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 stand-
ards.
Volume increase as well as reduction of heat
spikes
A UKV 100 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 100 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.

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 return
line (XL2).
The system where UKV 100 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 frost-
proof and well supported. The mouth of the overflow pipe
must be visible and not placed close to electrical compon-
ents.
Ensure that incoming water is clean.
If uncertain, contact a plumber alternatively see applicable
standards.
FILLING
Fill the accumulator tank as follows:
1. Vent the accumulator tank by loosening the connection
(XL1) at the top of the accumulator tank.
2. Fill the vessel through the drain valve.
3. When only water comes out of the connection (XL1) (an
air-water mixture emerges initially), the connection can
be closed and the accumulator tank is filled.
