1. Installation of the Doulton HCP under-counter system

1.1 Water Pressure Information

The HCP housing unit has satisfied the NSF Std 53 structural test criteria. However, due to the potential wide variations of pressures from one installation to another the manufacturer advises that if there is any doubt that the system would see pressures above 100 psig (approx. 6.9bar) then an approved pressure reducing valve bought from a good hardware store and set at 100psig (approx. 6.9 bar) should be installed upstream of the filter to eliminate any extreme variations in pressure. Water fittings for use in permanently pressurized systems may have a finite life. It is important that the plastic components in the system are replaced after 10 years of usage.

1.2 Selecting a position for the Water Filter System

The filter should be fixed to a unit or wall with the screws and bracket provided near the incoming cold water supply, and the desired position for the faucet. N.B. This filter is not designed for the treatment of hot water and should only be connected to the cold water supply. Make sure that the filter is located so that the length of tube provided does not have any sharp bends in it. For easy servicing of the filer there should be at least 4 inches of clearance below the body of the filter to allow for removal of the cartridge for cleaning or renewal. Choose a position for the connection into the water supply, which allows for cutting the pipe and flexing the ends into the push-fit T. Check that the supply pipe is 3/8" od copper- if in doubt ask your plumber.

1.3 Connecting Pipework and Fittings

The filter is supplied with 3/8" push-fit connections for ease of assembly.

1.4 Assembling and Fixing the Filter

(i) Having chosen the position for the water filter (see 1.2 above), mark the position of the bracket fixing screws (10) on your wall/unit.

(ii) Attach the bracket (12) to the filter cap (3) by using the 3 self-tapping screws (11) provided.

(iii) Attach the bracket and lid to the wall/unit with the bracket fixing screws.

(iv) Isolate the water supply at the stop valve and cut the copper pipe at the required position. It may be necessary to cut out a length of the copper pipe.

(v) Deburr the edges of the copper pipe with a file and push the ends of the pipe (4) into the push-fit "T" and the other into the inlet connection of the filter cap (3) ensuring that the arrow on the cap is showing the correct direction of water flow.

(vii) Drill a hole 1/2" diameter in the countertop in the desired location for the faucet (6).

(viii) Slide the escutcheon plate and black rubber washer on to the threaded stem of the faucet. Locate the threaded stem of the faucet through the drilled hole, slide on the black locating washer, the lock washer and lick into position with the back nut provided.

(ix) Screw the push-fit adapter (5) onto the threaded end of the faucet under the counter top.

(x) Push one end of the flexible tube (4) into the outlet of the cap and the other end into the push-fit adapter.

(xi) Place the cartridge washer (9) onto the threaded nipple on the cartridge(8) and screw the thread into the cap until washer resistance is felt. N.B. Do not overtighten. When the cartridge seal is made, moisten the O-ring on teh filter body and replace it onto the location groove. The body can now be screwed to the cap. If there is less than 10" clearance below the base of the filter housing, place the filter body in position over the cartridge before screwing the cartridge into the cap. Hand-tighten only.

2. Conditioning the Filter

The System should now be ready for pressurization. With the user tap/faucet in the on position, gradually open the upstream isolation valve until the flow from the tap has stabilized at the recommended flow rate. Then close the user tap/faucet and ensure that there is no water leaking from the system joints. When the system has been confirmed watertight, open the user tap and allow the water to run to waste for a minimum of 10 minutes. When water first comes out, it is normal for some grey dust to be flushed from the filter. Allow the filter to stand for 24 hours to condition the filter to the source water and then flush for a further 10 minutes to waste.

After carrying out this procedure, the filter is now ready for use. During use, contaminants filtered from the water may build up on the outer surface of the ceramic cartridge and cause a reduction of flow through the unit. The cartridge will, therefore need cleaning to restore the flow. Cleaning frequency will be dependent upon the condition of the incoming water.

3. Servicing the Filter

Cleaning, removal and reinstallation/replacement of the cartridge is carried out as follows:

With the upstream isolation valve off, vent the pressure by opening the user tap. Place a bowl under the filter body. Unscrew the filter body, which will be full of water, and lower the body into the bowl. The cartridge can now be unscrewed from the cap and cleaned in accordance with the manufacturer's instructions or replaced as described in section 1.4 . When the cartridge has been re-installed, wipe the filter housing clean with a damp cloth.

Cleaning/Sterilizing the Filter Housing:

If it is necessary to clean or sterilize the housing, the following substances should be avoided:

(a) Strong oxidizing agents such as bleach or Milton solution

(b) All strongly acidic materials including some descalents.

(c) Strongly alkaline materials.

If a new cartridge is installed, condition this cartridge for use in accordance with the cartridge manufacturer's instructions. It is important to wash your hands thoroughly after servicing the filter.

Note: Where high particulate (dirty) water leads to regular blockage of the ceramic cartridge, it may be necessary to install an approved 5 micron cartridge pre-filter system, bought from a good hardware store. A cartridge that has reached the end of it's life would be indicated by a reduction in the quality of the filtered water with respect to taste. The cartridge should be replaced in accordance with the rated service capacity, which would typically give a period of six months usage.
