Step 2) Thecontrollerwillonlynofyyouwhenthereisafailure
modewherebythesolenoidmodule(andconnectedsolenoidvalve)
willbeacvated.OntheBLACKCOMB5.1system,thesolenoid
modulewillbeacvated(shungotheowofwater)uponLAMP
FAILURE(seeFig.7).Toremedythis,replacetheUVlampandrestart

youwillneedtoaddressthereasonforthislowUVcondionwhich
maybe due to a dirty UV sensorand quartz sleeve, a lamp that is

Step 4) To determine what posion the solenoid valve is currently in, the solenoid module
incorporatesthreelightson the circuit board (see Fig.9). When thesolenoid is in the OPEN
posionagreenlightwillappearonthecircuitboardbesidetheword“OPEN”.Whenthevalve
isCLOSED,aredlightwillappearonthecircuitboardbesidetheword“CLOSED”.Andwhenthe
solenoidisinanOVERRIDEposion,anamberlightwillappearonthecircuitboardbesidethe
word“OVERRIDEON”.

Boil Water Advisory: If any failure occurs on a BLACKCOMB UV system, the water
must not be used for human consumpon unl the system is returned to a safe operaonal
mode. If the water is used for human consumpon during this period, the water must be
boiled (minimum 20 minutes at a full boil) prior to consumpon.
EMERGENCY BYPASS
Inacasewherethesolenoidvalvehasbeenacvated(valveisclosedandnowaterisallowed
toow),thesolenoidmodulehastheabilitytobypassthesolenoidvalveincaseofan
emergencyneedofwater.Toiniatethisbypass,depressthebuonlabeled“OVERRIDE”
locatedinthelowerleporonofthecircuitboard(seeFig.10)
