All plumbing and electrical connections must conform
to local codes.
Inspect unit carefully for carrier shortage or shipping
1. The distance between the unit and a drain should be
as short as possible.
2. If it is likely that supplementary water treatment
equipment will be required, make certain adequate
additional space is available.
3. Do not install any unit closer to a water heater than
a total run of 10 feet (3 m) of piping between the
outlet of the conditioner and the inlet to the heater.
Water heaters can sometimes overheat to the
extent they will transmit heat back down the cold
pipe into the unit control valve.
Hot water can severely damage the conditioner. A
10-foot (3-m) total pipe run, including bends,
elbows, etc., is a reasonable distance to help
prevent this possibility. A positive way to prevent
hot water flowing from heat source to the
conditioner, in the event of a negative pressure
situation, is to install a check valve in the soft
water piping from the conditioner. If a check valve
is installed, make certain the water heating unit
is equipped with a property rated temperature
and pressure safety relief valve. Also, be
certain that local codes are not violated.
4. Do not locate unit where it or its connections
(including the drain) will ever be subjected to room
temperatures under 34oF (1oC) or over 120oF
5. Do not install unit near acid or acid fumes.
Water Line Connection
The installation of a bypass valve system is
recommended to provide for occasions when the water
conditioner must be bypassed for hard water or for
The most common bypass systems are the Autotrol
Series 1265 bypass valve (Figure 1) and plumbed-in
globe valves (Figure 2). Though both are similar in
function, the Autotrol Series 1265 bypass offers
simplicity and ease of operation.
Drain Line Connection
Note: Standard commercial practices are expressed
here. Local codes may require changes to the following
1. Ideally located, the unit will be above and not more
than 20 feet (6.1 m) from the drain. For such
installations, using an appropriate adapter fitting,
connect 1/2-inch (1.3-cm) plastic tubing to the drain
line connection of the control valve.
2. If the backwash flow rate exceeds 5 gpm
(22.7 Lpm) or if the unit is located more than 20 feet
(6.1 m) from drain, use 3/4 -inch (1.9-cm) tubing for
runs up to 40 feet (12.2 m). Also, purchase
appropriate fitting to connect the 3/4-inch tubing to
the 3/4-inch NPT drain connection.
3. If the unit is located where the drain line must be
elevated, you may elevate the line up to 6 feet
(1.8 m) providing the run does not exceed 15 feet
(4.6 m) and water pressure at conditioner is not less
than 40 psi (2.76 bar). You may elevate an
additional 2 feet (61 cm) for each additional 10 psi
4. 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
5. Where the drain empties into an overhead sewer
line, a sink-type trap must be used.
IMPORTANT: Never insert drain line into a drain, sewer
line or trap. Always allow an air gap between the drain
line and the wastewater to prevent the possibility of
sewage being back-siphoned into the conditioner.
Note: Standard commercial practices have been
expressed here. Local codes may require changes to
Placing Conditioner into Operation
After all previous steps have been completed the unit is
ready to be placed into operation. Follow these steps
1. Remove control valve cover.
Note: The following steps will require turning the
indicator knob (Figure 4 and Figure 5) or the cycle
indicator (Figure 7) to various positions. Manually
rotate the camshaft COUNTERCLOCKWISE only
until indicator knob and cycle indicator points to
desired position. (See manual regeneration
sections for each control’s manual operation.)
2. Rotate indicator knob or cycle indicator
COUNTERCLOCKWISE until it points directly to
the word BACKWASH.
3. Fill media tank with water.
a. With water supply off, place the bypass valve(s)
into the "service” position.
b. Open water supply valve very slowly to
approximately the 1/4 open position.
IMPORTANT: If opened too rapidly or too far, media
may be lost. In the 1/4 open position, you should hear
air escaping slowly from the drain line.
c. When all of the air has been purged from the
tank (water begins to flow steadily from the
drain), open the main supply valve all the way.
d. Allow water to run to drain until clear.
e. Turn off water supply and let the unit stand for
about five minutes. This will allow all trapped air
to escape from the tank.
4. Place the conditioner into operation.
a. Advance the indicator knob or cycle indicator
COUNTERCLOCKWISE to the SERVICE
position and run water from a nearby faucet
until the water is clear.
100 VAC, 115 VAC, and 230 VAC units: Remove twist
tie from the power cord and extend cord to its full
length. Make sure the power source matches the rating
printed on the control. Be certain a wall switch does not
control the outlet.
12 VAC: Connect the plug of the transformer (supplied)
secondary cable to the mating socket at the rear or
bottom of the timer housing. Be certain the transformer
is secure and is plugged into a power source of correct
voltage that is not controlled by a wall switch.
