Introduction
Thankyou forpurchasing awaterconditionersystem
featuring the Series255 withamodel940 Control.
The Model940 Controlprovidesdependabletime
clock based operation. The Series255 valve
combinessimplicitywithreinforced NORYL*
construction toprovide an uncommonlyreliable
appliance. The inherent qualityofthe systemmeans
along lifeofefficient, trouble-free soft water. If
maintenancebecomesnecessary, the Series255/940
Controloffersaunique separation capability
illustrated inthe Servicesection ofthismanual.
Superiordesign
•Singlesynchronouselectricmotor providesall
the powerforthe clock and the operation ofthe
control.
•Electrical wiring isfactory assembled. System
cannot be connected incorrectly.
•Program clock 940 (timer)and 960 Demand
system are interchangeable. Bothunitsprovide
guest regeneration capability.
•System may beindexed manuallywith or
withoutpower toanyone ofitsserviceor
regeneration positions. Legend on timerfaceplate
indicatescontrolvalveposition.
•No moving partsin water stream meansno
closetolerancepartssubject tofouling. Thus, the
systemisespeciallyeffectiveon iron-bearing
water.
•No dynamicseals that couldcauseleakage
through wearorfatigue.
•Control acceptsNORYL*orbrass manifold or
modular bypass valve withoutmodification,
offering completeversatilityand easyplumbing
foranyinstallation.
•Brining control valve builtinto system
eliminatesneed foranybrine valve.
•Drain flow control isbuilt intothe valveto
controlbackwashand fast rinseflowrates.
•NORYLisatrademark ofGEPlastics.
SuperiorOperation
•Directacting system functionsindependentlyof
waterpressure. No pistonsordiaphragmsthat
requireaminimumwaterpressuretooperate.
•Five-cycleoperation providesfordownflow
service, up flowbackwash, downflowbrining,
downflowslowand fast rinse. Asixthposition is
included fortimed refill ofthe brine tank.
•Valve discs are held closed bywater pressure
and therefore, areleaktight. The sealing forces
areincreased asthe waterpressureisincreased.
Valveseatsareinaverticalposition, whichis
design position least vulnerabletoplugging.
•System operation cannotgetoutofphase or
sequence. The controlalwaysreturnstoafixed
serviceposition ofregeneration regardless of
whereinthe regeneration cycleit wasstarted.
•Bypass (unconditioned)water isautomatically
available during regeneration.
Installation
All plumbing and electricalconnectionsmust conform
tolocalcodes. Inspect the unit carefullyforcarrier
shortage orshipping damage.
LocationSelection
•Locateunit asclosetoadrainaspossible
•Ifsupplementary watertreating equipment is
required, makesurethat adequateadditional
spaceisavailable. Locatethe brine tankinan
accessibleplacesothat salt can easilybe added.
•Do not install anyunit closerthan 10ft (3m)of
piping between the outlet ofthe waterconditioner
and the inlet ofthe waterheater. Waterheaters
can transmit heat back downthe coldwaterpipe
intothe controlvalve. Hot watercan severely
damage the controller.
A10ft (3m)totalpipe run (including bends, elbows
etc) isareasonabledistancetoprevent hot water
damage. Apositivewaytoprevent hot waterfrom
flowing fromaheat sourcetothe conditioneristo

rated temperatureand pressuresafetyreliefvalve.
Alwaysconformtolocalcodes.
•Do not locatethe unit inan area wherethe temp
everfallsbelow34ºF (1ºC)orover120ºF (49ºC).
•Do not install the unit nearacidoracidfumes.
•Do not exposethe unit topetroleumproducts.

WaterLineConnection
Abypass valvesystemmust be installed toprovide
foroccasionswhen the waterconditionermust isby-
passed forhardwaterorforservicing. The most
common bypass systemsarethe AutotrolSeries156
Bypass Valve, Figure3, and plumbed-inglobe
valves, Figure4. Though botharesimilarinfunction,
the AutotrolBypass offerssimplicityand easeof
operation.
DrainLineConnection
The drainline dischargeswaterand brine during the
regeneration cycles. Typically, the line drainsintoa
floordrainorlaundry tube. Plumbthe drainline
according tolocalcodes, leaving aone ortwoinchair
gap between the end ofthe drainline and the open-
ing, Figure5.
Caution
Never connectthedrain lineinto adrain,
sewer lineortrap. Always allow an airgap
between thedrain lineand thewastewater
to preventthepossibilityofsewagebeing
back-siphoned into theconditioner.
The ideallocation forthe unit isaboveand not more
than 20ft (6.1m)fromthe drain. Forsuchinstallations,
using the appropriateadaptorfitting (not supplied),
connect 1/2in(1.3cm)plastictubing tothe drainline
connection located at the rearofthe control.
Ifthe unit islocated morethan 20ft (6.1m)fromthe
drain, use3/4in(1.9cm)tubing forrunsup to40ft
(12.2m). You mayelevatethe line up to6ft (1.8m)
providing the run doesnot exceed 15ft (4.6m)and the
waterpressureat the conditionerisnot less than
40psi(280kPa). You mayelevatean additional2ft
(61cm)foreachadditional10psi(70kPa)ofwater
pressure. When the drainline iselevated and empties
intoadrainwhichisbelowthe levelofthe control
valve, forma7inch(17cm)loop at the drainend of
the line sothat the bottomofthe loop islevelwiththe
drainline connection. Thisprovidesan adequate
siphon trap. Ifthe drainemptiesintoan overhead
sewerline, asink-type trap must be used.
Note: The aboveinstructionsreflect standard
commercialpractices. Localcodesmayrequire
different installation procedures.
BrineLineConnection
Install the brine tube and connect tothe fitting
connection located on the aircheck on the tank
adaptormodule, see Figure2.
Note: Makesurethat all fittingsand connectionsare
tight sothat prematurechecking doesnot takeplace.
Prematurechecking occurswhen the ball inthe air
check fallstothe bottombeforeall brine isdrawnout
ofthe brine tank. Refertothe Troubleshooting
section inthismanualforadditionalinformation.
BrineTankOverflow LineConnection
Inthe event ofamalfunction, the tankoverflow
connection directsoverflowtothe draininstead of
spilling on the floorwhereit couldcausewater
damage. Completethe following stepstoconnect the
overflowfitting tothe brine tank:
1.Locatethe fitting holeon the side ofthe brine
tank.

PlacingConditionerintoOperation
Afterthe waterconditioning systemisphysically
installed, werecommend that the conditionerbe
disinfected beforeit isused totreat potablewater.
Refertothe Disinfection ofWater Conditioners
section inthismanual. Completethe following steps
toplacethe conditionerintoservice.
1.Graspthe indicatorknob on the timer(Figure8)
and rotateit counterclockwise about 45°tothe
back- washposition. You mayfind it helpfulto
removethe rearcover(Figure10)and rotatethe
camshaft counterclockwiseat the sametime.
2.Fill the mineraltankwithwaterbyturning the
watersupplyoff and placing the bypass valve(s)
intothe "not inbypass"position. Open the water
supplyvalvevery slowlytoapproximatelythe 1/4
open position.
Caution
Ifthewater supplyvalve isopened too rapidly
ortoo far, resin may belost. In theBACKWASH
position, you should hear airescaping slowly
fromthedrain line.
3.When all the airispurged fromthe tank(water
beginstoflowsteadilyfromthe drain), slowly
open the mainsupplyvalveall the way. Allowthe
watertorun intothe drainuntil the waterappears
clear. Turnoff the watersupplyand wait forabout
fiveminutestoallowall trapped airtoescape
fromthe tank.
4.Add watertothe brine tank(initialfill). Witha
bucket orhose, add approximately4gallons(15
litres)ofwatertothe brine tank.
5.Tostart up the unit: makesurethe watersupply
valveisinthe full open position. Carefullyrotate
the indicatorknob, Figure8, counterclockwise
until the indicatorpointsdirectlytothe centreof
the REFILL position and holdthereuntil the air
check (Figure7), fillswithwaterand waterflows
through the brine line intothe brine tank. Do not
run the waterintothe brine tankformorethan
one ortwominutes.
Rotatethe indicatorknob counterclockwise until
the indicatorpointstothe centreofthe BRINE/
SLOWRINSE position.
Check the waterisbeing drawnfromthe brine
tank. The waterlevelinthe brine tankwill recede
very slowly. Observethe waterlevelforat least
three minutes. Ifthe waterleveldoesnot recede,
ifit goesup, orifairentersthe aircheck sight
glass and the ball fallsand seats, refertothe
Troubleshooting section inthismanual.
