Preface
ETAbox Operation
Preface
Dear Customer,
The satisfactory function of your new ETAbox
depends to a large extent on its installation. So
before starting the installation, please invest
around 15 minutes to get an overview with this
manual.
Note boiler manufacturer's specifications
The conditions specified in the boiler
manufacturer's technical documentation must
be adhered to (e.g. maximum distance between
ETAbox and boiler, maximum height difference,
pellet store specifications, electrical connections,
settings...)
Contact a component's manufacturer to ascertain
its usability.
Warranty and guarantee
You should also read the "Warranty, guarantee and
liability conditions" on page 4 of this manual
carefully. All of the requirements we impose are
intended to prevent damage that neither you nor
we wish to occur.
Training the customer
To avoid errors in operation, please explain to your
customer (preferably using this manual) exactly
how the ETAbox works and how it should be
operated and maintained.
Rules for safe operation
Discuss the rules for safe operation of the system
with your customer, preferably before beginning to
use it as afterwards it could already be too late.
Extended warranty for commissioning performed
by an authorised partner company
If we supplied the boiler and ETAbox and the
newly installed heating system was commissi-
oned by an authorised partner company or by our
customer service, we offer an extended warranty
on all system components supplied by us. Refer
to our warranty conditions in effect at the time of
purchase.
Service agreement
You can ensure the best care for the ETAbox by
taking out a service agreement with one of our
certified heating system contractors or our own
customer service.

Warranty, guarantee and liability conditions
Warranty, guarantee and liability conditions
Subject to technical alterations
To give you the benefit of our ongoing develop-
ment efforts, we reserve the right to make tech-
nical changes without prior notice. Printing and
typesetting errors or changes of any kind made in
the interim are not cause for claims.
Scope of delivery
Individual configurations depicted or described
here are only optionally available. In the event
of contradictions between individual documents
regarding delivery scope, the information in our
current price list applies.
Warranty, guarantee and liability
We can only guarantee and accept liability for the
function of the ETAbox if it is properly installed and
operated.
Precondition for warranty, guarantee and liabi-
lity is that the following general conditions be
observed during installation and operation:
The ETAbox is intended for filling with wood pellets
(ÖNORM M7135, DIN 51731, DINplus, EN 14961-2
and ENplus A1) with a diameter of 6 to 8 mm
and a length of 15 to 40 mm. If the ETAbox or
parts thereof are used for any other purpose, no
guarantee or functionality claims may be asserted.
The fabric sack must be protected from sharp
objects, UV light and water.
Repairs are only permitted with spare parts
provided by us. The only exceptions are common
standardised parts such as fastening materials, as
long as they possess the required features and do
not restrict the functionality of the system.
The installing contractor is liable for proper
installation according to the boiler's installation
instructions and the relevant rules and safety
regulations. If you as customer have installed the
heating system partly or entirely without relevant
training and in particular without up-to-date
practical experience, without having the installa-
tion checked by a trained and responsible expert,
we exclude defects in our delivery and consequen-
tial damages resulting from this cause from our
warranty, guarantee and liability.
The ETAbox guarantee only applies as far
as the pellet hose connections to the boiler. No
comprehensive guarantee claims may be asserted.

For safe operation
Ventilation
The store must be ventilated through windows,
doors or air inlets and outlets as carbon monoxide
can form where pellets are stored.
Container wall across from couplings must be 200
mm from wall
to cushion the impact of the pellet stream during
injection and avoid damage to the pellets while
filling.
ETAbox may not be in contact with damp walls
Rooms with the dampness of a normal cellar do
not pose a problem, but the ETAbox may not come
into contact with damp walls.
No sharp or pointed objects
No sharp or pointed objects that could damage the
fabric are permitted in the vicinity of the ETAbox.
No UV light
Do not allow the ETAbox to be exposed to UV light
under any circumstances. No fluorescent lamps
in the room. Cover cellar windows with dark
foil or use UV protective film if they must remain
transparent.
Outdoor set-up possible with rain shelter
In the event of outdoor set-up, the ETAbox must be
protected against weathering (rain, wind, exposure
to sunlight and UV light). A watertight roof and
side walls are an absolute requirement. The pellet
hoses must also be protected against UV light and
sunlight.
Official permits and fire safety
Official permits (building authorities, trade autho-
rities) may be needed for operation.
Local building and fire safety regulations must be
observed. Consult your local authorities.
Switch off heating system during maintenance
Switch off the main switch on the boiler before
any work on the ETAbox and the pellet conveyor
system. If the ETAbox has a power supply separate
from that of the boiler, switch that power supply
off as well. If there is no switch, isolate the ETAbox
from the mains using the trip switch (RCD).
Switch off 3 hours before filling?
If no ETA boiler is being used, switch off the
heating system at least 3 hours before filling the
ETAbox to avoid back-burning.
If the ETAbox is being used with an ETA pellet
boiler, the heating system may remain switched
on. An ETA boiler is equipped with a draught fan
and ventilated rotary valve to protect against
back-burning.
Use back air hose while filling
The ETAbox must be filled at underpressure. While
pellets are being blown in, air must be simultane-
ously removed through a second hose, ensuring
nearly dust-free fill-up.
Open door or window while filling
To minimize the amount of dust escaping from
the container during filling, more air should be
extracted than is blown in. To ensure the necessary
air supply for the room, open windows and/or
doors while filling.
Do not operate conveyor screw without vacuum
motor
Without removal of pellets, the conveyor screw
will jam. If the boiler's vacuum motor fails, the
conveyor screw will draw more current and the
fuel conveying system will be switched off before
the screw can jam.
Setting for current monitoring
To protect against jamming, current monitoring
must be correctly set on the boiler, for the ETAbox
2.1 A nominal current and 3.0 A maximum
current.
Prevent unauthorized access
Lock the room where the ETAbox is installed in
order to keep out children and pets.
