INSTALLATION PROCEDURE

1. Turn off  water supply and depressurize lines before installing fi lter.
2. Install fi lter using Rainfresh Connector Kits CK1P for Inline (Fig. 1) or CK3 Kit 

for undersink (Fig. 2) or standard pipe fi ttings in desired location making sure 
water enters inlet side of fi lter as marked on Filter Head.

3.  Remove sump by turning 1/8th turn counterclockwise and lower. Remove 

protective bubblepack around 1M Cartridge. The fi lter unit comes with a 
ceramic adaptor (1007-0) that is threaded onto the cartridge and allows a 
simple press up fi t of the cartridge over the center boss of the fi lter head (501).  
To replace sump, align the sump grooves with fi lter head (501) lugs and push 
straight up onto the head. Turn the sump 1/8 turn to right to lock. 

Please keep the cartridge adaptor for use with future 
replacement cartridges.
NOTE: THE CERAMIC CARTRIDGE IS FRAGILE AND SHOULD BE HANDLED WITH 
CARE.

4. Open valves before and after the fi lter. 
5. Turn on water supply and check for leaks. 

Flushing and Conditioning: 

Allow water to fl ow for 10 minutes to fl ush unit, 

then close faucet and allow unit to sit overnight to condition. In the morning 
fl ush unit briefl y before beginning service.

NOTE:

 In some cases with low water pressure, the sump may only partially fi ll 

due to an air block. If this happens, turn off  faucet and press top vent button until 
water level rises past the sealing point on sump.

YOUR UNIT IS NOW IN OPERATION.

WHEN & HOW TO CLEAN THE CARTRIDGE

Periodically sediment will clog the outer pores of the ceramic 
cartridge and the water fl ow will decline. 

The cartridge should be 

cleaned when the fl ow rate has dropped to an unacceptable level.  
A new cartridge will typically deliver 1 gpm at 40 psi (45 litres at 
2.5 bar)

. The cartridge may be cleaned many times until cartridge 

gauge 703-4 can be passed over width of the ceramic.
1.  Shut off  valves before and after the fi lter unit and depress the vent 

button on top of the head until pressure is relieved. Remove the 
sump by lifting and rotating it counterclockwise an eighth turn to 
stop and lowering carefully.  Remove the cartridge (1M) by pulling 
and twisting gently downwards. Do not remove cartridge by 
unscrewing from adaptor (1007-0).

2.  To clean ceramic. (Note: Please wear rubber gloves) hold body 

of ceramic cartridge in the palm of your hand and gently scrub 
entire surface with abrasive screen cleaner (811-0) provided 
under running water.  Do not hold cartridge by adapter, as this 
may put undue strain on the fragile ceramic. Do not use soaps or 
detergents. Scrubbing removes trapped particulates along with 
part of the ceramic.

3.  Replace the cartridge into the fi lter base by pushing and turning 

gently to seal the o-ring.  Replace the sump over the fi lter head 
lugs and lock by rotating clockwise to stop. Open valves and 
check for leaks.

SOLDERLESS INSTALLATION    

  

For solderless installation use Rainfresh CK1P connector kit for inline installation (

Fig. 1

) or CK3 connector kit for undersink installation (

Fig. 2

). 

(sold separately)

INTRODUCTION

This Drinking Water System is equipped with a unique cleanable, reusable, Ceramic Cartridge (Model 
1M) that traps and kills harmful bacteria (ie. coliforms, E. coli, faecal coliforms) >99.99999%, traps cysts 
& protozoa (ie. cryptosporidium, Giardia lamblia) >99.9% and fi lters particulates as small as 0.3 micron 
(absolute). The activated carbon core within the ceramic further reduces tastes & odours.  It can be used 
on any municipal or untreated drinking water supply to deliver bacteriologically safe drinking water. 

INSTALLATION

DO NOT INSTALL AS A WHOLE HOUSE FILTER. 
THE CERAMIC CARTRIDGE WILL REDUCE PRESSURE AND FLOW RATE. 
Rated Service Flow - 1 gpm / 3.8 Lpm
NOTE:  This fi lter is to be used for one cold drinking water outlet only.  

It may be installed in-line as shown in 

Fig. 1

 or undersink as shown in 

Fig. 2

.

INSTALLATION CAUTIONS 

•  Maximum Working Pressure - 100 psi / 690 

kPa. If water pressure surges, or will at any time 

exceed the 100 psi / 6.9 bar / 690 kPa maximum, 

a pressure regulator must be installed before 
the fi lter. Recommended regulator setting is 75 
psi (517 kPa) or less) along with a water hammer 
arrestor to prevent damaging shocks caused by 
water hammer.

•  Maximum operating temperatuer: 100ºF / 38ºC
•  Important to allow at least 5 inches above and 

below the fi lter 
for clearance.

•  Do not install in direct sunlight.
•  Only use tefl on tape for fi tting connections into 

unit, DO NOT USE WICKING OR SEALER.

•  If water pipes are used to ground electrical 

system, install jumper wire (#4 gauge solid 
copper wire) across the fi lter unit.

•  Protect your unit from freezing - drain the unit if 

freezing 

temperatures exist.

NOTE: IF BRASS OR SOLDER TYPE FITTINGS 
ARE USED:
DO NOT 

use torch near plastic housing. All solder 

joints should be made before joining pipe to 
fi lter head.

DO NOT 

overtighten metal fi ttings into plastic 

fi lter head or it may crack. Hand tighten fi ttings 
plus one turn with wrench to give water seal.
System and installation shall comply with 
applicable state and local regulations.
