Pipe Installation - Nibe VPA 200/70 Benutzer- Und Installateurhandbuch

Pipe installation

Pipe installation must be carried out in accordance with
current norms and directives.
The water heater must be fitted with the requisite valves,
such as a safety valve, shut-off valve, non-return valve
and vacuum valve.
The water heater must be provided with a mixer valve,
which limits the temperature of outgoing hot water to
60 °C. If this valve is not fitted, some other measure must
be taken to prevent the risk of scalding.
Internal support bushes must be fitted when a plastic or
annealed copper pipe is used. An overflow pipe must be
routed from the safety valve to a suitable drain. The
overflow pipe must be the same size as the safety valve.
Route the overflow pipe from the safety valve, sloping
along its entire length and ensure that it is frost proof.
The mouth of the overflow pipe must be visible and not
placed close to electrical components.
The water heater is equipped with a docking connection
for connection to heat pump (max 12 kW) or other ex-
ternal heat source.

Filling
The water heater
The water heater is filled by first opening a hot water
tap in the system and then opening the shut-off valve
for incoming cold water. This valve must then be fully
open during operation. The hot water tap can only be
shut off when the water heater is filled, which is when
only water comes out of the tap (initially an air-water
mixture comes out of the tap).
The climate system
When filling the climate system the double-jacketed
space must be vented by opening the air nipple.. The air
nipple may only be closed when water starts coming out
of the air hole.
