Installation
All plumbing and electrical connections must conform to
local codes.
Inspect unit carefully for carrier shortage or shipping
damage.
This system is not intended to be used for treating water
that is microbiologically unsafe or of unknown quality
without adequate disinfection before or a er the system.
Location Selection
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. Since salt must be added periodically to the brine
tank, the location should be easily accessible.
4. 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 fl owing from heat
source to the conditioner, in the event of a negative
pressure situation, is to install a check valve in the so
water piping from the conditioner. If a check valve
is installed, make certain the water heating unit is
equipped with a properly rated temperature and
pressure safety relief valve. Also, be certain that
local codes are not violated.
5. Do not locate unit where it or its connections
(including the drain and overfl ow lines) will ever be
subjected to room temperatures under 34
o
F (1
o
C) or
over 120
o
F (49
o
C).
6. Do not install unit near acid or acid fumes.
7. The use of resin cleaners in an unvented enclosure is
not recommended.
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 servicing.
Drain Line Connection
Note: Standard commercial practices are expressed
here. Local codes may require changes to the following
suggestions.
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 fi  ing,
connect 1/2-inch (1.3-cm) plastic tubing to the drain
line connection of the control valve.
2. If the backwash fl ow 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
fi  ing 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 (0.69 bar).
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

Figure 1: Autotrol Series 1265 bypass valve
The most common bypass systems are the Autotrol Series 1265
bypass valve (1) and plumbed-in globe valves (2). Though both
are similar in function, the Autotrol Series 1265 bypass offers
simplicity and ease of operation.
