PIPE INSTALLATION
GENERAL
Pipe installation must be carried out in accordance with
current norms and directives.
The accumulator tank/water heater must be fitted with
the necessary valves, such as a safety valve, shut-off
valve and non-return valve.
The accumulator tank/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.
NOTE
Beware of any water splashes.
There is a risk of scalding.
Ensure that incoming water is clean. When using a
private well, it may be necessary to supplement with
an extra water filter.
If uncertain, contact a plumber alternatively see applic-
able standards.
INSTALLATION
The accumulator tank/water heater is installed upright
or horizontally. During upright installation, the accumu-
lator tank/water heater is levelled using four adjustable
feet. During horizontal installation, the accumulator
tank's/water heater's mounting rail is used.
A separate base is available as an accessory for horizont-
al installation.
SP 300 can be supplied for upright installation, with an
electric heater ELK-213 if threaded flanges are first in-
stalled on the connections (XL35), threaded flanges are
available as an accessory.
For horizontal installation, a circulation pump must be
installed.
NOTE
Electrical installation and service must be car-
ried out under the supervision of a qualified
electrician, and in accordance with applicable
electrical safety regulations.
