Introduction
Thank you for purchasing a water conditioner system
featuring the Series 255 with a model 940 Control.
The Model 940 Control provides dependable time
clock based operation. The Series 255 valve
combines simplicity with reinforced NORYL *
construction to provide an uncommonly reliable
appliance. The inherent quality of the system means
a long life of efficient, trouble-free soft water. If
maintenance becomes necessary, the Series 255/940
Control offers a unique separation capability
illustrated in the Service section of this manual.
Superior design
•
Single synchronous electric motor provides all
the power for the clock and the operation of the
control.
•
Electrical wiring is factory assembled. System
cannot be connected incor rectly.
•
Program clock 940 (timer) and 960 Demand
system are interchangeable.
Both units provide
guest regeneration capability.
•
System may be indexed manually with or
without power
to any one of its service or
regeneration positions. Legend on timer faceplate
indicates control valve position.
•
No moving parts in water stream means no
close tolerance parts subject to fouling. Thus, the
system is especially effective on iron-bearing
water.
•
No dynamic seals that could cause leakage
through wear or fatigue.
•
Control accepts NORYL* or brass manifold or
modular bypass valve without modification,
offering complete versatility and easy plumbing
for any installation.
•
Brining control valve built into system
eliminates need for any brine valve.
•
Drain flow control is built into the valve to
control backwash and fast rinse flow rates.
•
NORYL is a trademark of GE Plastics.
Superior Operation
•
Direct acting system functions independently of
water pressure. No pistons or diaphragms that
require a minimum water pressure to operate.
•
Five-cycle operation provides for down flow
service, up flow backwash, down flow brining,
down flow slow and fast rinse. A sixth position is
included for timed refill of the brine tank.
•
Valve discs are held closed by water pressure
and therefore, are leak tight. The sealing forces
are increased as the water pressure is increased.
Valve seats are in a vertical position, which is
design position least vulnerable to plugging.
•
System operation cannot get out of phase or
sequence. The control always returns to a fixed
service position of regeneration regardless of
where in the regeneration cycle it was started.
•
Bypass (unconditioned) water is automatically
available
during regeneration.
Installation
All plumbing and electrical connections must conform
to local codes. Inspect the unit carefully for carrier
shortage or shipping damage.
Location Selection
•
Locate unit as close to a drain as possible
•
If supplementary water treating equipment is
required, make sure that adequate additional
space is available. Locate the brine tank in an
accessible place so that salt can easily be added.
•
Do not install any unit closer than 10ft (3m) of
piping between the outlet of the water conditioner
and the inlet of the water heater. Water heaters
can transmit heat back down the cold water pipe
into the control valve. Hot water can severely
damage the controller.
A 10ft (3m) total pipe run (including bends, elbows
etc) is a reasonable distance to prevent hot water
damage. A positive way to prevent hot water from
flowing from a heat source to the conditioner is to
install a check valve in the soft water piping from the
conditioner. If a check valve is installed, make sure
that the water-heating unit is equipped with a properly
rated temperature and pressure safety relief valve.
Always conform to local codes.
•
Do not locate the unit in an area where the temp
ever falls below 34ºF (1ºC) or over 120ºF (49ºC).
•
Do not install the unit near acid or acid fumes.
•
Do not expose the unit to petroleum products.
