Pipe Installation - Nibe UKV 500 Benutzer- Und Installateurhandbuch

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 re-
turn line (XL9).
The system where UKV 500 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.

tially an air-water mixture comes out of the valve),
the vent valve can be closed the accumulator tank
is filled.
