DEPLOYMENT
In order to deploy buffer tanks, the
following conditions should be en-
sured:
•
Ensure intact and stable flooring,
so that it can keep the total
weight of the buffer tank filled up
with water.
•
Horizontal flat flooring, to guar-
antee absolutely vertical standing
of the unit. Vertical standing
should be performed with ade-
quately secure support of the
legs.
•
The buffer should be deployed
only in a
against frost. In case of frost
danger, the buffer tank should be
emptied.
•
The unit should be installed in a
way that its distance from the
wall is at least 50 mm.
•
Due to any possible system ex-
pansion, a distance of at least 70
cm should be guaranteed be-
tween 6/4" pipe branches and the
and the wall or other structural
building element.
•
Adequate pipeline and waste wa-
ter collection
drains) should be ensured on the
location of the installation or ad-
equate electric system, in case of
auxiliary electric heating.
•
In order to keep heat loss at min-
imum, it is highly recommended
that you install the buffer tank as
close to heat consuming units as
possible. It is also reasonable to
provide insulation for the water
pipes.
•
Unused connection pipe branches
of the buffer tank should be
location protected
systems (floor
closed and it is proposed to pro-
vide heat insulation for them.
•
Mount a drain tap on the drain-
age pipe branch of the tank.
IT IS AT THE RISK OF DEATH AND
THEREFORE IT IS FORBIDDEN TO
PUT THE WATER TANK AND THE
HEAT EXCHANGERS
PRESSURE LARGER THAN THE PER-
MITTED OPERATION PRESSURE.
THESE VALUES ARE DESCRIBED IN
TABLE 1.
It is obligatory to build in the
security valve, but this lies out-
side the scope of shipment of
the appliance.
IT IS FORBIDDEN TO MOUNT WA-
TER PIPELINE FITTINGS BETWEEN
THE SECURITY VALVE AND THE
BUFFER TANK.
Before mounting the valve, water
pipelines have to be flushed thor-
oughly, in order to avoid any dam-
age caused by any possible pollu-
tion.
PUTTING INTO OPERATION
Deploying the unit and putting it
into operation can only be per-
formed by a professional techni-
cian. After mounting, the pipelines
and the tank have to be flushed
thoroughly, then the tank has to be
filled up with water. Check the op-
eration of the security valve and
have the possibly accumulated air
blown down. Before its first use,
the buffer tank has to be fully filled
up with water and cleaned from air.
