9. Installing the Cartridges

 

The cartridges are identified by the color of the label and 
the model number.

 

Cartridge #1 = PW-S2500R, Yellow 

Cartridge #2 = PW-C5000R, Blue 

Cartridge #3 = PW-RO75R, Green 

Cartridge #4 = PW-C2500R, Violet

 

Install the cartridges in order. If the cartridges are installed 
out of order the system will not filter correctly.

 

A.  Slide the cartridge into the head until it stops.

 

B.  Twist the cartridge 1/4 turn clockwise until it snaps into 

place. Gently pull out on the cartridge to ensure the 
cartridge is locked into place.

 

11. Putting the System Into Operation

 

CAUTION 

Make certain head assembly is firmly attached 

to wall to prevent it from falling and possibly 
becoming damaged.

 

NOTE: Use caution not to bend or pinch the tubing behind 

the system while attaching to mounting screws.

 

NOTE: The post-polishing filter may contain fine black 

carbon particles. These fines are harmless, but 
may make the water appear gray in color. The 
carbon fines are flushed from the system with the 
first tank full of water.

 

NOTE: The PB4RO system does not produce a high 

volume of water on demand as an ordinary filter 
does. Water is produced at a slow, drop-by-drop 
rate. The system requires about 3 hours to fill the 
storage tank. As water is taken from the tank, the 
system automatically starts the cycle of replacing 
the water and then stops water production when 
the tank is full.

A.  Make sure cold water faucet is “off” (Figure 14).

 

B.  Make sure tank valve is in the open position.

 

C.  Slowly turn on cold water supply.

 

D.  Open the faucet to turn on flow. Let the faucet run/drip 

for 12 hours, then close it.

 

E.  Allow 3 hours for the tank to fill. Continue to periodically 

A

 

check the installation for leaks. After the storage tank

 

is filled, open the faucet to flush the post-filter cartridge 
(on the right side of the filter housing). Allow 4 to 5 
minutes for all of the water to drain from the tank. Close 
faucet and allow tank to fill.

 

CAUTION 

Visually check the entire system for leaks. If a leak is

 

10. Connecting the Storage Tank to the System

 

CAUTION  

When  tank  is  full,  it  weighs  approximately  35 

pounds.   Provide   ample   support   under   the   tank.

 

A.  Apply 3-5 wraps of Teflon tape to the tank threads.

 

B.  Thread the tank valve onto the top of the tank opening 

by turning it clockwise until snug.

 

C.  Locate the green tubing and a mark 3/4" from the end.

 

Moisten one end of the green tubing with water and 
insert with a twisting motion into the free port of the tank 
valve until the 3/4" mark is flush with the quick-connect 
fitting.

 

NOTE: Do not cut green tube. This line should be left at 

the pre-cut length for future service.

 

NOTE: The pressurized storage tank has capacity of

 

3.2 gallons. The tank's air pressure is factory 
set at 5 to 7 psi when tank is empty.

 

present, see TROUBLESHOOTING.

 

F.   Repeat Step E four times.

 

NOTE: Initially, the water may appear cloudy. This is a 

result of air trapped in the post-filter cartridge. 
It is not harmful and will disappear in a matter 
of minutes. It may take up to a week after 
installing a new post-filter cartridge for the 
trapped air to dissipate.

 

The system is ready for operation. You can now enjoy quality 
water from the PB4RO-75.
