MANUAL OVERVIEW

How To Use This Manual

This manual is designed to guide the installer through the

process of installing and starting the filter.

This manual is a reference and will not include every system

installation situation. The person installing this equipment

should have:

• Knowledge in water filter installation

• Basic plumbing skills

Icons That Appear In This Manual

WARNING:

Failure to follow this instruction can result in

personal injury or damage to the equipment.

NOTE: This will make the process easier if followed.

Inspection

Inspect the unit for damage or missing parts.

SAFETY INFORMATION

Electrical (361 Only)

• 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 and always on.

• To disconnect power, unplug the AC adapter from its

power source.

• Install an appropriate grounding strap across the inlet

and outlet piping of the water system to ensure proper

grounding is maintained.

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 tape should 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 of the plumbing should be done before

connecting to the valve. Excessive heat will cause interior

damage to the valve.

• Observe local drain line requirements.

• Do not use lead-based solder for sweat solder

connections.

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

valve fittings, plumbing, or the bypass.

• It is not recommended to use sealants on the threads.

Use plumber tape (PTFE) on all threads.

General

• Observe all warnings that appear in this manual.

• This system is not intended to be used for treating water

that is microbiologically unsafe or of unknown quality

without adequate disinfection before or after the system.

• Keep the unit 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 34°F (1°C)

and 120°F (49°C).

• Operating water temperature is between 34°F (1°C) and

100°F (38°C).

• Working water pressure range is 20 to 125 psi

(1.38 to 8.61 bar).

• Follow state and local codes for water testing.

• When filling media tank, do not open water valve

completely. Fill tank slowly to prevent media from exiting

the tank.

• Always make modifications to house plumbing first.

Connect to valve last.

• Plastic parts and O-rings may be damaged by heat and

solvents. When constructing plumbing connections, allow

heated parts to cool and protect parts from solvents.

Location Selection

Location of a water treatment system is important. The

following conditions are required:

• Level platform or floor.

• Constant electrical supply to operate the controller.

• Total minimum pipe run to water heater of ten feet (three

meters) to prevent backup of hot water into system.

• Local drain or tub for discharge as close as possible.

• Water line connections with shutoff or bypass valves.

• Room to access equipment for maintenance.

State of California to cause cancer or birth

defects or other reproductive harm.

2 • AUTOTROL 360/361 Filter Valves

Outdoor Locations

It is recommended that the equipment be installed indoors.

When the water conditioning system must be installed

outdoors, several items must be considered.

• Moisture — The valve and controller are rated for NEMA 3

locations. Falling water should not affect performance.

The system is not designed to withstand extreme humidity

or water spray from below. Examples are: constant heavy

mist, near corrosive environment, upwards spray from

sprinkler.

• Direct Sunlight — The materials used will fade or discolor

over time in direct sunlight. The integrity of the materials

will not degrade to cause system failures.

• Temperature — Extreme hot or cold temperatures may

cause damage to the valve or controller.

Freezing temperatures will freeze the water in the valve.

This will cause physical damage to the internal parts as

well as the plumbing.

• Insects — The controller and valve have been designed to

keep all but the smallest insects out of the critical areas.

EQUIPMENT INSTALLATION

If you are also installing a water softener, the softener should

be installed downstream of this system.

Grounding the Plumbing

It is important that the plumbing system be electrically

grounded. When a water treatment system is installed a

nonmetallic bypass valve may interrupt the grounding. To

maintain continuity, a grounding strap can be purchased at a

hardware store. When it is installed the strap will connect the

plumbing into the system to the plumbing leaving the system.

Water Line and Bypass Connection

Once you have selected your location check the direction of the

water flow in the main pipe.

A bypass valve system should be installed on all water

conditioning systems. The bypass valve system isolates the

filter from the water supply and provides untreated water to

service during routine maintenance and servicing procedures.

Drain Line Flow Control

The drain line flow control (DLFC) requires assembly

(Figures 4 and 5).

Install washer with printed

lettering facing the valve body.

Drain Line Connection

NOTE: Standard commercial practices are expressed here.

Local codes may require changes to the following

suggestions. Check with local authorities before

installing a system.

1. Use appropriate fittings to connect tubing to the DLFC

connection on valve.

2. The drain line may be elevated up to 6 feet (1.8 m) providing

the run does not exceed 15 feet (4.6 m) and water pressure

at the filter is not less than 40 psi (2.76 bar). Elevation can

increase by 2 feet (61 cm) for each additional 10 psi (.69 bar)

of water pressure at the drain connector.

3. Where the drain line is elevated but empties into a drain

below the level of the control valve, form a 7 inch (18 cm)

loop at the far end of the line so that the bottom of the loop

is level with the drain line connection. This will provide an

adequate siphon trap.

4. Secure the discharge end of the drain line to prevent it from

moving.

EQUIPMENT INSTALLATION continued

Right Way

Figure 6 Drain Line Connection

NOTE: Waste connections or drain outlet shall be designed

and constructed to provide for connection to the

sanitary waste system through an air gap of two

pipe diameters or one inch (22 mm), whichever is

larger.

WARNING:

Never insert drain line directly into a drain,

sewer line, or trap (Figure 6 Drain Line

Connection). Always allow an air gap between

the drain line and the wastewater to prevent

the possibility of sewage being back-siphoned

into the filter.

Electrical Connection (361 Only)

WARNING:

This valve and control are for dry location use

only unless used with a Listed Class 2 power

supply suitable for outdoor use.

The 361 controller operates on 12-volt alternating current

power supply. This requires use of the an AC adapter with your

system.

Make sure power source matches the rating printed on the AC

adapter.

STARTUP  360

The system will now need to be placed into operation. Please

review "INITIATING A CLEANING CYCLE" on page 7 before

attempting startup.

1. With the supply water for the system still turned off,

position the bypass valve to the “not in bypass” (normal

operation) position.

2. Turn the control knob counter-clockwise until the indicator

arrow on the valve body is lined up with "1" on the control

knob to start a cleaning cycle. The system will be in

backwash.

3. Filling the media tank with water:

A. With the system in backwash, open the water supply

valve very slowly to approximately the 1/4 open position.

Water will begin to enter the media tank. Air will begin

to be purged to drain as the media tank fills with water.

WARNING:

If opened too rapidly or too far, media may

be lost out of the tank into the valve or the

plumbing. In the 1/4 open position, you should

hear air slowly escaping from the valve drain

line.

B. When all of the air has been purged from the media

tank (water begins to flow steadily from the drain line),

open the main supply valve all of the way. This will purge

the final air from the tank.

C. Allow water to run to drain until the water runs clear

from the drain line. This purges any debris from the

media bed.

D. Turn off the water supply and let the system stand for

above five minutes to allow any trapped air to escape

from the media tank. Turn on the water supply after five

minutes.

4. Return the system to normal operation by turning the

control knob counter-clockwise until the indicator arrow is

lined up with "0" on the control knob.

The system is now fully operational.
