5.2 Manual Mechanical Wiping System
(MMWS) (Optional)
Description
The TrojanUVLogic
™
system can be provided
with a Manual Mechanical Wiping System
(MMWS). Please refer to system specifications
as listed at the front of this manual to see if your
system is equipped with manual wiping.
The MMWS uses food grade rubber wipers
mounted into stainless steel collars, placed
around each of the Quartz Sleeves. The Wiper
Housings for all Sleeves are mounted together
onto a common Wiper Assembly. The Wiper
Assembly is driven back and forth by hand using
an external handle.
The operator must ensure that the Wiper is
returned to its home position. This is
accomplished by ensuring that the Wiper Handle
is returned to its original position after wiping.
Do not force ; at no time should the Handle
come in contact with the Strain Relief on the End
Cap.
Maintenance
