SECTION 8: MAINTENANCE
First Aid Measures:
In case of skin exposure, to cleaning agent, remove
by washing with soap and water immediatel
In case of eye exposure to cleaning agent wash
eyes for several minutes with water and contact a
physician immediately.
In case of ingestion of cleaning agent contact
physician immediately.
Procedure
1. See Page 24 for quartz sleeve removal instructions.
2. Inspect quartz sleeve and clean as needed with a
soft, clean cloth and mild dish detergent.
3. For calcium deposits use muriatic acid to dissolve/
clean deposits. See next page for procedure.
4. Rinse quartz sleeve thoroughly with clean
freshwater.
5. See Page 10 for quartz sleeve installation
instructions.

UV Vessel Cleaning
Purpose
Over a period of time, dissolved matter can build
up on the surface of the quartz sleeves and the
interior of the vessel aecting the eciency of the
UV disinfection process. Due to fouling, the available
intensity will decrease continuously until the quartz
sleeves are cleaned.
NOTE: The use of the optional wiping system merely
helps to decrease the frequency of the manual
cleaning cycle.
Please be aware that such a decrease also may be
caused by aging of the UV lamps or changes in the
water quality (UV transmission). Repeat of visual
inspections of the UV Sensor or of some example
quartz sleeves will help to determine the necessary
cleaning intervals needed. The removal of this build-
up (calcium, etc.) can be carried out with a cleaning
pump. Pentair recommends the use of muriatic acid
to chemically clean the quartz sleeves. Materials
within the vessel chamber are highly resistant against
this acid.
Frequency
When necessary.
Parts and Equipment Required
• Cleaning Solution of Muriatic Acid and Freshwater
(1:4 ratio)
• Acid-Resistant Transfer Pump
• Acid-Resistant Hose (used to transfer the cleaner
from the container to the UV vessel)
• Fittings to connect to vessel
• Acid-Resistant Bucket
• Clean Cloth
• Acid-Resistant Drop Cloth
• Acid-Resistant Gloves
• MSDS Sheet
• Personal Safety Equipment
General risk due to pressurized piping and UV
vessel!
General risk due to caustic cleaning agent!
Quartz Sleeves are fragile and potentially
dangerous if broken. Handle with care.
First Aid Measures:
In case of skin exposure, to cleaning agent remove,
by washing with soap and water immediately.
In case of eye exposure to cleaning agent wash
eyes for several minutes with water and contact a
physician immediately.
In case of ingestion of cleaning agent contact
physician immediately.
