Benchmark places responsibilities on both manufactur-
ers and installers. The purpose is to ensure that custom-
ers are provided with the correct equipment for their
needs, that it is installed, commissioned and serviced
in accordance with the manufacturers instructions by
competent persons and that it meets the requirements
of the appropriate Building Regulations. The Benchmark
Checklist can be used to demonstrate compliance with
Building Regulations and should be provided to the
customer for future reference.
Installers are required to carry out the installation, com-
missioning and servicing work in accordance with the
Benchmark Code of practice which is available from the
Heating and Hotwater Industry Council who manage
and promote the Scheme. Visit centralheating.co.uk for
information.

General
Pipe installation must be carried out in accordance with
current regulations. See manual for compatible NIBE
air/water heat pump for installation of the heat pump.
NOTE
The heating medium side and the domestic
hot water side must be fitted with the neces-
sary safety equipment in accordance with the
applicable regulations.
The pipe dimension should not be less than the recom-
mended pipe diameter according to the table. However,
each system must be dimensioned individually to man-
age the recommended system flows.
MINIMUM SYSTEM FLOWS
The installation must be dimensioned at least to manage
the minimum defrosting flow at 100% pump operation,
see table.

NOTE
An undersized system can result in damage to
the machine and lead to malfunctions.
VVM S320 together with a compatible air/water heat
pump (See section Outdoor modules) constitutes 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 dimen-
sioned outdoor temperature, the highest recommended
temperatures are 55 °C on the supply line and 45 °C on
the return line, but VVM S320 can handle up to 70 °C.
Overflow water from the safety valve goes via an over-
flow cup 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. The mouth of the overflow
water pipe must be visible and not located close to
electrical components.
NIBE recommends installing VVM S320 as close to the
heat pump as possible for the optimum comfort. For
further information about the location of various compon-
ents, see section "Installation alternatives" in this
manual.
Caution
Ensure that incoming water is clean. When
using a private well, it may be necessary to
supplement with an extra water filter.
NIBE VVM S320Chapter 4 | Pipe connections16
4 Pipe connections

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
Do not start the system before filling up with
water. Components in the system could be
damaged.
NOTE
This installation is subject to building regulation
approval, notify the local Authority of intention
to install.
NOTE
Use only manufacturer’s recommended replace-
ment parts.
Waste water from the collection tray and from the safety
valves is led by a non-pressurised overflow pipe to the
drain so that hot water cannot cause damage. The
mouth of the overflow pipe must be visible and not
placed close to electrical components. In addition, the
opening of the overflow pipe (tundish), drain valves and
motorised valves should also be positioned away from
all electrical components. This is the only thing the non-
pressurised overflow pipe may be used for. Even over-
flow pipes from tundish connected to the expansion
relief valve must be connected to the drain in the same
way.
Please note that the connection of the T&P-valve should
not be used for any other purpose.
Valves may not be positioned between the expansion
valve and the vessel.
Overflow pipes from tundish must be routed with a fall
of at least 300 mm, before bends or angles in the pipe-
work (see image).

HARD WATER AREAS
Usually, there should not be a problem in installing
VVM S320 in areas of hard water as the operating tem-
perature is 50–60 °C.
CLEANING THE CLIMATE SYSTEM
When the water heater and the climate system have
been filled with water, VVM S320 must operate at
maximum normal temperature for at least one hour.
Thereafter the system must be drained of water and
refilled.
17Chapter 4 | Pipe connectionsNIBE VVM S320

Before installing the heat pump in an existing system,
it is important that the system is properly flushed
through.
Even if the heat pump is to be installed in a new system,
the heat pump and system should be flushed.
NOTE
Ensure that cleaning agent has been removed
from the entire system before adding inhibitor.
After flushing an inhibitor should be used for long-term
anti-corrosion protection.
NIBE Energy Systems Limited recommends water
treatments (supplied by e.g. Fernox and Sentinel) spe-
cifically designed for heat pumps.
SYSTEM VOLUME
H
VVM S320 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 max-
imum permitted height differ-
ence of 5 m.
The maximum system volume excluding the boiler is
220 litres at the above pre-pressure.

SYSTEM DIAGRAM
VVM S320 consists of water heater with charge coil,
expansion vessel, safety valve, filler valve, immersion
heater, circulation pumps, buffer vessel and control
system. VVM S320 connects to the climate system. *
VVM S320 is directly adapted for connection and com-
munication with a compatible NIBE air/water heat pump,
see section "Outdoor modules", and together they con-
stitute a complete heating installation.
When it is cold outdoors, the air/water heat pump works
with VVM S320, and if the outdoor air temperature falls
below the heat pump’s stop temperature, all heating is
carried out by VVM S320.
