NIBE VVM 310Chapter 3 | Indoor module's design10

General pipe connections
Pipe installation must be carried out in accordance with
current norms and directives.
VVM 310 together with a compatible air/water heat
pump (See page 14) 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 dimen-
sioned outdoor temperature, the highest recommended
temperatures are 55 °C on the supply line and 45 °C on
the return line, but VVM 310 can handle up to 65 °C.
NOTE
Equip the product with a safety valve on both
the boiler side and hot water coil.
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 310 as close to the
heat pump as possible for optimum comfort. For further
information about the location of different components,
see section "Installation alternatives" in this manual.
Caution
Ensure that incoming water is clean. When us-
ing a private well, it may be necessary to sup-
plement with an extra water filter.
NOTE
Any high points in the climate system, must be
equipped with air vents.
NOTE
The pipe systems need to be flushed out before
the indoor module is connected so that any
debris cannot damage component parts.
NOTE
Switch (SF1) must not be moved to "" or " "
until VVM 310 has been filled with water.
Otherwise the temperature limiter, thermostat
and the immersion heater etc can be damaged.
Boiler and radiator volumes
H
Internal volume in VVM 310 for
calculating expansion vessel is
250 l. The expansion vessel's
volume must be at least 5 % of
the system's total volume.
Example table
Volume (l)
expansion
vessel
Total volume
(l) (indoor
module and
climate sys-
tem)
25500
35700
501,000
NOTE
Expansion vessel not supplied with the product.
Equip the product with an expansion vessel.
The pre-pressure of the pressure 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.
If the standard initial pressure in the pressure vessel is
not high enough it can be increased by filling via the
valve in the expansion vessel. The expansion vessel's
standard initial pressure must be entered in the check
list on page 6.
Any change in the initial pressure affects the ability of
the expansion vessel to handle the expansion of the
water.

System diagram
VVM 310 consists of hot water coil for hot water heating,
immersion heater, circulation pumps, buffer vessel and
control system. VVM 310 connects to the climate system.
VVM 310 is designed for connection and communication
with a compatible NIBE air/water heat pump, see page
14, which together make up a complete heating install-
ation.
When it is cold outdoors, the air/water heat pump works
with VVM 310, and if the outdoor air temperature falls
below the heat pump stop temperature, all heating is
carried out by VVM 310.
