Position
Installation can only be performed by an authorised plumbing installer, and in accordance
with the Danish Building Code. Tank and pipes cannot be exposed to freezing. Position the
heater close to its water supply and a floor drain. Ensure that there is sufficient room for
service and maintenance.
Electrical water heaters must always be mounted vertically and with the spouts downwards.
Distance to the floor for wall-mounted models shall be min. 400 mm and distance to ceiling
should be min. 200 mm (figure 1). If suspending a water heater, always use the ceiling-
mounting bracket supplied.
Check that the wall can bear the weight of the tank when full of water.
A stand and plate set with adjustable feet is available for models 60, 110 and 160, making it
possible to install a water heater on a level, firm surface.

Risk of corrosion
METRO THERM hot water tanks are made of enamelled steel, and protected by a magnesium
anode. If connections and pipes are copper or stainless steel, there can be risk of galvanic
corrosion at the point of connection. The risk can be mitigated by using a PEX pipe adapter
between tank and pipe installation.
The water heater is fitted with PEX bushings for cold and hot water supply pipes. These bush-
ings protect the enamel coating and must not be removed.
The water heater must be installed as a pressurised tank with shut-off, non-return and safety
valves, e.g. METRO safety device. The safety device must be positioned as shown in figure 2.
Using softened water in a METRO THERM tank
Water softened using salt can be used in a METRO THERM hot water tank. However, we
recommend removing the anode before the tank is used, to avoid degradation of the anode.
If the anode is degraded, the water can begin to smell, glasses in dishwashers can be stained
a milky-white and sulphur hydroxide can form, which cause the tank to begin to sputter.
Do not use demineralised water (double ion exchange), which will rapidly corrode the tank.
Demineralised water is also referred to as totally desalinated or deionised water.

Safety device
The safety valve must be mounted on the cold water supply pipe close to the tank, and easily ac-
cessible for service and testing. It must be impossible to shut-off the pipe connecting safety valve
and tank and the overflow from the safety valve. Diameter min. 3/4” (20 mm.). The overflow outlet
must be visible and run to a drain. It must not run outdoors to protect it from freezing.
The safety valve must be able release the rated output of the water heater at least. The use
of a METRO safety device (figure 3) fulfils this requirement. Because water expands when
heated (approx. 2%), the safety valve must drip during heating.
Installing circulation
A plastic plug is fitted in the top plate. Under the plug (in the insulation) is a connector
(3/4”internal RG) with plug (NV 26).
Forced circulation
We recommend forced circulation with a pump mounted using a circulation kit (supplied as
accessory). The circulation kit consists of an enamelled extension pipe to be fitted in the top
of the water heater, and a PEX pipe fitted at the bottom (figure 4).
Natural circulation
If connecting the water heater to natural circulation, the hot water outlet must be connected
to the top of the tank. The circulation circuit should be connected to the hot water outlet in
the base, and the PEX pipe in the hot water outlet shortened to a length of 2/3”.
NB:
The customer must be made aware of heat loss from the circulation circuit, and the extra run-
ning costs that will incur. Circulation can be controlled by a timer.
High circulation loss can cause breakdowns if the control system is set for ECO operation. In such
instances, it may be necessary to switch the control system over to manual operation, when the
tank temperature can be controlled in the same way as a standard electrical water heater.

Electrical installation
Electrical installation can only be performed by an authorised
electricalinstaller.
The water heater has splashproof IP24 encapsulation and must always be extra-protected in
accordance with the LVD directive.
The water heater is fitted with Smart Control, which includes a thermostat, a thermal fuse
and a display for setting the different forms of control systems and temperature levels.
Smart Control
The water heater is fitted with a thermal fuse to prevent overheating, and that can be recon-
nected. The fuse can only be reconnected by an authorised electrician. The fuse is located under
the plastic plug in the baseplate, by the yellow sticker.
The Smart Control system with thermostat and thermal fuse is located under the water heater
baseplate. The Smart Control display is located on the bottom of the front, and is used to set
various forms of control systems and temperature levels.
Remember that the sensor tube from the thermostat and thermal fuse must extend as far
from the spade terminal on the heating element as possible.
Electrical heating element – up to 3 kW
3 kW/400 V – 1 kW/230 V
The standard heating element can be connected to 400 V (3 kW) or 230 V (1 kW), see wiring
diagram.The water heater is supplied from the factory with a 4-wire cable (with no plug) to be
connected to mains electricity. If the cable is damaged, it must be replaced (can be purchased as
a spare part).
Remember! The water
heater must be filled with
water before connecting
electricity.

User Guide
Read this manual carefully before installation and using the water heater.
Safety regulations
Installation, first activation and maintenance of this product can only be performed by an
authorised plumber/electrician, who will be responsible for observance of the relevant standards
and installation regulations. We cannot be held liable for damage or injury caused by failing to
observe the safety regulations.
Risk of flooding and freezing
If the water heater is mounted in a holiday home, or a house which is uninhabited for long
periods, we recommend draining the entire water installation to damage caused by freezing. If
there is no risk of freezing, shutting-off the water supply at the mains cock will be sufficient.
Smart Control
Smart Control consistently reads actual patterns for household hot water consumption, and only
heats up the amount of water needed at any given time. That saves energy, and ensures that
there is always sufficient hot water.

Start
When switching on electricity for the water heater – at the mains switch – the Smart Control
will run a short test, during which the seven diodes will light in turn. After a few seconds, ECO
mode will automatically cut in, using comfort level 2, meaning that the water heater is working.
The diode opposite the comfort level in use will flash when the heating element is on.
Control system modes
The Smart Control has three different control system modes: ECO, Manual and Holiday. Select the
function required by pressing the mode selector button until the diode for the mode required lights.
• ECO
Economy mode, in which Smart Control consistently reads actual patterns for household hot
water consumption, and only heats up the amount of water needed at any given time.
The consumption pattern established in week 1 is used to forecast the amount of hot water
needed at the right time in week 2. If the pattern changes, the Smart Control will automati-
cally adapt accordingly in the following week.
Four comfort levels can be selected, from 1 to 4, by pressing the level selector buttons +
(arrow up), and – (arrow down), until the diode by the comfort level required comes on.
The lowest comfort level is no. 1, which uses the least energy, but also sticks closest to last
week’s actual hot water consumption pattern.The higher the comfort level, the higher the
amount of extra hot water is needed compared to the forecast. There is therefore greater
likelihood that there is always sufficient hot water – but also higher energy consumption.
Comfort level no. 2 is factory default setting, which is also used for energy rating testing for
the electrical water heater.

13
• Manual
Smart Control works as a traditional electrical hot water heater thermostat, heating up the
entire tank to the temperature selected.The temperature can be selected at four comfort
levels, from 1 to 4, by pressing the level selector buttons + (arrow up), and – (arrow down),
until the diode by the temperature level required comes on.
Temperature level no. 1 = 60°C and should normally be used, as it minimises limescale ac-
cumulation on the heating element, extending its service life.
Temperature level no. 2 = 65°C should only be used if level no. 1 does not provide sufficient
hot water. The higher temperature will mean accelerated limescale accumulation on the heat-
ing element.
Temperature level no. 3 = 70°C and no. 4 = 75°C can only be used if an anti-scolding device
is also installed on the hot water outlet of the tank. Otherwise, there can be a danger of
scolding! Limescale accumulation will also be significantly higher.
• Holiday
“Standby” mode, in which the Smart Control turns down the temperature in the tank to
prevent freezing, to 6°C. No higher temperature level can be selected in this mode.
Legionella protection
The Smart Control always runs with a Legionella protection function, which constantly monitors
the water heater's function.Any breakdown which could allow the Legionella bacteria to exist
will result in the temperature in the tank being automatically raised to 65°C and maintained
until any bacteria have been eradicated.
Child lock
The Smart Control can be set in a mode in which its functions are locked, to prevent changes
being made to the settings. The child lock is activated by simultaneously pressing the mode but-
ton and level button – (arrow down), until the diodes light in turn for ECO + Manual and level
3+ 4. The child lock can be deactivated using the same process as activation.

14
Fault indicator
The Smart Control can detect and provide a warning for the following faults. The water heater
will automatically stop working in the event of a fault!
• RESET
Once the cause of a fault has been eliminated, the Smart Control must be RESET before it
starts working again. To do so, press the level selector button + (arrow up) and – (arrow
down) simultaneously.
• No water in the water heater
If there is not enough water in the tank when the heating element comes on, the Smart
Control will provide a warning by alternately flashing the diodes level 1 + 3 and level 2 + 4.
The diode for the selected mode will be off.
• Abnormally long heating time
If it takes an abnormal amount of time to heat the water, the Smart Control will provide a
warning by alternately flashing the diodes level 1 + 3 and level 2.The diode for the selected
mode will be off. This will usually be due to the thermal fuse cutting out, or a faulty heating
element.
• Other faults
If any other faults occur – such as a defective temperature sensor, water temperature
over 90°C, or a fault in the control system – the Smart Control will provide a warning by
alternately flashing the ECO + Holiday and Manual diodes, and the diodes for levels 1 to 4
will all be off.
NB:
Pipes and fittings near the water heater can reach temperatures over 60˚C.
The water heater is fitted with a thermal fuse that will cut-out in the event of overheating.
The fuse can only be reconnected by an authorised electrician.
Disposal
Ensure disposal of the product in the most eco-friendly manner. Private owners must comply
with local municipal rules for disposal of domestic waste.

15
Maintenance
External cleaning
The tank can only be cleaned with a damp cloth. Window or glass cleaner can be used, but
not scouring cream/powder or solvents. Always read the instructions on the cleaning product.
Safety valve
Always inspect the safety valve at least twice annually. The plumbing installer can show you how.
When testing, water should flow out of the valve.
Limescale removal guide
Limescale removal can only be performed by an authorised installer.
Always replace the gasket. Never re-use the old gasket.
• Disconnect electricity supply at the mains, and shut off water supply at the shut-off valve.
• Drain the tank.
• Remove bottom cover to access the heating element. This is a ceramic heating element
placed in an immersion pipe in the bottom flange (flange pipe).
• Disconnect wires on the heating element, carefully extract the capillary pipes
from the small immersion cover.
• Remove the flange. The gasket may need to be cut free from the tank. Use a thin-bladed
knife. The flange pipe can be difficult to get through the opening if heavily scaled with lime or
other deposits. Ease it carefully out, as aggressive handling of the enamelled parts can cause
damage, which can later lead to corrosion.
• Remove loose limescale. Loosen limescale caked on the element by tapping gently,
e.g. with a piece of wood.
• Rinse out remaining limescale from tank.
• Replace the flange with a new gasket and spacer ring on the outside of the bolts (figure 8).
Tighten the bolts in diagonal cross-sequence to 15 to 17 Nm.
• Fill with water and check for leaks by pressure-testing at water pressure of 10 bar.
• Replace the capillary pipes and wires Ensure the Smart Control sensor is positioned well
inside the immersion cover.
IMPORTANT! Check that the capillary pipes fit before touching conductive parts.

Checking/replacing the anode
Must be performed by an authorised plumbing/electrical installer. The tank is fitted with
a magnesium anode that can be inspected. It is fitted in the bottom flange, and can be
inspected by removing the connection to the tank and inserting a multimeter (see figure 9).
If the anode current reading is greater than 0.3 mA, the mass of the anode is sufficient to
protect the tank. If the reading is less than 0.3 mA, the anode should be replaced. To do so,
drain the tank and remove the flange pipe (figure 10).
