pins. First remove the U-clip from both sides, the remove the back reflector by
gently pushing the tab out from the alignment pins. To remove the front
reflector, the UV sensor can be removed. If the left lamp is removed, the front
reflector can be manipulated out leaving UV sensor in place.
Step 5:
Examine the quartz sleeve both inside and out. If it is clean, no
disassembly is required. Replace the reflectors &/or side panels, lamps and
covers. Plug in the unit and operate as normal. If the quartz sleeve is dirty on
the outside, proceed to wipe it down with a clean lint-free cloth and rubbing
alcohol to remove the dirt. If the quartz sleeve is dirty on the inside, proceed
with in-place cleaning or disassembly.
Caution:
The quartz sleeve can break or chip if mishandled. Always handle it
with care and keep it in a safe place if it is removed from the unit. Do not strike
the quartz sleeve with any tool, since even the smallest chip can cause it to
break under pressure.
In-place cleaning
Note that numbers in parentheses refer to Figure 4B.
This procedure will clean the quartz without its removal from the unit. This is a
quick and easy procedure that works well in most cases.
Step 1:
Fill a bucket or container with water before shutting off the water supply
since you will need the water later to clean the quartz sleeve (4). A squeeze
bottle is useful for applying water or cleaning solution
to the inside of the quartz
sleeve.
Step 2:
Open the unit and remove the lamps and reflectors (see Determining
the Need for Cleaning).
Step 3:
Place another bucket under the unit and drain the unit until there is
about 1” (3cm) of water left in the quartz sleeve (see Draining the Unit).
Step 4
: Disconnect the
top
hose from the plumbing side (not the unit side but
other end).
Step 5
: Add about 2 oz. (60cc) of cleaning solution to the top hose. The
cleaning solution can be a citric acid, vinegar or other non-hazardous solutions.
Any solution used should be thoroughly rinsed out afterwards.
Fill the rest
of the quartz with water.
Step 6
: Let the cleaning solution remain in the quartz for at least 10-20 minutes.
Step 7:
Manually
turning the wiper may greatly assist the cleaning process. To
do this, remove the motor assembly (see Step 7 in the Disassembling the Unit
section) and turn the wiper shaft with a flat-bladed screwdriver
(counterclockwise while looking at the shaft).
Step 8:
Drain the unit and inspect the quartz sleeve. If clean, flush the unit with
clean water. If fouling remains, repeat procedure.
