SECTION III: PREPARATION 

 

 
A. Major System Components 

 

 

The following components comprise the R.O. Drink-
ing Water System: 

 

1. A Reverse Osmosis assembly consisting of the 

aluminum bracket, filter housings, automatic 
shut-off, membrane module and an in-line 
carbon filter.  

  
2. A drinking water holding tank.  
 
3. A faucet kit. 
 
4. A plastic tubing kit with self-piercing saddle valve 

and drain clamp. 

 
5. 

Other items necessary for installation may 

include wood screws or machine screws for 
mounting the R.O. assembly concrete anchors 
may be required for hanging on basement wall, 
additional tubing or tube connectors, and plastic 
wire ties for organizing tubing. 

 
Note:   For systems equipped with Quick Connect 
fittings, see page 11.  
 

B. Tools Recommended for Installation 

 

The following tools will cover most of the installation 
sites encountered: 

  3/8" variable speed electric drill.  

  Extension work light with outlet.  

  Safety Glasses.  

  1-1/4" porcelain hole cutter kit.  

  1-1/4" Greenlee hole punch and 1/8" and 

1/2"metal drill bits for pilot hole.  

  Center punch and hammer.  

  1-1/4" wood bit.  

  Assorted wood and metal drill bits including 

7/32" metal drill bit.  

  Phillips head and flat blade screwdrivers.  

  1/2", 9/16" and 5/8" open end wrench.  

  10" Crescent wrench with jaws taped to 

hold faucet.  

  Teflon tape.  

  Wide masking tape or duct tape.  

  Plastic tubing cutter.  

  Extra plastic tubing.  

  Low range air pressure gauge.  

  Bicycle hand air pump.  

  Small bottle of liquid chlorine bleach.  

 
C. Determine System Location  

 

The R.O. system can be located under a sink or in 
a basement depending on space availability and 
the custom

er’s preference.  If a basement 

installation is selected, additional tubing, hardware 
and fittings may be needed and a hole will have to 
be made from inside the cabinet, through the floor, 
to the basement. Never install in an area of the 
home where temperature is freezing as damage to 
the system will result.  
 
Considerations for an ice maker or other remote 
hook up should be determined, including routing 
and any additional tools, fittings, and tubing that 
may be required.
