VI. Filter Life

Filter life will vary in proportion to the amount of water used and the level of impurities in the water being processed. Claims of capacity are not applicable to contaminants reduced by mechanical filtration because of broad variations in the quality and quantity of physical matter in your drinking water. Your Multi-Pure filter will clog, protecting you from these contaminants, and your flow rate diminishes. For contaminants reduced by adsorption, filter life/capacity is 750 gallons.

It is recommended that filters be replaced annually or sooner if needed. For optimum performance and to maintain your warranty, it is essential that the filter be replaced on a regularly scheduled basis as follows: (a) annually; (b) when the unit's rated capacity (750 gallons) is reached; (c) the flow rate diminishes; (d) the filter becomes saturated with bad tastes and odors.

VII. Instructions for Changing Your Filter

REMOVING THE OLD FILTER

1.Remove the shipping materials - plastic wrapper and instruction wrapper.

2.It may be advisable to place a folded towel beneath the housing before opening it. Or you may place it in your sink or in a pan to open.

3.Confirm that your tap water is off.

4. Open the diverter valve by pushing the bypass lever (Fig. A) so that the

Fig. A

water flows through the unit and the filtered water spout until the flow

 

stops.

 

5.When the flow of water stops, then close the diverter by pushing the bypass valve.

6.With the housing in an upright position, or on its side on a towel, use the Water Guardian hand tool to open the unit (Fig. B).

a.Slide the hand tool over the housing top so that the ridges on the tool fit into the grooves on the housing top.

b.Hold the base in place on the countertop and apply steady pressure to

the hand tool to turn the top.

c.Once the top is loose, you can complete the opening process by turn- ing it with your hand.

7.Remove the housing top from the base (Fig C).

8.Remove the old filter (cartridge) from the unit base by pulling out and slight- ly twisting the filter until it is released from the base as shown in Fig. D. Make sure black gasket remains on bottom of housing base.

9.Wrap the used filter in paper and dispose of it in your normal refuse.

10.Clean and rinse out the inside of the housing.

INSTALLING THE NEW FILTER

bypass lever

11.Insert the new filter in the center port of the housing base, twisting slightly, as shown in Fig. D. Then push straight down on the filter to assure that is firmly in place.

12.Reconnect the housing top with base (Fig. C).

13.Hand-tighten the housing top by turning it clockwise. The top should be securely connected to the base so the o-ring at the bottom of the top is not visible. If necessary, use the hand tool, shipped with your unit, to tighten the top (Fig. B-1).

a.With the housing in an upright position, slide the hand tool over the top so that the ridges on the tool fit into the grooves on the housing top.

b.Applying steady pressure, turn clockwise to tighten. Hold the base in place on the countertop while turning the top.

c.Tighten sufficiently so that the o-ring on the top threads is not visible.

DO NOT OVER TIGHTEN.
