NIBE™ VVM 320Chapter 1 | Important information6
Transport
VVM 320 should be transported and stored vertically
in a dry place. However, the VVM 320 may be carefully
laid on its back when being moved into a building.
Assembly
■Position VVM 320 on a solid foundation that tolerates
water and the weight of the heat pump. Use the
product's adjustable feet to obtain a horizontal and
stable set-up.
30 - 50 mm
30 - 50 mm
15 - 40 mm
■Because water comes from VVM 320, the area where
the heating pump is located must be equipped with
floor drainage.
Installation area
Leave a free space of 800 mm in front of the product.
All service on VVM 320 can be carried out from the
front.

NIBE™ VVM 320Chapter 3 | Indoor module's design10
General pipe connections
Pipe installation must be carried out in accordance with
current norms and directives.
VVM 320 together with air/water heat pumps F2030-
7 / F2030-9 or F2040-8 / F2040-12, F2120-8 / F2120-
12 / F2120-16 make up a complete installation for
heating and hot water.
The system requires the radiator circuit to be designed
for a low temperature heating medium. At lowest di-
mensioned outdoor temperature, the highest recom-
mended temperatures are 55 °C on the supply line and
45 °C on the return line, but VVM 320 can handle up
to 65 °C.
Overflow water from the safety valve goes via overflow
cups to a drain so that hot water splashes cannot cause
injury. The entire length of the overflow water pipe
must be inclined to prevent water pockets and must
also be frost proof.
NIBE recommends installing VVM 320 as close to the
heat pump as possible for optimum comfort. For further
information about the location of different compon-
ents, see section "Installation alternatives" in this
manual.
NOTE
Any high points in the climate system, must
be equipped with air vents.
NOTE
The pipe systems need to be flushed out be-
fore the indoor module is connected so that
any debris cannot damage component parts.
NOTE
Switch (SF1) must not be moved to "" or " "
until VVM 320 has been filled with water.
Otherwise the temperature limiter, thermostat
and the immersion heater etc can be dam-
aged.
Boiler and radiator volumes
H
VVM 320 is equipped with a
pressure expansion vessel of
10 litres.
The pre-pressure of the pres-
sure expansion vessel must
be dimensioned according to
the maximum height (H)
between the vessel and the
highest positioned radiator,
see figure. A pre-pressure of
0.5 bar (5 mvp) means a
maximum permitted height
difference of 5 m.
The maximum system volume
excluding the boiler is 220
litres at the above pre-pres-
sure.

System diagram
VVM 320 consists of water heater with charge coil, ex-
pansion vessel, safety valve, filler valve, immersion
heater, circulation pumps, buffer vessel and control
system. VVM 320 is connected to the climate system.
VVM 320 is designed for connection and communica-
tion with F2030 / F2040 / F2120, which together make
up a complete heating installation.
When it is cold outdoors F2030 / F2040 / F2120 works
with VVM 320 and if the outdoor air temperature falls
below the heat pump stop temperature, all heating is
carried out by VVM 320.

below.
Further option information is available at www.nibe.eu
and in the respective assembly instructions for the ac-
cessories used. See page 61 for a list of the accessories
that can be used with VVM 320.
The indoor module can be supplemented with an
electric water heater, if a hot tub or other significant
consumer of hot water is installed. A mixing valve is
then installed on outgoing hot water from the heater.
Water heater with immersion heater
If the valve connector is to be installed externally,
moved out or separated, it must be replaced with a
separable connector Ø 22 mm.
