The serial number can be found on top of the product.
Caution Always give the product’s serial number when reporting a fault.
RECOVERY
Leave the disposal of the packaging to the installer who installed the product
or to special waste stations. Do not dispose of used products with normal
household waste. It must be disposed of at a special waste station or dealer
who provides this type of service.
Improper disposal of the product by the user results in administrative
penalties in accordance with current legislation.
INSPECTION OF THE INSTALLATION
Current regulations require the heating installation to be inspected before it is commissioned. The inspection must be carried out by a suitably qualified person.

For the User
MAINTENANCE
The safety valve in the system where the accumulator tank is installed must be
inspected regularly (about four times a year) to prevent blockages.
To inspect the valve, open the safety valve manually and check that water
flows through the overflow pipe. If this does not happen then the safety valve
is defective and must be replaced.
SERVICE
For service, contact the installer. Serial number (PZ3) (14 digits) and installation date should always be stated. Only replacement parts supplied by NIBE may be used.
For the Installer
GENERAL
UKV 40 has several different areas of use.
UKV 40 can be used during external control of the heating system. The heat
pump then charges UKV 40 with floating or fixed condensing. The external
control function controls the heat distribution from UKV 40 to the consumer.
If the flow to the heating system can be restricted using radiator
thermostats, for example, install a UKV 40 as an intermediate tank. This
ensures a secure flow for the heat pump.
UKV 40 also allows a greater flow to the heating system than across the heat pump.
In some installations, so-called heating clicks occur as a result of movements during changes in temperature. To eliminate temporary changes in temperature, and thereby prevent heating clicks, install a UKV 40 after the heating installation.
UKV 40 can also be used to increase the system volume and thereby prevent malfunctions.
The accumulator tank consists of a condensation-insulated steel vessel with polyurethane insulation. Outer cladding in white, powder-coated sheet metal with ends of durable plastic.
The accumulator tank is designed and manufactured for a maximum cut-off pressure of 6 bar. The working temperature is +4 to +95 °C.
TRANSPORT
UKV 40 should be transported and stored in the dry.
ASSEMBLY
The accumulator tank must be installed in a dry area at a temperature that does not drop below 0 °C (frost-free).
MOUNTING
UKV 40 has to be installed vertically suspended on the wall. First install the enclosed mounting bracket on the wall, then suspend UKV 40 from the bracket.
SUPPLIED COMPONENTS
Suspension bracket.

INSTALLATION
All connections (including connections or holes that are not used) must be insulated to minimise energy losses.
DOCKINGS
NOTE These are outline diagrams. Actual installations must be planned according to applicable standards.
Volume increase as well as reduction of heat spikes
A UKV 40 is installed as a volume increaser in those cases where the system volume in the climate system is below the minimum recommended volume for the heat pump. Volume and flow increaser and reduction in heat spikes
A UKV 40 is installed as a volume and flow increaser in those cases where the system volume in the climate system is below the minimum recommended volume for the heat pump and/or the flow is restricted without control.
Volume increase as well as reduction of heat spikes
A UKV 40 is installed as a volume increaser in those cases where the system volume in the climate system is below the minimum recommended volume for the heat pump.
PIPE INSTALLATION
Pipe installation must be carried out in accordance with current norms and
directives.
The drain valve is installed on the heating system’s supply line (XL1).
The system where UKV 40 is installed must be supplied with a safety valve of
max. 6 bar (0.6 MPa).
The overflow pipe must be the same size as the safety valve’s. Route the
overflow pipe from the safety valve, sloping along its entire length, and
ensure that it is frostproof and well supported. The mouth of the overflow
pipe must be visible and not placed close to electrical components. Ensure
that incoming water is clean.
If uncertain, contact a plumber alternatively see applicable standards.
FILLING
Fill the accumulator tank as follows:
- Vent the accumulator tank by loosening the connection (XL8) at the top of the accumulator tank.
- Fill the vessel through the drain valve.
- When only water comes out of the connection (XL8) (an air-water mixture emerges initially), the connection can be closed and the accumulator tank is filled.
