1.3 Overview Filter Components HN-G models are automatic, self-cleaning screen-type water filters. The filtration system consists of a filter body, hydraulic piston, filter screen, Self-Clean mechanism and drain valve.

2. Installation 2.4.1 Location: IMPORTANT The HN-G filter should be installed vertically Allow a minimum clearance of 10” (ten inches) above the HN-G for safe removal of the filter cover. Locate the HN-G filter as close to a drain as possible. This will maximize the efficiency of the automatic self-cleaning. An AC to 12VDC power source is required for the Backwash Controller if batteries are not used (HN-G-01-1-XXX, HN-G-02-1-XXX models only). - Page 5 2.4.2 Installation requirements When installing the ¼” plastic tubing into the appropriate fittings – push the tubing in hard, it should go in about a ¼”. It should be tight into the fitting and does not come out when you pull on it. The drain pipe should be a minimum of 1.25”...

5. Maintenance This filter, while automatic in function, is not maintenance free. It is expected that the screen will require pressure washing on a periodic schedule to remove contaminants that have stapled into the screen. Depending on the contaminant, the frequency can vary from once a week to twice a year. - Page 9 21. Carefully replace the Hydraulic Motor and Plate into the Filter Housing , ensuring that the Piston Shaft is inserted into the hole in the middle of the Inlet Disc 22. Push down firmly on the Plate . When correctly in place the central collar of the Plate will be flush with the top of the Housing .
- Page 10 area and solenoid. It is usually easier to just unscrew the top of the valve cover and drain the diaphragm area that way. Manually cleaning the Filter Screen element before storage is also a good idea. That will prevent debris from drying on the screen and becoming difficult to remove the following season.

- Page 12 Notice that before the first use of the unit, it may be necessary to pass through the configuration process prior to defining the flushing program in order to adjust the features of controller to the specific application. The configuration process is described below. 6.2.1 The chain of editable fields Below is the chain of editable fields.
- Page 13 6.2.4 The Flush Mode The Flush Mode defines how the flushing cycles is triggered. The selectable options are as follows: OFF - No flushing will take place By time – In this case the flushing cycles will be repeated in a selected interval or will be triggered by the DP signal depending on what happens first.

Looping limit the number of consecutive flushing cycles triggered by the DP sensor before deciding that there is an endless looping problem. The options are: 1-10 or “no” which means ignoring the looping problem. Alarm Yes/No – allocating one output for alarm activation. Delay Valve Yes/No –... - Page 15 A. Appendix A.1 DC MODEL The drawing below shows the wiring of the DC model of the controller. Notice that: The External DP sensor is optional and it is intended for use in cases there is no Embedded Electronic DP included.

C. Installation Example 1 How your filter is installed will depend on how your system is structured and the specific requirements of your site. This example illustrates a stand-alone filter installation with minimal added components in discharge plumbing like what is located on a municipal feed water source (or pumped water where the pump is located remotely). - Page 19 D. Installation Example 2 This example illustrates a filter installation in discharge plumbing located on the output of a pump and also a controlled outlet valve on the discharge of the filter to accommodate low flow rate applications where all pressure and flow must be utilized for backwash (the controlled outlet valve can also be applied in installation example A and C).
