Before Installation
Before Installation
Before installing the filter, make sure that the system complies with any local laws or regulations.
The IAB System is not equipped, in its standard version, with anti-flooding 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-flooding device separately. Ensure there is an appropriately size drain available for the back washing Do not install the IAB System downstream of boilers or in applications involving the passage inside the filter of water above 30 °C. Install the IAB filter 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 filter system/tap, like any product, has a limited lifespan and if not replaced, will eventually fail. Failure can happen 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. We strongly recommend that a drain pan, plumbed to an appropriate drain or outfitted with a leak detector, be used in those applications where any leakage could cause property damage. We also strongly recommend that the water supply be turned off, upstream to the water filter system/tap, if no one is home for an extended period of time.
INSTALLATION SHOULD BE COMPLETED BY QUALIFIED TRADESPEOPLE. FAULTY OPERATION DUE TO UNQUALIFIED PERSONS WILL RESULT IN VOIDED WARRANTY COVERAGE.
Positioning the IAB System
The IAB 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 IAB 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 confined spaces that restrict performance or maintenance operations. The permissible limiting values of the environmental parameters for the installation of the IAB System are: Min/Max Ambient Temperature 0 – 40 °C (protect from freezing).

Installation

Water to be Treated
The IAB System is not designed to filter closed circuit water, water containing large quantities of sand or coarse particles larger than 2 mm, silt or chemicals (oils, solvents, acids, bases, glycols).

Precautions
The IAB is a piece of equipment connected to 220 Volt power supply. The plug has to be inserted into a standard socket, provided with a ground contact and protected by a residual current circuit breaker. Check that the plug is firmly inserted into the socket and located in a protected area, away from accidental contact, water splashes, humidity and heat sources. Before maintenance, disconnect the filter from the power supply.

Power Supply Connection
Insert the power connection plug into the hole on the right when looking at the back of the unit (as shown in Fig. 1).
When the filter is switched on, it will automatically re-position itself.
In the event of a power failure, the filter retains the last programmed setting when it is switched on again.

Fig. 1

Operation
Often filters exclusively remove the dirt accumulated in the bowl, without cleaning the cartridge. The Puretec IAB Series guarantees an efficient and thorough cleaning of the filter cartridge too, thanks to its brushing and drainage functionality.
The IAB System is equipped with an electronically controlled automatic cleaning system with timer. This solution ensures optimal cleaning of the filter cartridge every time.
During the filtration stage the water enters the diverter, goes down through the filtering cartridge, from outside to the inside, and then comes out filtered.
During the backwashing stage, the incoming water is diverted and passes through a

Performance Data
backwash filter; then it enters the turbojet that distributes it uniformly, at high speed, on the entire inner surface of the cartridge. The IAB System is equipped with two voltage-free contacts, which are activated according to an advanced preset by the program that determines the start of the backwash cycle. In the event of a power failure, the filter retains the last programmed setting when it is switched on again. The consumption of water when cleaning is approximately 14 litres.
