SYSTEM PROTECTION - COMMISSIONING
14. System protection
Failuretoprotectthesystemwillinvalidatethemanufac-
turer’swarranty.Afterthesystemhasbeeninstalledthe
cleansingandinhibitingproceduremustbecarriedoutas
follows:
Procedure:
1. Fill the system with cold mains water to the recom-
mendedpressure1.5barandcheckforleaks,thendrain
thesystemthoroughlymakingsurealldraincocksare
fullyopenandthatthesystemiscompletelydrained.
2. Add Fernox Heavy Dutyrestorer through theheader
tankorviallingloopattherecommendeddose.One
bottlemustbeusedasaminimumperdwelling.Ifyou
areunsureofthecorrectdoserate,contactFernox.
3. Re-llthesystemandcirculatetheHeavy-DutyRestorer
priortotheboilerbeingredup,thencommissionthe
systeminthenormalway.Thecleansingagentmust
beinthesystemforaminimum1hourwiththesystem
at normal operating temperature.A longer period of
timewouldbemorebenecialtothecleansingprocess
especiallyifexcessuxwasused.
4. Drainandushthesystemthoroughlytoremovethe
cleaningagentandanydebrisorcontaminant.Thisisa
criticalpartofthecleaningprocessandmustbecarried
outcorrectly.Usearinsetestmeter(TDS),suchasthe
FernoxCTM.Thereadingmustbewithin10%ofthe
mainsppmvalue.
5. ThenaddtheFernoxProtector(CopalMB1orSuper
concentrate). This will protect against the formation
ofscale,corrosionandmicrobiologicalgrowths.Itis
crucialhowever,thatfortheprotectortoworkcorrectly,
thesystemmustbeproperlycleansedandushed.
6. ThelabelincludedwithintheFernoxProtectorcarton
shouldbecompletedandattachedadjacenttotheboiler.
7. Werecommendinhibitorlevelsarecheckedonanan-
nualbasis(usuallyduringtheservice)orsoonerifthe
systemcontentislost.Thisshouldbecarriedoutusing
aFernoxinhibitorTestKit.

1. Ensuresystemislledwithwater&vented.
2.
Checkiftheappropriatesysteminstallationpressureis
reached
3. Switchtheboileron&setexternalcontrolstocallfor
heat.
4. Checkthepumpissettothecorrectmode(seetable
below).Todothis,press buttonfornomorethan2
seconds.TheLED’sshouldsignalanoperatingmode
attheplacepointedbyarrow.
5. IftheLEDsaresignalingadifferentoperatingmodethan
recommendedinthetablebelow,settheappropriate
modeaccordingtothefollowinginstructions:press 
buttonforlongerthan2seconds,butlessthan10sec-
onds(LED’swillstarttoash),thepumpthenswitches

If the pump has detected one or more alarms, the bicolored LED
1 switches from green to red. When an alarm is active, the LEDs
indicate the alarm type as defined in the table below. If multiple
alarms are active at the same time, the LEDs only show the error
with the highest priority. The priority is defined by the sequence
of the table. When there is no active alarm anymore, the user in-
terface switches back to operation mode.
