3 - DESCRIPTION
A fan is provided to lower the temperature inside the sound
insulating enclosure. This fan must be installed by the client and
connected to a 230 V power supply. To improve efficiency, it makes
sense to fit a thermostat (not part of the standard delivery) for
starting and stopping the fans. The thermostat should be installed
inside the sound insulating enclosure and should start the fan at
temperatures ≥30°C. Assembly instructions are supplied with the
sound insulating enclosure.
Assembly requires 2 persons (in particular of the roof elements).
Unless ordered separately, the sound insulating enclosure is not
installed by CARRIER.
Because the sound insulating enclosure rests on the floor, the
floor around the heat pump must be level and must not contain
elements such as pipes, profiles, etc. in the contact area of the
soundproofing enclosure.
The pipes to the heat exchanger connections of the heat pump
must be routed in a straight line. Never use bends inside the sound
insulating enclosure. The minimum length for a straight pipe
section is given in the "Dimensions sheet with sound insulating
enclosure", which is available from CARRIER on request. Ensure
that no pipes, profiles, etc., interfere with the sound insulating
enclosure.
3.3 - Pipework
3.3.1 - General
3.3.1.1 - Refrigerant lines
The following refrigerant lines are installed inside the heat pump:
■ Suction gas line (SL)
■ Pressure line (DL)
■ Liquid line (FL)
■ Economiser line (EL)
■ Oil line (ÖL)
These are made from copper or steel, depending on their diameter
and application. The lines are intended only for conveying the
refrigerant within the heat pump.
3.3.2 - Operating media
The pipelines listed under 3.4.1.1 are filled with the fluid indicated
on the respective type plate and must only be filled with this fluid.
Use of any other substance immediately voids the CARRIER
warranty and any claims for damage.
3.3.3 - Application range
The required ambient conditions are described in section 4.3
(installation location).
The maximum pressure as well as the maximum and minimum
temperature are also specified on the type plate and must never
be exceeded.

3.3.4 - Mechanical stress
Beyond the intended use, the installed lines must not be exposed
to any additional mechanical or thermal loads.
Mechanical loads can result in pipework deformation, stress cracks
in pipe components and joints, or pipes pulling off, resulting in
leakages or even a total failure of the heat pump.
The above pipes must not be welded or brazed without approval
from CARRIER. Any welding or brazing work by third parties voids
CARRIER's warranty as well as the CE Declaration of Conformity.
No mechanical work must be carried out on the above pipes
without approval from CARRIER. Any mechanical work by third
parties voids CARRIER's warranty as well as the CE Declaration
of Conformity.
Screws designed to attach the refrigerant lines to the heat pump
must not be undone.
Screws in the filter dryer cover must not be undone.
Shut-off valves must not be operated.
Inserts in Schrader valves must not be operated or unscrewed.
Only CARRIER customer service may remove or dismantle
pipework. Removal by third parties is not permissible and
immediately voids CARRIER's warranty.
In the event of leakage, please contact CARRIER immediately.
Leakages may only be repaired by CARRIER customer service.
DANGER! Escaping refrigerant can cause severe burns and
oxygen displacement!
CAUTION! Escaping refrigerant can result in a total failure of
the heat pump.
3.3.5 - Insulation
Lines are fitted with thermal insulation. This must not be damaged.
Damaged insulation can result in excessive heat transfer (heat
loss) to the environment, reduction of the COP (coefficient of
performance) and condensate formation on cold pipes, resulting
in corrosion.
The insulation is classified D-s3, d0 according to EN 13501-1.
