General
Pipe and ventilation installation has to be performed
according to applicable regulations.
GreenMaster-HP can operate with a return temperature
of up to approx. 58 °C and an outgoing temperature of
65 °C.
GreenMaster-HP is not equipped with external shut off
valves; these should be installed to facilitate any future
servicing. In addition, non-return valves and particle fil-
ters should be installed.
GreenMaster-HP when placed indoors, is equipped with
sheet metal guide connections for exhaust air and extract
air ducts. When located outdoors, GreenMaster-HP is
equipped with sheet metal guide connection for exhaust
air duct and ventilation grille on the extract air side.
Rectangular duct connections are standard on all models
of GreenMaster-HP. Connection dimensions for guide
connections can be found in the relevant unit specifica-
tion for the installed unit.
NOTE
The pipe systems have to be flushed clean be-
fore GreenMaster-HP is connected, to prevent
any contaminants from damaging the compon-
ents.
NOTE
Do not solder directly on the pipes in GreenMas-
ter-HP, because of internal sensors.
Compression ring coupling alternatively pres-
sure connection should be used.
NOTE
The heating system's pipes must be earthed to
prevent a potential difference between them
and the building's protective earth.
NOTE
The potential to clean the air ducts in the future
is required.
Ventilation flow
The ventilation flow must comply with the applicable
national standards.
Connect the property’s common exhaust air duct with
the guide connection to the unit’s filter side.
If flue gas extraction is required, an extra air duct with a
bypass damper has to be installed and connected to the
unit’s prepared fan-in-operation connection.
Adjusting ventilation
In order to achieve the necessary air exchange in the
property, the correct adjustment of the air flow in the
air treatment unit is required.
As soon as possible after installation, the ventilation
should be adjusted to ensure the air flow is set according
to the planned value for the property. Incorrect adjust-
ment can result in impaired function, recovery and
comfort.

GreenMaster-HP consists of cooling module, circulation
pumps, air treatment unit and control system with pos-
sibility of additional heat. GreenMaster-HP is connected
to heating medium circuit.
