Machine Overview
Screened Float
If the recovery tank (C) is overfilled or a large amount of foaming
is present, the screened float (B) blocks the vacuum intake inside
the tank protecting the vacuum motor and internal electronics from
water damage. It is essential to keep the float in working order
through regular maintenance.
The float should be cleaned daily by thoroughly rinsing with a
hose. Removal of the screened float is not necessary for daily
maintenance.
At least once a month the screened float should be completely
removed, cleaned, and checked for any damage to the seal or
metal screen.
WARNING: Damage to the machine may occur if operated
without the screened float properly in place.
