HOW TO INSTALL YOUR TS LINE HEATER
WARNING: All wiring and installation must be
supervised by a suitably qualified person.
WARNING: Do not install this unit where it may be
subjected to freezing conditions.
This electric water heater complies with the requirements
of EN 60335-1, EN 60335-2-21.
I. PURPOSE OF USE
The appliance is designed to supply hot water to
household facilities equipped with a piping system
operating with pressure not greater than 5.5 bars.
It is designed to operate only in closed and heated
premises where the air temperature is not lower than
4°C and it is not designed to operate in a continuous
protracted regime.
II. TECHNICAL SPECIFICATIONS
1. Nominal volume 10 or 15 litres - see the appliance‘s
rating plate
2. Nominal voltage - see the appliance‘s rating plate
3. Nominal power consumption - see the appliance‘s
rating plate
4. Nominal pressure - see the appliance‘s rating plate
ATTENTION! This is not the water mains pressure. This is
the pressure that is rated for the appliance and refers to
the requirements of the safety standards.
5. Water heater type - closed accumulating water heater,
with thermal insulation
6. Inner coating: Glass-ceramic
7. Daily energy consumption – see Annex I
8. Rated load profile - see Annex I
9. Quantity of mixed water at 40°C 10 & 15 litres - see
Annex I
10. Maximum temperature of the thermostat - see Annex I
11. Default temperature settings - see Annex I
12. Energy efficiency during water heating - see Annex I
III. IMPORTANT RULES
Do not switch on the water heater until you are sure
•
that it is filled with water.
A suitably qualified person must perform the
•
connecting of the water heater to the water supply.
A suitably qualified electrician must perform the
•
connecting of the water heater to the electric network
(for models without a fitted plug).
Connecting the water heater to the electric mains via
•
a plug must only use the plug supplied
If the water-heater will not be used for longer than
•
3 days and the temperature in the premises could
drop below 4°C, the water in the water heater must
be drained to avoid any possible damage of the
appliance. (please observe the procedure outlined in
subsection 2)
During operation, the appliance may produce a
•
“hissing” noise (the boiling water). This is normal and
does not indicate any damage or a fault. This noise
may increase in volume over time as limescale is
deposited. To remove the noise, the appliance must
be de-scaled thoroughly. Failure to de-scale the
appliance regularly in hard water areas may impair its
performance and affect the warranty.
For safe operation, the safety return-valve must undergo
•
regular cleaning and inspection for normal functioning,
the valve must not be obstructed, and for the regions
with hard water it must be de-scaled as necessary. This
service is not provided under warranty maintenance.
All alterations and modifications to the water
•
heater‘s construction and electrical circuitry are
undertaken entirely at the purchaser’s risk and
are NOT recommended. Any such alterations or
modifications may invalidate the appliance‘s
warranty.
Alterations and modifications shall include any
•
instances of removal of elements incorporated by the
manufacturer, building in additional components,
replacement of elements by those not approved by
the manufacturer.
If the power cord (of models that have one) is damaged,
•
it must be replaced immediately by an appropriately
qualified person, in order to avoid any risks
IV. DESCRIPTION OF THE APPLIANCE
The appliance consists of a body, flange, plastic control
panel & safety return valve.
1. The body consists of a steel reservoir (water tank) and
plastic housing (outer shell) with thermal insulation
placed in-between, and two threaded pipes for the
cold water supply IN (marked with a blue ring) and
hot water discharge OUT (marked with a red ring). The
inner reservoir is steel protected against corrosion by
a special glass-ceramic coating.
2. The flange is fitted with the electric element and a
magnesium anode. The flange is fixed to the water
tank with bolts.
Instructions for use and maintenance 3
The element heats the water in the tank and is controlled
by the thermostat, automatically maintaining the preset
temperature. The plastic control panel incorporates: switch
(depending on model), adjustable thermostat (depending
on model), and thermal cut-out and control lamps.
The thermal cut-out switches off the power supply should
the water temperature reach excessive values. If this device
is actuated, you should call a the service helpline above.
The signal lights on the control panel indicate the current
mode of the unit.
The magnesium anode provides additional anticorrosion
protection to the internal tank.
3. The safety valve prevents the appliance from
emptying in the event of cold water supply
interruption. The valve protects the appliance from
pressure increases higher than the allowed value
during heating (note: pressure will increase when
temperature increases), by releasing the excess
pressure through the drain outlet. Excess water exiting
into the drain during the heating process is a normal
event that must be taken into consideration when the
boiler is installed.
ATTENTION! The safety valve cannot protect the
appliance in the event of water mains pressure exceeding
the rated pressure stated for the appliance (6 Bar).
V. INSTALLATION AND SWITCH ON
1. Installation
We recommend installation of the device close to the
likely outlet (i.e. Tap) where hot water is used, in order to
reduce heat losses. The selected installation location must
be clean and dry at all times.
The appliance is affixed to a wall by means of mounting
brackets attached to the unit‘s body.
Two hooks are used to fix the appliance (min. Ø 6 mm)
firmly on the wall (included in the mounting set). The
bearing plank construction for boilers installed under
sinks is universal and allows the space between hooks
to vary between 96 and 114mm. (fig.2)
IMPORTANT: The TS Line Boilers are designed for
installation under sinks with the outlet/inlet pipes
pointed upwards (to the ceiling). Under no circumstances
should these units be fitted upside down, with the outlet/
inlet pipes pointing towards the floor.
For clear understanding of wall installation schemes,
please refer to fig.2.
ATTENTION! Don‘t place objects, which are not
waterproof under the appliance under any circumstances.
2. Water heater connection to the water supply system
Cold Water Pack Instructions
When water is heated
it expands. In a small
unvented water heater of
this type the expansion
can normally be
accommodated back into
the cold water mains, as
indicated in the Water
Regulations.
Where this is not possible
the installer will need to fit
a set of cold water controls
