1. General description
1.1. General information
By purchasing this system you have decided in favor
of a modern and cost-effective heating system. Con-
tinuous quality controls and improvements as well as
functional checks at our production facilities guaran-
tee technically error-free equipment.
Please read this documentation carefully. It con-
tains important instructions for a correct installa-
tion, for the reliable and an economical operation
of the system.
1.2. Safety instructions
Installation and maintenance operations can be as-
sociated with dangers resulting from high system
pressures, high temperatures and voltaged parts.
Heat pumps may only be installed by competent spe-
cialist and exclusively put into operation by a cus-
tomer service specialist trained for that purpose by
IDM-Energiesysteme GmbH.
If maintenance work is being done on the heat pump,
disconnect the system and ensure that it is volt-free
and provided with a safeguard to prevent unintention-
al restarting. Furthermore all safety instructions in the
respective documentation or on instruction plates af-
fi
xed to the heat pump itself resp. all other pertinent
safety regulations shall be observed.
1.3. Transport and storage
In transporting the heat pump ensure that it is never
tilted by more than 30°. Do not remove the transport
packaging until the heat pump has reached its instal-
lation location. Heat pump components must not be
stored outside. Heat pumps must not be stored in
humid rooms or dusty environments. The transport
fi
xtures as described in the following assembly
instructions are used to transport the heat pump
manually. The transport
fi
xtures must not be used for
transporting the components with a crane or similar
hoisting equipment.
1.4. Sound emission
TERRA heat pumps run extremely smoothly due
to their construction. It is nevertheless important to
ensure that the heating room is located beyond the
noise-sensitive living area and furnished with a well-
closing door.
1.5. Construction drying and fl oating screed heating
Floor screed heating with the heat pump can only
take place if the air suction temperature continuously
lies over +5°C, as otherwise a correct defrosting of
the air evaporator cannot be guaranteed due to the
low
fl
ow temperatures. Otherwise the
fl
oor screed
has to be heated with the electric heating element!
1.6. Service and maintenance
Regular maintenance as well as an inspection and
maintenance of all important system components
guarantees a reliable and low-price operation of the
system in the long term. We recommend you to sign
a maintenance contract with your competent cus-
tomer service.
1.7. Cleaning
If necessary, the TERRA heat pump can be cleaned
using a humid cloth. The use of cleaning agents is
not recommended.
The air vent package in the air heat exchanger
has to be inspected regularly and cleared of any im-
purities (e.g. foliage,...), if necessary.
To avoid water damage, the condensation bin and the
condensation run-off tube must be cleaned regularly.
