  Shut off electrical power or gas valves supplying water heater(s).

Note to installer: Tank may be buried 2/3 under ground..

•

  Turn off the main water supply to the home and open an inside    

faucet to relieve any pressure within the plumbing system.

•

Place the bypass valve in the upflow service position. 

  See bypass valve modification detail pictured left.

•

  Connect the cold water supply to the inlet of the 

H2 ZERO

®

system. NOTE: The 

H2 ZERO

®

 system operates in the upflow 

mode which is opposite of a traditional filtration / softener.  

See  Bypass Valve Modification below.

•

  Connect a hose to the 

outlet

 for the purpose of draining excess carbon.

•

  Turn the water back on to the house. Slowly open the supply 

valve to the 

H2 ZERO

®

system. Allow the tank to fill with water.  

Repeat these steps three times*

Carbon tank must be flushed individually.  Do not attempt to flush 

the carbon tank while it is connected to tank 2.

•

  Backwash tank 1 for 20 minutes in the upflow service position.

•

  Backwash in the downflow service position for 10 minutes.    

•

  Close the valve to the outlet hose drain and let system stand  

pressurized for 10 minutes.

*If time permits you can soak the system for 48 hrs instead of flushing.

•

  Connect the outlet of the 

H2 ZERO

®

 system to the cold water    

supply to the house.

•

  Open the supply valve to the 

H2 ZERO

®

 system.

•

  Open hot and cold faucets downstream from the 

H2 ZERO

®

system to relieve any air from the plumbing system and water 

heaters.  Introduce the water inside the 

H2 ZERO

®

 to home, flush 

for 5 minutes.  System is now installed and ready for use.  

Close the faucets.

As shipped, the bypass is set-up for downflow use. The arrow 

shape of the handles points in the wrong direction for UP-flow 

use. To convert it to upflow use, pull up on the red handles 

until they come off. Rotate the handle 180° and put it back 

on the valve stem.

Installation and Start-up

1.

 Turn off water heater(s).

2.

 Turn off the main water supply to the home and open an

inside faucet to relieve any pressure within the plumbing sys-

tem.

3.

 Place the system in the desired location. Make sure that the

location is level and sturdy enough to support the weight of

the wetted system.

4.

 Place the bypass valve in the up flow service position. See

below Bypass Valve Modification Detail.

5.

 Connect the cold water supply to the inlet of the 

H2 ZERO

®

system. NOTE: The 

H2 ZERO

®

 system operates in the

UP-flow mode which is opposite of a conventional softener.

Follow the plumbing diagram in Figure 3.

6.

 Install a supply valve (user supplied) in the supply line and

close it.

7.

 Place a bucket under the outlet port or run a line from the

outlet port to a drain.

8.

 Turn the water back on to the house. Slowly open the sup-

ply valve to the 

H2 ZERO

®

 system. Allow the tank to fill with

water. Close the supply valve when a steady stream of

water 

comes out of the outlet port. If the outlet is flowing

into a 

bucket, water could splash on nearby objects. If this

threatens the safety, value, structure, or appearance of these

objects, protect/remove them or use the outlet hose to drain

option.

9.

 Close the inside faucet.

10.

 Connect the outlet of the 

H2 ZERO

®

 system to the cold

water supply to the house.

11.

Open the supply valve to the 

H2 ZERO

®

 system.

12.

 Open hot and cold faucets downstream from the 

H2 ZERO

®

system to relieve any air from the plumbing system and

water heaters. Then close the faucets.

13.

Check for leaks. Repair as needed.

14.

The system is now ready for service.
