7 Service and maintenance
7.1 General
Regular inspection and maintenance of the HPSU compact re-
duces energy consumption and ensures a long life and smooth
operation.
Legal requirements
According to the F-Gases Directive (EC) No. 842/2006 Article 3,
replaced on 01.01.2015 by (EC) No. 517/2014 Articles 3 and 4,
Operators (or Owners) must perform regular maintenance on
their fixed cooling systems, check impermeability and have any
leaks repaired immediately.
All installation, maintenance and repair work on the cooling circuit
mu
st be documented e.g. in the operating manual.
Operators of ROTEX heat pump systems are subject to the
following obligations:
Ɣ With a system coolant total filling quantity of 3 kg – 30 kg
or from 6 kg in hermetic systems and from 01.01.2017 with a
total filling quantity of 5-50 t CO
2
-equivalent or from 10 t CO
2
-
equivalent in hermetic systems:
Î Inspections carried out by certified personnel at intervals
of no more than 12 months and documentation of the
work performed in accordance with valid regulations. This
documentation must be retained for at least 5 years.

RISK OF ENVIRONMENTAL DAMAGE!
Important information regarding the coolant used.
The complete heat pump system contains refrigerant
with fluorinated greenhouse gases which damage the
environment if released.
Coolant type: R410A
GWP* value: 2087,5
* GWP = Global Warning Potential
Ɣ Fill in the total coolant filling quantity on the
supplied lable on the heat pump exterior unit (for
information consult the installation instructions for
the heat pump exterior unit).
Ɣ Never all
ow coolant to be released into the atmos-
phere - always suction it off and recycle using a
suitable recycling device.
Have the inspection and maintenance carried out by
au
thorised and trained HVAC engineers once a year,
ideally before the heating period. This can prevent
faults during the heating period.
ROTEX recommends an inspection and maintenance
contract to ensure regular inspection and maintenance.
The European statutory investigation period applies for
heat pumps from
a total system coolant filling quantity
of 3 kg or, as of 01.01.2017 from a to
tal filling quantity
of 5 t CO
2
-equivalent (in the case of R410A from
2.4 kg).
ROTEX nonetheless recommends the conclusion of a
maintenance contract, including documentation of the
work carried out in the operating manual in order to pre-
serve the right to guarantee, including
for systems for
which there is not legal obligation to monitor imperme-
ability.
Certified people are those who have proof of expertise
for the European Community for work on stationary
refrigeration systems (heat pumps) and air conditioning
systems, according to the F-Gases Directive
(EC)
303/2008.
