Before Installation

Before installing the filter, make sure that the system complies with any local laws or regulations.

• The IMB+ 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 appropriate-sized drain available for the back washing
• Do not install the IMB+ System downstream of boilers or in applications involving the passage inside the filter of water above 30 °C. Install the IMB+ 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 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 outfitted 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 off 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 confined spaces that restrict performance or maintenance operations.

Assembly

The filter is supplied with the water inlet on the left.

Installation

• Installation must be carried out by a qualified tradesperson, in compliance with all local laws.
• The plumbing system in which the filter is installed and the installation of the filter 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 filter and/or the installation of the filter 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 modification of a water distribution system intended for human consumption requires modifications to be carried out in such a way as not to jeopardise the hygiene of the system.
• After its construction or modification, a water distribution system intended for human consumption has to be washed and disinfected according to the requirements of local law.
• The filter 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 filter even for short periods, install a pressure limiting device.

Avoid overhead installation in order to prevent damages to property or persons in the event of a fall, a collapse or water leakages.

• Remove the top and bottom green rings to remove the plastic covers.
• Install the filter, ensure that the water is flow direction matches the flow direction arrow as indicated by the arrow stamped on the brass filter head. Make sure there is enough room around the filter so the cover can be removed for easy access.
• Install the piping in the and inlet and outlet sides of the filter head.
• Replace the plastic covers and rings.

Note: The filter MUST be installed following the water flow direction indicated on the filter head. On installations with the inlet water on the right, the label with technical data would stay behind the filter (facing the wall). Any other arrangement may cause incor-rect operation of the device. The filter discharge must be canalised in a view drain.

Hydraulic Checks After Installation
After having opened the water upstream of the equipment, check for any leaks.

1. Check that the appliance is correctly positioned so as to ease ordinary maintenance operations.
2. Check that the system is equipped with: disconnector, by-pass, sampling taps
3. Verify that there are no leaks from the inlet and outlet fittings and from the filter drain.

Model Specifications

*Micron rating is nominal. ˜If pressure exceeds max pressure, an approved pressure limiting device needs to be fitted. Note: Check local plumbing regulations as a specific kPa limit for the pressure limiting valve may be required (in particular, The Australian & New Zealand Plumbing Standards. Ref. AS/NZS 3500.1:2021, Clause 3.3.4). If water hammer is present, fit a hammer arrestor close to the source of the hammer.

Water to be Treated
The IMB+ 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).

Operation

Often filters exclusively remove the dirt accumulated in the bowl, without cleaning the cartridge. The Puretec IMB+ Series guarantees an efficient and thorough cleaning of the filter cartridge too, thanks to its brushing and drainage functionality.

Maintenance

Filter Cleaning
Puretec recommends backwashing the screen every 3-4 days, or at user discretion, whenever there is a drop in pressure. If necessary, backwashing can be repeated.
During the backwashing process, the filter discharges some water . This discharge can be run off to a drainage point.
The cleaning of plastic parts can only be performed with a soft damp cloth, without using any solvents, soaps or acid detergents.

Note: In order to obtain effective cleaning of the filter, a minimum water pressure of 2 bars is required. If necessary, during the filter cleaning operation , the shut off valve positioned downstream of the filter should be closed.

Periods of Non-Use

• For periods of non-use less than 30 days, perform the filter cleaning operation repeatedly (4-5 times). For non-use periods longer than 30 days, perform filter 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 qualified plumber.

Periodic Checks
It is advisable to have a check performed every six months by an qualified plumber in order to ensure the system continues to perform.

Preventative Maintenance
Preventative maintenance or repair, if not correctly performed, can compromise the functional and/or safety features: these operations are deliberately omitted in this user guide.
Therefore, all preventative maintenance and repair not mentioned in this user guide must be carried out exclusively by Puretec or their agents.
