MANuAl oVErVIEW

How to use this Manual

This installation manual is designed to guide the installer

through the process of installing and starting conditioners

featuring the 400 series controllers.

This manual is a reference and will not include every system

installation situation. The person installing this equipment

should have:

• Training in the 400 series controllers and water

conditioner installation

• knowledge of water conditioning and how to determine

proper control settings

• basic plumbing skills

• The directional instructions "left" and “right" are

determined by looking at the front of the unit.

SAFEtY INForMAtIoN

Electrical

There are no user-serviceable parts in the AC adapter,

motor, or controller. In the event of a failure, these should be

replaced:

• All electrical connections must be completed according

to local codes.

• Use only the power AC adapter that is supplied.

• The power outlet must be grounded.

• To disconnect power, unplug the AC adapter from its

power source.

Mechanical

• Do not use petroleum based lubricants such as

petroleum jelly, oils, or hydrocarbon based lubricants.

Use only 100% silicone lubricants.

• All plastic connections should be hand tightened.

Plumber's tape may be used on connections that do not

use an O-ring seal.

Do not use pliers or pipe wrenches.

• All plumbing must be completed according to local

codes.

• Soldering near the drain line should be done before

connecting the drain line to the valve. Excessive heat will

cause interior damage to the valve.

• Do not use lead-based solder for sweat solder

connections.

• The drain line must be a minimum of 1/2" diameter. Use

3/4" pipe if the backwash flow rate is greater than 5 GPM

(18.9 Lpm) or the pipe length is greater than 20 feet (6

m).

• Do not support the weight of the system on the control

valve fittings, plumbing, or the bypass.

General

• keep the media tank in the upright position. Do not turn

on side, upside down, or drop. Turning the tank upside

down will cause media to enter the valve.

• Operating ambient temperature is between 34ºF (1ºC)

and 120ºF (49ºC).

• Operating water temperature is between 34ºF (1ºF) and

100ºF (38ºC).

• Working water pressure range is 20 to 125 psi (1.38

to 8.61 bar). In Canada the acceptable working water

pressure range is 20 to 100 psi (1.38 to 6.89 bar).

• Use only regenerant salts designed for water softening.

Do not use ice melting, block, or rock salts.

• Follow state and local codes for water testing. Do not use

water that is micro-biologically unsafe or of unknown

quality.

• When filling media tank, do not open water valve

completely. Fill tank slowly to prevent media from exiting

the tank.

• When installing the water connection (bypass or

manifold) connect to the plumbing system first. Allow

heated parts to cool and cemented parts to set before

installing any plastic parts. Do not get primer or solvent

on O-rings, nuts, or the valve.
