How to replace the UV Lamp and clean Quartz Dome:
1.
Unplug UV unit from electrical outlet and turn off supply valve before the unit. Open a faucet to depressurize the UV system and turn off the
valve at the UV outlet to isolate UV unit. CAUTION: The lamp end can be very hot. Wait several minutes for the lamp to cool down.
2.
Unscrew the ground nut and remove the ground wire (green wire with yellow stripes).
3.
Loosen the screw on the lamp connector cover and remove cover from the gland nut.
4.
Carefully slide UV lamp slightly out of chamber and hold the lamp end with one hand. Gently pull off the connector with your other hand to
disconnect the lamp completely. Slowly remove lamp from the disinfection chamber completely.
5.
Remove the quartz dome by loosening the gland nut and carefully extracting from the unit. Remove dome absolutely vertically from its
position until the other end comes out. CAUTION: If you bend the dome mid-way, it can break easily and pieces of quartz can fall into the UV
chamber. Do not lose the spring.
6.
Remove & discard used dome O-ring. Clean dome gently with a vinegar solution or a household scale-removal product.
Do not use abrasive
pads
. A soft cloth or paper towel is recommended.
7.
Using a small pointed tool carefully take the gland-nut O-ring out of the
gland nut. Take care not to scratch the gland nut.
8.
A dome O-ring (thicker) and gland nut O-ring (thinner) are included
with the replacement lamp. Slide gland nut O-ring into the internal groove
of the gland nut.
9.
Follow instructions 7 to 15 in previous section “Installing the UV Unit”.
Do not plug in ballast yet.
10.
Depress timer button while reconnecting ballast
to electrical outlet
and keep the button depressed until the ballast emits a solid three-second
beep. This will re-set the lamp-change-timer to zero and the 3-second beep
will confirm that the re-set was successful.
Winterizing Your System:
To winterize the system, unplug the unit first. Drain the pre-filter by removing
the sump and dump the water, then drain the UV chamber of all water.
PROBLEM
PROBABLE CAUSE
SOLUTION
Leak at gland nut
Gland nut is loose or O-ring defective
Hand-tighten gland nut & replace O-ring(s)
Condensation outside the UV chamber
High humidity in the environment
This is normal if humid conditions exist.
Install dehumidifier to protect ballast. Protect
flooring below UV
Hot water coming out of taps/faucets
Water inside UV unit becomes hot after long
periods of non-use. You may have oversized
the unit for the home
To prevent scalding, before using water after
periods of non-use such as overnight, flush
water for about 2 minutes. Install a temper-
ature controlled purge valve on the UV outlet
UV lamp ends seem burnt after
some time
This is normal
As long as the UV lamp lights, a little burn
mark at the ends is normal and there is no
need to replace the UV lamp
