3 Installation
Location of the Tank
Buffer tanks of UKV Series should be installed in a
dry area, protected against temperatures below 0°C
(e.g. in the basement, boiler room, etc.). Location and
manner of installation must ensure trouble-free main-
tenance and servicing of the unit in the future.
To suspend the unit, use the auxiliary brackets at-
tached to the product. With ø12 dowels and ø8 screws
(included), secure the brackets horizontally to a suita-
bly hard wall, i.e. made of concrete, solid bricks, etc.
When suspending on the walls of lower carrying ca-
pacity, e.g. made of gypsum, hollow bricks, etc., use
a different kind of dowels and screws to ensure stable
mounting of the unit. After mounting the bracket, hang
the unit on the main bracket.
The manufacturer shall not be liable for damages re-
sulting from improper installation of the tank.

Installation Requirements
CAUTION
Installation and commissioning of the buffer
tank shall only be done by appropriately qu-
alifi ed installer. The installer should inform the
user of the functions of the product and provi-
de the necessary information on its safe use.
Buffer tanks Series UKV can be connected to open or
closed central heating systems. Pressure in the C/H
system may not exceed the max operating tempera-
ture of the unit (for the allowable operating parame-
ters of the units, see Table 2 Technical data.) Connect
the buffer tank in accordance with the installation

DESCRIPTION:
1. Buffer tank
2. Cut-off valve
3. Drain valve
4. Opened Expansion tank
Closed System
Buffer tanks Series UKV can be connected to a closed
C/H system in accordance with relevant regulations
and standards.
Buffer tank operating in a closed circuit must be
equipped with correctly dimensioned safety valve
(preferably in the heating medium return line to the
heating source), with blow-off pressure not exceeding
the max operating pressure of the unit (for the max
operating pressures of the units, see Table 1 Techni-
cal data.) Some amount of the heating medium can
leak from the safety valve during normal operation,
therefore, you should install a drain line in the safety
valve, allowing safe drain of the heating medium to
the sewerage or drain grate. Safety valve drain line
should be installed with a decline, in an environment
free of freezing and remain open to the atmosphere.
NIBE is not responsible for fl ooding the room through
the safety valve.
