engaging the lock tab of the E-Z Flo+ regulator or the
latch on E-Z Flo C5 regulator and rotating the

sanitizing or disinfecting cleaner, wipe the external

the regulator opening (see Figure 4-1). If excessive dirt
or soil is present, forward the regulator assembly to

Figure 4-1 Cleaning the mask-mounted regulator
Follow the user instructions for the cleaner. A specific contact time may be required for sanitizing or disinfecting
before rinsing.
6 Set the regulator aside for the required contact time prior to rinsing. The hypochlorite solution and the aqueous
solution of iodine require a 2-minute contact time.
7 Using gently running tap water or a spray bottle with drinking water, rinse the regulator inside and out.
8 Shake excess water out of regulator. Completely air dry the regulator before use.
9 If the regulator was disconnected from the air supply for cleaning, reconnect and open the purge valve to remove
any moisture from regulator spray bar. Close the purge valve.
