TROUBLESHOOTING GUIDE

Caution: When performing any work on the disinfection system unplug the unit first and never look directly at the burning UV lamp.

SYMPTOM POSSIBLE CAUSES REMEDY

• replace filter cartridge with

appropriate five micron cartridge,

PRESSURE DROP • the sediment pre-filter is clogged Note: check source water supply as fluctuations may occur in source pressure

			•	clean sleeve with scale cleaner
	•	quartz sleeve is stained or dirty		and eliminate source staining
				problem
	•	the UV lamp is spent	•	replace UV lamp
HIGH BACTERIA	•	change in feedwater quality	•	have the source water tested to
				ensure it is still within the allowable
COUNTS				parameters for use with this unit
			•	it is imperative that the effluent
				water stream be shocked with
	•	contamination after the disinfection		chlorine after the water leaves the
				disinfection system - the disinfection
		system
				system must have a bacteria free
				distribution system to work
				effectively
WARM PRODUCT	•	common problem caused by	•	run water until it returns to ambient
WATER		infrequent use		temperature
WATER APPEARS	•	caused by air in the water lines	•	run water until air is purged
“MILKY”
	•	problem with o-ring seals (on gland	•	ensure the o-ring is in place, check
				for cuts or abrasions, clean o-ring,
		nuts and/or sensor probe on
				moisten with water and re-install,
		monitored units)
				replace if necessary (Part# OR-212)
UNIT LEAKING WATER
	•	condensation on reactor chamber	•	check location of disinfection
		caused be excessive humidity		system and control humidity
	•	inadequate inlet / outlet port	•	check thread connections, reseal
		connections		with Teflon™ tape and re-tighten
