7.16 Tightness test on the refrigerant circuit
Heat pump refrigerant circuits containing a refrigerant with a CO
2
equivalent of 5 t or more must be tested regularly for tightness in
accordance with EU Regulation No. 517/2014. In the case of her-
metically sealed refrigerant circuits, this regular testing is required for
a CO
2
equivalent of 10 t or more.
The intervals at which the refrigerant circuits will need to be tested
depend on the level of CO
2
equivalent. If leak detection facilities are
available on site, the test intervals are extended.
The Vitocal 200-A and Vitocal 222-A heat pumps have hermetically
sealed refrigerant circuits. The CO
2
equivalent is below 10 t for all
appliances.
A regular tightness test of the refrigerant circuit is therefore
not
required.
7.17 Intended use
The appliance is only intended to be installed and operated in sealed
unvented heating systems that comply with EN 12828, with due
attention paid to the associated installation, service and operating
instructions.
Depending on the version, the appliance can only be used for the
following purposes:
■ Central heating
■ Central cooling
■ DHW heating
The range of functions can be extended with additional components
and accessories.
Intended use presupposes that a fixed installation in conjunction with
permissible, system-specific components has been carried out.
Commercial or industrial usage for a purpose other than central
heating/cooling or DHW heating shall be deemed inappropriate.
Incorrect usage or operation of the appliance (e.g. the appliance
being opened by the system user) is prohibited and will result in an
exclusion of liability. Incorrect usage also occurs if the components
in the heating system are modified from their intended function.
Note
The appliance is intended exclusively for domestic or semi-domestic
use, i.e. even users who have not had any instruction are able to
operate the appliance safely.
