Troubleshooting
PROBLEM CAUSE CORRECTION
1. Pressure Drop A. Sediment pre-filter clogged
B. Flow regulator
A. Replace filter cartridge with appropriate 5
micron cartridge.
Note: check source water supply as fluctua-
tions may occur in source pressure
B. Flow regulator will result in pressure drop
when approaching full flow.
2. High Bacteria Counts A. Quartz sleeve is stained or dirty
B. Change in feed water quality
C. Contamination in water lines after
UV system
D. Possible break-through of sediment
through pre-filter
A. Clean sleeve with scale cleaner and elimi-
nate source of staining problem (ie. soften
hard water, see page 5-6).
B. Have source water tested to ensure that
water quality is still within allowable limits for
this system.
C. It is imperative that effluent water stream be
shocked with chlorine (bleach) before water
leaves UV system - disinfection system must
have a bacterial free distribution system to
work effectively (see page 4).
D. Have source water tested for turbidity - may
need stepped filtration in order to catch all
sediment entering water system (20 micron
filter followed by UV system).
3. Heated Product
Water
A. Common problem caused by infre-
quent use of water
A. Run water until it returns to ambient temper-
ature.
4. Water Appears Milky A. Caused by air in the water lines A. Run water until air is purged.
5. Unit Leaking Water A. Problem with o-ring seal (on gland
nut and/or UV sensor)
B. Condensation on reactor chamber
caused by excessive humidity and
cold water
C. Inadequate inlet/outlet port connec-
tions
A. Ensure o-ring is in place, check for cuts or
abrasions, clean o-ring, moisten with
water/lubricant and re-install, replace if nec-
essary.
B. Check location of disinfection system and
control humidity.
C. Check thread connections, reseal with
Teflon ® tape and re-tighten.
6. System Shutting
Down Intermittently
A. Interrupted power supply A. Ensure system has been installed on its own
circuit, as other equipment may be drawing
power away from UV (ie. pump or fridge).
UV system should not be installed on a cir-
cuit which is incorporated into a light switch.
7. Lamp Failure Alarm
On - New Lamp
A. Loose connection between lamp and
connector
B. Moisture buildup in connector may
keep lamp and connector from mak-
ing a solid connection
A. Disconnect lamp from connector and recon-
nect, ensuring that a tight fit is accom-
plished.
B. Eliminate chance of any moisture getting to
the connector and/or lamp pins.
