990300008 BVVP topmodul drain
Water trap. Min. 60 mm
of standing water
Condensate drain, Ø 19 mm
connection (3/4”)
5.3 Water connections
The water connections are located on the left hand side of the HPM heat pump
• Ø15 cold water inlet, lowest connection
• Ø15 hot water outlet, highest connection
The maximum working pressure is 1.0 MPa (10 bar) and the maximum working temperature is
65°C.
A fixed speed circulation shall be installed in order to tranfer the heat from the heat pump to the
water tank. Flow rates between 200-600 l/hr shall be ensured and it is recommended to install
the circulation pump on the HPM water inlet pipe.
Dirt in the pipe work must be avoided. After installation of the external pipes flush if required
before connection of the domestic hot water heat pump.
When installing the pipes please ensure that the pipe connections are not excessively stressed.
Use a pipe wrench to relax torque forces on the pipe connections!
5.4 Connection of condensate drain
While the METROAIR AQUA HPM is running, condensate will form, which is to be discharged
to the sewage drain via the condensate drain pipein the bottom of the unit. The quantity of
condensate depends upon the humidity of the air fed to the METROAIR AQUA.
The condensate connecting branch must be equipped with an air tight water trap and run to a
drain. The water trap must contain a standing water column of at least 60 mm.
5.5 Air intake, air exhaust and connections
The inlet air must not be polluted with aggressive components (ammonia, sulphur, chlorine etc.)
as components parts of the heat pump unit may be damaged. The air also needs to be free of
dust and other particles.
Inlet and outlet ducts must be made of rigid smooth pipes to minimize pressure losses. Please
take into account the fan working pressure and the ducts pressure losses during dimensioning
of the duct system (see technical data).
The two connections to the heat pump are Ø 160 m.
It is advised to install the air ducts near the heat pump, levelled or with a slight slope away from
the air in- and outlet to avoid ingress of condensed water from the duct system to the heat
pump.
When air ducts are connected to the outside of a building, a low resistance non return flap
should be installed to ensure that no cold air is entering the room during winter times when the
heat pump is not operating.
Neglecting to install a drain
trap can lead to water damage
or damage to METROAIR AQUA
HPM. If the drain trap is not in-
stalled correctly the product war-
ranty is not valid.
The METROAIR AQUA HPM
must only be started with the water
circuet filled
