RECOMMENDED TOOLS: Two 1/4" diameter anchors suitable for supporting filled eyewash
(approximately 80 pounds) and tools needed to install these anchors.
LOCATION OF UNIT: The Model 7501 Portable Eyewash should be installed in close
proximity to potential accident areas. It should be clearly identified, free from obstructions and
easily accessible.
INSTALLATION INSTRUCTIONS
Step 1: Wall mount with “J” Bracket (see Installation Drawing). Eyewash nozzles should
be between 33 inches (83.8 cm) and 45 inches (114.3 cm) above the floor when
eye wash arm is in the active (lowered) position.
IMPORTANT:
Filled eyewash unit is heavy (approximately 80 pounds). Wall bracket anchors or
shelf must be strong enough to support the filled eyewash and the weight of a
worker leaning on eyewash.
Step 2: Fill up to fill line and place on level surface if possible. If installed as indicated,
eyewash unit will provide 15-minute duration of flow.
Step 3: Take proper precautions to help prevent the growth of potentially harmful
bacteria in eyewash tanks. (Refer to Maintenance Instruction).
OPERATING INSTRUCTIONS
Instruct all employees in the use of this Emergency Eyewash. Personnel should be assigned
to check eyewash liquid level daily.
Step 1: Lead patient to nearest eyewash station. Seconds can make the difference in
preventing serious eye injury.
Step 2: Pull yellow eyewash arm firmly. Eyewash arm will drop to activate eyewash.
Step 3: Lower head until eyes enter eyewash stream. Use thumbs and forefingers to hold
eyelids open. Flush for 15 minutes.
Step 4: Seek qualified medical attention immediately.

MAINTENANCE
Step 1: Self contained eyewash equipment shall be visually checked to determine if
flushing fluid needs to be changed or supplemented.
Step 2: Take proper precautions to help prevent the growth of potentially harmful
bacteria in eyewash tanks. We recommend either of the following procedures:
A. Use suitable Bacteriostatic Preservative to help prevent the growth of bacteria in
eyewash tank. Eyewash tank should be drained, flushed and refilled with clean
potable water and Bacteriostatic Preservative as directed by the preservative’s
manufacturer.
B. Drain, flush and refill portable units with clean potable water at least once every
week. Thoroughly cleanse tank at least once every month.
NOTE: Acanthamoeba survive mild chlorination and are commonly found in tap water.
Bacteriostatic Preservative will prevent the growth of Acanthamoeba. Hot water,
158º F (70º C) or hotter will destroy Acanthamoeba but must be allowed to cool
prior to use in eyewash units.
