Water to be Treated

The IAB Commercial Series 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 Commercial Series System 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 connection at the back of the unit

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.

Operation

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

The IAB Commercial 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 backwash filter; then it enters the turbojet that distributes it uniformly, at high speed, on the entire inner surface of the cartridge.

The IAB Commercial System is equipped with two voltage-free contacts, which are activated according to an advanced preset by the program that determaines 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.

Electrical Checks After Installation

After connecting the filter to the power supply, the display will automatically turn on; the filter reaches the filtration stage and the display switches off.

After this stage, check the operation of the circuit by manually pressing the up and down arrow buttons simultaneously, until the motor starts; the filter performs a backwashing procedure.

Check the correct functioning of the backwash solenoid valve. The solenoid valve is in closed position during the backwashing operations performed by the filter and in open position during filter operation.

Hydraulic Checks After Installation

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

1. Verify that the equipment is correctly positioned in order to ease ordinary maintenance.
2. Check for the presence of a by-pass circuit allowing to exclude the filter from serving and check for the presence of sampling faucets installed upstream and downstream the filter.
3. Check for the compliances of the installation with all local rules or recommendations issued by the competent local area offices.
4. Verify that there are no leaks from the inlet and outlet connections and from the filter drain connection.

In case of doubt please contact the Puretec Customer Service Helpline on 1300 140 140 (Australia) 0800 130 140 (New Zealand).

Flow Direction

WARNING: It is critical the system is installed following the water flow direction as indicated by the arrows on the brass head of the filter. Any other arrangement may cause damage or cause the system to function incorrectly. The filter discharge connection must be conveyed away from the unit in a drain line.

Electronic Circuit Backwash

• The IAB Commercial Filters back-washing is automatically activated every 12-24 -36-48 hours.

The circuit shows three connecting cables located in the back of the filter;

• The first cable comes pre-connected directly to the pressure differential;
• The second cable, in central position, is the power cable which has to be connected to the power supply dedicated plug provided;
• The third cable is a voltage free contact, for the management of auxiliary devices serving the filter (solenoid valves, pumps, alarm etc.); being a voltage free contact electrical loads must not be applied on it.

2. Unscrew the three fasteners that fix the white cover with the help of a screwdriver, as shown in Fig. A below.

3. Carefully remove the white cover plate. Facing the gear-motor of the filter, on the right side of the filter locate the D.I.P. switch (Fig. C, details circled in red).

4. The D.I.P. switch is a small block made of 4 white switches with ON-OFF position. (see Fig. E).

5. In order to move the lever, use a small screwdriver, make them go up and down.

6. The switches D.I.P. 1 and D.I.P. 2 are used to set the backwashing duration.

7. The switches D.I.P. 3 and D.I.P. 4 are used to set the waiting time before starting the back-washing cycle.

8. After adjusting the D.I.P. switch place the white cover back in position paying attention to the power cable position and screw the three fasteners to secure, ensuring not to overtighten.

9. Insert the plug. The filter will carry out the probationary test washing. When it is finished the device is ready to use with the new washing program set

Back Washing Interval Programming and Waiting Time Before Backwashing Programming.

The IAB is equipped with an electronic D.I.P. switch circuit (Dual In-Line Package Switches) which by changing the position of four switches allows to program:

• D.I.P. 1 and D.I.P. 2 switches: interval duration setting between two backwashing 12-24-36-48 hours.
• D.I.P. 3 and D.I.P. 4 switches: waiting time before the effective start of the backwashing 0-30-60-100 seconds setting. This interval is useful to give any motorized solenoid valve time to respond.

Indicator Lights

Motorized Drain Valve

The IAB Commercial filter is equipped with automatic drain valve directly managed by electronic panel of the filter.

This allows the filter to work in particularly heavy operations, for example the presence of high levels of sediment (ex. sand) that could lead to a malfunction of the drain system.

Maintenance

Before carrying out any maintenance/work on the filter other than the automatic backwashing operation, disconnect the filter from the power supply and place the filter in the by-pass position.

Cleaning

The cleaning of plastic parts can only be performed with a soft damp cloth, without using any solvents, soaps or acid detergents.

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 IAB Commercial System should also be included in the maintenance plan.

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.
