CONTROL CONSOLE BATTERY
1. To replace the battery in the Control Console, position the respira-
tor so the Control Console battery cover is accessible as shown in
FIGURE 10.
2. To remove battery cover, first loosen all 4 cover screws 1 or 2
turns each, then fully loosen the screws so the cover can be re-
moved. Carefully remove cover and set aside.
3. Remove used battery from battery compartment by lifting bottom
of battery, using a finger or the flat blade of a screw driver, being
careful not to damage battery contacts or sealing rib around bat-
tery compartment.
4. Install one (1) fresh new battery. Use only one of the following:
Eveready Alkaline No. 522 or EN22, Duracell Alkaline No. PC1604
or MN1604, or for increased service life use Ultralife Lithium Battery
No. U9VL. Be sure battery is installed with the terminals positioned
as indicated by symbols on label in bottom of battery compartment.
5. The battery cover must be installed so that it is water tight after
replacement. Clean the sealing rib around battery compartment
and sealing face of the cover, shown in FIGURE 11, by wiping with
a clean damp cloth to remove any dirt or foreign matter which
might prevent a proper seal. Check cover seal for tears or cuts. If
damage is found, remove respirator from service and tag for re-
pair by authorized personnel.
