1. GENERAL INSTRUCTIONS FOR SAFE WORK
• The contents of the INSTRUCTIONS for installation and assembly must be followed carefully, otherwise warranty claims cannot be
asserted. The tank must be inspected prior to installation and veried whether it has been manufactured in accordance with your
requirements. The instructions, which are attached to the bottom of the lid, must be removed, together with the bag and clips.
• Installation shall be carried out by a professional company with qualied experts, who are familiar with the installation instructions.
• Follow the instructions for safe work when executing the works; another person must be present to protect you, especially when
manipulating and installing the tank.
• The lid of the tank must be kept closed at all times to prevent the possibility of an accident.
• The tank shall be installed only into previously prepared construction pits and backlled according to the manufacturer’s
instructions.
• Placing the tank out in the open is forbidden.
• The choice of lid type depends on the order and the buyer’s wishes.
• Only those additional elements that have been specied and authorised by the manufacturer of the tank can be tted onto the
tank. In the event of the installation of unsuitable elements, the manufacturer cannot guarantee proper operation; hence, the
buyer cannot assert the warranty rights.
• The images contained in the instructions for installation and maintenance are merely illustrative.

3. INSTALLATION OF TANK
3.1. PREPARATION OF TANK
All the basic versions of tanks include a custom-made water outlet. Using a suitable double connector or reducing connector you can
connect the outlets to the desired spot. Before lowering it into the construction pit, the tank must be inspected to make sure it was
not damaged during transport and whether it appears awless on the outside.
3.1.1. Assembly of Fittings
The tank’s entry ttings dier and are adapted to your requirements. You must choose a suitable pipe and the appropriate entry seal.
The installation of the seal and the execution of a suitable opening must be carried out by a qualied individual with the tools suitable
for such a task (a hole saw, a scraper, a food-grade lubricant etc.)
3.2. EXCAVATION OF A CONSTRUCTION PIT
NOTE: maximum depth of tank entrenchment amounts to h + 500mm. The construction pit must be excavated at a min. angle of 15º.
H = hof tank + sand bedding
L = Type of tank + 1m
Ø = Type of tank + 1m

3.3. MAKING AND PREPARING THE BEDDING
The body of the tank must be placed on top of suitable bedding. The latter must be solid and compact. Appropriate backll material must
be used. When using granular material, the permissible grain size is from 0 to 32mm or from 0 to 16mm when using crushed material.
Do not use frozen material. Suitable bedding thickness is from 20 to 30cm and must be compressed to 97% Proctor compaction. When
groundwater is present, the bedding must be made out of MB15 lean concrete.
Sand bedding min. 20cm

3.4. BACKFILLING AND PLACEMENT OF TANK
Backlling the body of the tank requires the use of appropriate backll material (the same as was used for making the bedding) and
the proper execution of backlling.
The backll material has to be consolidated and compressed carefully and in layers (up to 30 cm in height) to 97% Proctor compaction
over a minimum width of 50cm from the wall of the tank. Simultaneously with backlling the body of the tank, water must be poured
into the tank itself, so that the level of the backll material equals the water level in the container. When backlling, pay special
attention to the space on the bottom. Using manual aids, ll in and consolidate the entire empty space, thus preventing potential
subsequent deformation of the bottom.
When backlling the PE container, make sure that heavy construction machinery does not drive over the body or in the area of
backlling.
Filling with water in stages - min. 30cm
Backlling and consolidating
in layers min. 30cm

3.5. ASSEMBLY OF THE TANK IN THE EVENT OF GROUNDWATER
In the event that groundwater is present throughout the entire height of the tank, the body of the tank must be encased in 30cm thick
concrete, up to the height of the maximum groundwater level or minimally to the height of 70cm. Wire mesh and an additional wire
rod are inserted into the foundation slab in order to attach a galvanised fastening steel tape. The fastening tape is xed in place with
three M8x40 stainless screws. The fastening tape may enclose the body of the tank and must not be subjected to a tensile force that
would deform the shape of the body of the tank.

The tank has a factory-installed walkable PE lid with seal, which can be replaced with a cast-iron lid at the request of the buyer. Prior
to any assembly of the lid, the seal of the lid must be cleaned and lubricated with a food-grade lubricant. In the case of a lid with a
seal, a safeguard can be ordered as an extra, which protects the lid from being opened. This is especially important when children or
under-age persons are in the vicinity of the tank. The decision of choosing a lid with a safeguard is made by the buyer; hence in the
event of an accident, the seller and manufacturer shall not be held liable for potential consequences if a lid without a safeguard has
been chosen.
4. ASSEMBLY OF THE LID AND FINISHING WORKS
After the backlling of the tank is nished, the height of the manhole has to be adjusted to the surrounding terrain by cutting the ring
of the tank. Factory-made tags, which allow horizontal cutting, have been made for this purpose. The tank can be made higher, but
the total height of the reservoir must not exceed h + 500mm.
