Pipe Installation - Nibe UKV 40 Benutzer- Und Installateurhandbuch

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 frost-
proof 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 applic-
able standards.
FILLING
Fill the accumulator tank as follows:
1. Vent the accumulator tank by loosening the connec-
tion (XL8) at the top of the accumulator tank.
2. Fill the vessel through the drain valve.
3. When only water comes out of the connection (XL8)
(an air-water mixture emerges initially), the connec-
tion can be closed and the accumulator tank is filled.
