Operating and Maintenance Instructions - Storage Water Heaters
1.1 Preparing for installation
1.1.1 Transport, handling and
unpacking
The storage water heater may only
be transported in depressurised
condition. Suitable stops should be
used to ensure that no deformation
or other damage to the outer
surfaces or sealing surfaces occurs
during transport. The storage
tank must not be allowed to strike
supports, flanges, etc. The tank
may only be set down and rested
upon suitable supports (wooden
frame, palettes), which are supplied
with the heater. Point loading of the
tank wall can lead to impermissible
deformations. Transport and storage
at temperatures below the frost
limit (0°C) are not permitted (frost
hazard due to any residual water
in the tank). All openings, such as
filler necks, flanges, etc., should be
sealed using suitable means, which
may only be removed by competent
personnel (caution: do not damage
sealing surfaces!) When removing
the components from the packaging
it is necessary to proceed with great
care. If storage tanks are removed
from a container, care should be
taken that the breathers that protrude
from the top of the tank are not
damaged or bent when passing the
opening.
1.1.2 Non-return valves for cold
water supply and circulation
connections
Non-return valves must be provided
for the secondary domestic cold water
supply and circulation connections, in
order to avoid possible convectional or
expansive back ow of heated water.
1.1.3 Filter recommendations
To avoid damage to pumps and fouling
of heat exchangers by intake of foreign
bodies, ECOTHERM recommends that
strainers be placed in front of supply
connections as follows:
Primary circuit heating water supply:
Strainer mesh size 150 - 200 µm.
Secondary circuit cold water supply:
Strainer mesh size 50 - 60 µm
1.1.4 Primary circuit heating water
pressure from boiler
The heating water supply to the heat
exchanger has minimum pressure
requirement of 1.5 bar, and a maxi-
mum of 10 bar. Failure to observe this
requirement may potentially expose
the primary circuit to negative pressure
aeration. ECOTHERM recommends
that a closed expansion vessel with
pressurised ll-up be tted to the pri-
mary circuit.
1.1.5 Secondary circuit expansion
vessel
An expansion vessel connected to
the domestic hot water supply line is
required to allow for the increase of
water volume during heating. Failure
to observe this requirement may result
in regular small losses of heated do-
mestic water through the ECOTHERM
product‘s own pressure safety valve
during heating.
1.1.6 Tank legs
Tank legs MUST NOT under any
circumstances be screwed or xed to
the oor, otherwise expansion strain
will cause cracks, which may lead to
leakage. The tank must be placed on
the oor, supported by its legs, which
must be able to move slightly as
the tank expands or contracts. (The
screw holes in the base of the legs
are for transportation purposes only.)
1.1.7 Copper piping and water
bourne chloride ions
The following applies to installations
with copper piping and water borne
chloride ions (> 100 mg/litre):
1.1.7a Isolating connectors
All connections must be electrically
isolated from the copper piping using
the special isolating ange kits and
isolating screw connectors provided.
1.1.7b Non-sacricial electric anode
Where supplied the non-sacricial elec-
tric anode must be connected to the
mains power supply and be operational
at all times, in order to inhibit galvanic
transport of material away from stain-
less steel surfaces.
1.1.7c Simple repair of stainless steel
tanks
Please note that in the unlikely event
of pitting occurring, affected stainless
steel areas can be quickly and cheaply
repaired to 100% serviceability on site
by your local ECOTHERM Support
Centre using specialised techniques
developed by ECOTHERM. Stainless
steel therefore offers the best possible
choice for better hygiene, durability and
longer life.

Operating and Maintenance Instructions - Storage Water Heaters
2.3 Safety guidelines
Installation and connection should
only be carried out by approved
contractors in accordance with
applicable regulations and technical
specications.
Approved safety devices shall be
installed In the cold water supply.
The operating pressure stated on the
rating plate must not be exceeded.
With higher line pressure, a pressure
reducer should be tted, whose
function can be controlled by a
downstream test valve.
The safety valve shall be tted in the
cold water pipe and there should be
no mean of isolating this valve from
the vessel. Fitting of dirt traps or other
restrictions in the supply line is not
permitted. The safety valve shall be
installed to react at the permissible
operating pressure at the latest.
The cross section of safety valve
piping (max. 2 elbows, max. length 2
m) shall be at least that of the safety
valve. The outlet of the safety valve
should ow into an tundish to enable
observation, and the drainage piping
should be arranged to ensure that any
blow-off of steam or hot water cannot
cause danger to persons present.
The drainage piping after the tundish
must be of at least twice the cross
section of the valve inlet. Safety valve
and and drainage pipes shall be
designed frost-proof and may not be
routed to atmosphere. In the vicinity
of the safety valve a warning sign
shall be provided bearing the following
inscription:
Electrical connection must only
be carried by qualied specialist
personnel of an accredited electrical
contractor. For electrical connection,
the ÖVE and TAEV regulations with
the appropriate design specications
shall be complied with.
For cleaning and service of the system
the electric power supply must be
disconnected.
Prior to initial start-up the entire water
heater must be carefully ushed and
checked for proper installation. Initial
start-up may only be performed by an
ECOTHERM service engineer.
For safety reasons, it is normal
for small quantities of water to
escape from the safety valve
during initial heating. Do not
block the safety valve.

Operating and Maintenance Instructions - Storage Water Heaters
Commissioning, lling, venting and servicing the system
3. Commissioning
3.1 Commissioning
Commissioning may only take place
when the heater has been properly
installed in a system and the approp-
riate limitation devices provided and
set up, the set-up conditions have
been fullled and the installation has
been checked for proper tting, set-
up conditions and safe operation.
When starting up, the heater should
be continuously observed and
checked for any leaks. In normal
operation the storage tank may only
be operated if equipment required for
safety reasons is continuously effec-
tive and is not disabled or its function
according to the specications modi-
ed during operation. The heater was
designed for static operation.
3.2 Flushing the system
Prior to initial commissioning the enti-
re system should be carefully ushed.
Foreign bodies in the system impair
the working order or safety of the de-
vice. Approved safety devices should
be tted in the cold water supply pipe.
4. Cleaning and servicing
4.1 Cleaning and servicing of tank
vessel
ECOTHERM storage water heater
will increase its life and reliability.
Depending on water condition, regu-
lar checks of the inner tank vessel
are recommended. (min. 1x/year)
4.1.1 Important checks!
Control the tightness of the ange
and the storagetank periodical.
ECOTHERM cannot accept any liabi-
lity for damage caused by water. After
every maintenance of the ange, a
new seal must be installed.
Before starting-up the pressure ves-
sels it is absolutly necessary to re-tig-
hten the bolts! Bolt torque setting Nm
see at rating plate.
Do not cross thread the bolts.Prior to
tting, check screws for damage to
threads.
4.2 Closing and opening the storage tank
Storage tanks must be sealed such that all seals provided are used in
accordance with specications. Sealing surfaces must be clean and unda-
maged. Screwed sealing plugs may only be carefully and uniformly tightened
as far as necessary for sealing. The quoted tightening torques should be
adhered to. The screws may not be released on pressurised storage tanks.
Seals and inspection openings on the storage tank may not be opened until
the pressure has been equalised with the atmosphere. The pressure equali-
sation with the atmosphere should take place after the closing of the pressu-
rised supply pipe by loosening or aerating, whilst observing the pressure gau-
ge. After this, the screwed sealing plugs are loosened such that they can still
retain the sealing cover. Then this should be opened slightly and loosened
until it no longer adheres to its seat.
