Assembly Instructions

Mount the hot water wall storage unit as described in the diagram.
Observe the instructions in the text. You will find the diagrams at
the beginning of the manual.
4.2 Assembly
Assembly Preparation
Closed Operation
Mount close to the tap from which the most hot water will be extracted.
A design proofed safety valve combination is to be installed. In addition,
if water pressure exceeds 0.48 Mpa (4.8 bar), a pressure reducing valve
is to be installed and adjusted accordingly. No shut-off valves may be
installed between the safety modules and the reservoir. Discharge from
the safety valve must always be open. The safety valve combination for
closed operation must be accredited (design proofed):
Safety valve combination AK030300, i.e. safety valve combinations
with pressure reducing valve AK040300 can be mounted with a
customary thermostat pre-mixer.
Note: According to the Energy Conservation Act, the
temperature in the mains system must be limited to 60°C
for hot water pipes longer than 5m.
Open Operation
An appropriate overflow mix regulator is to be installed:
BZ12411 wall temperature regulator with bath spout, shower hose and
hand sprinkler; or BZ11114 wall regulator with shower hose and hand
sprinkler. The discharge from the fitting must always be free. Never use
an aerator! A back-flow preventer is to be installed in the cold water
intake.
Wall Assembly (page 22, diagrams 6 to 8)
The assembly diagram is on the packaging. To allow for replacement of
the heating flange and anti-corrosion anode, at least 500mm of free
space must be left underneath the reservoir. Use appropriate screws
with a diameter of at least 12mm. Provide a special supporting structure
for lightweight walls.
Mount TR5500T 120... and TR5500T 150... with both mounting
brackets. Vertically align TR5500T 80... and TR5500T 100...with the
wall separator C.
Water Connection (page 23/ 24, diagrams 9 to 11)
Only detachable connections are permissible!
Before connecting the fittings, thoroughly flush out the water pipes in
order to remove any impurities.
For closed operations, if the safety valve is not directly above the drain,
then the drain pipe must be mounted at a continuous downward slope in
a frost-free environment.
Please take care because of application range within water types
according to technical data on page 16.
4.3 Operating Modes
Single Power Operation
Connection without off-peak contact.
The appliance heats with the adjusted performance.
The "fast-heating" button is only used for the reset and diagnose
functions.
Connection with off-peak contact
If the "fast-heating" button is activated, the device heats once to the
configured temperature. All 6 LED thermal capacity indicators
light up as soon as the configured temperature has been
14
reached. Afterwards, the device turns itself off automatically.
Double Power Operation
Connection without off-peak contact.
The reservoir heats with the configured basic performance.
The reservoir heats with the configured basic performance.
The "fast-heating function" activates a heating cycle at higher installed
power in order to accelerate the heating-up procedure. To start this
function, press the fast-heat button
lights up. The function turns itself off automatically, as the soon as the
configured temperature has been reached. The LED "fast-heating" turns
off .
Connection with off-peak contact
During off-peak time the device heats with the configured basic
performance. The "fast-heating function" activates a heating cycle at
higher power in order to accelerate the heating-up procedure. To start
this function, press the fast-heat button
lights up. The function turns itself off again automatically as soon
as the configured temperature has been reached. The LED fast-heating
turns off.
The rest of the time, the device does not heat. If the "fast-heating" button
is activated, the device heats once to the configured temperature.
All 6 LED thermal capacity indicators light up as soon as the configured
temperature has been reached. Afterwards, the device turns itself off
automatically.
Boiler Mode
Connection without off-peak contact.
The device does not heat by default.
If the "fast-heating" button is activated, the device heats once to the
configured temperature. All 6 LED thermal capacity indicators
light up as soon as the configured temperature has been
reached. Afterwards, the device turns itself off automatically.
Each further heating process must be started by pushing the button
"fast-heating" .
Electrical Connections
WARNING:
▶ Danger of electric shock! The power switch "S1"
may only be activated in an unpowered state!!
Remove lower cap by taking the screws out (page 24, diagram 12).
Lead cable through the cable gland and cord grip and connect, then
tighten the cable gland and cord grip (page 25, diagram 13).
Check that the system is suitable for the maximum power absorbed by
the water heater (please refer to the data plate) and that the cross-
section of the electrical connection cables is suitable, and no less than
2
2.5 mm .
Operating mode
Set the power switch "S1" to the correct operating mode on the
electronic board.
Set the desired load according to the connection examples.
