4. Slowly open the feed water supply valve.
5. Open all downstream faucets. Keep faucets open until a
chlorine smell is detected at each faucet, then close
faucets.
NOTE:
Water lines downstream from UV housing must be
disinfected to destroy any bacteria that might
remain in the pipes.
6. Verify disinfection solution has reached every water outlet
downstream of UV system
. Solution must remain in the
system for at least four hours.
7. Open outlet valve and let water flow for 5 minutes to flush

ROUTINE MAINTENANCE
FILTER REPLACEMENT PROCEDURE
1. Perform Cleaning Procedure (Page 14, step1-11).
NOTE:
Do not remove protective plastic bag from filters.
Open bottom of bag only enough to expose
bottom of filter.
NOTE:
Refer to Exploded Schematic for your system to
ensure each filter is installed in the correct position.
NOTE:
For UVB and UV1 Models only:
Refer to the
Exploded Schematic to ensure proper position of
EPCB
Sleeve removed in Cleaning Procedure.
2. Install the filters into the appropriate sump. Hold filter by
its protective plastic bag and insert the filter into the sump.
CAUTION:
For UVBB Model only:
Be sure sump with
metal liner is installed onto UV head.
CAUTION:
TIGHTEN SUMPS BY HAND ONLY. Do not use
tools as they will over-tighten and may damage
sump. Take care not to cut or pinch “O” rings or
gaskets.
Use
sump
wrench for removal only.
3. Slide bag from filter and discard. Replace each sump as
each filter is installed.
4. Plug system into electrical outlet. Turn on water supply
and check for leaks. Flush system for several minutes to
remove carbon fines.
ROUTINE MAINTENANCE
UV LAMP REPLACEMENT PROCEDURE
NOTE:
Refer to individual System Assembly and Activation
Procedures to identify specific components matching
the descriptions shown in this procedure.
1. Disconnect system from electrical outlet.
2. Shut feed water supply valve and open downstream faucet
to relieve system pressure.
CAUTION:
Do not attempt to remove sumps until water
flow stops. This reduces pressure inside the
system so sumps may be safely removed.
CAUTION:
Use care when sanitizing UV head. Do not get
the UV control module or connectors wet.
3. Remove sump from UV head and set aside.
CAUTION:
Do not touch quartz sleeve or UV lamp with bare
hands. Fingerprints will reduce the effectiveness
of
the
light.
WARNING: Do Not Attempt to Remove Quartz Sleeve.
Damage to system and personal injury may
occur
if
the
sleeve
is removed incorrectly.
Contact your dealer if quartz sleeve is broken or
needs
replacement.
4. Clean quartz sleeve carefully using vinegar to remove
hardness. Do not use abrasive materials. Rinse sleeve
thoroughly with clean potable water. Replace any sleeve
that is damaged or that will not come completely clean.
5. Gain access to UV lamp:
a.
For UVB, UV20, and UVBB Models only.
Remove
UV Control Module (Item 10) from Mounting Bracket
(Item 6, 6A, 6b) by removing four Screws (Item 11).
b.
For UV1 Model only:
Loosen Screw (Item 9)
securing slotted side of UV Lamp Retainer (Item 7).
Remove
other
screw
securing UV lamp retainer to UV
head. Rotate bracket away from UV lamp. Remove
and slide Finish Cap (Item 12) on cable towards UV
control.
6. Remove UV lamp from system being careful not to break
UV lamp or dislodge quartz sleeve:
a.
For UVB and UV20 Models only:
Remove UV
control module with UV lamp by gently lifting control
module straight up from mounting bracket. Grasp UV
lamp firmly and remove lamp from the four-pin socket.
b.
For UVBB Model only:
Remove UV control module
with UV lamp by lifting the control module straight up
from mounting bracket. The four-pin socket is
attached to the UV control module by a short cable
that allows for correct insertion depth. Grasp UV
lamp and four-pin socket firmly and separate lamp
from
connector.
c.
For UV1 and Addon Models Only:
Remove UV
lamp by gently lifting the cable connecting the four-pin
socket to the UV lamp. Grasp UV lamp and four-pin
socket firmly and separate lamp from connector.
During replacement, be sure UV lamp is inserted as
far as possible into the quartz sleeve.
NOTE: T
he inside of quartz sleeve must be completely dry
before installing the replacement UV lamp.
NOTE:
Hold replacement UV lamp by the ceramic ends only.
Do not touch the glass. Clean glass with isopropyl
alcohol
if
necessary.
7. Install the replacement UV lamp by reversing
steps 5 and 6 of this procedure.
