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 100 has several different areas of use.
UKV 100 can be used during external control of the
heating system. The heat pump then charges UKV 100
with floating or fixed condensing. The external control
function controls the heat distribution from UKV 100 to
the consumer.
If the flow to the heating system can be restricted using
radiator thermostats, for example, install a UKV 100 as
an intermediate tank. This ensures a secure flow for the
heat pump.
UKV 100 also allows a greater flow to the heating sys-
tem 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 100 after
the heating installation.
UKV 100 can also be used to increase the system
volume and thereby prevent malfunctions.
The accumulator tank consists of a condensation-insu-
lated 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 100 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 100 has to be installed vertically suspended on the
wall. First install the enclosed mounting bracket on the
wall, then suspend UKV 100 from the bracket.
