Before Installation
Before Installation
Before installing the lter, make sure that the system complies with any
local laws or regulations.
The IMB System is not equipped, in its standard version, with anti-ooding devices or
with devices aimed at verifying, checking and triggering an alarming in the event of
uncontrolled water leaks. If necessary, purchase and install a suitable anti-ooding device
separately.
Ensure there is an appropriately size drain available for the back washing
Do not install the IMB System downstream of boilers or in applications involving the
passage inside the lter of water above 30 °C. Install the IMB lter upstream of the
equipment to be protected.
Pay attention to the threads of the connections that could cause hand cuts and
abrasions.
Installation Note: A water lter system/tap, like any product, has a limited life and may
eventually fail. Also sometimes failure happens early due to unforeseen circumstances.
To avoid possible property damage, this product should be regularly examined for
leakage and/or deterioration and replaced when necessary. A drain pan, plumbed to an
appropriate drain or outtted with a leak detector, should be used in those applications
where any leakage could cause property damage, and/or the water supply should be
turned o if no one is home/present.
Positioning the IMB System
The IMB System must be installed in a hygienically suitable, dry, clean place, indoors,
away from: frost, direct exposure to sunlight, humidity and atmospheric agents (rain,
snow, hail).
Do not install the IMB System in wells, near drains or in foul-smelling places.
Do not install it where there may be chemical vapors, gases or fumes of any kind. Avoid
installation in conned spaces that restrict performance or maintenance operations.
The permissible limiting values of the environmental parameters for the installation of
the IMB System are: Min/Max Ambient Temperature 0 - 40 °C (protect from freezing).
Assembly
The lter is supplied with the water inlet on the le.

Installation
Installation
Installation must be carried out by a qualied tradesperson, in compliance with all local
laws.
The plumbing system in which the lter is installed and the installation of the lter itself
must be carried out in compliance with local laws.
Puretec is not responsible for damages to property or persons resulting from the
incorrect installation of the lter and/or the installation of the lter in a system not
complying with the local laws.
All materials used for the construction of water distribution systems for human
consumption must comply with local laws. The construction and modication of a water
distribution system intended for human consumption requires modications to be carried
out in such a way as not to jeopardise the hygiene of the system.
Aer its construction or modication, a water distribution system intended for human
consumption has to be washed and disinfected according to the requirements of local
law.
The lter must not be installed between the boiler and the safety devices.
A non-return valve should be installed in conjunction with this product, along with a by-
pass valve for untreated water.
Ensure there is an appropriate point for drainage.
Prevent solvents, oils, greases, acidic or caustic substances and detergents from coming
into contact with the external plastic and brass parts of the equipment.
In case of damage during transport or assembly, do not install the equipment.
If the system is subject to water hammering, install an appropriate damping system. If
the water pressure can exceed the maximum operating pressure of the lter even for
short periods, install a pressure limiting device.
Avoid overhead installation in order to prevent damages to property or
persons in the event ofa fall, a collapse or water leakages.

Installation
• Remove the top and bottom green rings to remove the plastic covers.
• Install the lter, ensure that the water is ow direction matches the ow direction
arrow as indicated by the arrow stamped on the brass lter head. Make sure there
is enough room around the lter so the cover can be removed for easy access.
• Install the piping in the and inlet and outlet sides of the lter head.
• Replace the plastic covers and rings.
Note: The lter MUST be installed following the water ow direction indicated on the
lter head. On installations with the inlet water on the right, the label with technical data
would stay behind the lter (facing the wall). Any other arrangement may cause incor-
rect operation of the device. The lter discharge must be canalised in a view drain.

Performance Data
Water to be Treated
The IMB System is not designed to lter closed circuit water, water containing large
quantities of sand or coarse particles larger than 2 mm, silt or chemicals (oils, solvents,
acids, bases, glycols).
Operation
Oen lters exclusively remove the dirt accumulated in the bowl, without cleaning the
cartridge. The Puretec IMB Series guarantees an ecient and thorough cleaning of the
lter cartridge too, thanks to its brushing and drainage functionality.

Maintenance
Maintenance
Filter Cleaning
Puretec recommends backwashing the screen every 3-4 days, or at user dicretion,
whenever there is a drop in presure. If necessary, backwashing can be repeated.
During the backwashing process, the lter discharges some water . This discharge can be
run o to a drainage point.
The cleaning of plastic parts can only be performed with a so damp cloth, without using
any solvents, soaps or acid detergents.
Note: In order to obtain eective cleaning of the lter, a minimum water pressure of
2 bars is required. If necessary, during the lter cleaning operation , the shut o valve
positioned downstream of the lter should be closed.
Periods of Non-Use
For periods of non-use less than 30 days, perform the lter cleaning operation repeatedly
(4-5 times). For non-use periods longer than 30 days, perform lter sanitisation.
Non-use means the that the plumbing system remains still without any water being
drawn from the taps (e.g. holiday period).
If the plumbing system is subject to cleaning and sanitising maintenance, the IMB system
should also be included in the maintenance plan.
Note: The sanitising maintenance and must be carried out exclusively by a qualied
plumber.
