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 affecting the efficiency of the UV 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 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 Protective 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.
WARNING: If a sleeve nut is removed when there
is dynamic water pressure inside the UV system, the
lamp sleeve will eject from the end plate with enough
force to cause personal injury.
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.
