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.

Transport

ATTENTION!
When transporting the heat pump, ensure that it is not tilted
more than 45° (in any direction).
A pallet should be used to transport the heat pump to its final
installation location. The heat pump is fixed to the transport pal-
let by four transit bolts. These must be removed (only in the
case of LA 25TU-2). The basic device can be transported 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 25TU-2:
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.
