basic device can be trans-
ported with a lift truck, a crane, or by means of 3⁄4" pipes fed
through the holes in the base plate. The holes are to be covered
at the installation location using the 8 black dust caps which are
included in the packaging of the device (only in case of LA 17TU
and LA 25TU):
The transport eyebolts must be removed after transportation,
and the sheet metal openings must be closed using the 4 vent
plugs supplied.
After transportation, the transport fastening in the device is to be
removed from both sides of the base.
ATTENTION!
Before start-up, the transport fastening must be removed.

Installation
5.1 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 out-
let direction of the ventilator is perpendicular to the main wind di-
rection 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 values in parentheses are valid for the LA 40TU
The specified dimensions are valid for stand-alone installation
only.
ATTENTION!
Do not restrict or block the area around the air intake or outlet.
ATTENTION!
Observe country-specific building regulations!
ATTENTION!
For installation close to walls the physical influences of the building must
be considered. No windows or doors should be present in the area
surrounding the air outlet of the ventilator.
ATTENTION!
In cases of installation close to a wall, there may be more sediment in the
air inlet and outlet areas due to the air current. The colder outside air
outlet should discharge in such a way as to not increase the heat losses
in heated neighbouring rooms.
ATTENTION!
Installation in a hollow or in an inner courtyard is not permitted because
cooled air collects at ground level and is drawn in again by the heat pump
during lengthy operation.
