7.1

Cleaning the quartz glass sleeve

Depending on the water quality, the quartz sleeve
may require periodic cleaning. At a minimum, the
quartz sleeve should be cleaned on an annual basis.
The steps 1-11 outline a basic cleaning procedure.
ATTENTION:
UV lamps are very hot and must cool down approx.
5 minutes.
1: If a by-pass assembly is installed, shut the inlet
valve off to prevent water flow through the UV
system. Otherwise, turn off the main water inlet
valve (and/or turn off the water pump).
2: Plug out the power plug of UV system from
electrical outlet.
3: Release the remaining water pressure by ope-
ning a downstream faucet and then close the
outlet shut-off valve (if any is present). If there
is no outlet shut-off valve, expect water to drain
from the system as the head pressure in the
system will cause the water to flow back down.
4: Remove the captive ground screw from the
ground lug on the UV reactor.
5: Remove the lamp connector from the reactor
(gland nut) by pushing the lamp connector in
and turning it ¼ turn counterclockwise. Now
disconnect the lamp connector from the UV
lamp.
6: Being careful to touch only the ceramic ends,
remove the lamp out of the reactor!
7: Unscrew the gland nut from the reactor expo-
sing the end of the quartz glass sleeve.
8 Now remove the quartz glass sleeve together
with the o-ring out of the reactor by gently twis-
ting and pulling the quartz glass sleeve.
9: U sing a soft, fiber-free cleaning cloth or mi-
crofibre towel wipe the sleeve down using a
commercial scale cleaner. This removes scaling
or iron deposits that may be on the outside of
the quartz glass sleeve. Be careful not to get
any moisture or liquids inside of the quartz glass
sleeve.
10: Dry the quartz glass sleeve with a separate
microfibre cloth.
11: Replace the o-ring and slide the sleeve back
into the reactor following step 6 from chapter 8.

Cleaning the UV sensor

Depending on the water quality, the UV sensor may
require periodic cleaning. At a minimum, the UV
sensor should be cleaned on an annual basis. The
following steps outline a basic cleaning procedure.
1: If a by-pass assembly is installed, shut the inlet
valve off to prevent water flow through the sys-
tem. Otherwise, turn off main water inlet valve
(and/or turn off the water pump).
2: Plug out the power plug of UV system from
electrical outlet.
3: Release the remaining water pressure by
opening a downstream faucet and then close
the outlet shut-off valve (if any is present). If
there is no outlet shut-off valve, expect water
to drain from the system as the head pressure
in the system will cause the water to flow back
down.
4: Place an collecting container under the reactor
to catch any water that may flow out of the
reactor during the removal of the UV sensor.
5: Unscrew (counterclockwise) sensor nut from
the reactor and pull the sensor slowly out of the
sensor port.
6: H olding the sensor in your hand wipe the flat
portion (sensor face) of the sensor with isopro-
pyl alcohol using a clean microfibre cloth.
7: Replace the new sensor by following step 8 from
chapter 7, page 13 of this manual.
