INTRODUCTION: 

Now that you have bought your 

Berkey

 water purifier, you have taken the first step towards protecting you and 

your family from disease causing viruses, pathogens and other waterborne contaminants that may be in your 
water. 

 

The ease of operation of this unit combined with a proven effectiveness at eliminating waterborne diseases and 
contaminants has led to 

Berkey

®

 water purification elements being specified for field operations by many of the 

world’s major aid and emergency relief organizations.

ASSEMBLY INSTRUCTIONS: 

1. 

Assemble your 

Berkey

®

 system as cleanly as possible. Extreme cleanliness is 

important. Wash your hands and 

Berkey

®

 system before proceeding to assure 

that contamination of the components does not take place during assembly. 

Note: 

You can run a few batches of water through your 

Berkey

®

 system and then use 

the filtered water to clean your hands and your system. 

2. 

Remove the purification elements and parts from their protective packaging, 
checking each item against the above list. Prime

 

Black Berkey™

 

purification 

elements 

(see reverse side of this instruction sheet or 

Black Berkey™

 element 

instruction sheet). 

3. 

Place the large sealing washer (9) over the threaded stem of the element (8) 

(Washer rests on inside bottom of upper chamber (2)). 

4.  Place element stem into the hole in the base of the upper chamber (2). 
5.  Secure element in the chamber base by screwing the wing nut (10) onto the 

threaded mount.  Repeat #3 & #4 until all elements have been installed.  

Note: 

Tighten moderately, do not over-tighten wing nut.

 

6. 

For BL systems having more element holes than purification elements (expandable 
systems) secure rubber blocking plugs into empty holes.

  

7. 

Place the exterior beveled washer (4) over the threads of spigot (7) with the bevel 
facing the system. Insert threaded stem of spigot through hole in the side of the 
lower chamber (5) insert internal flat washer over threads and secure it in place with 
the spigot nut (3).  Tighten securely by hand only.  

Hint: hold nut in place and gently 

turn spigot until tight then rotate spigot until handle is facing upward. 

8. 

Turn lower chamber upside down on a counter or other flat surface and place base 
(11) onto bottom of lower chamber with large opening facing downward. 

Align 

seams on lower chamber and base, slip nipples on left side of lower chamber 
under lip of base opening and apply downward pressure onto right side of 
base with a slight twisting motion until base snaps onto lower chamber. Note: 
Some units may not snap. 

 

 

9.  Turn upper chamber upside down on a counter or other flat surface with opening 

facing downward.  Place connected lower chamber and base onto bottom of upper 
chamber, opening facing downward. 

Align seams on lower and upper chambers, 

slip nipples on left side of upper chamber under lip of lower chamber opening 
and apply downward pressure onto right side of upper chamber with a slight 
twisting motion until upper chamber snaps onto lower chamber. Note: Some 
units may not snap.

 

10.  Turn entire assembled system upright. You are now ready to begin operating your 

Berkey Light

®

 water purifier. 

(Note: With systems containing LED lamps, rotate 

base until switch is on opposite side of spigot).

 

11. 

See back page for operational and maintenance instructions.

 

NOTE: ALIGN SEAMS WHEN 

ATTACHING BASE AND CHAMBERS, 
SLIP LEFT NIPPLES UNDER LIP AND 

APPLY PRESSURE TO RIGHT SIDE. 

Optional LED Base Operation:

 Plug in AC 

adapter and 

charge batteries for 24 hours 

before using LED lamp base.

 Nickel cadmium 

(Ni-Cad) batteries have a memory therefore it is 
important to fully charge them before use and it 
is beneficial to fully discharge them before they 
are again recharged. If electricity is available, the 
AC adapter or the internal rechargeable batteries 
can power the LED base. When power is not 
available, the 

Berkey Battery Adapter™

 case 

(optional) provides an incredible two weeks of 
nighttime light from four small AA alkaline 
batteries and the 

Berkey MP Solar Charger™

  

(optional) provides for an endless source of 
power. Note: AC adapter for 120V power only. 
Step down adapter required for 220V power.

 

WARNING: Failure to read, thoroughly understand, and follow all instructions may result in personal injury, 
water damage, or voiding of the warranty! It is the assembler’s responsibility to make sure all components are 
properly assembled and installed using the instructions provided. While your 

Berkey

®

 system should not 

have any leaking problems, there is always the chance that a leak might occur due to being improperly 
assembled or perhaps a faulty part. In an overabundance of caution, we recommend that for the first 24 hours 

the filled system be placed in an area wherein if such a leak were to occur, the resulting spillage would not 
damage anything within the household.
