SERVICE
Disconnect and lock out electrical power before servicing.
No welding should be performed inside without fire protection.
Avoid contact or exposure to collected liquids during servicing.
Inlet hopper / impact separator
For applications where both liquid and particulate are collected, it may become
necessary to clean the hopper and impact separator (if supplied).
• Access the hopper and impact separator through the access door.
• Remove the first stage filter, the filter element and the filter retention system.
• Clean the hopper and impact separator by scraping the particulate out.
Be careful to keep the particulate out of the drain.
Collection bottle
If the collection bottle requires cleaning, remove it from the impact separator drain.
Clean the collection bottle and faucet and re-install (see figure 12).
Only remove the collection bottle when the mist collector is turned off.
Change of filter elements
a. First stage filter
This is a permanent filter, which is designed to last the life of the WSO Flex mist
collector. This filter may need to be periodically cleaned.
Access the first stage filter through the access door. Remove it out of the unit by
pulling it out. The first stage filter can be cleaned by rapping it over a waste container
to dislodge particulate.
If further cleaning is required, wash or soak, rinse and dry the first stage filter.
An optional polypropylene first stage filter is available for applications involving heavy
liquid loading.
Because of temperature limitations of the polypropylene filter, high
temperature cleaning methods such as steam cleaning should not be used.
Do not operate the mist collector without the first stage filter installed.
Significant reduction in filter element life may result.
